I-PolyDADMAC, igama lekhemikhali elibonakala liyinkimbinkimbi futhi liyimfihlakalo, empeleni liyingxenye ebalulekile yokuphila kwethu kwansuku zonke. Njengommeleli wamakhemikhali e-polymer, i-PolyDADMAC isetshenziswa kabanzi emikhakheni eminingi. Nokho, ingabe uyaziqonda ngempela izakhiwo zayo zamakhemikhali, uhlobo lomkhiqizo, kanye nobuthi? Okulandelayo, lesi sihloko sizokunikeza ukuqonda okujulile kwe-PolyDADMAC.
Amakhemikhali e-PolyDADMAC anquma izici zayo eziyingqayizivele. Njenge-cationic polyelectrolyte eqinile, i-PolyDADMAC inikezwa njengoketshezi lwe-viscous olukhanyayo olungenambala ukuya kokuphuzi okukhanyayo, noma kwesinye isikhathi amaparele amhlophe. Izici zayo eziphephile nezingenabo ubuthi ziyenza isetshenziswe kabanzi emikhakheni efana nokwelashwa kwamanzi, izindwangu, ukwenza amaphepha, nezinkundla zikawoyela. Ukwengeza, i-PolyDADMAC incibilika kalula emanzini, ingashi, inokuhlangana okuqinile, ukuzinza okuhle kwe-hydrolytic, ayizwani nezinguquko ze-pH, futhi inezici ezinhle kakhulu ezifana nokumelana ne-chlorine. Ngokuvamile isetshenziswa njenge-flocculant futhi ngezinye izikhathi ifakwe nge-algaecides. Kubikwa ukuthi i-PDMDAAC inomphumela we-synergistic nge-WSCP kanye ne-poly-2-hydroxypropyl dimethylammonium chloride.
Ngabe iPolyDADMAC ingena kanjani? I-PolyDADMAC inamandla futhi idlala izindima ezihlukene emikhakheni ehlukene. Ngokuqondile, emkhakheni wokwelashwa kwamanzi, i-PolyDADMAC isetshenziswa njenge-cationic flocculant kanye ne-coagulant. Ngokusebenzisa i-adsorption kanye nokuhlanganisa ibhuloho, ingasusa ngempumelelo izinto eziqinile ezimisiwe nokungcola emanzini futhi ithuthukise ikhwalithi yamanzi. Embonini yezindwangu, i-PolyDADMAC, njenge-ejenti yokulungisa imibala engena-formaldehyde, ingathuthukisa umphumela wokulungisa imibala futhi yenze izindwangu zibe nombala ogqamile futhi zimelane nokufiphala. Enqubweni yokwenza amaphepha, i-PolyDADMAC isetshenziswa njenge-ejenti yokubamba udoti we-anionic kanye ne-AKD yokwelapha i-accelerator, esiza ukuthuthukisa ikhwalithi yephepha nokunciphisa izindleko zokukhiqiza. Ngaphezu kwalokho, embonini yensimu kawoyela, i-PolyDADMAC isetshenziswa njenge-stabilizer yobumba yokumba kanye ne-acid fracturing cationic modifier emjovweni wamanzi ukuze kuthuthukiswe ukubuyiswa kwensimu kawoyela.
Kodwa-ke, i-PolyDADMAC ayiyona inhlamvu yesiliva. Nakuba inezindawo eziningi ezinhle kakhulu nezindawo ezisetshenziswayo, kusadingeka ukuthi unake izindaba zokuphepha lapho uyisebenzisa. Isibonelo, ukuthintana ngqo nesikhumba namehlo kufanele kugwenywe ngesikhathi sokusetshenziswa ukuvimbela ukucasuka. Ngaphezu kwalokho, kufanele ivalwe futhi igcinwe ngemva kokusetshenziswa ukugwema ukuthintana nama-oxidants aqinile futhi igcinwe endaweni epholile neyomile. Nakuba i-PolyDADMAC ingenabo ubuthi, usadinga ukuyisebenzisa ngokuqapha futhi ulandele imithetho yokuphepha nezinqubo zokusebenza.
Ukufingqa, i-PolyDADMAC, njengekhemikhali ye-polymer, isetshenziswa kabanzi emikhakheni eminingi. Izakhiwo zayo zamakhemikhali eziyingqayizivele nokusebenza okuhle kakhulu kuyenza ibe inketho efanelekile yokwelashwa kwamanzi, izindwangu, amaphepha, nezinkundla zikawoyela. Kodwa-ke, kusadingeka ukuthi unake izindaba zokuphepha ngesikhathi sokusetshenziswa futhi ulandele imithethonqubo efanele nezinqubo zokusebenza. Kuphela ngokuqinisekisa ukusetshenziswa okuphephile nokunengqondo kwe-PolyDADMAC singakwazi ukubona ngokugcwele amandla ayo futhi ilethe ukunethezeka nezinzuzo ezengeziwe empilweni yethu nasemsebenzini.
