Soluble in water, slightly soluble in ethanol and glycerol. Requires airtight storage. It is mainly used as raw materials for the manufacture of zinc barium and other zinc salts, as well as important auxiliary auxiliary raw materials for viscose fiber and vinylon fiber, and also used as dyeing mordant, wood and leather preservatives, bone glue clarification and preservatives, medical emetics and fungicides, and trace element fertilizer in agriculture.
1. Used for the preparation of zinc supplements, astringents, etc.
2. Used as mordant, wood preservative, paper industry bleach, also used in medicine, artificial fiber, electrolysis, electroplating, pesticides and production of zinc salt, etc.
3. Zinc sulfate is a supplement of zinc in feed, which is a component of many enzymes, proteins, ribose, etc., in animals, participating in carbohydrate and fat metabolism, and can catalyze the mutual conversion of pyruvate and lactic acid to promote growth. Zinc deficiency can easily cause hypokeratosis, dysplasia and hair deterioration, and can affect the reproductive function of animals.
4. Zinc sulfate is a permitted food zinc fortification agent. China's regulations can be used for salt, the amount of 500mg/kg; In infant food is 113 ~ 318mg/kg; 130 ~ 250mg/kg in dairy products; 80-160rag /kg in cereals and their products; In liquid and milk beverages, it is 22.5 ~ 44mg/kg.
5. For artificial fiber coagulant. In the printing and dyeing industry, it is used as a mordant and an alkali-resistant agent for valamine blue salt dyeing. It is the main raw material for manufacturing inorganic pigments (such as zinc barium white), other zinc salts (such as zinc stearate, basic zinc carbonate) and zinc-containing catalysts. Used as wood and leather preservative, bone glue clarification and preservative. Used as emetics in the pharmaceutical industry. It can also be used to prevent disease in fruit tree nurseries and to manufacture cables and zinc microfertilizer.
