Secondly, calcium carbide 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。

The raw material is dry acetylene technology of artificial synthesis, and calcium carbide contains certain metal components, this is generally not appear stave machinery.

干法乙炔工艺中的原料是人工合成的电石，而且电石中含有一定的金属成分，这是一般破碎机械中没有出现的问题。
