Aluminium Sulphate hauv kev kho dej
Lub ntsiab nta
Kev ua tau zoo ntawm coagulation zoo: Aluminium sulfate tuaj yeem tsim cov colloidal precipitate sai sai, ua kom cov tshuaj tshem tawm sai sai hauv dej, yog li txhim kho cov dej zoo.
Kev siv dav dav: Haum rau txhua hom dej hauv lub cev, suav nrog dej kais dej, dej khib nyiab, dej hauv pas dej, thiab lwm yam, nrog rau kev siv tau zoo thiab siv tau ntau yam.
PH hloov ua haujlwm: Nws tuaj yeem kho tus nqi PH ntawm cov dej hauv qee qhov ntau, uas pab txhim kho kev ruaj ntseg thiab siv tau ntawm cov dej.
Non-toxic thiab environmentally friendly: Cov khoom nws tus kheej yog non-toxic thiab harmless, environmentally friendly thiab ua raws li cov qauv kev tiv thaiv ib puag ncig.

Yuav siv li cas
Kev kho dej:Ntxiv ib qho tsim nyog ntawm txhuas sulfate rau hauv dej, do tusyees, thiab tshem tawm cov khib nyiab los ntawm nag lossis daus thiab pom.
Paper manufacturing:Ntxiv ib qho nyiaj tsim nyog ntawm txhuas sulfate rau lub pulp, do tusyees, thiab ua tiav nrog cov txheej txheem papermaking.
Tawv ua:Aluminium sulfate daws yog siv rau hauv cov txheej txheem tanning ntawm tawv raws li cov txheej txheem tshwj xeeb.
Kev lag luam zaub mov:Raws li cov kev xav tau ntawm cov txheej txheem tsim khoom noj, ntxiv ib qho tsim nyog ntawm aluminium sulfate rau cov khoom noj.
Ntim Specifications
Cov ntim ntim ntau suav nrog 25kg / hnab, 50kg / hnab, thiab lwm yam, uas tuaj yeem ua raws li cov neeg siv khoom xav tau.
Cia thiab ceev faj
Cov khoom yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav kom deb ntawm lub hnub ncaj qha.
Tsis txhob sib xyaw nrog cov tshuaj acidic kom tsis txhob cuam tshuam cov khoom lag luam.
