Glass fiber is a high-strength, lightweight special fiber made of glass as raw material, melted at high temperature, and then manufactured by spinning molding process. It is widely used in construction, transportation, electricity, environmental protection, chemical industry, agriculture and other fields. According to different production processes and application requirements, the existing glass fibers are mainly divided into the following five varieties.
2. Variety classification
1. E-type glass fiber
E-type glass fiber is the earliest developed glass fiber. It is characterized by good corrosion resistance and stable composite performance in composite materials. It is mainly used to manufacture fiberglass, building materials, electronic appliances and other products.
2. S-type glass fiber
S-type glass fiber is an improved product of E-type glass fiber. Its main characteristics are high strength, strong corrosion resistance and good thermal stability. It is usually used in subways, ships, composite materials and other fields.
3. C-type glass fiber
C-type glass fiber is a special glass fiber made of silicate glass as raw material and a special mixture of metal oxides such as alumina and zirconium oxide. It is characterized by high strength, high stiffness, small thermal expansion coefficient and good corrosion resistance. It is mainly used in composite materials under high temperature environment.
4. AR glass fiber
AR glass fiber is made by adding special ingredients such as aluminate to E glass fiber. It is characterized by good alkali resistance and corrosion resistance, and is usually used in construction, chemical industry, environmental protection and other fields.
5. ECR glass fiber
ECR glass fiber refers to glass fiber made from metal ions such as sodium and potassium in electrolyzed water as glass fiber raw materials. It is characterized by high strength and modulus, small thermal expansion coefficient, and strong corrosion resistance. It is usually used in high-end ships, aerospace and other fields.
Conclusion
The above is an introduction to the classification of glass fiber varieties. Various glass fibers are complementary and compatible with each other. Therefore, in practical applications, different varieties of glass fibers can be selected and manufactured according to the specific performance required to meet the needs of various industries.
