    The nanometer zinc oxide and active zinc oxide produced by the Company are a kind of white or yellowish superfine powder with an average granular diameter of 30 nanometers and the scope of the granular diameter at 10~40 nanometers. Compared to the zinc oxide produced with the direct process or the indirect process, they boast such advantages as a large specific surface area and easy dispersion. Zhongle nanometer zinc oxide is produced with the ammonia-ammonium gelatin depositing process, and is mainly used to replace the zinc oxide produced with the direct process or the indirect process, and used as the sulfuration active agents and reinforcing agents for various natural rubber and compound rubber products as well as the colorants and filling agents of white glue, which reduce the consumption by 30-50%. The products can also be widely used for various foaming products, coating additives, feed additives, ceramic glaze, zinc coating raw materials, metal surface treatment phosphorizing liquid, cosmetics, catalysts, porcelain enamel additives, medicine, electronic sensors and anti-static materials, etc.
