Competitive Advantages of Our Company

WIT-STONE cooperates with reputable large manufacturers in the raw material procurement of zinc sulfate monohydrate. After the raw materials are purchased into the factory, the raw materials shall be inspected first, and then the raw materials warehouse shall be coded and stacked for quality tracking in the future. WIT-STONE has purchased the most advanced production equipment and testing equipment of zinc sulfate monohydrate in the world to provide customers with the best quality products and services. Before production, the raw material zinc oxide shall be rinsed; During the production process, multi-effect evaporator and hot-air dryer are used for evaporation and drying, which is environmentally friendly and efficient. After the production of the product is completed, the finished product is inspected by atomic absorption spectrophotometer and polarographic analyzer, and can be delivered only after passing the inspection.

In addition, some customers asked about the causes of zinc sulfate caking, mainly including:

1. The raw materials are not rinsed during production, and the chloride ion content is too high, which is easy to agglomerate;

2. The temperature of the zinc sulfate produced is very high. Many manufacturers fill the zinc sulfate too early due to rush or site reasons, which leads to high temperature in the packaging bag. In addition, there is no ventilation or high temperature during long-distance transportation, which causes zinc sulfate agglomeration.

In order to effectively solve the problem of zinc sulfate agglomeration, Changsha Ruiqi Chemical Products Co., Ltd. will add a rinsing process after purchasing raw materials to remove chloride ions in raw materials; For zinc sulfate monohydrate, a new drying procedure is added to the original process to reduce the surface moisture of zinc sulfate monohydrate and avoid agglomeration during transportation.

Production method of our company:

The company's production process method is that zinc oxide reacts with sulfuric acid solution to form a first stage acid leaching solution and a first stage acid leaching residue, adding hydrogen peroxide and zinc oxide to the first stage acid leaching solution to oxidize and precipitate iron, adding the first stage acid leaching residue to sulfuric acid solution for second stage acid leaching, and then pressing filtration to form a second stage acid leaching solution and a second stage acid leaching residue, adding scrap iron and P204 to the second stage acid leaching solution, and reacting the second stage acid leaching solution with zinc oxide, Conduct iron removal and neutralization, add zinc powder for replacement and purification, and then add the secondary acid leaching solution that has been replaced and purified into the primary acid leaching solution. The zinc sulfate monohydrate crystal is obtained by three-effect evaporation crystallization using hot steam. This production process improves the zinc content in the acid leaching solution and reduces the cadmium content in the acid leaching solution, which not only improves the product quality, but also improves the utilization rate of raw materials and product output rate; At the same time, the three-effect evaporation crystallization of acid leaching solution is adopted to reduce the heat vapor required for evaporation crystallization, thus reducing the heat consumption.

Zinc sulfate Application in agriculture and feedstuff

Zinc (Zn), one of the micronutrients and essential elements and an important builder of various enzymes and proteins – only in small amounts – is required by plants. However, it is very important for plant growth because it plays a role in a wide variety of processes. The normal range of zinc in plant tissue is 15-60 ppm.

Although zinc poisoning does not occur, it can negatively affect the growth and quality of the crop in plants. Any deficiency or toxicity must be corrected before the damage to the product becomes irreparable.

The action of zinc activates enzymes that are responsible for the synthesis of certain proteins. This substance helps the plant to resist the cold in the formation of chlorophyll and some carbohydrates, the conversion of starch into sugars and its presence in the plant tissue. Zinc is essential in the formation of auxins that help regulate stem growth and proliferation.

Sometimes the extra Zn in the plant growth environment can compete with the absorption of phosphorus, iron, manganese or copper and cause their deficiency in the plant tissue. When the pH of the environment is low, zinc is considered a basic requirement for plant absorption. Zinc is also found in high amounts in some water sources, and zinc can also be found in water if it comes into contact with galvanized metal surfaces.

Zinc is found in most water-soluble fertilizers. Fertilizer zinc sulfate, ammonium nitrate-zinc or zinc chelate can be used. However, it is best to use a complete micronutrient fertilizer to avoid nutrient imbalances that lead to deficiencies in other micronutrients.

Feed grade zinc sulfate monohydrate is a zinc supplement for the feed industry. It is a white flowing powder with high zinc content and low impurity (lead and cadmium) content, which is superior to the safety standard for the use of feed additives.

 It has the functions of sterilization, bacteriostasis, deodorization and self-cleaning, and can effectively prevent diarrhea of young animals. It tastes better than ordinary zinc oxide and improves the palatability of feed. The dosage is only one ninth of that of ordinary zinc oxide, which greatly reduces the cost and avoids zinc waste and environmental pollution.

 It is an ideal zinc supplement and growth promoter in animal feed. It has good dispersion and fluidity. It is easily deliquescent in the air, soluble in water, slightly soluble in alcohol and insoluble in acetone.

The difference between zinc sulfate monohydrate and zinc sulfate heptahydrate

1.Difference in internal control content: zinc content of zinc sulfate monohydrate powder is more than 35%, while zinc sulfate heptahydrate powder is more than 21.5%. The zinc content of zinc sulfate monohydrate particles is more than 33%, and that of zinc sulfate heptahydrate particles is more than 21%. The particles are made of powder through disc granulation, and the zinc content is lost, so the zinc content of the particles will be lower than that of the powder.

2. Difference in water solubility: Generally speaking, the water solubility of zinc sulfate heptahydrate is better than that of zinc sulfate monohydrate, because zinc sulfate heptahydrate contains seven water molecules. However, in terms of production monitoring, generally, the water insoluble substances of zinc sulfate are qualified products within 0.05%. Both zinc sulfate monohydrate and zinc sulfate heptahydrate can be used as water-soluble fertilizers, depending on the method you use.

3. Price difference: Generally, the price of zinc sulfate is determined according to the zinc content of the product. The higher the zinc content, the higher the price. Therefore, zinc monohydrate powder is more expensive than zinc heptahydrate powder. The reason why zinc sulfate particles are more expensive than zinc sulfate powder is that the cost of manufacturing zinc sulfate particles has increased labor costs.

Usefulness of Feed Grade Zinc Sulphate Monohydrate

Zinc is an essential trace element for all animals. It exists in all tissues and organs of the body, mainly in bones, muscles, liver, kidneys and skin; At the same time, feed-grade zinc sulfate itself also has the functions of astringency, antisepsis, sterilization and pain relief. The trace elements necessary for the growth and breeding of sheep are indispensable in sheep feed. The role of zinc sulfate in sheep feed: when the zinc in sheep feed is deficient or the zinc in sheep feed is not easily absorbed by sheep, sheep will suffer from zinc deficiency, which will lead to the emaciation of sheep's body, thickening of skin, obvious atrophy of breeding sheep's testicles, low sperm, and impact on growth and breeding. Therefore, sheep feed should not be deficient in zinc. In some zinc deficient sheep feed, zinc should be supplemented appropriately.

Zinc sulfate can prevent zinc deficiency in sheep, prevent diarrhea in piglets, prevent and treat foot rot disease in dairy cows, prevent skin dyskeratosis, treat ulcerative colitis, and prevent and treat vision loss.

Advantages and application of aquaculture: zinc sulfate monohydrate is a colorless needle-shaped crystal, easily soluble in water, and is commonly used in aquaculture to kill ciliates. Zinc sulfate is a heavy metal salt insecticide, which is used to control the fixed ciliate disease of aquatic animals such as crab and shrimp. In addition, feed-grade zinc sulfate contains a variety of mineral elements, which can effectively regulate the internal and external osmotic pressure of shrimp and crab cells in the water, effectively inhibit the stress response of shrimp and crab when the salinity of the water drops, and also play the role of epidermal convergence, making the body surface of shrimp and crab clear.


History of zinc sulfate

Zinc sulfate is an inorganic compound consisting of zinc cation and sulfate anion. This substance is solid, colorless, odorless and crystalline. Historically, this substance is known as white vitriol. Zinc sulfate is easily soluble in water, slightly acidic and slightly soluble in ethanol and glycerol.

Zinc sulfate has non-oxidizing, non-flammable and non-combustible properties. This material is naturally deliquescent and can be formed in four hydrated states. Zinc sulfate is produced artificially from the combination of zinc ash and aqueous sulfuric acid.

Zinc (Zn) is an essential mineral for human, animal and plant nutrition. Zinc is also found naturally in the environment, food and water. Zinc is an essential component of enzymes involved in metabolic reactions.

In addition, zinc is essential for DNA repair and protection against oxidative stress. Zinc sulfate tablets are used as a source of zinc in zinc deficiency diseases. Zinc sulfate is recommended as a dietary supplement for the treatment of zinc deficiency in humans. For a long time, this prescription has existed and its dosage is adjusted according to the physical needs of each person.

Zinc sulfate is used as fertilizer and agricultural sprays to compensate for zinc deficiency in crops and improve the nutritional value of the soil. Zinc sulfate is used in animal feed to treat zinc deficiency in animals.

Zinc sulfate is also used as a preservative or preservative for leather, wood and leather. This compound is used for water purification process, flotation process and separation of minerals, production of white paper and electrical shift.

This material is used as a raw material for the production of latex products, desulfurization process. The pigment “zinc lithopone sulfate” is a herbicide commonly used to control moss growth.

The uses and applications of zinc sulfate were very much considered over time during different periods as raw materials for the groom of fertilizers and animal feed supplements. This substance has been used for soil treatment for peanut, cotton, corn and citrus plants. It is also added to cattle and chicken feed.

Gradually, the fear of heavy metals entering animal feed led to less use of this substance in animal supplements. Zinc sulfate is preferred as a fertilizer to zinc oxide (ZnO), because its better solubility in water, low cost, and compatibility with all types of soil increase the demand for this material in the agricultural industry.

In addition, other fields of application such as the chemical industry and water treatment have a constant demand for this material and the market is expected to remain stable. Zinc sulfate may be toxic if consumed in large amounts.
