Sodium nitrate is the raw material for making potassium nitrate, mine explosives, picric acid, dyes, etc. . A nitrating agent used in the manufacture of dye intermediates. The glass industry is used as defoamer, decolorizer, clarifier and oxidation flux in the production of various glasses and their products. Enamel industry as an oxidant and flux, for the preparation of enamel powder. The machinery industry uses it as a cleaning agent for metals and as a Ferrous agent. The metallurgical industry is used as a heat treatment agent for steel making and aluminium alloys. An accelerant used in light industry to make cigarettes. The pharmaceutical industry uses penicillin as a medium. The chemical fertilizer industry is used as a quick-acting fertilizer for acid soils, especially for root crops such as beets and radishes. It is also used as a decolorizing agent for molten caustic soda. High purity analytical reagents, spectral reagents, oxidants, also used in the synthesis of dyes and explosives and fireworks manufacturing. Nitrates all have the function of early strength, especially at low and negative temperature as early strength and antifreeze. Used in toothpaste as corrosion inhibitor,desensitizer, to prevent dentin allergy. Sodium nitrate is mainly used as corrosion inhibitor and embrittlement inhibitor in water treatment.
Operating notes: closed operation, strengthen ventilation, operators must undergo special training, strictly abide by the operating procedures, the operator is recommended to wear self-suction filter dust-proof mouth, wear chemical safety protective glasses, wear a polyethylene suit and neoprene gloves. Keep away from kindling, heat source, no smoking in the workplace, keep away from inflammable and combustible materials. Avoid producing dust. Avoid contact with reducing agents, reactive metal powder, acids, to be handled by light loading and unloading, to prevent packaging and container damage. Equipped with the corresponding variety and quantity of fire-fighting equipment and leakage emergency treatment equipment. Emptied containers may leave harmful residues.
Storage considerations; store in a cool, ventilated warehouse. Keep away from fire, heat source, storage temperature not more than 30 ° C, relative humidity not more than 80% , should be stored separately with reducing agent, active metal powder, acid, combustible, avoid mixed storage, storage areas should be equipped with appropriate materials to contain leakage.
