Zinc sulfate heptahydrate (Zinc sulfate Heptahydrate) is an inorganic compound with the molecular formula ZnSO4-7H2O, commonly known as alum, zinc alum. Colorless rhombohedral prismatic crystals, white crystalline powder, soluble in water, slightly soluble in ethanol. Loss of water when heated to 200°C, decomposed at 770°C. Zinc sulfate heptahydrate is harmful if swallowed.
Zinc sulfate heptahydrate is harmful if swallowed, causes serious eye damage, is highly toxic to aquatic organisms, and may cause long-term adverse effects on the aquatic environment. Zinc sulfate heptahydrate can be used as mordant, wood preservative, paper industry bleaching agent, but also used in medicine, synthetic fiber, electrolysis, electroplating, pesticides and the production of zinc salts.
Uses
1. Used in the preparation of zinc tonic, astringent, etc.
2. Used as mordant, wood preservative, paper industry bleaching agent, also used in medicine, man-made fibers, electrolysis, electroplating, pesticides and the production of zinc salts, etc.
3. Zinc sulfate is a zinc supplement in the feed, is a component of many enzymes, proteins, ribose, etc. in the animal body, involved in carbohydrate and fat metabolism, and can catalyze the mutual conversion of pyruvate and lactate, to promote growth. Insufficient zinc can easily cause incomplete keratosis, stunted development and hair deterioration, and can affect the reproductive function of animals. Uses
4. Zinc sulfate is a permitted zinc fortifier for food. Our country stipulates that it can be used in table salt, and the usage amount is 500mg/kg; in baby food, it is 113-318mg/kg; in dairy products, it is 130-250mg/kg; in cereals and their products, it is 80-160rag/kg; in drinking liquid and milk beverage, it is 22.5-44mg/kg.
5. Used in man-made fiber solidifying liquid. It is used as mordant in printing and dyeing industry, and antialkali agent for dyeing of vanadium blue salt. It is the main raw material for the manufacture of inorganic pigments (such as zinc barium white), other zinc salts (such as zinc stearate, alkaline zinc carbonate) and zinc-containing catalysts. Used as wood and leather preservative, bone glue clarifying and preserving agent. Used as an emetic in the pharmaceutical industry. It is also used to prevent diseases in fruit tree nurseries and in the manufacture of cables and zinc micronutrient fertilizers
