The reutilization of water, tail gas and carbide slag in PVC production by calcium carbide method, and service condition of super low content mercuric chloride catalyst were introduced.
介绍了电石法聚氯乙烯生产过程中水、尾气和电石渣的循环利用及超低含量氯化汞触媒的使用情况。

Secondly, calciumcarbide easy and moisture from the air after the compounds produced inflammable and explosive gas, this is generally acetylene stave machinery more no problems in.
其次，电石容易与空气中的水分化合后产生易燃易爆的乙炔气体，这是一般破碎机械中更没有遇到的问题。
