Yintoni ipholima?
Iipolymerszizinto ezenziwe ngeemolekyuli ezidityanisiweyo ngamatyathanga.Ezi khonkco zihlala zide kwaye zinokuphinda ziphindwe ukwandisa ubungakanani besakhiwo se-molecular.Iimolekyuli zomntu ngamnye kwikhonkco zibizwa ngokuba yi-monomers, kwaye i-chain structure ingenziwa ngesandla okanye iguqulwe ukuze ifezekise iipropati kunye neepropati ezithile.
Ukwenziwa kodongwe oluneenjongo ezininzi kukusetyenziswa kwezakhiwo ze-polymer molecular modified.Kweli nqaku, nangona kunjalo, siza kugxila kwiipolymers kwishishini,ngokukodwa unyango lwamanzi lwepolymer.
Iipholima zingasetyenziswa njani kunyango lwamanzi?
Iipolymers ziluncedo kakhulu kunyango lwamanzi amdaka.Ngengqiqo esisiseko, indima yala matsheyina emolekyuli kukwahlula icandelo eliqinileyo lamanzi amdaka kulwelo lwawo.Emva kokuba amacandelo amabini amanzi amdaka ahluliwe, kulula ukugqibezela inkqubo ngokwahlula okuqinileyo kunye nokunyanga ulwelo, ukushiya amanzi acocekileyo ukuze alahlwe ngokukhuselekileyo okanye kwezinye izicelo zemizi-mveliso.
Ngale ndlela, i-polymer yi-flocculant - into esebenza kunye nezinto eziqinileyo ezixhonywe emanzini ukuze zenze i-clumps ebizwa ngokuba yi-floc.Oku kuluncedo kakhulu kwiinkqubo zokucocwa kwamanzi amdaka, ngoko ke iipholima zihlala zisetyenziswa zodwa ukwenza i-flocculation, enokuthi isuse ngokulula izinto eziqinileyo.Nangona kunjalo, ukuze ufumane iziphumo ezilungileyo kule nkqubo, ii-polymer flocculants zihlala zisetyenziswa kunye ne-coagulants.
Iicoagulants zithatha inkqubo yeflocculation ziye kwinqanaba elilandelayo, ziqokelela iiflocs kunye zenza umaleko oshinyeneyo wodaka olunokuthi emva koko lususwe okanye lunyangwe ngakumbi.I-Polymer flocculation ingenzeka ngaphambi kokongezwa kwe-coagulants okanye ingasetyenziselwa ukukhawulezisa inkqubo ye-electrocoagulation.Ngenxa yokuba i-electrocoagulation inezo zombini iingenelo kunye nezingeloncedo, ukusetyenziswa kwee-polymer flocculants ukwandisa inkqubo sisindululo esinomtsalane kubaphathi beziko.
Iindidi ezahlukeneyo zeepolima zonyango lwamanzi
Ukucocwa kwamanzi epolymer kunokusebenza ngeendlela ezahlukeneyo kuxhomekeke kuhlobo lwemonomer esetyenziselwa ukwenza ikhonkco lepolymer.Iipolymers ngokubanzi ziwela kwiindidi ezimbini ezibanzi.Ziyi-cationic kunye ne-anionic, zibhekiselele kwiintlawulo ezihambelanayo zamatyathanga e-molecular.
Iipolymers zeAnionic kunyango lwamanzi
Iipolymers zeAnionic zihlawuliswa kakubi.Oku kubenza bafaneleke ngokukodwa ukudada kwizinto eziqinileyo ezingaphiliyo, ezinjengodongwe, intlenga yentlenga okanye ezinye iintlobo zomhlaba, kwizicombululo zenkunkuma.Amanzi amdaka avela kwiiprojekthi zemigodi okanye ishishini elinzima linokuba sisityebi kulo mxholo uqinileyo, ngoko ke iipolymers zeanionic zinokuba luncedo ngakumbi kwezo zicelo.
Iipolymers zeCation kunyango lwamanzi
Ngokubhekiselele kwintlawulo yayo ehambelanayo, i-polymer ye-cationic ngokusisiseko ichasene ne-anionic polymer kuba inentlawulo efanelekileyo.Intlawulo efanelekileyo yeepolymers ze-cationic zibenza zilungele ukususa izinto eziqinileyo ze-organic kwizisombululo zamanzi amdaka okanye imixube.Ngenxa yokuba imibhobho yogutyulo lwamanzi amdaka ithande ukuqulatha izixa ezikhulu zezinto eziphilayo, iipolymers zecationic zihlala zisetyenziswa kwiindawo zokucocwa kwamanzi amdaka zikamasipala, nangona amaziko ezolimo kunye nokulungiswa kokutya nawo asebenzisa ezi polima.
Iipolymers ze-cationic eziqhelekileyo ziquka:
Ipolydimethyl diallyl ammonium chloride, polyamine, polyacrylic acid/sodium polyacrylate, cationic polyacrylamide, njl.
