Zinc Sulfate Hepta Hydrate

ZINC HEPTA

Zinc sulphate (chemical formula: ZnSO4) is one of the most important zinc salts, is a colourless rhombohedral crystal or white powder, its heptahydrate is commonly known as alum, is a natural mineral. It is a natural mineral. It is less likely to be agglomerated if it contains 1 molecule of water of crystallisation. Relative density 1.97, melting point 100℃. Minimum lethal dose (rat, oral) 2200mg/kg. irritating. Used in the manufacture of Lidl powder, and used as mordant, astringent, wood preservative and so on.

Application Areas
Industry
It is the main raw material for the manufacture of zinc barium white and zinc salts, and can also be used as a printing and dyeing mordant, a preservative for wood and leather, and an important auxiliary raw material for the production of viscose fibres and vinylon fibres. [3] It is also used in the electroplating and electrolysis industries and in the manufacture of cables. Cooling water is the largest amount of water used in industry. Cooling water in a closed loop cooling system can not have corrosion and scaling of metals, so it should be treated, this process is called water quality stabilisation, zinc sulphate is used as a water quality stabiliser here.
Agriculture
It can be used to prevent diseases in fruit tree nurseries, and is also a commonly used fertiliser to supplement zinc trace element fertiliser in crops, and can be used as a base fertiliser, foliar fertiliser, etc. Zinc is one of the necessary plant nutrients, zinc deficiency in maize is easy to appear white flower seedlings, serious zinc deficiency stops growth or even seedling death, especially for some sandy loam or pH value is too high for the field should be more zinc fertiliser such as zinc sulphate, zinc fertiliser and increase the effect of yield. Fertiliser method: take 0.04~0.06 kg of zinc fertiliser, 1 kg of water, mix 10 kg of seeds, heap boring 2~3 hours sowing. Before sowing the zinc fertiliser is applied to the inter-root layer, 0.75~1 kg per mu. If the leaf colour is pale during the seedling stage, you can spray zinc fertilizer, with a dosage of 0.1 kg per mu.
