Aluminium sulfate, nrog rau cov tshuaj formula Al₂(SO₄)₃, yog ib qho tseem ceeb dej purifier thiab daim ntawv sizing tus neeg saib xyuas. Nws cov qauv khoom zoo suav nrog GB31060-2014 Aluminium Sulfate rau Cov Tshuaj Kho Dej thiab HG / T2225-2018 Muaj Aluminium Sulfate. Cov neeg siv khoom lag luam feem ntau xav tau cov khoom lag luam nrog alumina cov ntsiab lus ntau dua lossis sib npaug li 16.00% thiab cov khoom ua kua nrog cov ntsiab lus alumina ntawm Ntau dua lossis sib npaug li 7.50%.
Aluminium sulfate yog tsim los ntawm ntau yam txheej txheem, nrog rau cov txheej txheem bauxite, txheej txheem txhuas hydroxide, txheej txheem kaolin, txheej txheem alunite, thiab lwm yam txheej txheem uas muaj txhuas-cov ntaub ntawv. Tam sim no, cov txheej txheem bauxite thiab aluminium hydroxide txheej txheem yog qhov nthuav dav tshaj plaws.
Cov txheej txheem bauxite: Bauxite reacts nrog sulfuric acid. Cov kua tshuaj tiv thaiv tau dhau los ua cov khoom sib cais- kua sib cais los tsim cov khoom ua kua. Cov khoom ua kua yog evaporated, concentrated, txias, crystallized, thiab ces crushed thiab sieved los ua ib tug khoom khoom.
Cov txheej txheem aluminium hydroxide: Aluminium hydroxide reacts nrog sulfuric acid, txias, solidifies, thiab ces yog crushed thiab sieved los tsim cov aluminium sulfate tiav.
Aluminium sulfate muaj ntau yam kev siv, feem ntau hauv kev ua kom huv ntawm cov dej haus thiab cov dej khib nyiab hauv kev lag luam, pulp sizing nyob rau hauv daim ntawv kev lag luam, pob zeb accelerator, clarifier nyob rau hauv cov roj thiab roj kev lag luam, deodorant thiab decolorant nyob rau hauv cov roj av kev lag luam, tawv tanning, pigment manufacturing, demoulding ntawm refractory cov ntaub ntawv, ua npuas ncauj extinguishing agents, thiab lwm yam.
