Aluminium sulfate yog ib qho inorganic khoom uas yooj yim soluble hauv dej, yuav luag insoluble hauv ethanol, thiab cov tshuaj yog acidic. Aluminium sulfate yog siv los ua tus neeg saib xyuas dephosphorizing, defluorinating tus neeg sawv cev, decolorizing tus neeg sawv cev, decolorizing thiab deodorizing roj av khib nyiab, acid hloov ntawm alkaline cov dej khib nyiab, thiab flotation ntawm cov dej khib nyiab hauv cov dej khib nyiab sib sib zog nqus.
Lub luag haujlwm ntawm aluminium sulfate hauv kev kho dej phwj tuaj
Hauv kev kho dej phwj tuaj, aluminium sulfate yog siv los ua coagulant. Cov txhuas oxide thiab txhuas ions tsim tom qab yaj hauv dej, qhov zoo ntawm txhuas ions hauv cov khoom siv hydrolysis yuav sib tsoo thiab nyiam nrog cov khoom me me uas tsis zoo nrog cov ions tsis zoo hauv dej, tsim cov nqi nruab nrab, tshem tawm cov nqi ntawm qhov chaw. tshem tawm cov teeb meem, tawg tawm ntawm lub hauv paus ntsiab lus ntawm kev sib nrig sib repulsion ntawm zoo li tsub, thiab ces sai sai condensing ua ke los tsim particles loj tshaj lub buoyancy ntawm dej, thiab nyob rau hauv qab ntawm dej.
Los ntawm kev sib sau cov impurities ua ke los tsim cov khoom loj, nws yooj yim rau lim thiab tshem tawm. Li no txhim kho qhov pom tseeb ntawm dej. Nyob rau hauv cov txheej txheem no, txhuas sulfate yuav tsum tau ntxiv ib tug tsim nyog tus nqi ntawm sodium hydroxide rau cov dej los kho tus nqi pH kom ntseeg tau qhov zoo tshaj plaws coagulation nyhuv.
