Magnesium chloride has the effect of coagulating protein and is often used to make food. However, industrial magnesium chloride contains other ions, so it cannot be directly used in the food industry.
However, when a large amount of magnesium chloride enters the blood, it will cause the blood to coagulate, and there is no doubt that people will die. Magnesium chloride must be properly kept to avoid unnecessary accidents.
Magnesium chloride is a monoclinic crystal, which is especially easy to deliquesce in the air, and has a salty taste. The chemical properties of magnesium chloride are corrosive to a certain extent.
It is mainly used to make metal magnesium, disinfection ji, frozen salt water, etc. It is also used to fill fabrics and papermaking. In industry, magnesium chloride solution and magnesium oxide can be mixed to produce high-quality magnesia cement.
Magnesium chloride is white crystals at room temperature and is easy to absorb moisture. Here is an introduction to the appearance quality requirements of magnesium chloride:
1. The appearance color of magnesium chloride should be white or off-white or yellow-brown.
2. Magnesium chloride products should be fragmented or granular, not bulky crystals.
3. Magnesium chloride products cannot be deliquescent.
Magnesium chloride is an important part of sewage treatment, a water purifier composed of magnesium chloride. The water purifier contains raw materials such as polyferric chloride, polyaluminum chloride, magnesium chloride, polyacrylamide, etc. The use of these products is used to make sewage Clean up at once. Magnesium chloride itself can quickly remove impurities in the water without causing secondary pollution, and the speed is extremely fast.
The medicinal value of magnesium chloride
Magnesium chloride has a blood clotting effect, and magnesium chloride tablets are clinically valuable. In fact, magnesium chloride tablets can be used as a laxative.
Everyone should be aware that most laxatives are bitter. This taste comes from chloride ions. It can disturb stomach acid and act as a laxative. After the magnesium chloride tablet is dissolved, it produces a large amount of chloride ions, which is very effective as a laxative.
Industrial-grade magnesium chloride is mainly used as a raw material for electrolytic production of metallic magnesium. It is also used to produce oxychloride cement, refrigerating brine, flocculants, organic reaction catalysts, magnesium fluxes and welding agents. Food-grade magnesium chloride can be allowed to be used in soy products in a limited amount.
Chemical name: Magnesium chloride (MgCl2)
Uses: used to make metal magnesium, frozen brine, ceramics, and used to fill fabrics, papermaking, etc. Its solution is mixed with magnesia to become hard and wear-resistant magnesia cement.
Preparation method: prepared by the action of magnesia or chalcogenite and salt. Magnesium chloride exists in sea water and bittern.
