caustic soda pearl

Caustic soda pearl is white spherical grain which is one of the basic chemical materials, and the high purity caustic soda pearl is the upgrade product of the solid caustic soda pearl. 1. Main application scope: It is used in synthetical detergence, textile, paper making, printing, dyeing, soap; the original dye, the dissolving agent of the dye which is not soluble in azote; medicine, food, rayon, petroleum and war industry etc. 2. Special feature: High purity (the content of NaOH can reach 99%), even particles, few impurity, good fluidity, easily to be matched in use with others. 3. Processing technic: The company introduced the advanced pelleting technique, the equipments of the nickel pipe and stainless steel pipe, which is lower in the content of the heavy metal and other impurity, we take the 50% ionic membrane liquid caustic soda pearl as material, every part of the workshop should keep clean to prevent the dust and the residual solid caustic soda pearl from entering the equipments, thus to produce the grainy caustic soda pearl with high quality, even particles, stable quality without powder.
