Ungayisebenzisa kanjani i-polyacrylamide ezigayweni zamaphepha futhi iyiphi indima engayidlala?

I-Polyacrylamide iyisengezo sekhwalithi ephezulu esetshenziswa kabanzi embonini yokwenza iphepha.Inezici eziningi eziyingqayizivele nemisebenzi, engathuthukisa kakhulu ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo wezigayo zephepha.

FOkokuqala, i-PAM ingasetshenziselwa ukucubungula i-pulp.Ingasetshenziswa njenge-homogenizer yephepha, isithuthukisi, i-dispersant, usizo lokuhlunga nokunye.Umsebenzi wawo ukuthuthukisa ukufana kwephepha, ukuthuthukisa ngokuphumelelayo ikhwalithi yephepha namandla, ukwandisa izinga lokugcinwa kwama-fillers nemicu emihle, ukunciphisa ukulahlekelwa kwezinto zokusetshenziswa, ukuthuthukisa ukuhlunga nokusebenza kahle kokululama, nokunciphisa ukungcoliswa kwemvelo.Enkambweni yokukhiqizwa kwe-pulp, i-cellulose nokunye ukungcola kuzohlangana ndawonye, ​​​​okuzothinta ikhwalithi yephepha.Ukusebenzisa i-PAM kungahlukanisa lokhu kungcola futhi kuthuthukise ikhwalithi yephepha.Ngaphezu kwalokho, i-PAM ingandisa i-viscosity ye-pulp, okwenza iphepha libe namandla.

Secondly, i-PAM ingasetshenziselwa ukuhlanzwa kwamanzi.Enqubweni yokwenza iphepha, amanzi amaningi asetshenziselwa ukuhlanza nokukhipha iphepha.Lawa manzi angcolile aqukethe inani elikhulu lezinto eziphilayo kanye nokungcola.Uma ikhishelwa ngqo endaweni ngaphandle kokwelashwa, izodala umonakalo omkhulu endaweni ezungezile yemvelo.Ukusetshenziswa kwe-PAM kungahlukanisa lezi zinhlanganisela eziphilayo kanye nokungcola, ngaleyo ndlela kuhlanze ikhwalithi yamanzi.Ngaphezu kwalokho, i-PAM ingasiza futhi ekususeni izinhlayiya ezimisiwe nezinto ze-colloidal emanzini, ikwenze kucace futhi kukhanye kakhudlwana.

In isifinyezo, i-PAM idlala indima ebalulekile ezigayweni zamaphepha.Ngokusebenzisa i-PAM, ikhwalithi yephepha ingathuthukiswa, imfucuza ohlelweni lokukhiqiza ingancishiswa, amanzi angcolile angahlanzwa, futhi indawo ezungezile yemvelo ingavikelwa.Ngakho-ke, ekukhiqizeni iphepha elizayo, i-PAM izoqhubeka nokudlala indima ebalulekile.
