电石质量对PVC生产成本的影响

摘要

通过对不同发气量的电石在PVC生产中的成本计算,表明发气量对PVC生产成本的影响程度很大。随着电石价格的不断攀升,在PVC生产成本中,电石已占75%以上,而电石发气量影响电石消耗,为有效降低PVC生产成本,必须保证电石发气量。%By calculating the PVC production costs,the calcium carbide quality has a great impact on PVC production costs.As the calcium carbide price go up,more than 75% PVC production costs was calcium carbide.The acetylene gas production rate has great impact on calcium carbide consumption.In order to reduce the PVC production costs,it must guarantee the acetylene gas production rate.
