Sodium metasilicate ay isang asin ng silisik acid, at ang molecular formula ay maaaring isulat bialng Na2SiO3 · nH2O. Sodium metasilicate ay isang mababang molekular kristal na inihanda ng thermal reaksyon ng isang pangkaraniwang bubble base na may sosa
Singkahulugan: Sodium metasilicate pentahydrate
CAS no: 6834-92-0
Molekular formula: Na2SiO3 .5H2O
Molekular timbang: M = 122.066
Itsura: puting kristal na 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
