Iimveliso ezilungisiweyo ze-polyacrylamide ezisetyenziswa njengogcino kunye nezixhobo zokuhambisa amanzi kwi-papermaking zidla ngokulungiswa imveliso ye-polyacrylamide, kuquka i-anionic polyacrylamide (APAM), i-cationic polyacrylamide (CPAM) kunye ne-amphoteric polyacrylamide (AmPAM), kunye nobunzima be-molecular yezigidi ezi-2 ~ 4 million. .
Ngokuqhelekileyo, i-APAM yenza inkqubo enzima kunye nezinye iikhompawundi ze-cationic ukuze zidlale umphumo onamandla wokugcina.Ngokomzekelo, ukudibanisa ne-aluminium sulfate kunokwenza i-APAM idibanise ngokusondeleyo kunye neefayili, iifayili ezintle, iifayili, njl.Izinga lokuqwalaselwa.
I-CPAM yenye yezona zinto zisetyenziswa ngokuqhelekileyo ukugcinwa kwezinto ezisetyenziswa ngokuqhelekileyo ekwenzeni iphepha, kwaye iimveliso ezinobunzima be-molecular kunye ne-low charge density zisetyenziswa ngokubanzi.Intlawulo yayo ichasene nefiber, kwaye ingasetyenziselwa yodwa okanye idityaniswe ne-bentonite, i-anion, njl., ukubangela ukujikeleza kwephepha ngomatshini wokuqhawula kwimpahla yephepha, kwaye inokunyusa izinga lokugcinwa kwephepha. iphepha lokuzalisa iphepha kunye nokukhuthaza Ukugxininiswa kwamanzi amhlophe phantsi komnatha kuyancipha.Xa i-CPAM kunye ne-bentonite ehlawuliswa kakubi isetyenziselwa ukwenza inkqubo yokuncedisa ukugcinwa kwe-particulate kunye ne-drainage, ubungakanani beeflocs zezinto zephepha ezenziwe ngokudibanisa i-CPAM zikhulu kakhulu, kwaye emva kokuba ziphantsi kwegunya eliphezulu lokucheba emva kokudlula kwipompo yepompo kwaye ezinye izixhobo, ii-flocs ziqhekezwe zibe ngamaqhekeza amancinci, kwaye ukongezwa kwe-bentonite ehlawuliswa kakubi ngeli xesha kuya kuphinda kubhubhise amaqhekeza amancinci kwaye zenze iimbumba ezincinci kuneengqungquthela ezenziwe yi-CPAM.Ngaloo ndlela, izinga lokugcinwa kwezinto zephepha liphuculwe, kwaye ukulingana kunye nokusebenza kwe-drainage yephepha kuphuculwe.
Xa i-AMPAM isetyenziselwa ukugcinwa kunye noncedo lokukhupha amanzi, amaqela e-anionic agxotha udoti we-anionic kwi-pulp, kwaye amaqela e-cationic adibanisa kunye nemicu kunye nemicu emihle.Ngaloo ndlela, izinga lokugcinwa kweefibers ezintle liphuculwe kakuhle.
