Zinc salt grade zinc oxide powder is widely used in the production of organic and inorganic zinc salts such as zinc stearate, zinc bromide, zinc borate, and phosphating solution.

Zinc Salt Grade Zinc Oxide powder

1. Zinc stearate produced from zinc salt grade zinc oxide powder is white powder and insoluble in water. Mainly used as a lubricant and release agent for styrene resin, phenolic resin and amino resin. At the same time, it also has the functions of vulcanization activator and softener in rubber. Zinc stearate produced by zinc salt-grade zinc oxide powder is made by melting method, also known as dry method, which means that zinc oxide is directly added to molten stearic acid. In the presence of a catalyst, a certain temperature, pressure and Stirring speed, stearate is obtained through reaction.

2. Zinc bromide made from zinc salt grade zinc oxide powder is a white diamond-shaped crystalline powder. Easily soluble in water, alcohol, acetone and tetrahydrofuran. Dissolved in ammonia water. Insoluble in ether. It is produced by the reaction of zinc oxide and hydrobromic acid, used as a post-treatment agent for rayon, and can also be used in pharmaceuticals and photography.

3. Zinc borate made of zinc salt grade zinc oxide powder is an environmentally friendly non-halogen flame retardant. It has the characteristics of non-toxic, low water solubility, high thermal stability, small particle size, small specific gravity, and good dispersibility. It is a highly efficient Flame retardants are widely used in plastics, rubber, coatings and other fields.

4. The main component of the phosphating solution made of zinc salt grade zinc oxide powder is dihydrogen phosphate, such as Zn(H2PO4)2 and appropriate amount of free phosphoric acid and accelerators. In principle, once a metal workpiece is immersed in a heated dilute phosphoric acid solution, a film will be formed. However, due to the poor protection of this kind of film, the usual phosphating is carried out in an acidic solution containing Zn, Mn, etc.

MST zinc salt grade zinc oxide powder has high purity, low impurities and good stability. It is a high-quality additive for the production of organic and inorganic zinc salts.
