Specific classification and application of Magnesium Chloride Hexahydrate


Magnesium chloride hexahydrate means that it contains six water molecules, the chemical formula MgCl2·6H2O. There are many processing technologies of magnesium chloride hexahydrate in magnesium chloride manufacturers. At present, magnesium chloride manufacturers mainly use two main production processes. One is magnesium chloride hexahydrate produced by brine method called halogen tablets, halogen powder, etc.; The other is magnesium chloride hexahydrate made by acid process, which is characterized by whiter color on the appearance of the product and better use effect.

Magnesium chloride hexahydrate Classification:
Magnesium chloride hexahydrate is divided into food grade, industrial grade and aquaculture feed grade according to different uses, and its main performance is different in product parameters.
1. Food grade: Mainly used in food as a coagulant or thickening agent, such as marinated tofu, etc., is mainly used in protein-containing foods.
2. Industrial grade: This part of the application is more extensive, mainly the use of its adsorption capacity as a desiccant, coagulant, release agent, flame retardant and so on.
3. Aquaculture grade: mainly use its magnesium, calcium, sodium, etc. to increase the absorption of trace elements in fish, shrimp, crabs, algae, vegetation, etc.
According to its shape, it is divided into hexahydrate magnesium chloride tablets, hexahydrate magnesium chloride particles, hexahydrate magnesium chloride powder, etc., mainly to facilitate the use of users. In the color is divided into a variety of such as clear, milk white, gray, brown, the first three are called white magnesium, and the latter is called Pu Mei. In the content of magnesium chloride content is divided into 43%, 44%, 45%, 46%, 47% of these several, the commonly used is magnesium chloride content of about 46%.

Magnesium chloride hexahydrate application:
1. Raw materials of chemical products: raw materials for the production of magnesium carbonate, magnesium hydroxide, magnesium oxide and other magnesium products.
2. Building materials industry: in magnesite products can be made of high quality magnesium tile, high quality fire-proof board, magnesium packing box, magnesium decoration plate, light wall panel,
3. Machinery industry: abrasive tools and stoves are mainly used as release agents.
4. Transportation industry: used as road deicing and melting agent, deicing speed is fast, and the role of preventing ice.
5. In coal mines: as a flame retardant, highway dust prevention agent, etc
6. Building materials: magnesium oxide and magnesite (MGO) for the preparation of hard corrosion resistant magnesium cement, can be used for the preparation of artificial marble, clay tile, floor, ceiling, decorative board, fire board, greenhouse support, inorganic glass steel greenhouse skeleton, magnesite insulation chicken coop, wave color tile, ventilation duct, partition panel, magnesite manhole cover, bathtub, door and window frame and mobile houses. It is used as antifreeze in winter construction.
7. Food industry: Magnesium chloride hexahydrate is a protein coagulant. Tofu made from salt water (food-grade magnesium chloride aqueous solution) is tastier than tofu made from gypsum. It is also used as an additive in some foods.
