Preparation :
It is obtained by decomposition or neutralization of magnesium oxide, magnesium hydroxide, magnesium carbonate, magnesite, etc. with sulfuric acid as raw material. It is also used to make a potassium chloride by-product as a raw material which, after bromine production, is mixed with magnesium-containing mother liquor and then cooled and crystallized to give crude magnesium sulphate and then heated to filter, remove impurities and cool to give industrial sulphate. magnesium. It can also be obtained by heating, concentrating, crystallizing and separating bitterness or by carbonizing magnesium oxide and gypsum aqueous suspension.
Main purpose:
1. Agricultural use
Magnesium sulphate, sulfur and magnesium can supply crops with rich nutrients, help crop growth and increase yields, as well as help loosen soil and improve soil quality.
Symptoms of "sulfur" and "magnesium" deficiency:
2. Industry
It is used in tanning, explosives, fertilizers, papermaking, porcelain, printing inks, lead batteries, sodium glutamate and yeast. Magnesium sulfate, as well as other minerals such as potassium, calcium, amino acid salt, silicate, can be used as a bath salt and also as an auxiliary component of ABS and PVC resins.
3. Animal husbandry
Magnesium is usually fertilized between early spring and the end of the year until the grass provides enough magnesium. It can also be added to feed and drinking water to meet the growing demand for milk fat. In order to improve the quality and quantity of cows.
4. Building materials
After dissolving in water, magnesium sulfate can react with lightly burned powder to form magnesium oxysulfide cement. Magnesium sulfur dioxide has good fire resistance, thermal insulation, durability and environmental protection and is used in many areas such as fire door core panels, exterior wall insulation panels, silica treated insulation panels and fire protection panels.
5. Other uses
A small amount of crystalline water or non-crystalline water can be used as a desiccant and dehydrating agent for organic synthesis and feed and fertilizer. On
Precautions for transport: The packaging must be complete during transport and loading must be safe. During transport, make sure that the container does not leak, pack, fall or be damaged. Mixed transport and transport with oxidants and edible chemicals is strictly forbidden. Do not expose to sun, rain or high temperatures during transport. The vehicle should be thoroughly cleaned after transport. Follow the prescribed route when transporting by road.
Precautions: airtight operation, local exhaust. Avoid releasing dust into the air in the workshop. Operators must undergo special training and strictly follow operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical goggles, anti-poison workwear and rubber gloves. Avoid dust formation. Avoid contact with oxidants. Equipped with emergency leak treatment equipment. Empty containers can be harmful residues.
Storage instructions: Store in a cool, ventilated warehouse. Protect from fire and heat sources. Protect from direct sunlight. The package is sealed. should be kept away from the oxidizing agent, not stored together. The storage area should be equipped with suitable materials to prevent leakage.
Disposal method: Use a safe burial method for disposal. If possible, reuse the container or bury it in the prescribed place.
Packaging: 25 / 50KG woven bag lined with a plastic bag or according to customer requirements.
