The difference between sodium silicate and sodium metasilicate
The saponin is actually sodium silicate. You may have heard of sodium metasilicate. Sodium metasilicate and sodium silicate are not the same kind of materials. They each have their own characteristics and uses. What are the main differences between the two? Here is a brief introduction to Laizhou Welfare Soap Alkali Co., Ltd.
Properties: The saponin is a colorless, cyan or brown solid or viscous liquid. Sodium metasilicate is a low molecular crystal prepared by the thermal reaction of a common bubble base with caustic soda. The products are anhydrous, pentahydrate and hexahydrate.
Production process: The production process of saponin is dry and wet, dry production of solid saponin, and then dissolved into liquid alkaloids of the required specifications. Sodium metasilicate has different processes due to different classifications. The anhydrous sodium metasilicate loses the glassy acicular crystals when it is slowly heated at about 55 °C. Pentahydrate sodium metasilicate, monoclinic columnar crystal, melting point 72.2 ° C, soluble in water and dilute lye. Nine water, orthorhombic crystal, melting point 40 ~ 48 ° C, boiling point 100 ° C, and remove 6 crystal water. Soluble in water and dilute lye. After the water glass is reacted with the caustic soda solution, it is concentrated, crystallized, separated, and dried.
Function: The saponin has high adhesion and strength, good acid resistance and good heat resistance. Sodium metasilicate has the highest active alkalinity and PH buffer index, and has strong wetting, emulsifying and saponifying oils. It has excellent performance in removing, dispersing and suspending dirt, and can prevent redeposition of dirt.
Uses: The saponin is mainly used in chemical systems, light industry, textile industry, machinery industry, construction industry and agriculture. In addition, saponin is widely used as binder in cardboard carton. Sodium metasilicate has a large number of applications in the industrial fields of detergent, ceramics, electroplating, textile, printing and dyeing, paper making, cement, concrete, refractory, grease and leather processing.
