Zinc sulfate

Zinc sulfate, zinc sulfate, ZnSO4 — zinc salt of sulfuric acid.

Colorless crystals, density 3,74 g/cm3. Solubility in water (%): 29,4 (0 °C) OF 37.7 (99 °C). From solutions at temperatures below 38,8 °C kristallizuetsya ZnSO4·7H2O (zinc sulfate), ranging from 38,8 °C to 70 °C — ZnSO4·6H2O, above 70 °C formed the monohydrate ZnSO4·H2O. The latter is dehydrated at 238 °C. the zinc Sulfate in the range of 600-900 °C is decomposed into ZnO and SO3. Weak solutions of zinc sulfate in the hydrolysis turbid due to the discharge of sediment 3Zn(OH)2·ZnSO4·4H2O.

Zinc sulphate is obtained by evaporation and crystallization from solutions (simultaneously with the production of zinc).

Zinc sulfate is widely used in electroplating, and in the production of artificial fibers. In chemical industry it is applied in the production of viscose, glazes, and good to protect the wood from rotting, necessary and in metallurgy.

It is also used as mordants in the textile industry, and in as bleach in pulp and paper production.

Pharmaceuticals used in antifogmatic creams, cleansers for the face means for washing the gel.

In medicine from zinc sulfate eye drops made, dentistry also actively applies this chemical element. Sulphate of zinc has astringent, antiseptic, a drying, immunomodulatory effects on the body person. Indications for topical use - laryngitis, conjunctivitis, vaginitis, urethritis.

Zinc sulfate is a universal fertilizer used in the deficit zinc in the soil, which is used for fruit, vegetable, berry and flower cultures. Designed for foliar feeding crops during the growing season, zinc content of 18-22%. Use of zinc sulfate allows to reduce the time of fruit ripening, improve productivity and increase the content of sugars and vitamins in fruit.

Particularly effective at fertilizing fruit crops and tomatoes and potatoes.

Laboratory practice is yet another aspect of the use of zinc sulfate.

This material is fire and explosion proof, toxins in the air do not form, to influence the person belongs to the 2nd class of hazard. Has the ability to enter the body through the respiratory tract, gastrointestinal tract and holistic skin. On the skin in contact with them ulcers, mucous erosions. In to avoid this, facilities that use zinc sulfate, you need a good ventilate. You must use PPE. The permitted concentration of a substance in working airspace – 0.5 mg/m3.

Zinc sulphate is Packed in special containers or five-layer paper bags. Allowed to be Packed in soft containers one-time use. For the feed industry product is Packed in double bags (inner plastic, outer - double-wall paper.

Transporterowych all types of transport in covered vehicles in accordance with the rules of goods carriage, valid for this type transport. Rail zinc sulfate is transported carload shipments.

Zinc sulfate is stored in bags in covered warehouses, in containers - open sites.
