氧化锌主要用于橡胶、塑料、电缆、医药、饲料、涂料、搪瓷等工业,为必加的添加剂。氧化锌产品的纯度、活性对产品质量有直接的影响,我国生产量居世界第四位,生产厂家大都采用锌锭氧化法生产。由于国内锌锭原料严重不足,加之氧化法耗能大,产品成本过高,致使国内缺口达4万吨以上, Zinc oxide is mainly used in rubber, plastic, cable, medicine, feed, paint, enamel and other industries, and is an additive that must be added. The purity and activity of zinc oxide products have a direct impact on product quality. China’s production volume ranks fourth in the world, and most manufacturers use zinc oxide oxidation. Due to the serious shortage of raw materials for zinc ingots in the country, coupled with the large energy consumption of the oxidation process and high product costs, the domestic gap reached more than 40,000 tons.
