Ingabe i-polydadmac inobuthi: yembula imfihlakalo yayo?

I-PolydadMac, igama elibonakala lilinkimbinkimbi futhi eliyinqaba lamakhemikhali, empeleni liyingxenye ebalulekile yezimpilo zethu zansuku zonke. Njengommeleli wamakhemikhali we-polymer, i-polydadmac isetshenziswa kabanzi emikhakheni eminingi. Kodwa-ke, ingabe uyayiqonda ngempela izakhiwo zamakhemikhali, ifomu lomkhiqizo, nobuthi? Okulandelayo, le ndatshana izokunikeza ukuqonda okujulile kwePolydadMac.

Izakhiwo zamakhemikhali zePolydadmac zithola izakhiwo zayo ezihlukile. Njenge-polyelectsyte eqinile ye-cationic, i-polydadmac ihlinzekwa njenge-colorless ukukala okubukeka okuphuzi okuphuzi, noma kwesinye isikhathi amaparele amhlophe. Izakhiwo zayo eziphephile nezingezinyo ezinobuthi zikwenza kusetshenziswe kabanzi emasimini anjengokwelashwa kwamanzi, izindwangu, ukupaka amapakethe kanye namasimu e-oyela. Ngokwengeziwe, i-polydadmac ithambekele kalula emanzini, ingenakuvutha, inokubumbana okuqinile, ukuqina okuhle kwe-hydrolytic, akunangqondo ezinguquko e-PH, futhi kunezinguquko ezinhle kakhulu njengokumelana ne-chlorine. Imvamisa isetshenziswa njenge-flocculant futhi kwesinye isikhathi idonswa ngama-algaecides. Kubikwa ukuthi i-PDMDAAC inomphumela we-synergistic nge-WSCP ne-Poly-2-Hydroxypropyly dimethylayinium chloride.

Ngabe uPolydadMac uqala kanjani ukudlala?

I-PolydadMac inamandla futhi idlala izindima ezahlukahlukene emikhakheni ehlukene. Ngokukhethekile, emkhakheni wokwelashwa kwamanzi, i-polydadmac isetshenziswa njenge-catioc flocculant kanye ne-coabulayo. Ngokusebenzisa ama-adsorption kanye ne-bridging, ingasusa ngempumelelo ama-solids amisiwe nokungcola emanzini bese uthuthukisa ikhwalithi yamanzi. Embonini yezindwangu, i-polydadmac, njengomenzeli we-ejenti olungiselelwe umbala we-formaldehyde, angathuthukisa umphumela wokulungiswa kombala wedayi futhi enze izindwangu zinemibala egqamile futhi zimelana nokuphela. Enqubweni yokuphamba, i-polydadmac isetshenziswa njenge-agent ye-anionic kati udoti kanye ne-accelerator ye-akd yelapha, isiza ukuthuthukisa ikhwalithi yephepha futhi inciphise izindleko zokukhiqiza. Ngaphezu kwalokho, embonini yensimu yamafutha, i-polydadmac isetshenziswa njenge-stabilizer Clast yokushayela kanye ne-acid fiacting cutioc modicier emjovo wamanzi ukuthuthukisa ukululama kwensimu yamafutha.

Kodwa-ke, i-polydadmac akuyona inhlamvu yesiliva. Yize inezindawo eziningi ezinhle kakhulu nezindawo zohlelo lokusebenza, usadinga ukunaka izindaba zokuphepha lapho uzisebenzisa. Isibonelo, ukuxhumana ngqo nesikhumba namehlo kufanele kugwenywe ngesikhathi sokusebenzisa ukuvikela ukucasuka. Phezu kwalokho, kufanele kubekwe uphawu futhi kugcinwe ngemuva kokusebenzisa ukugwema ukuxhumana nabantu abanamandla ooxidants futhi kugcinwe endaweni epholile neyomile. Yize i-polydadmac ayinobuthi, usadinga ukuyisebenzisa ngokuqapha futhi ulandele imithetho yezokuphepha nezinqubo ezisebenzayo.

Ukufingqa, i-polydadmac, njengekhemikhali le-polymer, isetshenziswa kabanzi emikhakheni eminingi. Izakhiwo zayo ezihlukile zamakhemikhali nokusebenza okuhle kwenza kube yisinqumo esihle sokwelashwa kwamanzi, izindwangu, ephepheni kanye namasimu kawoyela. Kodwa-ke, usadinga ukunaka izindaba zokuphepha ngesikhathi sokusebenzisa bese ulandela imithetho efanele nezinqubo zokusebenza. Kuphela ngokuqinisekisa ukusetshenziswa okuphephile nokunengqondo kwePolydadMac singabona ngokuphelele amandla aso futhi silethe lula kakhulu nezinzuzo empilweni yethu nomsebenzi.
