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:
Material properties
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.

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.

Glass fiber is an organic substance, which itself is not harmful to the human body. But fine fiberglass dust is breathed into a person's lungs. Because glass cannot be absorbed and decomposed at all, it will form deposits for a long time, which will cause occupational diseases similar to silicosis. Although the damage is not fatal, it will affect people's respiratory function. Contact dermatitis often occurs in glass fiber workers, and a few people Skin sensitization occurs, but the fibers themselves have not been proven to be allergens so far.
If it's just pure skin contact, there are generally no other problems, the main reason is that it irritates the skin to a certain extent.
The opposite of Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittleness and poor wear resistance.
