The source and characteristics of E-glass fiber

May 13,2022

The R2O content of alkali-free glass fiber is less than 0.8%, which is an aluminoborosilicate component. Its chemical stability, electrical insulation properties, and strength are very good. Mainly used as electrical insulating material, reinforcing material of glass fiber reinforced plastic and tire cord. For composite cable holders.

The content of R2O in medium alkali glass fiber is 11.9%-12.4%. It is a sodium calcium silicate component. Because of its high alkali content, it cannot be used as an electrical insulating material, but its chemical stability and strength are still good. Generally used as latex cloth, checkered cloth base material, acid filter cloth, window screen base material, etc. It can also be used as FRP reinforcement material with less strict requirements on electrical properties and strength.

The defects of high alkali glass fiber itself, such as low strength, poor water resistance and alkali resistance, cannot be overcome. Using it as an enhancement product will ultimately only harm the interests of the user.

Glass fiber is an inorganic non-metallic material with excellent properties. English original name: glass fiber or fiberglass. The ingredients are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc. It uses glass balls or waste glass as raw materials through high temperature melting, wire drawing, winding, weaving and other processes. Finally, various products are formed. The diameter of glass fiber monofilament ranges from a few microns to more than 20 microns, which is equivalent to 1/20-1/5 of a hair. It is composed of thousands of monofilaments, and is usually used as a reinforcing material in composite materials, electrical insulating materials and thermal insulation materials, circuit substrates, etc., and is widely used in various fields of the national economy.
