Polyacrylamideligama eliqhelekileyo le-homopolymers ye-acrylamide okanye i-copolymers kunye nezinye ii-monomers. Yenye yezona zinto zisetyenziswa kakhulu iipolima ezinyibilikayo emanzini. I-Polyacrylamide ikhona ngendlela yeegranule ezimhlophe kwaye ingahlelwa kwiindidi ezine: i-non-ionic, i-anionic, i-cationic, kunye ne-amphoteric ionic.
Ukusetyenziswa kwePolyacrylamide kwiNdawo yokuPapermaking
Inkqubo yokwenza iphepha iquka amanqanaba amaninzi, kuquka ukucofa, ukucocwa, ukucocwa, ukucocwa, kunye nokwenza. Ngexesha lezi nkqubo, ukungcola okuhlukahlukeneyo okunje ngeefayibha, iifayili, kunye nezohlwayo ziyenziwa. Ukuba ezi zinto zingcolileyo azisuswanga ngokufanelekileyo kwi-pulp, zingakhokelela kwiingxaki ezifana nokukhupha amanzi kunye namandla aphantsi ephepha. I-Polyacrylamide isetyenziswa ikakhulu njenge-dispersant, i-retention aid, i-drainage aid, i-flocculant, kunye ne-agent yokulinganisa kwinkqubo yokwenza iphepha.
Ⅰ. Ukuchithachitha
Ukongeza i-polyacrylamide dispersant ngexesha lenkqubo yokwenza iphepha kunokuthintela ngokufanelekileyo i-agglomeration ye-fibers kunye nokuphucula ukufana kwephepha. Imali eyongezelelweyo ephantsi inokukhuthaza ukusasazwa kakuhle kweefayili zephepha kunye nokufezekisa umphumo obalaseleyo wokwenza iphepha. Kwakhona kunokuphucula ukufana kwe-pulp kunye nokuthamba kwephepha, kunye nokuphucula iimpawu zamandla zephepha. Ifanelekile kwiimveliso zamaphepha asekhaya ahlukeneyo njengephepha langasese, i-napkins, izicubu zobuso, kunye namanye amaphepha amancinci. Kwezinye ii-mills zephepha, ziyakwazi ukuthatha indawo ngokupheleleyo i-Polyethylene Oxide (PEO).
Ⅱ. Ugcino loNcedo
I-PAM isetyenziswa ngokuqhelekileyo njengoncedo lokugcina kwishishini lephepha lokunyusa izinga lokugcinwa kwefiber kunye nokunciphisa ukukhutshwa kwamanzi amdaka. Umgaqo wayo wokusebenza kukwenza iiflocs ezinkulu ezinamaqhekeza amancinci, anokususwa ngokulula kwi-pulp ngokusebenzisa i-filtration okanye i-sedimentation.
Ⅲ. Uncedo lwamanzi amdaka
I-PAM inokuphinda isebenze njengoncedo lwamanzi kwinkqubo yokwenza iphepha. Yandisa izinga lokukhupha amanzi, ivumela ukukhupha amanzi ngokukhawuleza nangokufanelekileyo kwephepha kumatshini wephepha. Oku kunceda ukwandisa isantya sokuvelisa kunye nokunciphisa ukusetyenziswa kwamandla ngokunciphisa ixesha lokumisa elifunekayo kwiphepha.
Ⅳ. Iarhente yokulinganisa
Kwezinye iimeko, i-polyacrylamide isetyenziswa njenge-arhente yokulinganisa ekwenzeni iphepha ukulawula ukungena kwamanzi kunye nolunye ulwelo kwiphepha lephepha. Oku kunceda ekufezekiseni iipropati ezinqwenelekayo ezifana nokuxhathisa kwamanzi kunye ne-inki yokubamba, ngokukodwa kwizicelo apho iphepha lifuna ukumelana nokufuma okanye iinkqubo zokushicilela.
Ⅴ. I-Flocculant
Ngexesha lenkqubo yokucocwa kwamanzi amdaka kwiindawo zokusila zephepha, i-polyacrylamide ingasetyenziswa njenge-flocculant yokususa izinto eziqinileyo ezimisiweyo kunye nezingcolisi kumanzi amdaka. Inceda ukwenza amasuntswana amakhulu abizwa ngokuba ziiflocs, anokususwa ngokulula ngentlenga okanye inkqubo yokuhluza. Oku kunegalelo ekunciphiseni ukungcoliseka kwamanzi nokuphucula ukuzinza kokusingqongileyo kwishishini lokwenza amaphepha.
Ngokubanzi, iipropathi eziguquguqukayo ze-polyacrylamide zenza ukuba ibe sisongezo esiyimfuneko kwishishini lokwenza iphepha, igalelo kuphuculo lobuchule, umgangatho wemveliso, kunye nokusebenza kweemveliso zephepha. Ukusetyenziswa kwe-polyacrylamide kwintsimi ye-papermaking igubungela lonke ikhonkco loshishino lwe-papermaking, ukusuka kwimveliso yephepha ukuya kunyango lwamanzi amdaka. Akukona nje ukuphucula umgangatho kunye nokusebenza kakuhle kwephepha, ukunciphisa iindleko zokuvelisa, kodwa kwenza igalelo elihle ekukhuselweni kwendalo.
