1、Chemical Name:Magnesium Chloride
2、Molecular Formula: MgCl2 ; MgCl2·6H2O
3、Molecular Weight: 95.20 ; 203.30
4、CAS: 7791-18-6
5、Character: It’s white flake or granular crystal. At high temperature, it’ll decompose to hydrogen chloride and magnesium oxide.
6、Usage: It can be used to make tofu (bean curd). Tofu with brine (solution of Magnesium Chloride) is far more tender and delicious than with gypsum. It also can be used as food additives in other food industries.
Metallurgical industry
It is used to make refractory materials and binders for building furnace arms, and is the raw material for making No. 2 flux and smelting metal magnesium.
chemical industry
It is mainly used to make various magnesium salts, such as magnesium oxide, magnesium hydroxide, magnesium carbonate, firecracker solidifying agent, and also used as the raw material of antifreeze.
building materials
Made of hard and corrosion-resistant magnesia cement with magnesite (MgO), it can be made into artificial marble, earthen tile, floor, ceiling, decorative board, fireproof board, greenhouse support, inorganic glass fiber reinforced plastic greenhouse skeleton, magnesite insulation chicken Shelters, corrugated tiles, ventilation ducts, partition boards, magnesite manhole covers, bathtubs, door and window frames and prefabricated houses, etc. It is used as antifreeze during construction in winter.
mechanical Engineering
In daily life, lozenge earth can be used to make mechanical packing boxes, triangular cushions and furniture, etc. It is a good material for "substituting soil for materials".
Food Industry
is a protein coagulant. The tofu ordered with brine (food-grade magnesium chloride aqueous solution) is more tender and delicious than the tofu ordered with gypsum, and is also used as an additive for some foods.
Transportation Industry
Used as a road ice and snow melting agent, the speed of ice melting is fast, and it is less corrosive to vehicles, which is higher than the effect of sodium chloride.
medicine
Made of magnesium chloride "halogen" can be used for medicinal purposes.
agriculture
It can be used as magnesium fertilizer, potassium magnesium fertilizer and cotton defoliant.
other information
In addition, it can also be used as coal mine fireproofing agent, road dustproofing agent and soil stabilization.
7、Packing: It is packed with polythene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.
8、Storage and Transport: It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from poisonous substances.
