Polyaluminium chloride (tseem hu ua PAC, polyaluminum, polyaluminum, polyaluminum chloride) hlau yog kev cog tshuaj nplua nrawm, txawm nyob hauv tsev lossis txawv teb chaws. Nws yog cov flocculant siv dej huv, thiab nws cov kev tshawb fawb thiab kev txhim kho yog qhov tseem ceeb rau kev kho dej thiab tshuaj lom neeg zoo. Tam sim no muaj ob txoj lus qhia hauv kev tsim khoom khoom. Qhov thib ib yog los tsim cov ntaub ntawv tshiab los npaj polyaluminum ferric chlape cov khoom, siv txhuas tshauv thiab txhuas slag los npaj polyaluminum ferricide khoom. Tus txheej txheem yog qhov yooj yim thiab kev txhim kho thaum ntxov yog nrawm. Nyob rau hauv xyoo tas los, kev lag luam tsim khoom siv tau siv (kev tshawb fawb ntawm ya tshauv thiab thee gangue raws li cov ntaub ntawv ntim nyiaj yuav tsum nyiam xim.
Kev siv cov khib nyiab ua cov khoom siv raw los tsim polyaluminum ferric chloride tsis xwb txuag cov khoom siv ntawm cov khib nyiab. Nws yog qhov kev tshawb fawb tshawb fawb hauv kev ua lag luam. Lwm qhov kev taw qhia yog polyaluminium ferric chloride thiab inorganic kev tshawb fawb txog cov ntawv sib xyaw lossis daim ntawv thov cov tshuaj polymer flocculants. Compound los yog cov neeg sawv cev sib xyaw tuaj yeem ua rau cov tsis muaj peev xwm ntawm ib tus mob flocculant, muaj ntau cov kev siv kabmob ion, tuaj yeem txhim kho cov txiaj ntsig flocculation. Poly Aluminium chloride polyaluminum tshuaj chloride yog ib qho inorganic polymer coagulant. Nws ua cov dej hauv cov roj ntsha uas muaj qhov hnyav dua thiab cov txiaj ntsig ntau dua vim yog cov kab mob hniav loj ntawm hydroxide ions thiab polymerizes ntawm polyvalent anions. Cov yam ntxwv ntawm cov tshuaj kho mob yog feem ntau txiav txim los ntawm tus ua haujlwm ntawm lub siab atomizer. Ib qho ntxiv, cov txheej txheem sib txawv ntawm PAC tam sim no feem ntau yog cov muaj kuab paug loj, cov khoom lag luam tsis muaj peev xwm siv thiab tsis khov. Kev txhim kho ntawm kev ua haujlwm siab txuas ntxiv ua cov txheej txheem txuas ntxiv yuav ua qhov kub rau kev tshawb fawb ntau lawm hauv kuv lub tebchaws. Daim ntawv thov tseem ceeb ntawm Polyaluminium Ferric chloride hauv Suav teb hauv cov teb ntawm kev lag luam dej thiab cov khoom noj ntawm ob daim ntawv sib tw rau kwv yees li 70% ntawm tag nrho cov kev noj.
Qhov kev faib ua feem siv hauv kev lag luam lim dej phuafification rau ntau tshaj 40%; Qhov kev faib ua feem siv hauv cov kais dej huv si thiab kev ua dej phwj tuaj thiab kev lim dej hauv tsev yog li 30%; Muaj Kev Nyab Xeeb Siraculating thiab Dej Pas Dej Digacoir Limification Account rau 20%; lwm tus account rau 10%. Nrog rau lub teb chaws txoj kev txhim kho ntxiv ntawm cov kev tiv thaiv ib puag ncig ib puag ncig, tus nqi siv hauv kev kho kom muaj dej khib nyiab yuav txuas ntxiv ntxiv.
