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.

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.
Fiberglass is a glass material similar to the glass in our windows or the glasses we use to drink our favorite beverages. In modern life, the application of glass fiber can be seen everywhere. People know it differently. The best thing about fiberglass is that it is durable, unbreakable, very strong, and lightweight.
Here is the content list:
Production of glass fibers
Application of glass fiber
Sound-absorbing applications of fiberglass
From the manufacture of glass fibers, the glass is heated until it begins to melt and melt. It is then further forced through the ultrafine pores. This gives us very fine glass filaments, down to the point of being measured in microns. This is the basis of how fiberglass can serve such a variety of uses. These filament threads are flexible and can be molded into a variety of complex shapes for many different applications.
Fiberglass becomes a widely used material in all industries. In addition to being an excellent insulating material, fiberglass is also very cost-effective.
In our daily life, FRP products are used everywhere: subway bodies, auto parts, medical devices, ships, furniture, structural parts for construction and industrial projects, FRP pipes, etc. Why are the surfaces of these FRP products so flat and smooth? The use of fiberglass as the skin material for these products is a key reason.
Fiberglass panels are used in building and decorative acoustic panels. After being coated with calcium powder, it is used as the surface layer of thermal insulation materials such as PU and rock wool boards. Fiberglass board has the advantages of being fireproof, waterproof, and mildew proof, smooth surface, uniform fiber dispersion, good weather resistance, and long service life. It is an ideal acoustic decorative material for residents and public areas.
Fiberglass panels are produced with unrivaled formulations and processes, and the thickness of fiberglass panels can reach 8mm to 10mm, and a layer of porous structure gives fiberglass panels a unique combination of sound absorption. At the same time, glass fiberboard has the characteristics of heat preservation, heat preservation, and fire prevention. Coupled with the excellent properties of stiffness, lightweight, bendability, and ease of cutting, further processing, and installation of fiberglass panels are very easy and simple.
