Read： 606 Time：11months ago Source：Transform the World with Simplicity

Zinc sulfate is an important raw material for chemical production, which has a wide range of properties and uses. This article will detail the properties of zinc sulfate, production methods and applications in different fields.

1. the nature of zinc sulfate

zinc sulfate is a colorless or white crystalline powder, odorless, taste astringent. It is stable in the air, but loses crystal water at high temperatures and becomes anhydrous zinc sulfate. Zinc sulfate is soluble in water, and the aqueous solution is acidic. In addition, it also has good electrochemical properties and can be used as one of the components of the electrolyte.

2. zinc sulfate production methods

zinc sulfate production methods are mainly the following:

1. Wet production: zinc ore or zinc oxide reaction with dilute sulfuric acid, through filtration, evaporation, crystallization and other processes to produce zinc sulfate.
2. pyrogenic production: zinc ore and coke are reacted at high temperature to generate zinc vapor, which is then absorbed by dilute sulfuric acid to produce zinc sulfate.

3. the use of zinc sulfate

zinc sulfate in the field of chemical production raw materials has a wide range of uses, the following list of several main aspects:

1. electroplating industry: zinc sulfate can be used as the main component of electroplating solution, used for galvanized or other metal surface treatment, in order to improve its corrosion resistance and appearance quality.
2. Fertilizer industry: zinc sulfate contains zinc, which can be used as a trace element fertilizer to promote the growth and development of crops.
3. pharmaceutical industry: zinc sulfate has a certain convergence and bactericidal effect, can be used for the treatment of skin ulcers, eczema and other diseases. At the same time, it can also be used as raw materials or excipients for certain drugs.
4. Animal husbandry: Zinc sulfate can be used as a feed additive for livestock and poultry to promote their growth and development and improve disease resistance.

In short, zinc sulfate has a wide range of properties and uses in the field of chemical production raw materials, which is of great significance for promoting industrial production, improving product quality and promoting economic development.
