Polyaluminium chloride (aluminium chlorohydrate) kuj hu ua PAC, yog siv rau hauv deodorants thiab ua coagulant hauv dej purification. Qhov kev sib xyaw no nyiam nyob rau qee kis vim nws cov nqi siab, uas ua rau nws muaj txiaj ntsig zoo ntawm kev tsis ruaj khov thiab tshem tawm cov ntaub ntawv tshem tawm dua li lwm cov ntsev txhuas.
| Cov khoom | Guarantee Tus nqi | Tus nqi | |
| Alumina (Al2O3) Cov ntsiab lus% | Ntau tshaj los yog sib npaug rau 30 | 30.15 | |
| Basicity % | 70-90 | 83.9 | |
| Dej Insoluble% | Tsawg dua los yog sib npaug li 1.5 | 0.3 | |
| Tus nqi PH (1% daws) | 3.5-5.0 | 3.8 | |

Qhov loj ntawm sulfide ions tam sim no nyob rau hauv cov dej phwj tuaj tsis yog tsuas yog tsim kev puas tsuaj rau ib puag ncig ib puag ncig, tab sis kuj tuaj yeem ua rau muaj kev cuam tshuam hauv zos thiab kev ntxhov siab corrosion ntawm cov khoom siv hlau. Siv polyaluminium chloride rau desulfurization hauv oilfield kev kho dej khib nyiab tuaj yeem ua tiav cov txiaj ntsig pom tseeb. Polyaluminium chloride muaj pH dav, tus nqi qis, thiab kev nyab xeeb zoo. Electrochemical txoj kev yog siv los oxidize sulfur ions rau hauv cov hlau sulfur, thiab tom qab ntawd polyaluminium chloride yog siv los ua flocculant rau desulfurize thiab kho cov dej khib nyiab.
