电石,是生产聚乙烯塑料、碳黑、氯丁橡胶等产品的重要化工原料。尤其是用来生产聚乙烯塑料所做成的管、板、丝、膜,在国民经济各部门有着广泛的用途。目前,在我国,电石在化学工业的消耗系数在0.6以上,而其中80%左右主要是用于聚乙烯塑料的生产。因此,电石需求量在很大程度上受塑料工业发展的影响。而电石作为高耗能 Calcium carbide, is the production of polyethylene plastics, carbon black, neoprene and other products of important chemical raw materials. Especially for the production of polyethylene plastic pipes, plates, silk, film, in all sectors of the national economy has a wide range of uses. At present, in China, the consumption coefficient of calcium carbide in the chemical industry is above 0.6, of which about 80% is mainly used for the production of polyethylene plastic. Therefore, the demand for calcium carbide is largely affected by the development of the plastics industry. The calcium carbide as a high energy consumption
