Sodium Chloride

short description:

Its source is mainly seawater, which is the main component of salt. Soluble in water, glycerin, slightly soluble in ethanol (alcohol), liquid ammonia; Insoluble in concentrated hydrochloric acid. Impure sodium chloride is deliquescent in air. The stability is relatively good, its aqueous solution is neutral, and the industry generally uses the method of electrolytic saturated sodium chloride solution to produce hydrogen, chlorine and caustic soda (sodium hydroxide) and other chemical products (generally known as chlor-alkali industry) can also be used for ore smelting (electrolytic molten sodium chloride crystals to produce active sodium metal).

Product Usage

Detergent addition

In soap making and synthetic detergents, salt is often added in order to maintain the appropriate viscosity of the solution. Due to the action of sodium ions in salt, the viscosity of saponification liquid can be reduced, so that the chemical reaction of soap and other detergents can be carried out normally. In order to achieve sufficient concentration of fatty acid sodium in the solution, it is also necessary to add solid salt or concentrated brine, salt out, and extract glycerol.

Papermaking

Industrial salt is mainly used in the paper industry for pulp and bleaching. With the improvement of environmental awareness, the application prospect of environmentally friendly salt in the paper industry is also very broad.

Glass industry

In order to eliminate the bubbles in the glass liquid when melting glass, a certain amount of clarifying agent must be added, and salt is also the composition of the commonly used clarifying agent, and the amount of salt is about 1% of the glass melt.

Metallurgical industry

Salt is used in the metallurgical industry as a chlorination roasting agent and quenching agent, and also as a desulfurizer and clarifying agent for the treatment of metal ores. Steel products and steel rolled products immersed in salt solution can harden their surface and remove the oxide film. Salt chemical products are used in the pickling of strip steel and stainless steel, aluminum smelting, electrolysis of sodium metal and other cobaking agents, and refractory materials in smelting need salt chemical products.

Printing and dyeing additive

Industrial salts can be used as dye promoters when dyeing cotton fibers with direct dyes, vulcanized dyes, VAT dyes, reactive dyes and soluble VAT dyes, which can adjust the dyeing rate of dyes on fibers.
