About Technical salt (sodium chloride)
Technical salt is a natural mineral product, the main chemical element of which is sodium chloride (NaCl).
Technical salt is widely used in industry, utilities and other areas of human activity. It is used to create anti-icing agents, the preparation of drilling fluids, cleaning and softening of water, the production of caustic and chlorine, the manufacture of physiological solutions and pharmaceutical products.
