Product Description

At room temperature, zinc sulfate heptahydrate is white particles or powder, it is orthorhombic crystal, it has convergence, it is common astringent, it will weathering in dry air. When be heated 30ºC, it can lose a part of crystal water, at 100ºC it loses six crystal water molecules, it loses seven crystal water molecules at 280ºC, it decomposes into zinc oxide and sulfur trioxide at 767ºC. It is soluble in water, slightly soluble in ethanol and glycerol. It requires confined preservation. It is mainly used as raw material for the production of zinc, barium and other zinc saline, it is also important auxiliary raw material for the viscose fiber and vinylon fiber, it can be also used as mordant dyeing, leather and wood preservative, glue clarifying and preserving agents, medical emetic and fungicides, it can be used for trace element fertilizers on agriculture.

 

Production Usage

(1) Zinc sulfate heptahydrate can be used as mordant dyeing, wood preservatives, paper bleaching agent, it can be also used in medicine, synthetic fibers, electrolysis, electroplating, pesticides and production of zinc, etc.

(2) It can be used for the preparation of zinc medicine, astringents, etc.

(3) It can be used as mordant, wood preservatives, bleach paper industry, it is also used in medicine, synthetic fibers, electrolysis, electroplating, pesticides and production of zinc, etc.

(4) Zinc sulfate is zinc supplement of dietary, the component of many enzymes, proteins, such as ribose animals involved in carbohydrate and fat metabolism, and it can catalyze interconversion of pyruvate and lactate, it can promote growth. Zinc deficiency can lead to incomplete keratosis, stunted growth and deterioration of the hair, and it can affect animal reproductive function.

(5) Zinc sulfate is allowed to use in food supplements of zinc. China allows to use it in salt, the used of amount is 500mg /kg; in foods for infants and young children is 113~318mg/kg; in dairy products is 130~250mg/kg; in grains and their products is 80~160rag/kg; in liquid and drink milk drinks is 22.5~44mg/kg.

(6) It is mainly used for man-made fibers coagulating liquid. In printing and dyeing industry, it is used as mordant, salt-stained blue Lamine alkali agent. It is main raw material of manufacturing inorganic pigments (e.g. lithopone), other zinc salts (e.g. zinc stearate, basic zinc carbonate) and zinc-containing catalyst. It is used as wood preservatives and leather, bone glue clarifying and preserving agents. In pharmaceutical industry, it is used as emetic. It can also be used to prevent diseases and fruit tree nurseries and cable manufacturing zinc fertilizer and so on. It can be used as nutritional supplements (zinc enhancer) and the like in food-grade product.

(7) It can be used as analytical reagents, mordant and the phosphor matrix.
