Polyacrylamide Molecular Water Treatment Chemicals

I-Polyacrylamide (PAM) ligama eliqhelekileyo le-acrylamide homopolymer okanye i-copolymerized kunye nezinye ii-monomers, kwaye yenye yezona ntlobo zisetyenziswa kakhulu kwiipolima ezinyibilikayo emanzini.Ngenxa yokuba iyunithi yesakhiwo se-polyacrylamide iqulethe amaqela e-amide, kulula ukwenza iibhondi ze-hydrogen, ezenza zibe nokunyibilika kakuhle kwamanzi kunye nomsebenzi ophezulu wemichiza, kwaye kulula ukufumana izilungiso ezahlukeneyo ze-branched chain okanye isakhiwo sothungelwano ngokuxhunyelelwa okanye ukudibanisa., Isetyenziselwa ngokubanzi ukuhlola i-petroleum, unyango lwamanzi, i-textile, i-papermaking, i-mineral processing, iyeza, ezolimo kunye namanye amashishini, kwaye yaziwa ngokuba "ngabancedisi kuwo onke amashishini".Iinkalo zesicelo eziphambili kumazwe angaphandle kunyango lwamanzi, ukwenza iphepha, imigodi, i-metallurgy, njl.;e-China, elona xabiso likhulu ngoku lisetyenziswa kwintsimi yokutsalwa kweoli, kwaye amasimi akhula ngokukhawuleza akwiindawo zokucocwa kwamanzi kunye nokwenza iphepha.

Indawo yokucoca amanzi:

Ukucocwa kwamanzi kubandakanya ukucocwa kwamanzi akrwada, ukucocwa kogutyulo kunye nokucocwa kwamanzi kwimizi-mveliso.Isetyenziswe ngokubambisana nekhabhoni esebenzayo kunyango lwamanzi akrwada, ingasetyenziselwa i-coagulation kunye nokucaciswa kwamasuntswana amisiweyo kumanzi asekhaya.Ukusetyenziswa kwe-organic flocculant acrylamide endaweni ye-inorganic flocculant inokunyusa umthamo wokucoca amanzi ngaphezu kwe-20% nangaphandle kokuguqula itanki yokumisa;kunyango lwamanzi amdaka, ukusetyenziswa kwepolyacrylamide kunokonyusa izinga lokusetyenziswa kokuphinda kusetyenziswe amanzi kwakhona kwaye kunokusetyenziswa njengokucocwa kodaka;isetyenziswe njenge-arhente ebalulekileyo yokuqulunqa kunyango lwamanzi oshishino.Intsimi enkulu yokusetyenziswa kwe-polyacrylamide phesheya kukunyanga kwamanzi, kwaye isicelo kule ntsimi e-China siyakhuthazwa.Indima ephambili ye-polyacrylamide kunyango lwamanzi: [2]
(1) Ukunciphisa inani le-flocculant.Ngaphantsi kwesiseko sokufikelela umgangatho ofanayo wamanzi, i-polyacrylamide isetyenziswa njenge-coagulant aid ngokudibanisa nezinye iiflocculants, ezinokunciphisa kakhulu inani le-flocculant esetyenziswayo;(2) Ukuphucula umgangatho wamanzi.Kunyango lwamanzi okusela kunye nokunyangwa kwamanzi amdaka kwimizi-mveliso, ukusetyenziswa kwe-polyacrylamide ngokudibanisa ne-inorganic flocculants kunokuphucula kakhulu umgangatho wamanzi;(3) Ukwandisa amandla e-floc kunye nesantya sentlenga.I-flocs eyenziwe yi-polyacrylamide inamandla aphezulu kunye nokusebenza kakuhle kwentlenga, ngaloo ndlela yandisa isantya sokwahlukana okuqinileyo kunye nokuququzelela ukuchithwa kwe-sludge;(4) I-Anti-corrosion kunye ne-anti-scaling yenkqubo yokupholisa ejikelezayo.Ukusetyenziswa kwe-polyacrylamide kunokunciphisa kakhulu ubungakanani be-flocculants ye-inorganic, ngaloo ndlela kunqandwa ukubekwa kwezinto ezingaphili kumphezulu wezixhobo kunye nokucotha ukubola kunye nokunyuka kwezixhobo.

I-Polyacrylamide isetyenziswa ngokubanzi njengoncedo lokugcina, uncedo lokucoca, i-arhente yokulinganisa, njl njl kwintsimi yokwenza iphepha ukuphucula umgangatho wephepha, ukusebenza kwe-slurry dehydration, izinga lokugcinwa kwemicu emihle kunye nezihluzi, ukunciphisa ukusetyenziswa kwezinto eziluhlaza kunye nongcoliseko lokusingqongileyo, Isetyenziswa njenge-dispersant ukuphucula ukufana kwephepha.I-Polyacrylamide isetyenziswa ikakhulu kwimiba emibini kushishino lwephepha.Enye kukunyusa izinga lokugcinwa kweefayili kunye ne-pigments ukunciphisa ilahleko yezinto eziluhlaza kunye nongcoliseko lwendalo;enye kukwandisa amandla ephepha.Ukongeza i-polyacrylamide kwizinto eziphathekayo zephepha kunokunyusa izinga lokugcinwa kweefayili ezintle kunye neengqungquthela zokuzalisa kumnatha kunye nokukhawulezisa ukuchithwa kwempahla yephepha.Inkqubo yesenzo se-polyacrylamide kukuba amasuntswana akuludaka ajikeleziswa kwaye agcinwe kwilaphu lokucoca ngokungathathi hlangothi okanye ngokubopha ibhulorho.Ukubunjwa kweeflocs kunokwenza ukuba kube lula ukuhluza amanzi kwi-slurry, ukunciphisa ilahleko yeentsinga kumanzi amhlophe, ukunciphisa ukungcoliseka kwendalo, kunye nokunceda ukuphucula ukusebenza kakuhle kokucoca kunye nezixhobo ze-sedimentation.
