3), The usage of sodium metasilicate
1. metasilicate in the industrial field detergents, ceramics, electroplating, textile, printing and dyeing, paper, cement, concrete, refractories, oil and leather processing has a large number of applications
2. Application of a large amount of industry sort is: Ceramics, industrial cleaning, detergents, concrete, printing and dyeing, paper, cement, oil exploration, etc. will be applied to the detergent sodium metasilicate
3. In inorganic electrolytes, the active alkalinity and PH buffer highest index metasilicate, there is a strong wetting, emulsification and saponification role grease, with excellent performance in the removal of dispersed and suspended dirt aspects and to prevent dirt redeposition.
