Magnesium chloride is used in various industries

Magnesium chloride is mostly used in chemical, building materials, metallurgy, machinery, transportation, agriculture and other industries. It is the basic material for forming the hardened body of magnesium cement products in magnesium products. Magnesium ventilation pipe, also known as glass pipe and inorganic FRP pipe, is a pipe reinforced with medium alkali glass fiber cloth with modified magnesium cement as cementitious material and organic or inorganic filling materials.

It has the characteristics of non combustion, corrosion resistance, high strength and light weight. It is widely used in residential buildings, hotels, hotels, large shopping malls, office building air conditioning engineering, mine ventilation, factory smoke exhaust, dust removal and other projects. In the ventilation of construction engineering, underground engineering and industrial site, the incombustible plexiglass steel exchange pipe and cement smoke exhaust pipe of high-rise building are replaced, and the galvanized iron exchange pipe with poor anti-corrosion performance is replaced.

Especially in underground projects with high humidity and areas south of the Yangtze River, the advantages are more significant. According to the building materials industry standard jc646-1996, magnesium ventilation pipe is divided into P pipe and D pipe according to its purpose. Class P pipe is mainly used in public buildings, civil air defense projects and industrial sites and mines where ventilation and air conditioning facilities are generally required. Class D pipe as ventilation pipe, smoke exhaust pipe and dust discharge pipe is mainly used for ventilation pipe and oil discharge pipe of residential buildings.

It is used to make sodium sulfide, pulp, glass, water glass, enamel, laxative and agent in barium salt. It is salt and a by-product of manufacturing. The chemical industry is used to manufacture sodium sulfide, sodium silicate, etc. The laboratory is used to clean barium salt. It is used in industry as raw materials for NaOH and HSO, as well as papermaking, glass, printing and dyeing, synthetic fiber, leather making, etc.

Organic synthesis laboratory sodium is a commonly used post-treatment desiccant. It is mainly used as filler for synthetic detergent. A cooking agent used in the paper industry in the manufacture of salt pulp. Glass industry is used to replace soda ash. Chemical industry is used as raw material for manufacturing sodium sulfide, sodium silicate and other chemical products. The textile industry is used to prepare nylon textile coagulation bath.

It is used in industry as a retarding agent. It is also used in nonferrous metallurgy, leather, etc. Make the hydrated product calcium sulphoaluminate form faster and accelerate the hydration and hardening speed of cement. The mixing amount of sodium is generally 0.5% ~ 2% of the quality of cement, the initial strength of concrete is 50% ~ 28 degrees, and sometimes decreases by about 10%, depending on the cement variety, curing conditions and mixing amount.

Magnesium chloride is generally used as a food additive. Tofu and fungus eaten around us use magnesium chloride as an additive.

Calcium chloride is a key chemical raw material, which is widely used in various industries:

1. Used for cold proof, maintenance and dust control of pavement: calcium chloride is a very good snow remover, concrete antifreeze and antifouling agent for pavement. In addition, it has excellent maintenance effect for ground and subgrade engineering.

2. Used in mining and manufacturing industry: calcium chloride is mainly used in the production of a surface active water solution, which can be sprayed on the mine pit and in the coal mine to control the amount of dust and reduce the risk factors of coal mine work. In addition, calcium chloride solution can also be sprayed on the outdoor coal seam to prevent the coal seam from cold.

3. Used in oil drilling: the relative density of calcium chloride aqueous solution is very high, which contains a lot of sodium ions. Therefore, as a preservative for drilling crew, it can moisten and help to remove drilling mud. In addition, calcium chloride can be mixed with other chemicals in oil mining as well sealing fluid. This compound is like a bottle stopper at the wellhead, which can work for a long time.

4. It is widely used as moisture-proof agent in industrial production field, and can be used for dry and impetuous of N2, CO2, radon gas, sulfur dioxide and other industrial gases; It can also be used as dehydrating agent for alcohol, ester, ether and acrylic emulsion. Calcium chloride solution is the key refrigerant for refrigeration unit and refrigeration.

5. Used in food enterprises: calcium chloride can be used as preservative, added in domestic water or drinks to improve the mineral water content and make food flavor. In addition, it can also be used as refrigerant and preservative for food quick freezing.

6. For agriculture and animal husbandry: spray wheat with a certain concentration of calcium chloride solution, spray fresh fruit, long-term storage. In addition, calcium chloride can also be used as animal feed material.
