Imikhiqizo eguquliwe ye-polyacrylamide esetshenziswa njengokugcina kanye nezinsiza zokudonsa amanzi ekwenzeni iphepha ngokuvamile iyimikhiqizo eguquliwe ye-polyacrylamide, okuhlanganisa i-anionic polyacrylamide (APAM), i-cationic polyacrylamide (CPAM) kanye ne-amphoteric polyacrylamide (AmPAM), enesisindo samangqamuzana esihlobene nezigidi ezingu-2 ~ 4 million. .
Ngokuvamile, i-APAM yakha isistimu eyinkimbinkimbi nezinye izinhlanganisela ze-cationic ukuze idlale umphumela oqinile wokusiza ukugcina.Isibonelo, ukuhlanganisa ne-aluminium sulfate kungenza i-APAM isondelene kakhulu nemicu, imicu emihle, izigcwalisi, njll., ngaleyo ndlela ithuthukise kakhulu ukugcinwa kwemicu emihle kanye nokugcwalisa.Izinga lokunaka.
I-CPAM ingenye yezinsiza-kugcina ezivame ukusetshenziswa kakhulu ekwenzeni iphepha, futhi imikhiqizo enesisindo samangqamuzana aphezulu kanye ne-low charge density ngokuvamile isetshenziswa.Ukushaja kwayo kuphambene nalokho kwefayibha, futhi ingasetshenziswa iyodwa noma ihlanganiswe ne-bentonite, anion, njll., ukuze kubangele ukugeleza kwephepha ngomshini wokuhlanganisa ibhuloho entweni yephepha, futhi ingakhuphula izinga lokugcinwa kwephepha. iphepha lokugcwalisa nokugqugquzela Ukugxila kwamanzi amhlophe ngaphansi kwenetha kuyancipha.Lapho i-CPAM kanye ne-bentonite ekhokhiswa kabi isetshenziselwa ukwakha uhlelo lokugcinwa kwezinhlayiya kanye ne-drainage aid, usayizi we-flocs wento yephepha eyakhiwe ngokungeza i-CPAM inkulu ngokuqhathaniswa, futhi ngemva kokuba ngaphansi kwamandla aphezulu e-shear ngemva kokudlula iphampu ye-pulp futhi amanye amadivaysi, ama-flocs aphulwa abe yizicucu ezincane, futhi ukwengezwa kwe-bentonite ekhokhiswa kabi ngalesi sikhathi kuzophinde kubhuloho izingcezwana ezincane futhi kwakhiwe ama-flocs amancane kunama-flocs awakhiwe yi-CPAM ekuqaleni.Ngaleyo ndlela, izinga lokugcinwa kwezinto zephepha liyathuthukiswa, futhi ukusebenza kokulingana nokukhipha amanzi kwephepha kuthuthukisiwe.
Uma i-AMPAM isetshenziswa njengendlela yokugcina kanye nosizo lokukhipha amanzi, amaqembu e-anionic axosha udoti we-anionic ku-pulp, futhi amaqembu e-cationic ahlanganisa nemicu kanye nemicu emihle.Ngakho, izinga lokugcinwa kwemicu emihle lithuthukiswa kahle.
