Industrial salt, also known as industrial salt or chemical salt, is a basic chemical raw material widely used in chemical industry, metallurgy, petroleum, textile, medicine and other industries. It is made from natural salt mines through mining, processing, refining and a series of processes, the main component is sodium chloride (NaCl), but also contains a small amount of sodium sulfate, calcium, magnesium and other impurities. There are many kinds of industrial salt, which can be divided into industrial dry salt, industrial wet salt, industrial refined salt, etc., according to its use and different production processes.
1) Industrial dry salt: Industrial dry salt is made through the mining, washing, dehydration, drying and other processes of natural salt mines, with high purity, less impurities, uniform particles and other characteristics. Industrial dry salt is mainly used for the production of chlorine, caustic soda, hydrochloric acid and other basic chemical raw materials, as well as for the production of metallurgy, petroleum, textile and other industries.
2) Industrial wet salt: Industrial wet salt is the natural salt ore dissolved in water, through filtration, precipitation, crystallization and other processes made, containing a certain amount of water salt products. Industrial wet salt is mainly used for the production of chlorine, caustic soda, hydrochloric acid and other basic chemical raw materials, as well as for the production of metallurgy, petroleum, textile and other industries.
3) Industrial refined salt: Industrial refined salt is made on the basis of industrial dry salt or industrial wet salt through further refining, decolorization, impurity removal and other processes, with higher purity and lower impurity content. Industrial refined salt is mainly used for the production of high-purity chlorine gas, caustic soda, hydrochloric acid and other basic chemical raw materials, as well as for the production of medicine, food, electronics and other industries.
Application of industrial salt in various industries:
1) Chemical industry: Industrial salt is an important raw material for the production of chlorine, caustic soda, hydrochloric acid and other basic chemical raw materials, and is also a key raw material for the production of other chemical products such as sodium hypochlorite, potassium chlorate, sodium chlorate and so on.
2) Metallurgical industry: Industrial salt is mainly used in the metallurgical industry for the production of metal sodium, metal magnesium and other metals and their alloys, as well as for the smelting and refining of ores.
3) Oil industry: Industrial salt is mainly used in the oil industry for the production of drilling fluids, oil well cement and other oilfield chemicals, and for improving the recovery of crude oil.
4) Textile industry: Industrial salt in the textile industry is mainly used in the production of textile auxiliaries, dyes, pigments, etc., as well as for textile bleaching, dyeing and other processes.
5) Pharmaceutical industry: Industrial refined salt is mainly used in the pharmaceutical industry for the production of drugs, medical devices, etc., as well as for experimental research, biopharmaceutical and other fields.
6) Electronics industry: Industrial refined salt is mainly used in the electronics industry for the production of electronic components, batteries, etc., as well as for circuit board cleaning, etching and other processes.
Industrial salt, as an important basic chemical raw material, plays a pivotal role in various industries. With the progress of science and technology and the adjustment of industrial structure, the application scope of industrial salt will continue to expand, and the demand will continue to grow.
FAQ
Q: What is industrial salt?
A: Industrial salt refers to salt products used in industrial production and processing, mainly composed of sodium chloride. It is usually colorless or white crystal, with high solubility and low melting point and other physical properties, widely used in metallurgy, chemical, glass, food, medicine, environmental protection and other different industries.
Q: What are the main uses of industrial salt?
A: Industrial salt is used in many fields. In the metallurgical industry, it can reduce the melting point of metals and promote the melting and deoxidation reaction of metals. In the chemical industry, industrial salt is a key raw material for the production of basic chemicals such as chlorine gas and sodium hydroxide. In addition, it also plays an important role in soap manufacturing, ceramic and glass production, daily chemical industry and other fields.
Q: What are the production processes of industrial salt?
A: The production process of industrial salt is varied, common methods include extraction from sea water, the use of rock salt or salt lake brine as raw materials by sun drying, or by dissolving coarse salt, removing insoluble impurities after refining. In the laboratory, industrial salts can also be prepared by mixing hydrochloric acid with sodium hydroxide.
Q: What kinds of industrial salt are there?
A: There are various types of industrial salt, which can be divided into large grain salt, small white salt, refined salt and by-product salt. Depending on its chemical composition and use, industrial salts can also contain other salts, minerals, and impurities.
Q: What are the standards for industrial salt?
A: The standard of industrial salt mainly includes chemical composition, appearance, solubility, purity, packaging and storage conditions. For example, the content of sodium chloride should be more than 97%, and the content of other salts should be less than 3%. The appearance of industrial salt should be white crystal, no obvious impurities and granular matter. In addition, industrial salt should also meet specific requirements for packaging and storage to ensure its quality and stability.
Q: How to use industrial salt safely?
A: When using industrial salt, special attention should be paid to safety and environmental protection. Store in a dry, well-ventilated place, away from fire and flammable materials. When handling industrial salt, wear appropriate protective equipment, such as chemical acid and alkali resistant gloves, goggles or face masks. In addition, correct operating procedures should be followed to ensure that accurate amounts are used and that the operation is carried out in accordance with the guidelines provided by the manufacturer.
Q: Can industrial salt be used in cooking or food processing?
A: No. Although industrial salt contains sodium chloride, its composition is not pure and may contain impurities and contaminants that are not suitable for cooking or food processing. Consumption of industrial salt can cause poisoning or other health problems.
