I-Polyaluminum chloride iyisihlanzi samanzi esisebenza kahle kakhulu, esingahlanza, sisuse iphunga, sisuse umbala, njll. Ngenxa yezici zaso ezinhle kakhulu kanye nezinzuzo kanye nobubanzi bokusetshenziswa, umthamo ungancishiswa ngaphezu kuka-30% uma kuqhathaniswa nezihlanzi zamanzi zendabuko, futhi izindleko zingongiwa ngaphezu kuka-40%. Isibe isihlanzi samanzi esihle kakhulu esiqashelwa ekhaya nakwamanye amazwe. Ngaphezu kwalokho, i-polyaluminum chloride ingasetshenziswa futhi ukuhlanza ikhwalithi yamanzi ekhethekile njengamanzi okuphuza kanye nokuhlinzekwa kwamanzi ompompi, njengokususwa kwensimbi, ukususwa kwe-cadmium, ukususwa kwe-fluorine, ukususwa kokungcola okunemisebe, kanye nokususwa kwe-oyela.
Izici ze-PAC (i-Poly Aluminium Chloride):
I-Polyaluminum chloride iphakathi kwe-ALCL3 ne-ALNCL6-NLm] lapho u-m emele izinga le-polymerization kanti u-n umele izinga lokungathathi hlangothi komkhiqizo we-PAC. I-Polyaluminum chloride efingqiwe njenge-PAC ivame ukubizwa nangokuthi i-polyaluminum chloride noma i-coagulant, njll. Umbala uphuzi noma uphuzi okhanyayo, onsundu omnyama, i-resinous solid emnyama. Umkhiqizo unezakhiwo eziqinile zokuhlanganisa i-adsorption, futhi ngesikhathi senqubo ye-hydrolysis, kwenzeka izinqubo zomzimba nezamakhemikhali ezifana nokujiya, ukujiya kanye nemvula.
Isicelo se-PAC (i-Poly Aluminium Chloride):
I-Polyaluminum chloride isetshenziswa kakhulu ekuhlinzekweni kwamanzi emadolobheni nasekuhlanzweni kwamanzi: amanzi omfula, amanzi okugcina amanzi, amanzi angaphansi komhlaba; ukuhlanzwa kwamanzi ezimboni, ukwelashwa kwendle yasemadolobheni, ukubuyiswa kwezinto eziwusizo emanzini angcolile ezimbonini kanye nezinsalela zendle, ukukhuthaza ukuthuthwa kwamalahle acoliwe emanzini angcolile okugeza amalahle, ukukhiqizwa kwesitashi Ukuphinda kusetshenziswe isitashi; i-polyaluminium chloride ingahlanza amanzi angcolile ahlukahlukene ezimbonini, njengokuthi: ukuphrinta nokudaya amanzi angcolile, amanzi angcolile esikhumba, amanzi angcolile aqukethe i-fluorine, amanzi angcolile ensimbi esindayo, amanzi angcolile aqukethe uwoyela, amanzi angcolile okwenza iphepha, amanzi angcolile okugeza amalahle, ukumba amanzi angcolile, ukukhiqiza amanzi angcolile, amanzi angcolile ensimbi, ukucubungula inyama, njll.; I-Polyaluminum chloride yokwelapha indle: usayizi wokwenza iphepha, ukuhluza ushukela, ukubumba, ukuvimbela imibimbi, isithwali se-catalyst, ukulungiswa kwe-cement ngokushesha, izinto zokusetshenziswa zokuhlobisa.
Inkomba yekhwalithi ye-PAC (i-polyaluminum chloride)
Yiziphi izinkomba ezintathu ezibaluleke kakhulu zekhwalithi ze-PAC (i-polyaluminum chloride)? Usawoti, inani le-PH, kanye nokuqukethwe kwe-alumina okunquma ikhwalithi ye-polyaluminum chloride yizinkomba ezintathu ezibaluleke kakhulu zekhwalithi ye-polyaluminum chloride.
1. Usawoti.
Izinga le-hydroxylation noma i-alkaliization yefomu elithile ku-PAC (i-polyaluminum chloride) libizwa ngokuthi izinga le-basicity noma i-alkalinity. Ngokuvamile livezwa yi-molar ratio ye-aluminium hydroxide B=[OH]/[Al] percentage. Usawoti ungenye yezinkomba ezibaluleke kakhulu ze-polyaluminum chloride, ehlobene eduze nomphumela we-flocculation. Uma ukuhlushwa kwamanzi aluhlaza kuphakeme futhi usawoti uphakeme, kulapho umphumela we-flocculation uba ngcono khona. Ngamafuphi, ebangeni le-turbidity yamanzi aluhlaza angu-86~10000mg/L, usawoti omuhle kakhulu we-polyaluminum chloride ungu-409~853, kanti ezinye izici eziningi ze-polyaluminum chloride zihlobene nosawoti.
2. Inani le-pH.
I-pH yesisombululo se-PAC (polyaluminum chloride) nayo iyinkomba ebalulekile. Imelela inani le-OH- esimweni samahhala esixazululweni. Inani le-pH le-polyaluminum chloride ngokuvamile liyanda ngokwanda kwesisekelo, kodwa koketshezi olunezinhlanganisela ezahlukene, akukho buhlobo obuhambisanayo phakathi kwenani le-pH kanye nesisekelo. Uketshezi olunesilinganiso esifanayo sosawoti lunesilinganiso se-pH esihlukile lapho isilinganiso sihlukile.
3. Okuqukethwe kwe-alumina.
Okuqukethwe kwe-alumina ku-PAC (i-polyaluminum chloride) kuyisilinganiso sezingxenye ezisebenzayo zomkhiqizo, ezinobuhlobo obuthile nobuningi besisombululo. Ngokuvamile, lapho ubukhulu besisombululo bukhula, okuqukethwe kwe-alumina kuyanda. I-viscosity ye-polyalumina chloride ihlobene nokuqukethwe kwe-alumina, futhi i-viscosity iyanda ngokwanda kokuqukethwe kwe-alumina. Ngaphansi kwezimo ezifanayo kanye nokuhlushwa okufanayo kwe-alumina, i-viscosity ye-polyalumina chloride iphansi kuneye-aluminium sulfate, evumela kakhulu ukuthuthwa nokusetshenziswa.
