Kodi Polyaluminium Chloride ndi chiyani?
Polyaluminium chloride, yofupikitsidwa ngati PAC, ndi inorganic polima poyeretsa madzi. Mitunduyi imagawidwa m'magulu awiri: kugwiritsa ntchito madzi akumwa m'nyumba komanso kugwiritsa ntchito madzi akumwa omwe si apakhomo, iliyonse ili ndi miyezo yosiyana. Maonekedwe agawidwa m'mitundu iwiri: madzi ndi olimba. Chifukwa cha zigawo zosiyanasiyana zomwe zili muzopangira, pali kusiyana kwa maonekedwe a maonekedwe ndi zotsatira za ntchito.
Polyaluminium chloride ndi yopanda mtundu kapena yolimba yachikasu. Yankho lake ndi madzi opanda mtundu kapena achikasu bulauni owonekera, osungunuka mosavuta m'madzi ndikusungunula mowa, osasungunuka mu mowa wa anhydrous ndi glycerol. Iyenera kusungidwa m'malo ozizira, mpweya wabwino, wouma, ndi waukhondo. Panthawi yoyendetsa, ndikofunikira kuteteza mvula ndi kuwala kwa dzuwa, kuteteza kufooka, ndikugwirira ntchito mosamala pakukweza ndi kutsitsa kuti zisawonongeke. Nthawi yosungiramo zinthu zamadzimadzi ndi miyezi isanu ndi umodzi, ndipo pazinthu zolimba ndi chaka chimodzi.
Zopangira madzi zimagwiritsidwa ntchito makamaka kuyeretsa madzi akumwa, madzi otayira m'mafakitale, ndi zimbudzi zapakhomo, monga kuchotsa chitsulo, fluorine, cadmium, kuipitsidwa ndi radioactive, ndi mafuta oyandama. Amagwiritsidwanso ntchito popangira madzi otayira m'mafakitale, monga kusindikiza ndi kudaya madzi oipa. Amagwiritsidwanso ntchito popanga mwaluso, mankhwala, kupanga mapepala, labala, kupanga zikopa, mafuta, makampani opanga mankhwala, ndi utoto. Polyaluminium chloride imagwiritsidwa ntchito ngati mankhwala ochizira madzi komanso zopangira zodzikongoletsera pochiritsa pamwamba.
Polyaluminium chloridehas adsorption, coagulation, mpweya ndi zina. Ilinso ndi kusakhazikika bwino, kawopsedwe, komanso kuwononga. Ngati mwangozi wawaza pakhungu, muzimutsuka nthawi yomweyo ndi madzi. Ogwira ntchito yopangira zinthu ayenera kuvala zovala zantchito, masks, magolovesi, ndi nsapato zazitali za labala. Zida zopangira ziyenera kusindikizidwa, ndipo mpweya wabwino wa malo ochitirako msonkhano ukhale wabwino. Polyaluminium chloride imawola ikatenthedwa pamwamba pa 110 ℃, kutulutsa mpweya wa hydrogen chloride, ndipo pamapeto pake imawola kukhala aluminium oxide; Imakhudzidwa ndi asidi kuti iwonongeke, zomwe zimapangitsa kuchepa kwa dipuloma ya polymerization ndi alkalinity, kenako kusandulika mchere wa aluminiyamu. Kuyanjana ndi zamchere kungapangitse kuchuluka kwa polymerization ndi alkalinity, komwe kumatsogolera ku mapangidwe a aluminiyamu hydroxide precipitate kapena aluminate mchere; Mukasakaniza ndi aluminiyamu sulphate kapena mchere wina wa multivalent acid, mvula imapangidwa mosavuta, yomwe imatha kuchepetsa kapena kutayika kwathunthu kugwira ntchito kwa coagulation.
