Product Description
Caustic Soda in Pearl is a solid caustic soda, grain of alkali according to the particle size can be divided into coarse grained alkali, particles, alkali particles in alkali grains in shape is like washing powder. In solid alkali, slice alkali and grain of alkali is most common and USES a solid base, while more than slice alkali grain alkali with some, but relatively grain of alkali than slice production process more difficult, dwell therein more complex, therefore, grain price also natural higher alkali slice alkali. Grain of alkali is solid naoh, with sodium hydroxide all chemical properties, solid alkali ChaoXie and extremely easily with carbon dioxide response, so solid alkali preservation generally need absolute dry and seal. In the packing for the same dry, sealed packaging, domestic generally USES the 25KG three layers of plastic woven bags grain of alkali.
