I-Polyaluminum Chloride(PAC) iyi-polymer yama-molecule aphezulu enefomula yamakhemikhali ejwayelekile i-Al2(OH)nCl6-nm. Ngenxa yezakhiwo zayo zamakhemikhali ezihlukile, inezinhlobo eziningi zezicelo emikhakheni eyahlukene. Lesi sihloko sikuyisa ngokujulile ensimini ukuze ufunde ukusetshenziswa kwale nhlanganisela.
Okokuqala, i-PAC ihlola kabanzi ukwelashwa kwamanzi. Ingasusa ngempumelelo izinto eziqinile ezilengayo, izinto ze-colloidal, izinto eziphilayo ezinganyibiliki, ngisho nezinhlayiya ezinkulu kakhulu emanzini. Lokhu kufezwa ngenqubo ebizwa ngokuthi i-coagulant, lapho i-PAC isebenza njenge-coagulant. Iqeda amandla imibhoshongo ephezulu, ibangele ukuthi ihlangane ibe yizinhlayiya ezinkulu ezingahlukaniswa kalula emanzini. Umphumela uba amanzi acacile, aphephile ahlangabezana nezindinganiso zekhwalithi zezicelo ezahlukahlukene ezidingekayo, kufaka phakathi amanzi ezimboni. Ama-PAC asetshenziswa nasezinqubweni zokuhlanza amanzi ukuze kuqedwe izinto eziqinile ezilengayo futhi kuthuthukiswe ikhwalithi yamanzi ngokunciphisa ukungcoliswa kwamanzi. Ngokuvamile isetshenziswa kanye namanye amakhemikhali okwelapha amanzi, njenge-PAM, njll., ukuze kufezwe imiphumela emihle kakhulu.
I-Polyaluminum chloride (PAC) ingasetshenziswa njenge-flocculant embonini yokwenza amaphepha ukwelapha indle namanzi ahlanzekile. I-PAC isebenza kahle kakhulu futhi inentengo ephansi, futhi iyathandwa abakhiqizi bephepha. Ngaphezu kwalokho, isebenza futhi njengosizo lokunciphisa, ukugcina kanye nokuhlunga ubukhulu obungathathi hlangothi be-rosin, okungathuthukisa umphumela wobukhulu futhi kuvimbele ukungcoliswa kwezindwangu zomshini wephepha, ama-slurry okwenza amaphepha kanye nezinhlelo zamanzi amhlophe yimikhiqizo ye-hydrolyzate.
Ama-flocculant e-polyaluminum chloride nawo asebenza kahle embonini yezimayini. Asetshenziswa ekuhlanzweni kwezinsimbi futhi adlala indima ebalulekile enqubweni yokuhlukaniswa kwamaminerali. Ngakolunye uhlangothi, ahlukanisa kahle amanzi ne-gangue ukuze kube lula ukusebenzisa amanzi kabusha; ngakolunye uhlangothi, futhi akhipha amanzi odakeni olukhiqiziwe.
Embonini kaphethiloli, i-PAC nayo ithatha indawo ebalulekile. Isetshenziselwa ukususa ukungcola kumafutha ngesikhathi sokukhipha nokucwenga uwoyela. Ayigcini nje ngokukhipha izinto eziphilayo ezinganyibiliki, izinsimbi nezinye izinto eziyingozi emanzini angcolile, kodwa futhi ikhipha futhi isuse amaconsi kawoyela alengayo emanzini. Lapho kubholwa imithombo kawoyela, i-PAC iyasiza futhi ekuqiniseni imbobo yomthombo futhi ivimbele ukulimala kokwakheka. Ngokufaka umjovo embobo yomthombo, ilwa nokucindezela kokwakheka, inciphise umonakalo ongaba khona. Lokhu kungenxa yezakhiwo ze-PAC njenge-ejenti ye-gelling kanye ne-tackifier.
Imboni yokunyathelisa nokufaka udayi yezindwangu nayo iyinkambu ebalulekile yokusetshenziswa kwe-PAC. Njengoba amanzi angcolile akhiqizwa yile mboni enezici zobuningi obukhulu, umbala ojulile, kanye nokuqukethwe okuphezulu kokungcola okungokwemvelo, kuba nzima kakhulu ukuwaphatha. Kodwa-ke, ngesenzo se-PAC, izimbali ze-alum ngesikhathi senqubo yokwelapha amanzi angcolile ziqinile futhi zinkulu, zihlala ngokushesha, futhi umphumela wokwelapha uyamangalisa.
Ngaphezu kwalezi zinsimu ezingenhla, i-PAC idlala indima embonini yamakhemikhali yansuku zonke, kwezolimo, kwezolimo zasemanzini nakweminye imikhakha. Ukusetshenziswa kabanzi kwe-PAC kungabangelwa yizakhiwo zayo zamakhemikhali ezihlukile kanye nokuguquguquka kwazo. Amandla ayo okusebenza njenge-coagulant, stabilizer, kanye ne-tackifier kuyenza ibe ithuluzi eliwusizo ezimbonini ezahlukahlukene. Njengoba ubuchwepheshe nezidingo zemboni ziqhubeka nokukhula, indima ye-PAC ekuhlangabezaneni nalezi zidingo izoqinisa isikhundla sayo njengengxenye ebalulekile ezinqubweni eziningi zezimboni.
