Zinc Sulfate Heptahydrate Powder

What is Zinc Sulfate Heptahydrate?

Zinc Sulfate Heptahydrate Powder,also known as zinc sulfate and zinc sulfate, is an inorganic compound with a molecular formula of ZnSO4·7H2O, usually a white crystalline substance. It is easily soluble in water and gradually weathers in dry air.

This substance appears as white granules or powder at room temperature, has astringency, is easily soluble in water, slightly soluble in ethanol and glycerol, loses water when heated to 200°C, and decomposes at 770°C. This compound is easily weathered in dry air, loses part of its crystal water to form a low hydrate, and may deliquesce in a humid environment. It has a wide range of applications in many fields, and is also used in medicine, artificial fibers, electrolysis, and the production of zinc salts.

Features

1. Easily soluble in water, slightly soluble in alcohol and glycerol, insoluble in liquid ammonia and ketone.
2. At different temperatures, it can be converted into zinc sulfate hexahydrate or zinc sulfate monohydrate.
3. It starts to lose water when heated to 200°C and completely decomposes at 770°C to produce zinc oxide and sulfur trioxide.

Function

Nutrition supplement: Zinc Sulfate Heptahydrate Powder can provide zinc to crops, promote photosynthesis, protein synthesis and the formation of auxin, thereby enhancing crop productivity.

Improve crop quality: By promoting the absorption of nutrients in crops, it can increase crop yields and fruit quality.

Prevent and control zinc deficiency symptoms: It can effectively prevent and control crop diseases caused by zinc deficiency, such as corn white seedlings, rice dead seedlings, etc.

Promote wound healing: It can promote the healing process of wounds and has a certain antibacterial effect.

Enhance immunity: Zinc is an essential trace element and is very important for maintaining the normal function of the immune system.

Applications

Food

As a zinc fortifier, it is used in salt, infant food, dairy products, cereals and their products, drinking liquids and milk beverages.

Medicine

Zinc supplements: used to treat symptoms such as loss of appetite, anemia, and growth retardation caused by zinc deficiency.

Auxiliary treatment: used for auxiliary treatment of rheumatoid arthritis, acne, chronic ulcers, conjunctivitis, mouth sores, etc.

Agriculture and feed

Agriculture: used to produce pesticides and prevent and control pests and diseases.

Feed additives: as a zinc supplement in feed, Zinc Sulfate Heptahydrate Powder promotes animal growth, improves hair quality, and affects reproductive function.

Industry

Mordant: in the textile industry, it is used as a mordant to help dyes adhere better to fibers.

Wood preservative: used to treat wood to prevent it from rotting and extend its service life.

Production of zinc salts: an important raw material for the manufacture of other zinc compounds.

Preparation Method

Step 1: Grind zinc oxide to 60 mesh, add it to a mixing tank containing waste acid from titanium dioxide production, and start steam heating and stirring. The liquid-to-solid ratio is 6-8:1, heat to 65℃-80℃, and control the reaction at this temperature for 2h-3h; the composition of the waste acid: free sulfuric acid (%) 15-35, ferrous sulfate (%) 5-20;

Step 2: Send the reaction liquid in the mixing tank to the filter press, adjust the angle washing time to 3min, and send the filtrate and washing liquid to the next mixing tank together;

Step 3: Turn on stirring and steam heating, add lime milk to adjust the pH value to 4.5 -5.5, blow air into the solution, heat to 70℃-80℃, and control the reaction at this temperature for 30min-1h;

Step 4: Continue to add 30% hydrogen peroxide to the solution, the reaction time is 1h, and the amount added is solution: hydrogen peroxide = 10:1;

Step 5: After the reaction is completed, send the solution to the filter press, control the corner washing time to 5min, and send the filtrate and washing liquid into the evaporation equipment together;

Step 6: Under slow stirring, evaporate the solution until more crystals are precipitated, quickly cool to 40℃-45℃, crystallize for 3h, and then quickly cool to room temperature.
