日本最近发明一种制造碳纤维的新方法,具体程序是,把铁或其它金属的超微粒子象播种一样撒在陶瓷基板上,放入电炉里,再向电炉吹进苯的碳化氢气体,加热到1000—2000℃。则气体中的碳以金属粒子为核心生成细长的碳纤维,称为“气相生成碳纤维”这种只须一次加热的“气相生成碳纤维”的方法较之经多次热处理生成碳纤维的聚丙烯腈燃烧法,成本将大大降低。
Japan recently invented a new method of manufacturing carbon fiber, the specific procedure is, the iron or other metal particles sown like sowing on the ceramic substrate, placed in the electric furnace, and then into the electric furnace of benzene gas hydrogen carbide, heated to 1000-2000 ° C. The carbon in the gas generates slender carbon fibers with the metal particles as the core, and the method of “gas-phase-forming carbon fiber” called “gas-phase-forming carbon fiber” which requires only one heating is more effective than the polyacrylonitrile that generates carbon fibers after multiple heat treatments Act, the cost will be greatly reduced.
