The long-term demand of glass fiber industry is good, and the prosperity of the industry continues

1. Glass fiber is a sunrise industry in the world with good performance and wide application

Glass fiber is a new inorganic nonmetal material with superior performance, and it is also the most widely used composite material in modern industry. At present, glass fiber, carbon fiber and aramid fiber are the main reinforcing materials used in the global composite industry, of which glass fiber accounts for 98.80% of the total amount. The typical characteristics of glass fiber are: high specific strength, light weight, high modulus of elasticity, low elongation, good electrical insulation, corrosion resistance, high temperature resistance, low moisture absorption, etc. As a new type of material, glass fiber is usually used as the reinforcing material in composite materials. Compared with traditional materials, glass fiber reinforced materials are cheaper, lighter, better, more energy-saving and environmental protection.

Glass fiber can be divided into alkali free glass fiber, medium alkali glass fiber, high alkali glass fiber and so on. The content of R2O in alkali free fiber (E-glass) is less than 0.8%, which is a kind of aluminoborosilicate. It has good chemical stability, electrical insulation and strength. It is mainly used as electrical insulation material, FRP reinforcement material and tire cord; The content of R2O in medium alkali fiber is 11.9% - 16.4%. It is a kind of sodium calcium silicate. Because of its high alkali content, it can not be used as electrical insulation material, but its chemical stability and strength are still good. Generally, it can be used as base material of latex cloth, checkerboard cloth, acid filter cloth, window screen, etc. it can also be used as reinforced material of glass fiber reinforced plastics with less strict requirements on electrical properties and strength. This kind of fiber has low cost and wide application.

Glass fiber products are mainly divided into non-woven products and textile products. Non woven products refer to the products made of glass fiber by non-woven means (mechanical, chemical or thermal), mainly including glass fiber felt (such as chopped felt, continuous felt, needle punched felt, etc.) and ground fiber.

As a basic material, glass fiber has a high degree of correlation with downstream production. After deep processing, glass fiber is widely used, such as building materials, transportation, electronic appliances, environmental protection and wind power. At present, there are more than 5000 varieties and 60000 specifications of glass fiber, and the categories and specifications are still growing at a fast speed, with a speed of nearly 1000 / year to 1500 / year.
