Caustic soda pearl is a solid caustic soda

Caustic soda pearls can be divided into coarse-grained alkali and fine-grained alkali according to the particle size. The particle diameter of the fine-grained alkali is about 0.7mm, and the shape is very similar to washing powder.

In solid alkali, caustic soda flakes and pearls are common and used solid alkalis, and pearls are better than caustic soda flakes, but relatively, pearls are more difficult and complicated to make than caustic soda, so , the price of pearls is naturally higher than that of flakes.

Pearl is mainly used as a chemical raw material, an important basic chemical raw material, and has a wide range of uses. In the chemical industry, it is used to manufacture formic acid, oxalic acid, borax, phenol, sodium cyanide, soap, synthetic fatty acid, synthetic detergent, etc. In the textile printing and dyeing industry, it is used as a solvent for cotton desizing agent, scouring agent, mercerizing agent, vat dye and Haichang blue dye. Used in the smelting industry to manufacture aluminum hydroxide, alumina and metal surface treatment agents. In the instrument industry, it is used as an acid neutralizer, decolorizer, and deodorizer. Adhesive industry is used as starch gelatinizer and neutralizer. In addition, it is widely used in enamel, medicine, cosmetics, leather, paint, pesticides, glass and other industries.

In most industrial aspects, pearls are superior to other solid alkalis such as flakes, so they are widely welcomed by industrial manufacturing, but at the same time, the production process of pearls is also difficult to manufacture other solid alkalis such as flakes.
