Zinc sulphate powder is well soluble in water, the aqueous solution is slightly acidic, soluble in glycerin, slightly soluble in ethanol, and forms ZnSO4·K2SO4·6H2O type double salt with potassium sulfate. Metal zinc or zinc oxide is dissolved in dilute sulfuric acid, concentrated and crystallized at 30°C to obtain zinc sulfate heptahydrate, and then the temperature is raised to obtain various other Zinc sulphate powders.

Product function:

  • industry
    • Zinc sulphate powder is the main raw material for the manufacture of lysophone and zinc salt, it is also used as a mordant in printing and dyeing, and can also be used as a preservative for wood and leather. Viscose and vinylon fibers. It is also used in the electroplating and electrolysis industries and can also be used to make cables.
    • Industrial coolants consume the most water. The cooling water of the closed circulation cooling system must be treated as it must not corrode and scale the metal. This process is called water stabilization. Here, zinc sulphate powder is used as a water quality stabilizer.
  • Medicine
    • Oral zinc sulfate can correct zinc deficiency and restore the function of the enzymatic system. Zinc ions can precipitate proteins, have an astringent and bactericidal effect for external use, and can help the formation of granulation tissue.
    • Medicinal zinc sulphate powder is suitable for the treatment of enteropathic adenodermatitis, aphthous, chronic ulcer, and conjunctivitis caused by zinc deficiency. However, sharing with penicillamine may weaken the effectiveness of the latter. Zinc Sulphate Powder Monohydrate can be used as a zinc supplement in feed.

    • Zinc sulphate powder can also be used to prevent disease in fruit tree seedlings. It is also a commonly used fertilizer to supplement crop zinc trace element fertilizer. It can be used as base fertilizer, foliar fertilizer, etc.
    • Zinc is one of the essential nutrients for plants. If zinc is deficient, white flower seedlings are likely to form on corn, and if zinc deficiency is severe, growth stops or the seedlings die. If the pH value is high, zinc fertilizer such as zinc sulphate powder should be added, and increasing the application of zinc fertilizer also has the effect of increasing the yield.

Adapted symptoms (for reference only):

  1. Astringent antiseptic: Eye drops can be used for conjunctivitis, trachoma and blepharitis.
