Main Application Fields
Kev kho dej:Siv los ntxuav cov kais dej thiab cov dej khib nyiab, tshem tawm cov khib nyiab, xim thiab impurities, thiab txhim kho cov dej zoo.
Paper manufacturing:Siv ua muab tub lim thiab gelling tus neeg sawv cev los txhim kho lub zog thiab gloss ntawm daim ntawv.
Tawv ua:Siv nyob rau hauv cov txheej txheem tanning ntawm tawv los txhim kho nws kev ntxhib los mos thiab xim.
Kev lag luam zaub mov:Raws li ib feem ntawm coagulants thiab flavoring agents, nws yog dav siv nyob rau hauv cov khoom noj khoom haus.
Pharmaceutical kev lag luam:Siv nyob rau hauv qee qhov kev tshwm sim thaum lub sijhawm npaj thiab tsim cov tshuaj.
Cia thiab ceev faj
Aluminium Sulfate yuav tsum muab cia rau hauv qhov chaw txias, qhuav kom deb ntawm tshav ntuj ncaj qha.
Tsis txhob sib xyaw nrog cov tshuaj acidic kom tsis txhob cuam tshuam cov khoom lag luam.
