Product Description
Basalt fiberThe development of basalt fiber began in the Soviet Union in the 1960s. At that time, basalt fiber exceeded glass fiber in some characteristics, its strength was higher than steel, and its high strength retention rate at high temperature of 700 º C attracted the attention of the Soviet . After more than 20 years of continuous practice, Soviet scientists finally developed the production process and technology of basalt continuous fiber.Continuous basalt fiber (CBF) is a new type of inorganic fiber material with high performance. It is a continuous fiber made of volcanic rock (a variety of basalt, natural basalt stone mainly composed of oxides such as silica, alumina, calcium oxide, iron oxide and titanium dioxide) as raw materials, melted at 1450 ºC ~ 1500 ºC and pulled at high speed through platinum rhodium alloy wire drawing leakage plate. Because the fiber color is golden brown, it is also known as "golden fiber". Continuous basalt fiber has the advantages of good stability, good electrical insulation, corrosion resistance, flame retardant, high temperature resistance and low temperature resistance. It has excellent comprehensive performance, low raw material cost, natural environmental protection and high cost performance. Basalt fiber is a pure natural inorganic non-metallic material, which can be degraded into soil parent material and absorbed by soil. It is a green environmental protection product. Performance characteristics of basalt fiber:1. Outstanding temperature resistance. The service temperature range of CBF is: - 260 ~ 900 ºC (softening point is 960 ºC). 2. Outstanding tensile strength: the tensile strength of CBF is 3800 ~ 4800 MPa. 3. Natural compatibility with silicate. It belongs to silicate like cement and has stable performance in alkaline medium.4. Outstanding chemical stability, excellent acid and alkali corrosion resistance and water resistance. 5. Significant thermal vibration stability. The mass loss fraction of CBF at 900 ºC is only 0.03. 6. Good dielectric properties. The volume resistivity is one order of magnitude higher than that of glass fiber, and the dielectric loss tangent is 50% lower than that of glass fiber. 7. Excellent wave transmission performance and certain wave absorption performance.8. It has good radiation protection function.9. Flame retardancy: in case of open fire, it will not burn.Comparison between basalt fiber and other fibers| Performance | Basalt fiber | E glass fiber | Aramid fiber | carbon fibre |
