Basic properties: molecular formula: Zn, molecular weight: 65.38

Physical properties: dark gray metal fine powder

Density : 7.14g/cm³, melting point: 419.4°C, boiling point: 908°C

Chemical properties: insoluble in water, soluble in acid and alkali, slowly soluble in acetic acid, ammonia. It has strong reducing property and emits hydrogen with acid and alkali. Moistened by moisture, stable in dry air, and white basic carbonate formed in moist air to cover the surface. The air burns a blue-green flame to produce zinc oxide. High purity reacts slowly with sulfuric acid and nitric acid, and accelerates when a small amount of other metals such as steel, tin, and lead are contained.

Product uses: organic, inorganic chemicals, pharmaceuticals, pesticides, printing and dyeing, metallurgy, reducing agents, catalysts and other industries.

Mechanical plating and diffusion coating Zinc production: mainly used for mechanical galvanizing of screws, nails, iron wire, nails, etc., our company produces refined zinc powder for mechanical galvanizing process production, air flow wind speed multi-level particle size from The combination mechanism of 300-1500 aims is suitable for the mechanical galvanizing production process required by different levels of technical standards, and the plating layer is smooth. In addition, the special zinc powder produced by our company which is suitable for the technical requirements of diffusion coating process has the characteristics of uniform particle size distribution and is not easy to be oxidized during use.

Mainly used as a key raw material for wet smelting and zinc-rich anticorrosive coatings, it is widely used in large steel components (such as large outdoor steel structures, marine engineering, bridges, pipelines, etc.) and ships, containers, etc., which are not suitable for hot spots and electroplating.
