Classification and Introduction of Fiberglass

Fiberglass is an inorganic nonmetallic material with excellent properties, which is used to manufacture reinforced plastics or reinforced rubber. It has the advantages of light weight, high strength, high temperature resistance, corrosion resistance, heat insulation, sound absorption and good electrical insulation performance. It is made of pyrophyllite, quartz sand, limestone, dolomite, boralcite and borate brucite by high temperature melting, drawing, winding yarn, weaving and so on. The diameter of its monofilament is from several microns to more than 20 microns, equivalent to 1/20-1/5 of a hair wire.
There are many ways to classify fiberglass:
(1) According to the different raw materials selected at the time of production, fiberglass can be divided into alkali-free, medium-alkali, high-alkali and special fiberglass;
(2) According to the different appearance of the fiber, the fiberglass can be divided into continuous fiberglass, fixed length fiberglass, glass cotton;
On the basis of the difference in the diameter of monofilament, fiberglass can be divided into ultrafine fibers (less than 4 m in diameter), advanced fibers (3~10 m in diameter), intermediate fibers (more than 20 in diameter) and coarse fibers (about 30¨m in diameter).
(4) According to the different properties of fiber, fiberglass can be divided into ordinary glass fiber, strong acid and alkali resistant glass fiber, strong acid resistance
