Polyacrylamide(PAM) i-polymer ye-molecular weight high esetyenziswa ngokubanzi kwiinkqubo zokunyanga kwamanzi kwiinkalo ezahlukeneyo. Inobunzima beemolekyuli ezahlukeneyo, i-ionicities, kunye nezakhiwo ukuze zilungele iimeko ezahlukeneyo zokusetyenziswa kwaye zinokuthi zenziwe ngokwezifiso kwiimeko ezizodwa. Ngokusebenzisa i-neutralization yombane kunye ne-polymer adsorption kunye ne-bridging, i-PAM inokukhuthaza i-agglomeration esheshayo kunye ne-sedimentation yamasuntswana amisiweyo, ukuphucula umgangatho wamanzi. Eli nqaku liza kukhangela kwizicelo ezithile kunye neempembelelo ze-PAM kunyango lwamanzi kwiinkalo ezahlukeneyo.
Kunyango lwamanzi amdaka asekhaya, iPAM isetyenziswa ikakhulu kwi-flocculation sedimentation kunye ne-sludge dewatering. Ngokunciphisa iipropathi zombane kunye nokusebenzisa i-adsorbing bridging effects, i-PAM inokukhawulezisa i-agglomeration yezinto eziqinileyo ezimisiweyo emanzini ukuze zenze iiflocs zamasuntswana amakhulu. Ezi flocs kulula ukuzinza kunye nokucoca, ngaloo ndlela zisusa ngokufanelekileyo ukungcola emanzini kunye nokufezekisa injongo yokucoca umgangatho wamanzi. Ukusetyenziswa kwe-PAM kunokuphucula ukusebenza kakuhle kokunyanga kwamanzi amdaka kunye nokunciphisa iindleko zonyango.
Kwintsimi ye-papermaking, i-PAM isetyenziswa kakhulu njengenkxaso yokugcina, i-filter aid, i-dispersant, njl. Ngokongeza i-PAM, izinga lokugcinwa kweefayili kunye nemicu emihle kwiphepha linokuphuculwa, ukunciphisa ukusetyenziswa kwezinto eziluhlaza, kunye nokuphucula. ukuhluzwa kunye nokusebenza kokuphelelwa ngamanzi emzimbeni kwi-pulp. Ukongezelela, i-PAM inokusebenza njenge-non-silicon polymer stabilizer kwinkqubo yokucoca, ukuphucula ubumhlophe kunye nokukhanya kwephepha.
Kwisityalo sotywala ukucocwa kwamanzi amdaka,PAMisetyenziswa ngokuyintloko kwinkqubo yokuchithwa kwe-sludge. Kwiinkqubo zokuvelisa utywala kunye nezixhobo ezahlukeneyo kunye neenkqubo zokucocwa kwamanzi amdaka, kubalulekile ukukhetha i-cationic polyacrylamide ene-ioncity efanelekileyo kunye nobunzima bemolekyuli. Uvavanyo lokukhetha ngokusebenzisa imifuniselo yebheaker yovavanyo yenye yeendlela ezisetyenziswa ngokuqhelekileyo.
Amanzi amdaka okutya, kunye nezinto eziphezulu zezinto eziphilayo kunye nomxholo oqinileyo omisiweyo, afuna iindlela ezifanelekileyo zonyango. Indlela yemveli ibandakanya ukubola komzimba kunye nokuvutshelwa kwe-biochemical. Nangona kunjalo, kwizicelo ezisebenzayo, ii-polymer flocculants zihlala ziyimfuneko kwi-sludge dehydration kunye neminye imisebenzi yonyango. Uninzi flocculants ezisetyenziswa kule nkqubo cationic Polyacrylamide iimveliso series. Ukukhetha imveliso efanelekileyo Polyacrylamide kufuna ingqalelo impembelelo utshintsho lwemozulu (ubushushu) ekukhetheni flocculant, ukukhetha ubunzima molekyuli ezifanelekileyo kunye nexabiso lentlawulo esekelwe ubungakanani floc efunwa yinkqubo unyango, kunye nezinye izinto. Ukongeza, kufuneka kunikwe ingqwalasela kwimiba efana nenkqubo kunye neemfuno zezixhobo kunye nokusetyenziswa kweeflocculants.
Kumanzi amdaka e-elektroniki kunye ne-electroplating, i-PAM isetyenziswa kakhulu njengeI-Flocculantkunye ne-precipitant. Ngokunciphisa iipropathi zombane kunye nokusebenzisa i-adsorbing bridging effects, i-PAM inokukhawuleza idibanise kwaye ihlalise ii-ion zentsimbi enzima kumanzi amdaka. Kule nkqubo, ngokuqhelekileyo kuyimfuneko yokongeza i-asidi ye-sulfuric kumanzi amdaka ukulungelelanisa ixabiso le-pH kwi-2-3 kwaye wongeze i-agent yokunciphisa. Kwitanki yokusabela elandelayo, sebenzisa i-NaOH okanye i-Ca (OH) 2 ukulungisa ixabiso le-pH kwi-7-8 ukuvelisa i-Cr (OH) i-3 precipitates. Emva koko yongeza i-coagulant ukumisa kwaye ususe i-Cr(OH)3. Ngokusebenzisa ezi nkqubo zonyango, i-PAM inceda ekuphuculeni ukusebenza kakuhle kwe-electronic kunye ne-electroplating unyango lwamanzi amdaka kunye nokunciphisa umonakalo wee-ion zensimbi ezinzima kwindalo.
