Ingabe i-PolyDADMAC inobuthi: Yembula imfihlakalo yayo?

I-PolyDADMAC, igama lamakhemikhali elibonakala liyinkimbinkimbi futhi liyimfihlakalo, empeleni liyingxenye ebalulekile yokuphila kwethu kwansuku zonke. Njengommeleli wamakhemikhali e-polymer, i-PolyDADMAC isetshenziswa kabanzi emikhakheni eminingi. Kodwa-ke, uyayiqonda ngempela i-chemical properties yayo, uhlobo lomkhiqizo, kanye nobuthi? Okulandelayo, lesi sihloko sizokunikeza ukuqonda okujulile kwe-PolyDADMAC.

Izakhiwo zamakhemikhali ze-PolyDADMAC zinquma izakhiwo zayo ezihlukile. Njenge-polyelectrolyte enamandla ye-cationic, i-PolyDADMAC inikezwa njengoketshezi oluthambile olungenambala noma olukhanyayo oluphuzi, noma ngezinye izikhathi amaparele amhlophe. Izakhiwo zayo eziphephile nezingenabo ubuthi zenza ukuthi isetshenziswe kabanzi emikhakheni efana nokwelashwa kwamanzi, izindwangu, ukwenza amaphepha, kanye namasimu kawoyela. Ngaphezu kwalokho, i-PolyDADMAC incibilika kalula emanzini, ayishisi, inokuhlangana okuqinile, ukuzinza okuhle kwe-hydrolytic, ayizweli ezinguqukweni ze-pH, futhi inezakhiwo ezinhle kakhulu njengokumelana ne-chlorine. Ngokuvamile isetshenziswa njenge-flocculant futhi ngezinye izikhathi ifakwa i-algaecides. Kubikwa ukuthi i-PDMDAAC inomphumela wokubambisana ne-WSCP kanye ne-poly-2-hydroxypropyl dimethylammonium chloride.

I-PolyDADMAC iqala kanjani ukusebenza?

I-PolyDADMAC inamandla futhi idlala indima ehlukene emikhakheni ehlukene. Ngokukhethekile, emkhakheni wokwelashwa kwamanzi, i-PolyDADMAC isetshenziswa njenge-flocculant ye-cationic kanye ne-coagulant. Ngokusebenzisa i-adsorption kanye ne-bridging, ingasusa ngempumelelo izinto eziqinile ezilengisiwe kanye nokungcola emanzini futhi ithuthukise ikhwalithi yamanzi. Embonini yezindwangu, i-PolyDADMAC, njenge-ejenti yokulungisa umbala engena-formaldehyde, ingathuthukisa umphumela wokulungisa umbala wamadayi futhi yenze izindwangu zibe nombala okhanyayo futhi zimelane nokushabalala. Enkambisweni yokwenza iphepha, i-PolyDADMAC isetshenziswa njenge-ejenti yokubamba udoti we-anionic kanye ne-AKD curing accelerator, esiza ekuthuthukiseni ikhwalithi yephepha futhi inciphise izindleko zokukhiqiza. Ngaphezu kwalokho, embonini yensimu kawoyela, i-PolyDADMAC isetshenziswa njengesiqinisi sobumba sokubhoboza kanye ne-acid fracturing cationic modifier ekufakweni kwamanzi ukuze kuthuthukiswe ukubuyiswa kwensimu kawoyela.

Kodwa-ke, i-PolyDADMAC akuyona into eyigugu. Nakuba inezakhiwo eziningi ezinhle kakhulu kanye nezindawo zokusetshenziswa, kusadingeka uqaphele izinkinga zokuphepha uma uyisebenzisa. Isibonelo, ukuxhumana ngqo nesikhumba namehlo kufanele kugwenywe ngesikhathi sokusetshenziswa ukuze kuvinjelwe ukucasuka. Ngaphezu kwalokho, kufanele ivalwe futhi igcinwe ngemva kokusetshenziswa ukuze kugwenywe ukuthintana nama-oxidant anamandla futhi igcinwe endaweni epholile neyomile. Nakuba i-PolyDADMAC ingenabo ubuthi, kusadingeka ukuthi uyisebenzise ngokucophelela futhi ulandele imithetho yokuphepha kanye nezinqubo zokusebenza.

Ngamafuphi, i-PolyDADMAC, njengekhemikhali ye-polymer, isetshenziswa kabanzi emikhakheni eminingi. Izakhiwo zayo zamakhemikhali ezihlukile kanye nokusebenza kwayo okuhle kakhulu kwenza kube ukukhetha okuhle kakhulu kokwelashwa kwamanzi, izindwangu, iphepha, kanye nezinsimu zikawoyela. Kodwa-ke, kusadingeka unake izinkinga zokuphepha ngesikhathi sokusetshenziswa futhi ulandele imithethonqubo efanele kanye nezinqubo zokusebenza. Kuphela ngokuqinisekisa ukusetshenziswa okuphephile nokunengqondo kwe-PolyDADMAC lapho singabona khona ngokugcwele amandla ayo futhi silethe ukulula kanye nezinzuzo ezengeziwe empilweni yethu nasemsebenzini.
