Fiberglass production: manufacturing technology, how to choose a plant, machines and other equipment, how to dispose of waste materials

Insulation is essential for maintaining a warm and comfortable environment in our homes. Fiberglass is one of the most widely used insulation materials because it is both inexpensive and effective. But have you ever wondered about the manufacturing process of fiberglass insulation? We will explore the manufacturing process, how to choose the best production plant, the machinery and equipment used, and the crucial factors to take into account when disposing of waste materials as we delve into the fascinating world of fiberglass production.

Let’s start by learning the mysteries surrounding the technology used in the production of fiberglass. In essence, fiberglass is made of tiny glass fibers that have been painstakingly woven into a dense, flexible substance. In a high-temperature furnace, raw materials such as silica sand, limestone, and soda ash are melted to start the production process. Glass is melted and then continuously formed into fibers by being forced through tiny holes. After being quickly cooled to solidify, these fibers are what give fiberglass its distinctive fibrous structure.

Having gained a basic understanding of the process of making fiberglass, the next step is to select the most suitable production plant for your requirements. It’s crucial to take into account aspects like the plant’s production capacity, quality control procedures, environmental sustainability policies, and compliance with safety regulations when choosing a fiberglass manufacturing facility. A successful partnership can also be ensured by evaluating the plant’s standing in the industry and its history of producing high-quality goods.

Of course, without the right tools and machinery, the manufacturing process couldn’t be finished. For processes like melting raw materials, extruding fibers, cooling and solidifying the fibers, and cutting and packaging the finished product, specialized machinery is needed in the production of fiberglass. Investing in cutting-edge machinery guarantees the consistent quality of the fiberglass insulation while also increasing productivity and efficiency.

The production of fiberglass requires careful consideration of waste material disposal, just like any other manufacturing process. Although fiberglass is a recyclable material in and of itself, during the manufacturing process certain waste materials, like extra trimmings and offcuts, may accumulate. In order to reduce environmental impact and adhere to regulations, it is imperative to employ appropriate disposal techniques, such as recycling, repurposing, or incineration in controlled environments.

To sum up, the process of producing fiberglass necessitates a complex fusion of machinery, environmental consciousness, and technology. We can guarantee that there will always be high-quality fiberglass insulation available for our homes and buildings by comprehending the complexities of the manufacturing process, choosing the best production facility, making quality equipment investments, and putting appropriate waste disposal procedures into place.

Preparation of fiberglass cloth

The glass fabric is cut to the matrix’s dimensions using a dense cardboard template. The product may, however, use the cutting of fiberglass fabric comprised of multiple separate parts if it has a complex shape.

The necessary number of material layers are prepared and stored in an easily accessible location in the order that they are molded in the matrix, depending on the thickness of the part. It’s important to closely monitor the material’s storage conditions if there is a few-day pause between the cutting of glass fabric and product molding.

Equipment for recycling garbage: 4 options

Starting a recycling company benefits society and the environment in addition to the business owner’s bottom line. For example, Russia’s activity in this area is not as developed as it is in European nations.

As a result, entrepreneurs and investors are becoming increasingly interested in this subject.

Modern garbage processing technologies have made it feasible to recover recyclable materials from solid domestic waste (MSW) in addition to disposing of it. Many nations support this idea, which has led to the emergence of an increasing number of businesses involved in this kind of activity.

Investing in waste recycling equipment can yield financial benefits in addition to bettering the city’s environmental state. Garbage recycling can be done in a variety of ways because this field is always evolving.

Main areas of waste recycling

Waste used to be simply removed from the town and buried a few years ago. However, as the environment continues to deteriorate, people are under pressure to find a solution.

Waste needed to be disposed of.

In order to address this issue, they started developing waste disposal machinery and coming up with fresh ideas for using wastes. As a result, several significant waste recycling fields arose.

What is fiberglass and materials based on it?

The process of creating strong and lightweight products using fine glass fibers and different resins is known as fiberglass manufacturing. Glass fiber has been around since the beginning and is used as an insulator in appliances and buildings as well as a reinforcing agent for plastics. When a lightweight, highly durable, and scratch-resistant material is needed in manufacturing, fiberglass is used.

The most widely used method for producing goods made of glass fiber-reinforced plastic among the glass fiber production processes is glass fiber molding. The material known as fiberglass is created by extruding molten glass through incredibly tiny holes in a tool to create formations that resemble threads, which are then woven together to create a rough cloth or patch.

By pressing or heat treating the fibers, plastic resin is mixed with them. Numerous fiberglass products, such as panels, race car enclosures, electrical circuit boards, equipment supports, and many more, are made using this process.

The temperature of fiberglass does not cause it to expand or contract. In addition to being chemically resistant, having a high strength-to-weight ratio, and not absorbing water, it also serves as an electrical insulator. Different kinds of fiberglass products are produced by fiberglass manufacturers.

Types of glass fiber and fiberglass resin

Fiberglass materials and products are made from various types of glass fibers and resins, each having unique properties and uses as well as strengths and aesthetics.

Seven basic types of fiberglass exist. The most popular kind of glass fiber reinforced plastic is called E-glass; A-glass has a low boron oxide content; E-CR-glass is highly acid resistant; C-glass is used to make staple fibers; and D-glass has a dielectric constant and high acid resistance.

S-glass has an extremely high tensile strength, while R-glass is renowned for its remarkable mechanical qualities. These kinds of glass fibers are combined with thermosetting resins, most commonly polyester or epoxy resin.

Casting, laminating, and molding are all done with resins. Epoxy resin is used in high-strength, weight-critical applications because of its higher performance at a higher cost. Polyester resins are more widely used, less expensive, and resistant to corrosion.

Glass fiber manufacturing process

Centrifugal molding, closed molding, and open molding are the three primary techniques used to create glass fiber. A layer of gel coat is applied and cured in a single-piece mold or structure during the open molding of glass fibers process. The glass fibers and sprayed resin are allowed to cure after being layered in the mold. Compared to the other two processes, open molding generates more emissions.

The first gel coat in closed molding is applied in a two-piece mold. Fibers are sprayed or inserted into the mold’s enclosing area over the gel coat in the form of chopped fibers or laminated sheets. After being vacuum sealed in a mold, the part is cured, and pressure is applied to the mold to inject the catalyzed resin.

Gelcoat is applied to the sides of a revolving cylindrical mold in centrifugal molding. Catalyzed resins with short fibers are sprayed into the mold layer by layer until the required thickness is reached.

Tanks and other cylindrical products are molded using centrifugal molding. The finished products are then trimmed and taken out of the mold in all procedures. Nowadays, the most popular fiberglass product is most likely corrugated fiberglass.

It is robust and can be transparent to let light into buildings or solid colored, usually green. It is mostly used in construction for siding or roofing, though greenhouses and sheds are also frequently built with it.

Typically, corrugated fiberglass is made up of two layers that are fused together. A sturdy, weather-resistant resin surface makes up the outer layer. Tanks and other cylindrical products are molded using centrifugal molding.

The finished products are then trimmed and taken out of the mold in all procedures. Nowadays, the most popular fiberglass product is most likely corrugated fiberglass.

Advantages of fiberglass

As the main substitute for fiberglass, aluminum, is frequently inferior to fiberglass in many cases. The process of pultrusion

Fiberglass profiles, when compared to comparable stamped aluminum profiles, have a number of advantages. (Pultrusion is a technology for manufacturing highly fiber-filled composite parts with a constant transverse structure).

Glass fiber that has been pultruded exhibits exceptional resistance to a variety of chemicals. Aluminum profiles weigh roughly 70% more than fiberglass profiles, despite having the same density. Aluminum is a conductor, whereas pultruded glass fiber has a high dielectricity and is non-conductive.

Because fiberglass has a much lower thermal conductivity than aluminum, it is a far better insulator. Aluminum needs to be painted, anodized, or pre-finished; however, pigment added to fiberglass resins can color the entire piece.

Fiberglass is frequently used for radar and antenna housings and supports because it is transparent to radio waves and EMI/RFI transmissions. Due to its high reflectivity, aluminum is not a good choice for these kinds of applications.

Pultruded fiberglass molds don’t require welding or torches and are easily constructed in the field using standard carpentry tools.

Lastly, aluminum deforms readily whereas pultrusion fiberglass mat forms distribute impact loads uniformly.

For a variety of products, fiberglass-reinforced plastic is a great building material.

The density and adaptability of fiberglass-reinforced plastics and aluminum are identical, but there are some significant distinctions. Fiberglass or aluminum may be more appealing for certain applications.

• Lighter – Compared to its main alternative, aluminum, fiberglass is typically about 70% of the weight for similar density and strength. This ratio also compares favorably to any number of other plastics, composites, and metals.
• Non-reflective – although not for all applications, in many cases the non-reflective properties of fiberglass for light, radio and other waves make it an ideal material.
• Uniform force distribution – one of the unique properties of fiberglass is how it distributes force. While it may not be ideal for all applications, in many cases it is very valuable.
• Easy to make – compared to the process of making aluminum and other comparable materials, fiberglass is extremely easy to make and customize to your needs. This includes pigmentation, secondary coatings and many other considerations.
• Excellent insulation – The unique thermal properties of fiberglass make it an excellent insulation solution for a wide range of applications. It remains a staple insulation material in construction, HVAC and similar industries.

Application of fiberglass

Fiberglass has a wide range of applications due to its versatility in various industries. It can carry out a wide range of structural tasks that would typically require the use of metals or pure plastics, such as but not restricted to:

• Construction – material for the main insulation in some forms and as the main structural material in others.
• Production of vehicles – a popular material for manufacturing hulls of boats, cars, airplanes and various other vehicles due to its strength-to-weight ratio.
• HVAC – It is used as a primary insulation material in the form of solid panels, as well as for seals and spray coatings.
• Sports equipment – Fiberglass has become a popular material for safety gear, equipment such as poles, hockey sticks, bows and many other items.
• Storage Tanks – Many types of storage tanks can be constructed using fiberglass as the base material. Fiberglass tanks are most commonly used as chemical storage tanks, septic tanks, and similar vessels.
• Piping – fiberglass pipes offer a number of advantages over traditional plastic or metal pipes, making them an ideal choice for certain applications.
• Medical – a key component of medicine for the same reasons as in sports equipment. Fiberglass parts are particularly common in orthopedic devices.
• Telecommunications. Low RF permeability and low signal attenuation are used to shield antennas or to mask equipment when signal permeability is undesirable or not a factor.

A specific type of glass fiber can be identified using a number of key descriptors. The primary factors influencing the fundamental characteristics of the completed fiberglass product are the type of resin and the basic fiberglass material utilized in the manufacturing process.

Classification of glass fibers

Based on the constituent parts and characteristics of the material, fiberglass is divided into several general categories.

• E-glass – Standard fiberglass reinforced glass fiber reinforced plastic.
• A-glass – specialty glass with a reduced concentration of boron oxide.
• E-CR glass – A glass fiber that provides exceptionally high acid resistance.
• C-glass – Used for the production of staple glass fibers.
• D-glass is a glass fiber characterized by a relatively high dielectric constant.
• R-glass – fiberglass designed for high mechanical performance.
• S-glass – a glass fiber that provides exceptionally high tensile strength.

Resins

Most glass fiber products have a choice of thermosetting resins in addition to the basic glass fiber material. The majority of the time, polyester- or epoxy-based resins are utilized, though there are other options as well.

• Polyester resins – low-cost, widely used resins with high resistance to corrosive attack. The most common type of resin used to make glass fiber.
• Epoxy resins – high performance resins used in applications requiring exceptional strength-to-weight ratios. More expensive than polyester resin.

Other terms

When discussing fiberglass for particular applications or specifications, you might run into some common terms in addition to the fundamental categories and classifications of the material.

• Fiberglass Pipe – fiberglass reinforced plastic piping. High corrosion resistance.
• Fibercast Pipe – refers to a particularly popular family of fiberglass pipes for chemical processing and transportation applications.
• Fiberglass Reinforced Plastic (FRP) – plastics combined by thermoforming plastic with extruded glass fibers. Often referred to simply as fiberglass or GRP (glass fiber reinforced plastic). Typically, but not always, what is meant by the term "glass fiber" in industry.
• Structural fiberglass – strong fiberglass shapes, boards and components used in construction and other industrial manufacturing processes.

Equipment used

A fiberglass factory may contain a wide range of standard industrial equipment, but two special mechanisms are essential to the creation of fiberglass products:

• Molds – each type of fiberglass molding process requires a unique mold designed to this standard. Any particular production team may be equipped with some or all types of molds, depending on the specialization and size of the operation. For example, a manufacturer working exclusively with tubing may only need regular access to a centrifugal form.
• Fiberglass cutting systems – regardless of the molding process used, fiberglass products almost always require trimming and cutting to meet final specifications. This has typically involved the use of specialized fiberglass cutting machines, which may provide a greater or lesser degree of automation. More complex assemblies can complete the entire cutting process without human intervention, while others may require step-by-step setup and manual adjustment.

Understanding the manufacturing process of fiberglass is essential when it comes to home insulation and heating. This substance is essential for maintaining the warmth and energy efficiency of homes. There are many factors to take into account, ranging from comprehending the manufacturing process to selecting the ideal production facility, machinery, and equipment. Furthermore, handling waste products from the fiberglass industry is crucial to the sustainability of the environment. In this post, we explore the technology underlying the production of fiberglass, offer advice on choosing the best equipment and production facilities, and go over efficient waste disposal techniques. Homeowners and business professionals can maximize environmental impact while increasing energy efficiency by making educated decisions by understanding these critical factors.

Manufacturing fiberglass products

Glass mats, roving, polyester resin, and fiberglass filler combine to form fiberglass, a composite material.

Fiberglass products can be made in a variety of ways, from inexpensively with no expensive equipment and skills to expensively with expensive equipment.

Filler material can be fiberglass, fiberglass mats, different types of fiberglass fabrics, or ground roving (for sprayed fiberglass products). As a component of the binder, several polyester resins are employed.

Home craftsmen in the Soviet era used epoxy resin to create fiberglass items because it was easily accessible and widely available in stores. Nowadays, a range of polyester resins that are less expensive are largely replacing epoxy resins. Vinylester, orthophthalic, and isophthalic resins are examples of polyester resins. Because orthophthalic resin is so inexpensive and because most fiberglass products don’t require the properties of vinylester and isophthalic resins, it is the most widely used type of resin in the production of fiberglass plastics. However, the use of isophthalic resins has increased significantly in spite of this.

Iso-phthalic resins have higher corrosion resistance and resistance to various solvents, they also have higher strength and impact resistance. Iso-phthalic and vinylester resins have higher adhesion properties than orthophthalic resins. At the same time vinylester resins surpass isophthalic resins in chemical and corrosion resistance, they are also characterized by higher elasticity, which is a significant advantage of their use in products with high physical load. Although quite often the use of vinylester resins is not justified, in most cases it is possible to get by with the use of isophthalic resins with the use of properly selected fillers and observing the technology. Vinyl ester resins are used in products with high requirements to maintain strength at high temperatures or resistance to chemicals and corrosion. The disadvantages of vinylester resins include their higher cost compared to orthophthalic and isophthalic resins, as well as a significantly shorter shelf life. Often vinylester resins come to the market unaccelerated, which requires independent introduction of gas pedal into the resin, this is complicated by the fact that in the form of gas pedals used cobalt naphthenate together with dimethylaniline, which is quite dangerous carcinogen.

The technologies used to manufacture fiberglass plastics based on vinylester resin are rather complex; in order to work with vinylester resin, it might be necessary to add extra gas pedals to the resin. This can be very challenging for novice fiberglass product manufacturers to work with.

Many manufacturers have a question about the possibility of diluting polyester resins, with what and how? It is not desirable to dilute polyester resins unnecessarily, but still possible. Acetone can be used as diluents in the amount not more than 5% by mass, the use of acetone can lead to the formation of finely porous structure of the resin surface, it happens because it does not participate in the curing of the resin and appears "clogged" in the resin. Also its use can lead to cracking and shrinkage. Due to intensive evaporation acetone cools the surface of the resin during curing, which increases the curing time. The use of acetone as a solvent for polyester resins is rather controversial. It is more correct to use liquid styrene monomer as a diluent, which is originally a part of polyester resins. It can be added up to 15%, although usually the proportions are no more than 5%.

Fiberglass is made using a number of techniques:

• hand molding method
• spraying method
• winding method
• injection method
• pultrusion method

Manual molding method. The essence of this method is the layer-by-layer application of reinforcing material on the mold or in the mold itself, each of the layers is impregnated with resin, which is applied with a special brush or roller. After applying the layers of reinforcement cloth with resin, additional rolling is done to distribute the resin more evenly and compact the layers, while removing the air, t.к. If air remains in these places, the product will be soft and may be pressed through during operation. The advantages of this method: low cost, ease of manufacture of the product, the possibility of using a variety of resins and fillers resistant to resins. This method is suitable for the production of small batches of products or single exclusive fiberglass products.

Spraying method. In this method, the resin is applied with a special gun, which is equipped with a special knife for shredding glass filament. Shredded fiberglass thread is mixed with a jet of resin and applied to the surface of the product to be manufactured. Then, as in the previous process, the layers are rolled with a sealing roller to remove air residue and further seal the layers. The pros of this method – no need for cutting fiberglass cloth or fiberglass mat, high speed of production, low amount of wastes. This method also has significant disadvantages – heavy weight of the product because of the large amount of resins, reduced physical and mechanical properties of the product because of the lack of long reinforcing fibers, very harmful production conditions due to the suspension of small particles of resins and glass fiber, which requires the use of a good ventilation system and personal protective equipment for workers in the production area.

Winding method. In this method, the fibers are passed through activated resin baths and after impregnation they are wound onto a rotating matrix. The thickness and angle of the winding is fully controlled by the speed of the cart with which the fibers are fed. The advantages of this method are high speed of the production process, high strength of the product, low weight of the product, low cost of the materials used and a fairly wide temperature range of operation. The disadvantages include expensive equipment, the possibility of manufacturing products only with a closed form of rotation. All polyester and epoxy resins, fibers and fillers can be used in this production method. Pipes produced by this technology are very popular in the chemical and oil and gas industries.

Injection method. Glass fiber material is pre-cut, then it is placed in a matrix (mold) and pressed with a punch, and then resin is injected (so-called injection). After complete impregnation of the material with resin, injection is stopped and the material remains until it is fully set in the matrix. Advantages of this method of production of fiberglass – the possibility of obtaining products of very accurate size, glossy surface of the product both inside and outside, high content of glass fibers provides the product with a fairly low specific weight, and naturally a low percentage of waste production. Cons – Expensive and difficult to produce. It is profitable to produce products in large quantities by this method.

Pultrusion. Pultrusion is the continuous drawing of resin-impregnated fiberglass materials through a specially designed die that is heated to between 120 and 150 degrees Celsius. High pressure and temperature cause the material to change into a reasonably strong product. The benefits of this production method include automation of the process, low cost materials, and high speed. One major drawback is the expensive equipment required. Fillers are not used in this production process.

How to use fiberglass in households and in construction

In private, this substance is most frequently employed in three situations:

• to repair rods;
• for repairing tools;
• for reinforcing structures and planes and for sealing.

Repair of fiberglass rods

It calls for a high-strength resin grade (ED-20 or analog) and a fiberglass fabric sleeve. This article goes into great detail about the process technically. Because carbon fiber is significantly stronger than glass fiber, it should be noted that the latter should not be used to repair impact tools (such as hammers, axes, and shovels). Simultaneously, it is feasible to create a new handle or inventory handle out of fiberglass, such as the fender of a motorcycle block.

Practical guidance. Your tools can be enhanced with the use of fiberglass. After 15 minutes, squeeze the impregnated fiber in your hand by wrapping it around the handle of a functional hammer, axe, screwdriver, or saw. The layer will precisely conform to the contours of your hand, significantly improving comfort while working.

Inventory repair

The following plastic products can be sealed and repaired thanks to fiberglass’s airtightness and chemical resistance:

1. Sewer pipes.
2. Construction buckets.
3. Plastic barrels.
4. Raindrops.
5. Any plastic parts of tools and machinery that are not subjected to heavy loads.

Fiberglass repair: a step-by-step demonstration

One essential quality of "homemade" fiberglass is that it is precisely machined and retains stiffness well. This implies that a plastic component that is completely destroyed can be made new or repaired using canvas and resin.

Separation layer

Once the product has gained strength, a separating layer is applied to the matrix mold’s surface to ensure that it can be safely removed. The material used to create the release layer is frequently auto wax or Teflon gel.

Bolvan matrix:

Any matrix creation requires a dummy. It is an exact replica of the future product’s shape, functioning as a prototype. The bolvan needs to be of the highest caliber. Errors pertaining to dimensions, form, surface irregularities, and roughness are not acceptable.

Although it is more frequently composed of any rough material, the dummy matrix can be made of the same material as the finished product. For instance, matrix bollwans are frequently employed in the production of:

Matrix bolvans must be puttyed, painted, and coated with specific varnishes after completion. This will result in a glossy product surface and remove the "boil-off" effect by producing an extremely smooth, non-porous surface.

CNC (computer numerical control) milling machines are used to produce accurate replicas with low dimensional error when working with a range of materials to create complex bollards.

Production technology

Ordinary broken glass is used as the raw material for glass fiber.

In addition, sand, limestone, and supporting elements are utilized.

Phases involved in making glass filaments:

1. Raw materials are melted.
2. The resulting viscous melt is forced through hundreds of microscopic holes under high pressure. This gives the material a thread-like shape.
3. They are cooled and wound on special spools.

An oiling agent is used to treat the completed glass fiber.

The lubricant helps to fuse the fibers into a complex filament and gives the fiber resistance to stretching and friction.

Filaments can be made from materials other than glass melt. Additionally, rounded glass that has been fused first is used. The cost of this technology is much higher.

Areas of use

Application is feasible in nearly every field:

• for the production of sports equipment (including surfboards), machinery, translucent roofing panels;
• for noise insulation of airports, subways, train stations;
• for thermal and electrical insulation of buildings;
• as a reinforcing base for fiberglass plastic;
• For waterproofing roofs and small vessels;
• as insulation for ventilation ducts;
• in the construction of cars and airplanes (base for elements);
• for sewing covers for industrial equipment, screens and fire curtains.

Electrical communications cables are also wrapped with this material.

How to open a business?

Creating a business plan is the first step. Following that, you can go ahead and buy raw materials and equipment.

Purchase of equipment

It is expensive to set up your own factory to produce glass filaments. Purchasing will be required in order to:

• centrifugal blowing machine; its price is in the range of 80-180 thousand rubles. rub.;
• Drying container (with polymerization); it costs 100-150 thousand. rub.;
• chamber for deposition of fibers (50-90 ths. rubles.);
• end conveyor (40-80 thousand. rub.).

A chopping machine or cross-cutting knife is also required. There will be a 15–25,000 cost. rubles.

The most well-known companies producing the aforementioned equipment are:

• CampenMachineryA/S;
• Sib Controls;
• "BusinessStroy-NN".

You have two options: either select lines and machines that are already on the market, or order their manufacture to meet your specifications.

You can think about boo’s options if you don’t have enough money.

Where to get raw materials?

Glass fiber creation requires the following:

• Glass sludge is the main component of production;
• dyes, clarifiers and other auxiliary chemicals.

Acquiring the correct quantity of raw materials is not the hardest thing to do.

Glass waste is easily sourced from recycling facilities and glassware acceptance locations. As a last resort, you can set up a location where people can be collected yourself.

Obtaining chemical reagents is also not too difficult. CJSC "Khimservis" is one of the biggest and most well-known domestic suppliers of these goods.

Requirements for the premises

Glass fibers cannot be made without the use of chemicals. Glass dust is also an inevitable part of life. Consequently, the production room has to be:

• quality purification equipment for the water supply system;
• good ventilation; you will have to spend on masks with respirators for workers;
• fire alarm system.

You will need to make an investment in a heating system because the production area should never be colder than +15 degrees Celsius during business hours.

Producing fiberglass requires a sizable warehouse. It must have a minimum area of 200 m2.

Ideally, you should have two of these rooms: one for completed goods and one for raw materials.

Naturally, ventilation and fire safety equipment must also be installed in warehouses.

Personnel

Initially, ten to twelve workers will be sufficient for the production of glass threads.

Never operate without "white-collar" employees such as:

• technologist-consultant; he selects the optimal equipment and auxiliary materials to optimize and reduce the cost of production, advises on how best to organize the work process;
• an accountant for civilized communication with the tax authorities;
• purchasing and sales manager;
• A secretary, whose main duties are to "destroy" current affairs.

Apart from the regular employees in the shop, it will need to hire:

• several movers unloading and loading the company"s warehouses;
• drivers – they transport raw materials and goods;
• cleaners.

Where to market finished products?

Glass fibers are highly sought after by:

• state organizations and private companies engaged in the construction of roads, industrial and infrastructure facilities, residential buildings;
• Companies providing repair services;
• large construction stores and hypermarkets.

Whether it is possible to dispose of waste?

Although not categorized as hazardous, waste from the production of fiberglass must be disposed of.

The principal ones consist of:

• unidirectional and coarse "inflexible" glass fibers;
• fiberglass scraps.

They can be used to create foam glass and other materials that are piercing and heat-insulating.

Paperwork

You must obtain multiple special authorization documents and register with the tax office before you can begin producing glass filaments. To the tax office must be sent a special application.

It ought to state:

• What form the tax reporting will take;
• OKVED code.
• form of legal activity (LLC or individual entrepreneur).

The choice between an LLC and a sole proprietorship is yours. It makes more sense to choose an LLC if a sizable investment in the business with subsequent scaling up is anticipated for a variety of reasons.

The fiberglass industry is classified under items 1, 14, and 23 of Section C of the Classifier of Business Activities (OKPD), where:

• 1 – glass and glass products;
• 14 – glass fiber itself;
• 23 -mineral products (non-metallic).

Apart from submitting an application to the tax office, obtaining special permits to carry out activities will be required from:

• sanitary service;
• fire inspectorate;
• the commission that is responsible for labor protection.

• certificate, which confirms that the equipment used meets the State Standard;
• A special document certifying that the finished product complies with GOST;
• License for the use of explosive production facilities.

Working with waste from the production of fiberglass also requires a license.

It permits the handling, treatment, transportation, and storage of wastes that fall into hazard classes 1-4.

The federal law (N-99, Article 9) states that there is no time limit on the validity of this kind of license.

Technologies we apply

– One of the most popular processes for producing fiberglass goods is contact molding. It is frequently employed in the production of large-sized, intricately configured parts that do not require a large load. There are two methods for carrying out production: spraying and hand laying.

– Medium and large batches of plastic products are produced using the RTM (injection method) technique, which is carried out with equipment made up of a matrix and a response mold. During the manufacturing process, a layer of fiberglass is positioned between them. After filling the closed mold with a polyester resin and hardener mixture, the final product is machined if needed.

– Vacuum film is used during the vacuum infusion process. In this instance, a vacuum forms in the mold’s working cavity, causing the polyester resin to seep into the glass wool or fabric. With this technique, you can produce parts with extreme precision and excellent surface quality.

Here are some examples of how the aforementioned technologies are being used.

Characteristics of structural glass fibers

Special aluminoborosilicate glass yarns are woven together, coated with paraffin emulsion and a direct oiling agent, and then used to create structural fiberglass fabrics. High strength and low weight are the distinguishing features of structural glass fibers. The high qualities of structural fiberglass fabrics enable their application in a variety of industries, including shipbuilding and auto construction.

Electrical and electronics engineering

Many different types of electrical insulating materials are made from glass fiber.

Because glass is a superior dielectric, its yarns are used to create unique woven materials that are used as electrical energy conductors and insulators for conductive structures.

Multilayer printed circuit boards for electronic devices are made from copper foil-coated glass-textolite, which is a blend of glass fibers and epoxy resins.

Another glass fiber made of silica glass is used in electronics, where it is known as fiber optics.

Medicine

Certain types of implants and prosthetics for different body parts can be made from fiberglass without compromising one’s health. Dental prostheses are made with glass fiber in the field of dentistry. Glass fiber is used as a primary or secondary construction material in a variety of medical instruments and equipment. The same high purity glass fiber is a key component of surgical laser scalpels.
