zinc sulfate and it’s usage in industry

Specifications of zinc sulfate

Zinc sulfate is a crystalline, colorless solid. This salt exists in the form of one, six and seven water crystals or salts without water. Among the various forms of sulfate, Haft Abe is of special importance. The most important applications of zinc are in agriculture, medicine, dyeing industries and water and wastewater treatment.

Zinc sulfate is a mineral in the form of white crystals and a combination of Zn and sulfur, which is a product of zinc metal. Due to the decomposition of this substance, it produces sulfur oxides. Its salt form is often used as a medicine or dietary supplement for Zn. It is also used as fertilizer in agriculture. Zinc sulfate is available in various forms in the form of tablets, granules, capsules and solutions for various uses.

• Hexahydrates

Hexahydrate with the chemical formula ZnSO4 • 6H2O has a monoclinic or hexagonal crystal structure. Its density is 2.072 g / cm3 at 15 ° C and it loses all its water molecules at 70 ° C.

• Hepta hydrate

The type of heptahydrate with the chemical formula ZnSO4.7H2O is colorless crystals with rhombohedral structure. Its density is 1.957 g / cm3 at 25 ° C and melts at 100 ° C. At 280 degrees Celsius we will see the loss of all water molecules in hepta hydrate.

Decomposes at 500 ° C. It has a high solubility in water so that 96.5 g / 100mL of this substance dissolves in water at a temperature of 20 ° C. Heptahydrate also has good solubility in glycerin but is insoluble in alcohols.

As shown below most market this product as a variety of Hpta, monohydrate, anhydrous and hexa-hydrate belong :

Applications of zinc sulfate

• Zinc sulfate in industry

Zinc sulfate is used in the preparation of various animal feed and chemical fertilizers . It can also be used to prevent the growth of different types of moss at different levels. This substance is used as a chemical that provides zinc in the production of various chemical drugs. Its solution is also used as an electrolyte solution to separate zinc from its compounds in the industrial process of zinc extraction. To coat zinc, it is used in electrolytes, it can also be used as a preservative in dyeing and leather.

• Zinc sulfate in agriculture

In general, the sulfate family is a good material for use as fertilizer in agriculture. From this family, ZnSO4 and manganese sulfate are the best materials for agricultural use, the combination of this material with other micronutrients is used as a pesticide and herbicide. Sulfates are added to animal feed to control common diseases.

Zinc binds to protein bands or organic acids in plants. For this reason, if it is added to the soil in high concentration and finally reaches the plant, the leaves of the plant turn yellow. The introduction of this sulfated compound into the soil and its conversion to zinc ions depends on factors such as soil pH and the solubility of this substance in water. In other words, these are the factors that cause zinc to be absorbed into other substances. The presence of zinc in the soil reduces the toxicity of sodium in plants.

In addition to its application in agriculture, zinc sulfate has various applications in industry, and we will describe several of them here:

• Anti-adhesion agents
• Chemical distributors
• Corrosion inhibitors and anti-scaling agents
• Used as a flocculant.
• It is used to clean and prepare hair care products.
• Oral use of zinc sulfate reduces acne or pimples.

• Pigment

Zinc sulfate is used to make lithopone pigment (white zinc). This white pigment has many different uses that are also used in paints, inks, leather, paper and cosmetic powders. As you know, lead is a toxic white, so using this pigment can be a good alternative. From the combination of insoluble substances including zinc sulfide and barium sulfate, lithopone pigment is obtained which precipitates by mixing barium sulfide and zinc sulfate solution.

• Zinc sulfate in medicine

Zn is a very useful substance that is used to treat zinc deficiency in the body. If this drug is used in combination with calcium tablets and other dairy products, its effect will be less and it will be less absorbed in the body. Toxicity can also occur if this drug is used in combination with other vitamins and herbal supplements. And…

Sales of zinc sulfate in the global market

In South American as well as less developed Asian countries, the demand for zinc sulfate for use in the medical industry is increasing due to health problems due to Zn deficiency. Also, improving the export of agricultural products by increasing production efficiency in developed countries has led to a peak in demand for this product by the industry producing chemical fertilizers, the impact of which on the market for the sale of this chemical can not be ignored.

Processed chemicals are traded around the world for a variety of purposes. Zinc oxide is one of the most important zinc oxide chemicals and  buying and selling zinc oxide is common for these purposes.

for example :

Due to the use of some zinc compounds in industries related to rims and rubber, industries related to agriculture and construction industries, and on the other hand, reducing the amount of this metal in soils of different regions due to consumption, the need to use additives of these materials Will be growing.

Based on these needs assessments, it is predicted that in the period from 2015 to 2030, the volume of sales of processed products will grow by 4% annually. In addition, the occurrence of some events in the world, such as the epidemic of coronavirus and proving the use of this metal to reduce lung damage and the recommendation of some doctors to take zinc tablets, including Zinc Plus tablets, increases the need for this Chemical compounds will be valuable. As a result of these changes, sales of zinc compounds, including zinc sulfate, have jumped.
