Kuyini i-Polyaluminium Chloride?
I-Polyaaluminium chloride, efushaniswe ngokuthi i-PAC, iyi-ejenti yokwelapha amanzi e-polymer engakhiqizi izinto eziphilayo. Lezi zinhlobo zihlukaniswe ngezigaba ezimbili: ukusetshenziswa kwamanzi okuphuza ekhaya kanye nokusetshenziswa kwamanzi okuphuza okungewona awasekhaya, ngalinye lingaphansi kwezindinganiso ezahlukene ezifanele. Ukubukeka kuhlukaniswe ngezinhlobo ezimbili: uketshezi kanye nokuqinile. Ngenxa yezingxenye ezahlukene eziqukethwe ezintweni zokusetshenziswa, kunomehluko ekubukekeni kombala kanye nemiphumela yokusetshenziswa.
I-Polyaaluminium chloride iyisithako esiqinile esingenambala noma esiphuzi. Isixazululo sayo siwuketshezi olukhanyayo olungenambala noma oluphuzi, oluncibilika kalula emanzini futhi oluncibilikisa utshwala, olungancibiliki ku-anhydrous alcohol kanye ne-glycerol. Kufanele igcinwe endaweni yokugcina izinto epholile, enomoya, eyomile, nehlanzekile. Ngesikhathi sokuthuthwa, kuyadingeka ukuvikela emvuleni naselangeni eliqondile, ukuvimbela ukubola, kanye nokuphatha ngokucophelela ngesikhathi sokulayisha nokukhulula impahla ukuze kuvinjelwe umonakalo wokupakisha. Isikhathi sokugcina imikhiqizo ewuketshezi siyizinyanga eziyisithupha, kanti imikhiqizo eqinile ingunyaka owodwa.
Izinto zokwelapha amanzi zisetshenziswa kakhulu ekuhlanzeni amanzi okuphuza, amanzi angcolile asezimbonini, kanye nendle yasemadolobheni, njengokususa insimbi, i-fluorine, i-cadmium, ukungcola okunemisebe, kanye namafutha antantayo. Iphinde isetshenziselwe ukwelapha amanzi angcolile asezimbonini, njengokunyathelisa nokudaya amanzi angcolile. Iphinde isetshenziswe ekubunjweni okunembile, kwezokwelapha, ekwenzeni iphepha, enjoloba, ekwenzeni isikhumba, kuphethiloli, embonini yamakhemikhali, kanye nakumadayi. I-Polyaluminium chloride isetshenziswa njenge-ejenti yokwelapha amanzi kanye nezinto zokuhlobisa ekuphathweni kobuso.
I-Polyaaluminium chloride ine-adsorption, coagulation, imvula kanye nezinye izakhiwo. Iphinde ibe nokuqina okubi, ubuthi, kanye nokugqwala. Uma ifafazwe ngephutha esikhumbeni, hlanza ngokushesha ngamanzi. Abasebenzi bokukhiqiza kufanele bagqoke izingubo zomsebenzi, imaski, amagilavu, namabhuzu enjoloba amade. Imishini yokukhiqiza kufanele ivalwe, futhi umoya wokusebenza kufanele ube muhle. I-Polyaaluminium chloride iyabola uma ishiswa ngaphezu kuka-110 ℃, ikhiphe igesi ye-hydrogen chloride, bese ekugcineni ibola ibe yi-aluminium oxide; Isabela ne-asidi ukuze idlule ekuncipheni kwe-polymerization, okuholela ekunciphiseni kwezinga le-polymerization kanye ne-alkalinity, ekugcineni iguquke ibe usawoti we-aluminium. Ukusebenzisana ne-alkali kungandisa izinga le-polymerization kanye ne-alkalinity, ekugcineni kuholele ekwakhekeni kwe-aluminium hydroxide precipitate noma usawoti we-aluminate; Uma ixutshwe ne-aluminium sulfate noma amanye usawoti we-acid amaningi, imvula ikhiqizwa kalula, okunganciphisa noma kulahlekelwe ngokuphelele ukusebenza kwe-coagulation.
