caustic soda flake

The chemical name is sodium hydroxide, which is a basic chemical raw material. The pure product is a colorless transparent crystal. Pure solid flake alkali is white and semi transparent, with block, sheet, rod, and granular shapes, and is brittle in texture; Pure liquid is a colorless and transparent liquid.
Properties of flake alkali: Solid flake alkali has strong hygroscopicity, is easily soluble in water, releases heat when dissolved, and the aqueous solution is alkaline with a smooth feeling; Dissolve in ethanol and glycerol; Insoluble in acetone, highly corrosive, and has a corrosive effect on fibers, skin, glass, ceramics, etc. Reacting with metallic aluminum and zinc, non-metallic boron and silicon to release hydrogen; Disputation reaction occurs with halogens such as chlorine, bromine, iodine, etc; Neutralizes with acids to produce salts and water.
Application scope of caustic soda flakes:
1. Used for the production of paper and cellulose pulp;
2. Used for the production of soap, synthetic detergents, synthetic fatty acids, and the refining of animal and vegetable fats.
3. In the textile printing and dyeing industry, it is used as a cotton fabric desizing agent, refining agent, and silk finishing agent.
4. The chemical industry is used to produce borax, sodium cyanide, oxalic acid, phenol, etc.
5. The petroleum industry is used to refine petroleum products and in drilling mud for oil fields. It is also used for surface treatment in the production of alumina, metallic zinc, and metallic copper, as well as in glass, enamel, leather, medicine, dyes, and pesticides.
6. Food grade products are used in the food industry as acid neutralizers, peelers for citrus, peach, and other fruits, detergents for empty bottles, cans, and other containers, as well as decolorizers and deodorizers.
7. It can also be used as an alkaline desiccant.
