98% Neutralization of Chemical Processing Additives Catalyst Zinc Sulfate Heptahydrate 7446-20-0 Zinc Sulfate Heptahydrate

summarize

At normal temperature zinc sulfate heptahydrate is white particle or powder, orthogonal crystal, convergence, is a commonly used astringent, will be weathered in dry air. When heated to 30 ° C, one molecule of crystal water is lost, six molecules of crystal water are lost at 100 ° C, seven molecules of crystal water are lost at 280 ° C, and zinc oxide and sulfur trioxide are decomposed at 767 ° C. Soluble Chemicalbook 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 raw materials for viscose fiber and vinylon fiber, and also used as dyeing mordant, wood and leather preservation agent, bone glue clarification and preservation agent, medical emetics and fungicides, and trace element fertilizer in agriculture.

use

Used as mordant, wood preservative, paper industry bleach, also used in medicine, artificial fiber, electrolysis, electroplating, pesticides and production of zinc salt. Zinc sulfate is a supplement of zinc in feed, which is a component of many enzymes, proteins, ribose and so on 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. 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 Chemicalbook dairy products; 80-160rag /kg in cereals and their products; In liquid and milk beverages, it is 22.5 ~ 44mg/kg. Determination of copper and chlorate by reagent drop analysis. Serum protein test, determination of sulfur content in steel and slag. Various media were prepared in coal stain, disinfectant and haploid breeding. In plant cell culture, as a zinc source to support cell membrane stability and gene regulation. Used as coagulant for artificial fibers. 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. Chemicalbook is 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. Food grade products can be used as nutritional supplements (zinc enhancers), etc.
