Features introduced

Raw material and application: glass fiber is better than organic fiber in temperature resistance, non-combustion, corrosion resistance, heat insulation, sound insulation, high tensile strength, good electrical insulation. But brittle, wear resistance is poor. Used to manufacture reinforced plastic (see color picture) or reinforced rubber, as a reinforcement material glass fiber has the following characteristics, these characteristics make the use of glass fiber is far more extensive than other types of fiber, the development rate is far ahead of its characteristics listed as follows:

(1) High tensile strength, small elongation (3%). Glass fiber cutting

(2) High elastic coefficient, good rigidity.

(3) Within the elastic limit, the elongation is large and the tensile strength is high, so the impact energy is absorbed.

(4) Inorganic fiber, non combustible, good chemical resistance.

(5) small water absorption.

(6) Good scale stability and heat resistance.

(7) Good processability, can be made into strands, bundles, felt, woven fabrics and other different forms of products.

(8) Transparency through light.

(9) Completion of the development of surface treatment agents with good adhesion to resins.

(10) Low price.

(11) not easy to burn, high temperature can be fused into glass beads.

Main ingredients

Its main components are silicon dioxide, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc., according to the amount of alkali content in the glass, can be divided into alkali free glass fiber (sodium oxide 0% ~ 2%, Aluminum-borosilicate glass), medium alkali glass fiber (sodium oxide 8% ~ 12%, sodium calcium silicate glass with or without boron) and high alkali glass fiber (sodium oxide more than 13%, sodium calcium silicate glass).
