Brief introduction to the uses of zinc powder

2017-03-08

Mainly used in paint, coating, galvanizing, smelting, pharmaceutical intermediates, electroplating, reduction and other industries. 1. Chemical production is used in the production of zinc dust, lithopone, blanc fixe, fuel intermediates, etc., as a reducing agent, with a large dosage and coarser particle size than coating zinc powder. 2. Zinc anti-corrosion coating production The corrosion protection of steel components is the most important use of metallic zinc. Coating methods include hot-dip galvanizing, electroplating, thermal spraying, zinc-rich coatings, powder coating, etc., among which hot-dip galvanizing is the main method. Zinc-rich coatings are mainly used for large components that are not suitable for hot-dip galvanizing and electroplating, such as large outdoor steel structures, ships, containers, etc. 3. Fine zinc powder except

1. Chemical production Used in the production of zinc hydrosulfite, lithopone, blanc fixe, fuel intermediates, etc., as a reducing agent, with a large dosage and coarser particle size than zinc powder for coatings.

 

2. Zinc anti-corrosion coating production Corrosion protection of steel components is the most important use of metallic zinc. Coating methods include hot-dip galvanizing, electroplating, thermal spraying, zinc-rich coatings, powder coating, etc., with hot-dip galvanizing being the most common method. Zinc-rich coatings are mainly used for large components unsuitable for hot-dip galvanizing and electroplating, such as large outdoor steel structures, ships, and containers.

 

3. In addition to zinc-rich coatings, fine-grained zinc powder is also used in thermal spraying, powder coating, and other aspects, coating the steel surface to provide corrosion protection.
