Characteristics and application scope of basalt fiber

Basalt fiberraw material is natural basalt, basalt crushed and added to the kiln, in 1400 ~ 1500 ℃ melting, through the stretching of fibers, and the fiber as a reinforcing system into a new type of Composite Materials.
Compared with Glass Fiber, mineral wool fiber and other fiber materials, basalt fiber has the following advantages.
1. Good tensile strength and reinforcing effect;
2. High corrosion resistance and chemical stability;
3. Good insulation;
Basalt fiber dielectric loss angle tangent and glass fiber is similar, with special infiltration agent treated basalt fiber, its dielectric loss angle tangent than the general glass fiber is also lower than 50%, can be used in the manufacture of high-voltage (up to 250KV) electrical insulating materials, low-voltage (500V) devices, antenna fairings and radar radio devices, etc., the prospects are very broad, the special infiltration agent treatment of basalt fiber can also be used for the manufacture of new heat-resistant dielectric materials. Manufacture of new heat-resistant dielectric materials.
Basalt fiber is the repair of roads, railroads, airports runways used in the best material in the stone, with strong compression resistance, low crushing value, corrosion resistance, asphalt adhesion basalt, basalt has wear-resistant, low water-draught, poor electrical conductivity, strong compression resistance, low crushing value, corrosion resistance, asphalt adhesion, etc., and is internationally recognized as the development of rail transport and road transport is the best cornerstone.
