500 Mesh Zn Zinc Metal Powder For Chemical Production
Factory Price High Purity Zn Powder Zinc Metal Powder for Chemical Production
Main Characteristics:
Nano-zinc powder, ultra-fine zinc powder prepared through a special process, the high activity of zinc powder has a high content of zinc and other impurity elements on the particle surface smooth, large surface area and average particle size controlled, bulk density surface oxidation, melt deformation and adhesion to a little grape-like particles, easily dispersed and industrial applications.
Usage:
Mainly used as key raw material in zinc-rich coating,as well as in anti-corrosion, environment protection and other high performance coating. They can be widely applied in large steel structures, ship building, container industries aviation, automobile; also widely applied in chemical industry,Mechanical Galvanizing,Metallurgy and Medicine Area.Storage:Stored in dry, airy warehouse without acid, alkali and inflammables.
Be cautious of moisture, water and fire during storing and transportation.

Applications:
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 so on, which are not suitable for hot plating and electroplating.
