Application
Industry
1. When electrolyzing sodium chloride aqueous solution, hydrogen and chlorine will be produced. Chlorine is widely used in chemical industry and can be used to synthesize polyvinyl chloride, pesticides, hydrochloric acid and so on.
2, Danse method of sodium metal: through the electrolytic melting of sodium chloride and calcium chloride mixture preparation of sodium metal. "Calcium chloride is used as a flux to reduce the melting point of sodium chloride below 700 ° C." Calcium is less reducing than sodium and does not introduce impurities.
3, sodium chloride is necessary for many biological reactions, such as molecular biology tests contain sodium chloride in a variety of solution formulations, most of the bacterial culture medium contains sodium chloride. At the same time, it is also the raw material for the ammonia - alkali method of soda.
4. Inorganic and organic industries are used as raw materials for the manufacture of caustic soda, chlorate, hypochlorite, bleaching powder, refrigerant of freezing system, raw materials for organic synthesis and salting out agents. It is used as a heat treatment agent in the steel industry. High temperature heat source with potassium chloride, barium chloride and other salt bath, can be used as a heating medium, so that the temperature is maintained between 820 ~ 960ºC. In addition, it is also used in glass, dye, metallurgy and other industries
5. Analytical reagents are used as fluorine and silicate microanalytical reagents.
6, Hou alkali method soda: the second step: the first step of ammonium bicarbonate solution and sodium chloride solution mixed, at 10ºC to get sodium bicarbonate and ammonium chloride.
Food Industry
It is used in salting by the food industry and fishing industry, as an ingredient for seasoning and as refined table salt.
Adding salt to cooking dishes can remove some of the peculiar smell of raw materials and increase the taste, which is the freshness of salt. "Light and tasteless, salty and tasteless" means that the amount of salt should be appropriate to play its unique function.
Medical treatment
Sodium chloride is very important for life on Earth. Most biological tissues contain a variety of salts. The concentration of sodium ions in the blood is directly related to the regulation of safe levels of body fluids. The conduction of nerve impulses resulting from signal switching is also regulated by sodium ions.
Water containing 0.9% sodium chloride is called saline because it has the same osmotic pressure as plasma. Saline is the primary fluid substitute and is widely used for the treatment and prevention of dehydration, as well as intravenous therapy and prevention of hypovolemic shock.
Humans, unlike other primates, secrete large amounts of sodium chloride through sweating.
Sodium chloride is indispensable to man. The total amount of sodium ions contained in the adult body is about 60g, 80% of which is found in the extracellular fluid, namely in plasma and intercellular fluid. Chloride ions are also found mainly in the extracellular fluid. The main physiological functions of sodium and chloride are:
(1) to maintain the osmotic pressure of extracellular fluid;
(2) participates in the regulation of acid-base balance in the body;
(3) Chloride ions are involved in the production of gastric acid in vivo. In addition, sodium chloride also plays a role in maintaining the normal excitability of nerves and muscles.
Agriculture
Its aqueous solution can be used for seed selection. NaCl solutions were prepared as required by the species and were denser than water. Seeds were placed into NaCl solution, floating unplump, sinking plump.
Other
Sodium chloride can significantly increase the capacity of a hard drive, according to new findings published by the Technology Research Institute of Singapore. Specifically, the existing traditional hard disk uses random disk storage technology, which can only achieve a data density of 0.5 terabytes per square inch. The new technology, with the help of sodium chloride and a new high-resolution lithography factor, will allow a more orderly data density of 3.3 terabytes per square inch without the need for complex equipment upgrades. With this technology, a 1TB hard disk can achieve a 6TB capacity without adding platters.
