Nacl

Описание

Sodium chloride(Nacl) has a wide range of uses in industry, mainly including the following aspects:

1. Manufacturing chemical products: Sodium chloride is an important raw material for manufacturing chemicals such as chlorine, hydrogen, hydrochloric acid, caustic soda, etc. For example, hydrogen and chlorine can be produce for electrolyzing sodium chloride aqueous solution. And chlorine can be further use to synthesize polyvinyl chloride, pesticides, hydrochloric acid, etc.
2. Metallurgical industry: Sodium chloride(Nacl) is use for the metallurgical industry to manufacture metallic sodium and chlorine. Metallic sodium can be produce for electrolyzing a mixture of molten sodium chloride and calcium chloride. Calcium chloride is use for a flux to reduce the melting point of sodium chloride to below 700°C.
3. Food industry: Sodium chloride is use for a condiment and preservative in the food industry. The main component of table salt is sodium chloride. Which can remove some odors from food and increase its deliciousness.
4. Pharmaceutical industry: Sodium chloride is use for the pharmaceutical industry to manufacture drugs and disinfectants. For example, saline (0.9% sodium chloride solution) is the main body fluid substitute. Widely use for treat and prevent dehydration, and also used for intravenous injection therapy and prevention of hemolytic shock.
5. Other industrial uses: Sodium chloride is also used in glass, dye, metallurgy and other industries. For example, it is use for a raw material for the manufacture of caustic soda, chlorate, hypochlorite, bleaching powder, and a refrigerant for refrigeration systems in inorganic and organic industries; it is use for a heat treatment agent in the steel industry; it can be use for a heating medium in a high-temperature heat source in a salt bath with potassium chloride, barium chloride, etc. to maintain the temperature between 820 and 960°C.
   In summary, sodium chloride has a wide range of industrial uses. It is not only a basic chemical raw material, but also plays an important role in many industries.
