Sodium Aluminate (sodium Metaaluminate)
Kev piav qhia
Khoom siv sodium aluminate yog ib hom khoom alkaline muaj zog uas zoo li hmoov dawb lossis cov khoom me me, tsis muaj xim, tsis muaj ntxhiab thiab tsis saj, Tsis yooj yim hlawv thiab tsis tawg, Nws muaj kev yaj zoo thiab yooj yim yaj hauv dej, sai sai kom meej thiab yooj yim nqus cov dej noo thiab carbon dioxide hauv huab cua. Nws yooj yim rau precipitate aluminium hydroxide tom qab yaj hauv dej.

Cov yam ntxwv ntawm cov khoom
Txais yuav cov thev naus laus zis nrog cov cai tswjfwm kev txawj ntse ywj pheej thiab ua cov khoom tsim tawm nruj raws li cov qauv tsim nyog. Xaiv cov khoom zoo nrog kev ntshiab dua, cov khoom sib xws thiab xim ruaj khov. Sodium aluminate tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev siv alkali, thiab nws muab cov khoom siv aluminium oxide ua haujlwm siab. (Peb lub tuam txhab tuaj yeem tsim cov khoom lag luam nrog cov ntsiab lus tshwj xeeb raws li cov neeg siv khoom xav tau.)
