Specification

1. It is mainly used as the key raw material of zinc-rich anticorrosive coatings and widely used in the coating of large steel structures (such as steel structure buildings, marine engineering facilities, bridges, pipelines), ships, containers and soon, which are not suitable for hot plating and electroplating.

2. Zinc powder products are increasingly used for galvanizing and corrosion protection of relatively small prefabricated steel components, bolts, screws, nails and other steel products.3. Zinc powder products are used in the production of pharmaceutical and pesticide intermediates in the pharmaceutical and pesticide industries, mainly playing the role of catalysis in the synthesis of organic compounds and the formation of hydrogen bonds.4. Zinc powder products are widely used in the metallurgical process of zinc, gold, silver, indium, platinum and other non-ferrous metal products, which play the role of reduction and replacement, impurity removal and purification in the metallurgical process.5. Zinc powder products are widely used in the production process of chemical products, such as rongalite, dye intermediates, plastic additives, sodium hydrosulfite, lithopone and so on, which play the role of catalysis, reduction and hydrogen ion generation in the production process.
