在我国,电石产品70%用于生产PVC,随着旨在控制和减少全球汞使用与排放的《水俣公约》的签订,电石法PVC的前景令人担忧,在产业链上与其唇齿相连的电石的角色似乎更为尴尬。业内人士甚至坦言,作为“两高一资”的电石行业,后期将长期颓势。限汞逼迫企业压缩用量根据10月10日在日本熊本市表决通过的《水俣公约》,中国2020年单位聚氯乙烯用汞量要比2010年减少50%,2028年要全面禁止使用含汞触媒。
In China, 70% of calcium carbide products are used in the production of PVC.

In the industrial chain, calcium carbide linked to its lips and teeth The role seems more embarrassing. The industry even admitted that as the “two high and one capital” of the calcium carbide industry, the latter part of the long-term decline. Limitation of Mercury forcing Enterprises to Decrease Consumption According to the Minamata Pact adopted on 10 October in Kumamoto, Japan, the mercury content of PVC in China in 2020 will be 50% less than in 2010 and the total ban on the use of mercury-containing catalysts by 2028 .
