Fengbai - Caustic Soda Pearls/Flakes
Caustic soda, also called sodium hydroxide, is a strong caustic alkali, generally white translucent sheet solid, soluble in water (heat release when dissolved in water) and forms an alkaline solution. It is deliquescent, easy to absorb water vapor and carbon dioxide in the air. Caustic soda in water treatment can be used as an alkaline cleaner, soluble in ethanol and glycerin, insoluble in propanol, ether. It also corrodes carbon and sodium at high temperatures. And it has a disproportionation reaction with chlorine, bromine, iodine, and other halogens. It forms salt and water when neutralizing with acids.

Three Common Types of Sodium Hydroxide
Caustic Soda Flakes
Caustic soda flakes is flaky white translucent solid in appearance, which is obtained by evaporating liquid caustic soda. The molten salt method is one of the methods for producing sodium hydroxide flakes. The lye is concentrated from 32% to 61% in the falling film evaporator. The heating source adopts medium pressure steam and secondary steam, and evaporates under vacuum. The 61% lye is then passed through the falling film concentrator, using molten salt as the heat carrier, the lye is concentrated into molten alkali under normal pressure. Then the caustic soda flakes are made by the flake alkali machine. In addition to water treatment fields, sodium hydroxide flakes are widely used in the light textile industry, such as papermaking, synthetic detergent and soap, viscose fiber, rayon and cotton fabric. Also be used in pesticides, dyes, rubber and chemical industries, petroleum drilling, petroleum oil refining and tar refining, as well as defense industry, machinery industry, wood processing, metallurgical industry and urban construction.
Caustic Soda Pearls
Caustic soda pearls, one type of solid caustic soda, is granular in appearance. According to the particle size, it can be divided into coarse-grained and particulate sodium hydroxide. The particle size of the particulate granular is about 0.7mm with the shape similar to washing powder. It has all the chemical properties of sodium hydroxide. When placed in the air, it will absorb moisture and deliquescence, react with carbon dioxide to deteriorate. The packaging requires drying and sealing. Generally, 25kg three-layer plastic woven bags are used to package granular caustic soda.
In most industrial fields, caustic soda pearls have better performance than caustic soda flakes and other solid sodium hydroxide. So it is widely welcomed by industrial manufacturing. At the same time, the production process of sodium hydroxide pearls is more difficult and complicated. Of course, the price is generally higher than that of the flake type.
Caustic Soda Liquid
Caustic soda lye is pure liquid caustic soda, which is colorless and transparent. Industrial grade mostly contain impurities, mainly sodium chloride and sodium carbonate, and sometimes a small amount of iron oxide. When dissolved into concentrated liquid caustic soda, most of the impurities will float to surface and can be separated and removed. In the chemical industry, it is used to manufacture formic acid, oxalic acid, borax, phenol, sodium cyanide, as well as soap, synthetic fatty acid and synthetic detergent. In textile printing and dyeing industry, it is used as a solvent for cotton cloth desizing agent scouring agent, mercerizing agent and vat dye. In the smelting industry, it can be used to manufacture aluminum hydroxide, aluminum oxide and metal surface treatment agents. In instrument industry, it is used as an acid neutralizer, decolorizer and deodorizing agent. In adhesive industry, it is used as starch gelatinizer and neutralizer. In addition, it is widely used in enamel, medicine, cosmetics, tanning, paint, pesticide, glass and other industries. We can supply the purity of 32%/50% caustic soda liquid with the package of 20L/25L/30L/220L drum and 1000L IBC drum.
Sodium hydroxide uses in making soap, printing and dyeing, textile, papermaking, refined petroleum, metallurgy, and other chemical industries because of its strong alkalinity. In addition, the production of dyes, plastics, and preparation of borax, manganate, phosphate, etc. also requires the use of a large amount of caustic soda.
