Fiberglass is not made of glass.
Glass fiber is made of pyrophyllite, quartz sand, limestone, dolomite, boronite, and boronite as raw materials through high-temperature melting, wire drawing, winding, weaving and other processes. Its main components are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc. According to the alkali content in the glass, it can be divided into alkali-free glass fibers (0% to 2% sodium oxide, which belongs to aluminum Borosilicate glass), medium-alkali glass fiber (sodium oxide 8% to 12%, which belongs to boron-containing or boron-free soda-lime silicate glass) and high-alkali glass fiber (more than 13% sodium oxide, which belongs to soda-calcium silicate glass) silicate glass).
Fiberglass is an inorganic non-metallic material with excellent performance. There are many kinds. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. Difference. The diameter of its monofilament is several microns to more than 20 microns, which is equivalent to 1/20-1/5 of a hair, and each bundle of fiber precursors is composed of hundreds or even thousands of monofilaments. The glass fiber is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and other national economy fields.
Glass wool is a plate-shaped product that is processed by centrifuging molten glass into fibers and solidified by adding an environmentally friendly formula binder based on thermosetting resins. The slender glass fiber has a low thermal conductivity and can trap air well, thereby playing the role of thermal insulation, sound absorption and noise reduction, and safety protection. The glass wool board series has the characteristics of tight and firm material, smooth surface and strong pressure resistance, and the appearance is more crisp and beautiful after installation.
Glass wool can be mainly used in: roof insulation, cold insulation, sound-absorbing materials; building insulation, cold insulation; entertainment venues, theaters, TV stations, radio stations, laboratories, sound-absorbing treatment; air-conditioning pipeline freezing and heat insulation of refrigerated warehouses.
It can be processed into glass wool felt according to actual needs, saving space, reducing costs and avoiding unnecessary waste.
The sound absorption characteristics of centrifugal glass wool are not only related to thickness and bulk density, but also related to factors such as cover material and structural structure. In construction applications, it is also necessary to take into account many aspects such as cost, appearance, fire prevention, moisture resistance, dust resistance, and aging resistance.
In large spaces such as gymnasiums and workshops, in order to absorb and reduce noise, sound-absorbing bodies with centrifugal glass wool as the main sound-absorbing material are often used. Sound-absorbing bodies can be made into plates, columns, cones or other special-shaped bodies according to requirements. , The sound-absorbing body is filled with centrifugal glass wool, and the surface is wrapped with a sound-transmitting surface layer. Since the sound-absorbing body has multiple surfaces for sound absorption, the sound absorption efficiency is very high.
In the road noise barrier, in order to prevent noise reflection, it is necessary to take sound absorption measures on the side facing the vehicle, and centrifugal glass wool is often used as the filling material, and the surface layer is a barrier plate made of perforated metal plate. In order to prevent glass wool from absorbing water and getting damp outdoors, it is sometimes wrapped with PVC or plastic film.

Why is fleece used in fiberglassing.
1. It is a reinforcing material
In the process of GRG production, gypsum slurry and glass fiber are used alternately, layer by layer. The glass fiber helps to strengthen the firmness of the gypsum block and prevent the gypsum from being scattered after solidification.
2. It has high temperature resistance
It has been tested that when the temperature reaches 300°C, it has no effect on the strength of the glass fiber
3. It has high tensile strength
The tensile strength of glass fiber is 6.3~6.9 g/d in standard state and 5.4~5.8 g/d in wet state.
4.It has good electrical insulation
Glass fiber has excellent electrical insulation and is an advanced electrical insulation material. It is also used in heat insulation materials and fire shielding materials.
5. It is not easy to burn
Glass fiber can be melted into glass beads at high temperature, which meets the requirements of fire prevention and control in the construction industry.
6. It has good sound insulation
The combination of glass fiber and gypsum can achieve a good sound insulation effect.
7. It’s cheap
Regardless of the industry, cost control is the most important link, and products with high quality and low price will definitely be favored.
Well, the above are the seven advantages of why glass fiber can be widely used in the construction industry. Glass Fiber is a very good substitute for metal materials.
Fiberglass is an inorganic non-metallic material with excellent performance. It is made of pyrophyllite, quartz sand, limestone, dolomite, boro site, and boro site as raw materials through high-temperature melting, wire drawing, winding, weaving, and other processes. The diameter of the monofilament is several microns to twenty microns, which is equivalent to 1/20-1/5 of a hair, and each bundle of fiber strands is composed of hundreds or even thousands of monofilaments. Fiberglass is usually used as reinforcing materials in composite materials, electrical insulating materials and thermal insulation materials, circuit substrates, and other fields of the national economy.
Here is the content list:
Main features of glass fiber
Melting point: glass is a kind of amorphous, with no fixed melting point, it is generally considered that its softening point is 500~750℃
Boiling point: about 1000 ℃
Density: 2.4~2.76 g/cm3
When fiberglass is used as a reinforcing material for reinforced plastics, the biggest feature is its high tensile strength. The tensile strength is 6.3 to 6.9 g/d in the standard state and 5.4 to 5.8 g/d in the wet state. Good heat resistance, no effect on strength when the temperature reaches 300 ℃. It has excellent electrical insulation, is an advanced electrical insulation material, and is also used for thermal insulation materials and fire shielding materials. Generally only corroded by concentrated alkali, hydrofluoric acid, and concentrated phosphoric acid.
Compared with organic fibers, fiberglass has higher temperature resistance, non-combustibility, corrosion resistance, good heat insulation, and sound insulation, high tensile strength, and good electrical insulation. These characteristics make the use of glass fiber far more extensive than other types of fibers, and the development speed is also far ahead.
(1) High tensile strength and small elongation.

Fiberglass membranes are manufactured from 100% borosilicate glass fibers and include binder-free, chemically inert and binder-containing types. The purpose of adding binder is to enhance the mechanical strength of the glass fiber membrane. It is mainly used to filter coarse particles (such as macromolecular substances, dust). In order to avoid chemical reactions with the filtered substance, glass with inorganic binder is used when filtering organic substances. Fiber membrane, choose glass fiber membrane with organic binder when filtering inorganic substances. This depth filter membrane has the characteristics of fast flow rate, large load capacity and extremely fine retained particles, which can reach the range of submicron particles. The glass fiber membrane can withstand a temperature of 500°C, and can be used for specific gravity analysis and high-temperature gas filtration that require ignition.
