Sodium metasilicate mao ang usa ka asin sa silicic acid, ug ang mga molekula pormula mahimong gisulat ingon nga Na2SiO3 · nH2O. Sodium metasilicate mao ang usa ka ubos nga molecular kristal nga giandam sa kainit reaksiyon sa usa ka komon nga bula base sa caustic soda
kahulogan: sodium metasilicate pentahydrate
CAS wala: 6834-92-0
sa molekula pormula: Na2SiO3 .5H2O
Sa molekula nga timbang: M = 122,066
Panagway: puti nga kristal powder
Sodium metasilicate pentahydrate is strongly alkaline, having strong capacity of cleaning, buffering and softening, counteracting acidic contamination, emulsifying fat and oil, deflocculating to inorganic. It can replace STPP to be used for the manufacture of effective detergents and rust remover for metal, reducing environmental pollution, preventing corrosion for metal (zinc, aluminum, etc.). Therefore, sodium metasilicate pentahydrate is widely used for the manufacture of a variety of detergents, used as rust remover for metal, grinding aids for ceramics, deinking agent for paper, dyeing and printing auxiliary for removing oil in textile industry, and also used as the raw material for flameproofing agent, plastic maintenance agent, water retention agent, etc. Used in water reducing agents, sodium metasilicate pentahydrate is able to integrate more hydrones to make better moisture absorption effect
