Sodium metasilicate i ityiwa silicic acid, kwaye ifomula yayo ezinto angabhalwa Na2SiO3 · nH2O. Sodium metasilicate yi crystal eliphantsi beemolekyuli eziqulunqwe indlela wobushushu lwesiseko bubble eqhelekileyo kunye icaustic
ntonye: Isodiyam metasilicate pentahydrate
CAS no: 6834-92-0
ifomula eziphilayo: Na2SiO3 .5H2O
ubunzima Ezinto: M = 122,066
Inkangeleko: white akhazimlayo umgubo
Isodiyam metasilicate pentahydrate awana kakhulu, ukuba amandla olomeleleyo ukucoca, kumthamo kunye ukuthambisa, counteracting Ungcoliseko asidi, emulsifying amafutha neoli, deflocculating ukuya ezingaphiliyo. It buyisela STPP ukuba kusetyenziswa ukulungiselela ukwenziwa iisepha esebenzayo irusi remover metal, ukunciphisa ungcoliseko lokusingqongileyo, ukuvimbela umhlwa ngenxa metal (zinc, i-aluminiyamu, njalo njalo). Ngoko ke, sodium metasilicate pentahydrate isetyenziswa ngokubanzi eyimveliso iindidi iisepha, isetyenziswa irusi remover metal, ukugaya izixhobo ngenxa iiseramikhi, arhente deinking iphepha, ukudaya ngokwemfundo kwanancedisayo yoshicilelo ngenxa yokubulala leoli noshishino lwempahla eyolukiweyo, kwaye usetyenziswa ekrwada ekufanisweni arhente flameproofing, iarhente ulondolozo zeplastiki, i-arhente zokugcinwa kwamanzi, njl Used in arhente zamanzi ukunciphisa, sodium metasilicate pentahydrate uyakwazi ukuhlanganisa hydrones ngaphezulu ukwenza isiphumo ukunciphisa ubumanzi engcono
