Sodium Aluminate (sodium Metaaluminate)
Kev piav qhia
Khoom Sodium aluminate yog ib hom khoom muaj zog alkaline zoo li cov hmoov dawb lossis zoo granular, tsis muaj xim, tsis muaj ntxhiab thiab saj-tsawg, Tsis yog nplaim taws thiab tsis tawg, Nws muaj cov solubility zoo thiab yooj yim soluble hauv dej, ceev kom meej thiab yooj yim rau nqus noo noo thiab carbon dioxide hauv huab cua. Nws yog ib qho yooj yim rau precipitate aluminium hydroxide tom qab dissolution hauv dej.

Cov yam ntxwv ntawm cov khoom
Txais siv thev naus laus zis nrog kev ywj pheej ntawm cov cuab yeej cuab tam kev txawj ntse thiab ua kom nruj ntau lawm raws li cov qauv tsim nyog. Xaiv cov khoom zoo nrog cov purity siab dua, cov khoom sib xws thiab cov xim ruaj khov. Sodium aluminate tuaj yeem ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv thaj chaw ntawm alkali daim ntaub ntawv, thiab nws muab lub hauv paus ntawm kev ua haujlwm siab aluminium oxide. (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.)
Daim ntawv thov teb
Foaming-inhibiting Cheebtsam nyob rau hauv high-alkaline tu neeg ua hauj lwm rau npias fwj, steel, thiab lwm yam. tsev ntxhua khaub ncaws ntxhua khaub ncaws, ntxhua khaub ncaws hmoov, los yog ua ke nrog cov tshuaj ntxuav, granular insecticides qhuav-mixed mortar, hmoov coatings, siliceous av nkos, thiab drilling zoo cementing industries mortaring, thiab lwm yam. adhesives, tshuaj ntxuav, thiab synthesis ntawm cov khoom siv tshuaj tua kab.
