In dustrially, zinc sulfate is a primary raw material for manufacturing zinc barium white and zinc salts. It is also used as a mordant in dyeing and printing, a preservative for wood and leather, and an important auxiliary material in the production of viscose and vinylon fibers. Additionally, it has applications in electroplating and electrolysis industries, and can be used in cable manufacturing.
In industry, cooling water constitutes the largest volume of water used. In closed-loop cooling systems, the cooling water must not corrode metals or cause scaling; therefore, it must be treated. This process is called water stabilization, and zinc sulfate is used as a water stabilizing agent in this process.
In pharmaceutical applications, oral zinc sulfate can correct zinc deficiency and restore the function of enzyme systems. Zinc ions can precipitate proteins, and when applied externally, it has astringent and antiseptic effects, and can also help granulation tissue formation. Pharmaceutical zinc sulfate is suitable for treating enteropathic acrodermatitis, oral ulcers, chronic ulcers, conjunctivitis, etc., caused by zinc deficiency. However, its effect can be weakened when used with penicillamine. Zinc sulfate monohydrate can be used as a zinc supplement in animal feed.
In agriculture, zinc fertilizer can be used to prevent diseases in fruit tree nurseries and is also a commonly used fertilizer to supplement crops with zinc micronutrients. It can be used as a base fertilizer or foliar fertilizer. Zinc is one of the essential nutrients for plants. Zinc deficiency in corn easily leads to white-flowered seedlings, and severe zinc deficiency can cause growth to stop or even seedling death. Especially for sandy loam soils or fields with excessively high pH values, zinc fertilizers such as zinc sulfate should be applied. Applying zinc fertilizer can also increase yield. Fertilization method: Take 0.04-0.06 kg of zinc fertilizer, mix it with 1 kg of water, mix it with 10 kg of seeds, and pile it up for 2-3 hours before sowing. Before sowing, apply zinc fertilizer to the root zone at a rate of 0.75-1 kg per acre. If the leaves are pale during the seedling stage, zinc fertilizer can be sprayed at a rate of 0.1 kg per acre.
