Polyaluminum chloride ili ndi ma adsorption, condensation, mvula ndi zina zomwe zimapangitsa kuti ikhale yolimba, yowononga, monga momwe imatayikira pakhungu mwangozi kuti isambidwe nthawi yomweyo. Ogwira ntchito opanga ayenera kuvala ma ovalolo, masks, magolovesi, kuvala nsapato za rabara. Polyaluminum chloride ili ndi ubwino wokhala ndi kuuma bwino kwa spray, malo otakata a madzi, kuthamanga kwa hydrolysis mwachangu, mphamvu yamphamvu ya ma adsorption, mapangidwe akulu a alum, mvula yachangu, kutayikira pang'ono kwa madzi komanso magwiridwe antchito abwino a kusowa madzi m'thupi. Zinthu zoumitsira spray zimatha kuonetsetsa kuti zili bwino, kuchepetsa ngozi zamadzi, madzi akumwa kwa okhalamo ndi otetezeka komanso odalirika. Chifukwa chake, polyaluminum chloride, yomwe imadziwikanso kuti polyaluminum chloride yogwira ntchito bwino, PAC yogwira ntchito bwino kapena polyaluminum chloride yowumitsa spray yogwira ntchito bwino. Polyaluminum chloride ndi yoyenera madzi osaphika okhala ndi ma turbidity osiyanasiyana, okhala ndi pH yambiri, koma mphamvu yake ya sedimentation ndi yochepa kwambiri kuposa ya polyacrylamide.
Kufunika kwa polyaluminum chloride ndi chizindikiro chofunikira kwambiri mu polyaluminum, makamaka pazinthu zamadzi akumwa za polyaluminum. Mchere ukakhala wotsika, mtengo wake umakwera, wogula aliyense amatha kugwira ntchito malinga ndi momwe wopanga alili. Kuphatikiza apo, zinthu zosiyanasiyana zopangira, njira zosiyanasiyana zopangira zinthu za polyaluminum chloride zimasiyana mu mchere, zomwe zimafuna kuti wopanga asinthe. Ubwino wazachuma wopanga ndi kugwiritsa ntchito ukhoza kuwonjezeka kwambiri powonjezera kuchuluka kwa mchere wa zinthu za polyaluminum chloride. Kufunika kwa zinthu kumawonjezeka kuchoka pa 65% mpaka 92%, mtengo wa zinthu zopangira ukhoza kuchepetsedwa ndi 20%, ndipo mtengo wogwiritsa ntchito ukhoza kuchepetsedwa ndi 40%.
Mtundu wa polyaluminum chloride nthawi zambiri umakhala woyera, wachikasu, wofiirira, ndipo mitundu yosiyanasiyana ya polyaluminum chloride muukadaulo wogwiritsa ntchito ndi kupanga ndi yosiyana kwambiri. Polyaluminum chloride yokhala ndi trialoxide yomwe ili muyeso wa dziko lonse kuyambira 27% mpaka 30% nthawi zambiri imakhala ufa wolimba wa kha-chikasu mpaka wachikasu ndi wachikasu wopepuka. Mitundu iyi ya polyaluminum chloride imakhala ndi madzi abwino osungunuka. Mu ndondomeko ya kusungunuka, ndi kusintha kwa thupi ndi mankhwala monga electrochemistry, coagulation, adsorption ndi mvula, flocs amapanga mofulumira komanso wandiweyani, amakhala ndi ntchito zambiri, amathamanga mofulumira, ndipo amakhala ndi zotsatira zodziwikiratu zoyeretsa pamadzi ambiri oundana. Polyaluminum chloride yoyera chifukwa imadziwika kuti polyaluminum chloride yoyera yopanda chitsulo, kapena polyaluminum chloride yoyera ya chakudya, poyerekeza ndi polyaluminum chloride yake ndi zinthu zapamwamba kwambiri, zopangira zazikulu ndi ufa wapamwamba wa aluminiyamu hydroxide, hydrochloric acid, njira yopangira ndiyo njira yapamwamba kwambiri yowumitsira utsi wapakhomo. Polyaluminium chloride yoyera imagwiritsidwa ntchito popanga papermaking sizeing agent, shuga decolorizing and clarifying agent, detasting chikopa, mankhwala, zodzoladzola ndi kuponyera molondola komanso mankhwala amadzi.
Zipangizo zopangira za polyaluminium chloride yachikasu ndi calcium aluminate powder, hydrochloric acid, bauxite, zomwe zimagwiritsidwa ntchito kwambiri pochiza zimbudzi ndi madzi akumwa, zinthu zopangira zomwe zimagwiritsidwa ntchito pochiza madzi akumwa ndi aluminiyamu hydroxide powder, hydrochloric acid, pali ufa wochepa wa calcium aluminate, njira yomwe imagwiritsidwa ntchito ndi njira yofayira chimango cha mbale kapena njira yowumitsa. Pochiza madzi akumwa, dzikolo lili ndi zofunikira kwambiri pa zitsulo zolemera, kotero zinthu zopangira ndi njira yopangira ndi zabwino kuposa polyaluminum chloride ya tan. Polyaluminium chloride yachikasu nthawi zambiri imapangidwa ndi kuumitsa ng'oma kapena kuumitsa nsanja yopopera. Zipangizo zopangira za polyaluminum chloride yofiirira ndi calcium aluminate powder, hydrochloric acid, bauxite ndi ufa wachitsulo. Njira yopangira ndikutsatira njira yowumitsa ng'oma, yomwe imagwiritsidwa ntchito makamaka pochiza zimbudzi, chifukwa ufa wachitsulo umawonjezedwa mkati kotero kuti mtundu wake ndi wofiirira, ufa wachitsulo wochulukirapo umawonjezedwa, mtundu wake umakhala wakuda, ufa wachitsulo ngati woposa kuchuluka kwina kwa nthawi inayake umadziwikanso kuti polyaluminum-iron chloride, pochiza zimbudzi umakhala ndi zotsatira zabwino kwambiri.
