1·Calcium carbide, widely applied in synthesis of organic chemical products, such as benzene, rubber, polyvinyl chloride, and polyacetylene, is a main intermediate product of clean coal utilization.
电石作为煤炭清洁化的一个主要中间产品，广泛应用于合成苯、橡胶、聚氯乙烯、聚乙炔等有机化工产品。
2·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。
3·Some new process, new units and new materials used broadly in domestic production enterprises of calcium carbide PVC were introduced.
介绍了国内电石法pvc生产企业近年来广泛采用的一些新工艺、新设备和新材料。
4·The new technology and new process instead of traditional technology and equipment in PVC production by calcium carbide method were introduced.
介绍了在电石法PVC生产中利用新技术与新工艺改造传统技术和设备的情况。
5·Acetylene is manufactured by the reaction of water with calcium carbide. It is also manufactured by thermal cracking of hydrocarbons, or by partial combustion of methane with oxygen.
通过水同电石的反应生产乙炔。还可以通过碳氢化合物的热裂解或甲烷同氧的不完全燃烧来生产乙炔。
