What is magnesium chloride used for?

Magnesium chloride is an important inorganic raw material in the chemical industry. It is a colorless flaky crystal, slightly soluble in acetone, soluble in water, ethanol, methanol, and pyridine. It deliquesces and smokes in humid air, and sublimes when it is white hot in the hydrogen gas stream, and can form hexahydrate, that is, magnesium chloride hexahydrate, which contains six crystal waters. 

Summary of uses of magnesium chloride

1. Application of industrial grade magnesium chloride

1). Used in the production of magnesium carbonate, magnesium hydroxide, magnesium oxide, metal magnesium, liquid chlorine and high-purity magnesia and other products.

2). It is used to make refractory materials and binders for furnace arm, and is the raw material for making No. 2 solvent and smelting metal magnesium.

3). Used as road deicing and deicing agent, deicing speed is fast, less corrosive to vehicles and less destructive to soil. Its liquid form can be used for road antifreeze measures. It is often sprayed on roads before winter rains to keep them from icing. Therefore, the vehicle can be prevented from skidding and traffic safety can be ensured.

4). In the building materials industry, it is the production of light building materials such as glass fiber tiles, decorative panels, sanitary ware, ceilings, floor tiles, magnesia cement, ventilation pipes, anti-theft manhole covers, fire doors and windows, fire panels, partition panels, artificial marble, etc. An important raw material for high-rise building supplies. In magnesite products, it can be used as high-quality magnesium tiles, high-quality fireproof boards, magnesium packaging boxes, magnesium decorative panels, lightweight wall panels, molds, stoves, and firework fixing agents.

5). Dust control, able to absorb moisture in the air, so it can be used in dusty places to suppress the dust to the ground to prevent small dust particles from spreading in the air. It is often used in excavation sites, indoor sports venues, horse farms, etc.

6). Hydrogen storage, this compound can be used to store hydrogen. A molecule of ammonia has an abundance of hydrogen atoms. Ammonia can be absorbed by the surface of solid magnesium chloride. Ammonia is liberated from magnesium chloride by slight heating, and hydrogen gas is obtained through the catalyst.

7). This compound can be used to make cement. Due to its non-combustible properties, it is often used in various fire protection equipment. The textile and paper industries also take advantage of this.

8). Magnesium chloride is used as a viscosity control agent in cosmetics and skin care products.

9). It can be used as magnesium fertilizer, potassium magnesium fertilizer and cotton defoliant.

10). Softener and fixative in detergent. 

11). As a natural decolorizing agent, it has a great effect on the decolorization of reactive dyes.

12). As an additive for silica gel products, magnesium chloride modified silica gel can significantly increase the hygroscopic performance.

13). Nutrients for microorganisms in sewage treatment (can promote the activation of microorganisms).

14). Moisturizing agent and stabilizer of particles in the ink to improve the vividness of the color. 

15). Moisturizing agent and particle stabilizer of color powder to improve the vividness of color.

16). An additive for polishing ceramics, which can improve surface gloss and strengthen hardness.

17). Raw materials for insulating coatings on the surface of integrated circuit boards.

18). Raw material for fluorescent paint.

2. Application of food grade magnesium chloride

1). Magnesium chloride can be used as a tofu coagulant, which is characterized by tender and elastic tofu with a strong bean flavor.

2). The protein coagulant of dried tofu and fried tofu, the dried tofu and fried tofu are not easy to break.

3). Fermenting agent for Japanese sake, etc.

4). Water remover (for fish cake, dosage 0.05% ~ 0.1%).

5). Texture improver (combined with polyphosphates, as an elastic enhancer for surimi and shrimp products), because of its strong bitter taste, the usual amount is less than 0.1%;

6). Mineral enhancer, used in health food, health drink. Magnesium chloride is also a component of infant formula.

7). In addition, it has been widely used in the production and processing of salt, mineral water, bread, aquatic product preservation, fruits and vegetables and other industries. In the process of food processing, it can also be used as curing agent, leavening agent, protein coagulant, water remover, starter, tissue improver, etc. It is also used as a nutritional enhancer; a taste agent (combined with magnesium sulfate, salt, calcium hydrogen phosphate, calcium sulfate, etc.); a wheat flour treatment agent; a dough quality improver; an oxidant;

3. Application of pharmaceutical grade magnesium chloride

Since it is rich in magnesium, it is the most effective nutritional supplement. Available in tablet and capsule form. Magnesium is an essential element for various functions of the body. It helps strengthen bones and teeth and prevents blood from clotting. Taking proper doses can prevent serious diseases such as heart disease, osteoporosis, etc.

1). It is the raw material of gastric cancer medicine, which has a certain protective effect on gastric mucosa.

2). One of the necessary raw materials for artificial seawater.

3). One of the raw materials of bath salt, which can play the role of sweating.

4). Raw material for kidney dialysis.

5). It has a certain anesthesia and sedative effect on mammals.

6). Magnesium chloride can disturb the stomach, and laxatives contain magnesium chloride.
