Sodium hydroxide has strong alkalinity and strong corrosiveness. It can be used as acid neutralizer, matching masking agent, precipitant, precipitation masking agent, color developing agent, saponification agent, peeling agent, detergent, etc.
Sodium hydroxide has strong alkalinity and strong hygroscopicity. It is easy to dissolve in water and gives off heat when dissolving. The aqueous solution is alkaline and greasy. It is highly corrosive and corrosive to fibers, skin, glass and ceramics. It reacts with aluminum and zinc, non-metallic boron and silicon to give out hydrogen, disproportionation with halogen such as chlorine, bromine and iodine, neutralizing with acids to form salt and water.

Application
Sodium hydroxide is mainly used in papermaking, cellulose pulp production, soap, synthetic detergent, synthetic fatty acid production and animal and vegetable oil refining. It is used as desizing agent, scouring agent and mercerizing agent in textile printing and dyeing industry. Chemical industry is used to produce borax, sodium cyanide, formic acid, oxalic acid, phenol, etc. Petroleum industry is used for refining petroleum products and drilling mud in oil field. It is also used in surface treatment of alumina, zinc and copper, glass, enamel, leather, medicine, dye and pesticide. Food grade products are used in food industry as acid neutralizer, peeling agent for oranges and peaches, detergent for empty bottles and cans, decolorizer and deodorizer.
