Product Description

Zinc sulfate Heptahydrate is an inorganic compound with the molecular formula ZnSO4·7H2O, commonly known as alum and zinc alum. Colorless orthorhombic prismatic crystal, white crystalline powder, soluble in water and slightly soluble in ethanol. It loses water when heated to 200°C and decomposes when heated to 770°C.
Zinc sulfate heptahydrate is harmful if swallowed. It can cause serious damage to the eyes and is extremely toxic to aquatic organisms. It may have long-term adverse effects on the water environment. Zinc sulfate heptahydrate can be used as a mordant, wood preservative, and bleaching agent in the papermaking industry. It is also used in medicine, man-made fibers, electrolysis, electroplating, pesticides, and the production of zinc salts.

1. Used to prepare zinc supplements, astringent drugs, etc.
2. Used as mordant, wood preservative, bleaching agent in paper industry, also used in medicine, man-made fiber, electrolysis, electroplating, pesticide and production of zinc salt, etc.
3. Zinc sulfate is a zinc supplement in feed. It is a component of many enzymes, proteins, ribose, etc. in animals. It participates in carbohydrate and fat metabolism, and can catalyze the mutual conversion of pyruvate and lactic acid to promote growth. Insufficient zinc can easily cause parakeratosis, stunted development and hair deterioration, and can affect the reproductive function of animals. use
4. Zinc sulfate is a permitted food zinc fortifier. Our country stipulates that it can be used for table salt, and the usage amount is 500mg/kg; in infant food, it is 113~318mg/kg; in dairy products, it is 130~250mg/kg; in cereals and their products, it is 80~160mg/kg; in In drinking liquids and milk drinks, it is 22.5 to 44 mg/kg.
5. Used in artificial fiber coagulation liquid. In the printing and dyeing industry, it is used as a mordant and an anti-alkali agent for varamine 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 in the pharmaceutical industry as an emetic. It can also be used to prevent diseases in fruit tree nurseries and make cables and zinc micro-fertilizers.
