Sodium metasilicate kuyinto usawoti silicic acid, futhi ifomula kwama-molecule ayo singatlolwa bunjesi Na2SiO3 · nH2O. Sodium metasilicate kuyinto crystal ongaphakeme yamangqamuzana okulungiselelwe ukusabela ezishisayo lobufanako bubble isizinda nge caustic soda
Umqondofana: Sodium metasilicate pentahydrate
CAS kungekho: 6834-92-0
ifomula Yamamolekhula: Na2SiO3.5H2O
isisindo Yamamolekhula: M = 122,066
Ukubukeka: crystal ezimhlophe powder
Sodium metasilicate pentahydrate asivumelani ngokuqinile ane-alikhali, kokuba umthamo enamandla yokuhlanza, kokubhafa futhi akuthanjiswanga, UKUPHEBEZA ukungcoliswa esidi, emulsifying amafutha namafutha, deflocculating ukuze wezinto ezingaphili. Kungaba esikhundleni STPP okumele asetshenziswe womshini izihlanzi ngempumelelo nokugqwala remover metal, ekunciphiseni ukungcoliswa kwemvelo, ekuvimbeleni ukugqwala ngoba metal (zinc, aluminium, njll). Ngakho-ke, i-sodium metasilicate pentahydrate kabanzi womshini ezihlukahlukene insipho esetshenziswa njengoba nokugqwala remover metal, ukugaya nezinsiza ukuze izinto ezenziwe ngobumba, deinking ejenti ukuze sithole iphepha, ukudaya nowokunyathelisa asizayo kokukhipha amafutha yendwangu umkhakha, futhi esetshenziswa njengoba impahla eluhlaza for ejenti flameproofing, plastic yesondlo ejenti, amanzi nokugcinwa ejenti, njll Asetshenziswa amanzi ekunciphiseni ejenti, sodium metasilicate pentahydrate uyakwazi ukuhlanganisa hydrones ngaphezulu ukwenza umswakama kangcono ukumuncwa umphumela
