Polyaluminium chloride, hu ua:PAC. Nws yog ib qho inorganic polymer coagulant, uas tuaj yeem muab faib ua cov khoom thiab cov kua hauv daim ntawv. Cov khoom yog muab faib ua tan, beige, golden daj thiab dawb raws li cov xim sib txawv, thiab cov kua yuav muaj xim tsis muaj xim thiab pob tshab, me ntsis daj, lub teeb daj mus rau daj xim av. Polyaluminium chlorides ntawm cov xim sib txawv kuj tseem txawv heev hauv daim ntawv thov thiab kev siv tshuab ntau lawm.
Txoj kev Dissolution ntawm polyaluminium chloride:
1. Dissolution piv. Lub dissolving piv ntawm polyaluminium chloride yog 5%, uas yog, 50g polyaluminium chloride yog ntxiv rau 1 kg ntawm dej rau dissolution. (Cov dej rau dissolving cov tshuaj yog kais dej los yog purified dej)
2. Lub sijhawm tawg. Lub sij hawm nplawm thiab yaj ntawm cov tshuaj yog 5-10min, thiab lub sij hawm dissolving sawv yog 0.8-1h.
3. Kev siv tshuaj. Qhov ntau npaum li cas ntawm tus neeg sawv cev no yog ntxiv raws li ib feem pua, thiab tus nqi tshwj xeeb yog txiav txim siab raws li qhov concentration ntawm cov dej phwj tuaj thiab cov qauv kev kho mob.
Kev ceev faj rau dissolving polyaluminium chloride (PAC):
1. Cov dej rau cov neeg ua kom yaj tus neeg sawv cev yog dej kais dej lossis dej ntshiab, thiab tsis tuaj yeem yaj nrog dej phwj lossis dej khib nyiab.
2. Txiav txim siab npaum li cas raws li koj qhov teeb meem tiag tiag.
