Industrial salt can be used to make chemicals. For example, sodium chloride can be used to make chemicals such as chlorine gas, sodium hydroxide, and hydrogen chloride.
Metallurgy: Industrial salt is mainly used in alkali, soap making industry and the production of chlorine gas, sodium hydroxide, but also widely used in metallurgy, leather, pharmaceutical industry and agriculture, animal husbandry and fishery.
Snow melting agent: can be used as snow melting agent, can also be used in sewage treatment.
Dye industry: The common dye raw materials in industry are directly produced by industrial salt, and hydrochloric acid is also a chemical product made of deep processing. Almost every step of the dye production process consumes a certain amount of salt. It is also widely used in water treatment, snow melting agent, refrigeration and other fields.
Road snow removal: Industrial salt Salt also has a wide range of uses in water treatment, road snow removal, refrigeration and refrigeration.
Before the industrial era, people said salt, specifically refers to the salt used in life, rather than the "salt" in chemical science. However, in real life, a considerable number of people's cultural level is not too high, can not distinguish the difference between the "salt" in life and the "salt" in chemistry, and so many cases of accidental eating of toxic salt, the occurrence of mass poisoning events.
Nitrite is strong in reducing, can make the flesh color bright, some bad and ignorant businesses in life with industrial salt pickled meat products, resulting in mass nitrite poisoning events, so "industrial salt" is usually used to refer to nitrite. Long-term intake of nitrite also increases the risk of cancer, and industrial salt is strictly prohibited.
