The chemical formula of magnesium chloride usually contains six molecules of crystal water, that is, d. It is easy to deliquesce and will weather and lose crystal water when placed in dry air. It is a monoclinic crystal that has a salty taste and is corrosive to a certain extent. It is used to make magnesium metal, disinfectants, frozen brine, ceramics and fill fabrics, paper making, etc. Its solution is mixed with magnesium oxide to form hard and wear-resistant magnesia cement.
Uses
It is an important inorganic raw material in the chemical industry and is used to produce magnesium carbonate,
magnesium hydroxide
, magnesium oxide and other magnesium products. It is also used as
antifreeze Raw materials for pharmaceutical preparations, etc.
, used in the metallurgical industry to produce metallic magnesium
(produced by melt electrolysis
), liquid chlorine and high-purity
magnesia
, etc.
In the building materials industry, it produces light building materials such as fiberglass tiles, decorative panels, sanitary ware, ceilings, floor tiles, magnesia cement
Ventilation ducts
Anti-theft manhole covers
Fireproof doors and windows
Fireproof board
Partition board
An important raw material for the production of artificial marble and other high-rise building supplies. Magnesite products can be used to make high-quality magnesium tiles, high-quality fireproof boards, magnesium packaging boxes, magnesium decorative panels, lightweight wall panels, abrasive tools, stoves, fireworks fixing agents, etc.
In other fields, it can be used as food additives, protein coagulants,
snow melting agents
, refrigerants, dust-proof agents, refractory materials, etc. Tofu made with
brine
(magnesium chloride aqueous solution) is tenderer and more delicious than tofu made with gypsum
. Metallurgical industry: used to make refractory materials and The adhesive used to build the furnace arms is not the raw material for manufacturing No. 2 flux and smelting magnesium metal.
. Machinery industry: In daily life, rhodopsin can be used to make triangular pads for mechanical packaging boxes and furniture. It is a good material for substituting soil for materials.
.Transportation industry: Used as road ice and snow melting agent, the ice melting speed is fast and less corrosive to vehicles
Higher than
sodium chloride
.
.Medicine: Made from magnesium chloride
Dried in halogen
It can be used for medicinal purposes.
Can be used as a laxative.
Agriculture: It can be used to make
magnesium fertilizer
Potassium-magnesium fertilizer and cotton defoliant.
