What are the general uses of industrial salts? Uses of industrial salts

The uses of industrial salt are: alkali making, soap industry and the production of chlorine, sodium hydroxide, but also widely used in metallurgy, tanning, pharmaceutical industry and agriculture, animal husbandry and fishery, etc., in addition, in food, feed, leather, ceramics, glass, soap, dyes, oil, mining and metallurgy, medicine and other industrial sectors and water treatment, ice refrigeration, highway snow removal, etc., industrial salt has a wide range of uses.

Industrial salt is one of the most basic raw materials in the chemical industry, and its main components are sodium chloride, sodium nitrite, etc., which is known as the mother of the chemical industry. The main products of the basic chemical industry, such as hydrochloric acid, caustic soda, soda ash, ammonium chloride, chlorine, etc., are mainly produced with industrial salt as raw materials.

The main products of the basic chemical industry, such as hydrochloric acid, caustic soda, soda ash, ammonium chloride, chlorine, etc., are mainly used as raw materials for the production of industrial salt, and a large number of raw salts and processed salts are used as raw materials in the chemical industry to produce such as chlorine, bleaching powder, caustic soda and industrial salt.

Soda ash and other chemical products use chlorine and sodium, the main components of salt. The "salt" used in food and the "salt" used in industry are both of the same chemical composition, but the uses are different. Because the raw salt is a product of nature, and the refined salt is also obtained by the simple processing of the raw salt, in addition to the main ingredient sodium chloride, it also contains a variety of impurities, so it cannot be called sodium chloride, and the convention only uses one word "salt", specifically called sodium chloride as the main ingredient, such as raw salt, sea salt, well salt, rock salt, iodized salt, non-iodized salt, refined salt, large salt, crushed salt, washed salt, etc.

If it is a salt of other chemical components, it must be said with its specific trade name or chemical name, such as soda ash, baking soda, alum, ammonium sulfate, potassium nitrate, potassium chloride, diammonium hydrogen phosphate, etc., and must not be called "industrial salt" in general. I don't know when the name "industrial salt" appeared, and I analyze that it is derived from the concept of salt monopoly. From the program on May 9, it can be seen that an old salt industry base like Zigong City also calls the refined salt it produces "industrial salt".

This statement has two negative effects, one is that, as it is said on TV, "industrial salt" is sulfate and nitrate. The other is more harmful, which leads to the frequent accidental ingestion of toxic salts, resulting in food poisoning in the population. The reason for this is that the cooks in many of our places, most of whom are migrant workers, think that "industrial salt" and "edible salt" are only qualitative differences, and when there is no salt in the kitchen, they take something they think is salt (often sodium nitrite), which causes a catastrophe.

Therefore, the mention of industrial salt must be abandoned, otherwise it will cause endless harm.

It is generally used on softened water, also known as water softener.

The use of industrial salt: mainly used in alkali production, soap industry and the production of chlorine, sodium hydroxide, etc., in addition to food, feed, leather, ceramics, glass, soap, dyes, grease and other industries are widely used.

There is a big difference between industrial salt and edible salt in our daily life, and it is used more in the industrial field.

Details: Industrial salt is mainly used in alkali production, soap making and the production of chlorine and sodium hydroxide, and is also widely used in metallurgy, tanning, pharmaceutical industry, agriculture, animal husbandry and fishery.

The "salt" used in food and the "salt" used in industry are both of the same chemical composition, but the uses are different. Industrial salt, which cannot be consumed directly, but can be used for industrial purposes, is collectively referred to as industrial salt.

It is used in soap manufacturing, ceramics, glass production, daily chemicals, oil drilling, drilling working fluids, completion fluids, petrochemical dehydration fluids, early strength agents in the construction industry, coagulants for the production of coatings, latex coagulants in the rubber industry, additives in the paper industry and waste paper deinking, inorganic chemical raw materials and sulfate removers in the chemical industry.

Coagulant of sodium alginate, prevention and control of wheat, apple, cabbage and other rot and food preservatives, preparation of sodium metal and other sodium compounds, iron and steel heat treatment medium, etc. Salt also has a wide range of uses in water treatment, road snow removal, refrigeration and refrigeration, etc.

Before the industrial era, people referred to salt as salt for seasoning in life, not "salt" in chemical science today. However, in real life, a considerable number of people do not have a high level of education, and they cannot distinguish the substantive difference between "table salt" in life and "salt" in chemistry, so that there have been many incidents of accidental ingestion of toxic salts and mass poisoning.

Nitrite has strong reducibility, which can make the meat colorful, and some unscrupulous and ignorant businesses in life use industrial salt to marinate stale meat products, resulting in mass nitrite poisoning incidents, so"Industrial salts"It is often customary to refer specifically to nitrite. Long-term intake of nitrite also increases the risk of cancer, and industrial salt is strictly forbidden to eat.

Rise up industrial salt industry: industry: 1. The top of the tannery industry is treated with salt dry method and salting method for antiseptic treatment; 2. The top of the iron and steel industry is used as a heat treatment agent; 3. In the dye industry, it is used as a material for the production of caustic soda, soda ash, chlorine, etc.; 4. It is an analysis reagent for fluorine and silicate;

The uses of industrial salt include hydrogen production, hydrochloric acid, sodium hydroxide, chlorate, hypochlorite, bleaching powder, sodium metal, salting out soap, tanning, refrigerant carrier, medical, etc. Industrial salt is one of the most basic raw materials in the chemical industry, and its main components are sodium chloride, sodium nitrite, etc., which is known as the mother of the chemical industry. The main products of the basic chemical industry, such as hydrochloric acid, caustic soda, soda ash, ammonium chloride, etc., are mainly produced with industrial salt as raw materials.

Inspection rules: Products produced by the same production process and the same resources are regarded as a batch. All indicators in the test results should meet the requirements of the corresponding level of this standard, otherwise they should be downgraded; If an index does not meet the requirements of the lowest level of this standard, the non-conformity should be re-determined by taking a spare sample of the sample; If the inspection results still do not meet the requirements of the minimum hardship level of this standard, it will be judged that the batch of products is unqualified.

Industrial salt shall be inspected by the quality inspection department of the production unit or entrusted by a qualified quality inspection agency, and the product shall be accompanied by a certificate of conformity when leaving the factory, indicating the name, specification, production unit, production date, grade and number of this standard.

Precautions: Industrial salt can be packaged or bulk when leaving the factory. Products with packaging should indicate the product name, specification, trademark, grade, production unit and this standard number on the package.

It should be transported with a covering and should not be mixed with goods that can cause contamination of the product. The product should be stored to prevent pollution from dust and other sundries, and to prevent rain.
