玄武岩纤维是将破碎的玄武岩矿石在矿炉中加热到1450℃～1500℃熔融后,通过铂铑合金漏板拉成粗纤维,再经过近一步的缠绕机拉制成需要的规格纤维。玄武岩纤维的主要化学成分为:SiO2、Al2O3、CaO、MgO和Fe2O3、FeO、TiO2、K2O、Na2O及少量杂质。玄武岩的不同组分赋予了纤维特定的性能,如:
Basalt fiber is crushed basalt ore in the furnace heated to 1450 ℃ ~ 1500 ℃ after melting, through the platinum rhodium alloy drawing board crude fiber, and then through the next step of winding machine drawn into the required specifications of the fiber. Basalt fiber main chemical composition: SiO2, Al2O3, CaO, MgO and Fe2O3, FeO, TiO2, K2O, Na2O and a small amount of impurities. The different components of basalt give fiber-specific properties such as:
