Industry:
It is the main raw material for the manufacture of lithopone and zinc salt. It can also be used as a mordant for printing and dyeing, as a preservative for wood and leather. It is also an important auxiliary raw material for the production of viscose fiber and vinylon fiber. In addition, it is also used in electroplating and electrolysis industries, and can also be used to make cables.
Cooling water in industry is the largest consumption of water. The cooling water in the closed circulating cooling system must not corrode and scale the metal, so it needs to be treated. This process is called water quality stabilization, and zinc sulfate is used as a water quality stabilizer here.
Medicine:
Oral zinc sulfate can correct zinc deficiency and restore the function of the enzyme system. Zinc ions can precipitate proteins, have astringent and antiseptic effects for external use, and can help the formation of granulation tissue. Medicinal zinc sulfate is suitable for the treatment of enteropathic acrodermatitis, aphtha, chronic ulcer, conjunctivitis, etc. caused by zinc deficiency. But sharing with penicillamine can weaken the effect of the latter. Zinc sulfate monohydrate can be used as a zinc supplement in feed.
Agriculture:
It can be used to prevent diseases in fruit tree nurseries. It is also a commonly used fertilizer to supplement crop zinc trace element fertilizers. It can be used as base fertilizer, foliar fertilizer, etc. Zinc is one of the essential nutrient elements for plants. White flower seedlings are prone to appear due to zinc deficiency in maize. When severe zinc deficiency occurs, the growth will stop or even the seedlings will die. Especially for some sandy loam soils or fields with high pH values, zinc sulphate and other zinc fertilizers should be added. The application of zinc fertilizer also has the effect of increasing yield. Fertilization method: take 0.04~0.06 kg of zinc fertilizer, add 1 kg of water, dress 10 kg of seeds, and pile up for 2~3 hours to sow. Before sowing, apply zinc fertilizer to the rhizosphere layer, 0.75 to 1 kg per mu. If the leaf color is light in the seedling stage, zinc fertilizer can be sprayed at a rate of 0.1 kg per mu.
