I-PAM yonyango lwamanzi
Intshayelelo
I-PAM (i-Polyacrylamide) luhlobo lwepolymer esetyenziswa kwizicelo ezahlukeneyo, kubandakanywa unyango lwamanzi.I-Polyacrylamide idla ngokusetyenziswa njenge-flocculant kwiinkqubo zokunyanga amanzi ukuphucula ukulungiswa kwamasuntswana amisiweyo, okwenza kube lula ukwahlula izinto eziqinileyo emanzini.
I-Polyacrylamide (PAM) yi-polymer compound esetyenziswa ngokubanzi kwintsimi yonyango lwamanzi.Iza kwiindidi ezininzi ezahlukeneyo, kubandakanya i-nonionic, i-cationic, kunye ne-anionic.

Usetyenziso
I-Floculant:I-Polyacrylamide isoloko isetyenziswa njenge-flocculant kunyango lwamanzi ukususa izinto eziqinileyo ezimisiweyo, i-particulate matter kunye ne-colloids kwaye zijike zibe yiflocs ezinkulu ukuququzelela intlenga okanye ukuhluzwa okulandelayo.Le flocculation inceda ekuphuculeni ukucaca kwamanzi kunye nokungafihli.
Isichazi esinamandla:I-Polyacrylamide inokwenza ii-complexes kunye ne-ion zetsimbi ukuphucula umphumo we-precipitant.Xa uphatha amanzi amdaka aqukethe i-ion zetsimbi, ukusetyenziswa kwe-polyacrylamide kunokuphucula umphumo wemvula kunye nokunciphisa umxholo wee-ion zetsimbi kumanzi amdaka.
I-Antiscaant:Kwinkqubo yokucoca amanzi, i-polyacrylamide ingasetyenziselwa njengesithinteli sokulinganisa ukuthintela ukunyusa kumphezulu wemibhobho kunye nezixhobo.Iphucula ibhalansi ye-ion yamanzi, inqanda ukuchithwa kwezinto ezichithwe emanzini, kwaye inciphisa ukubunjwa kwesikali.
Ukuphuculwa komgangatho wamanzi:I-Polyacrylamide ingasetyenziselwa ukuphucula umgangatho wamanzi kwezinye iimeko, ezifana nokunyusa izinga lentlenga yezinto eziqinileyo emanzini, ukunciphisa ukubunjwa kodaka, njl.
Ukuqina komhlaba:Ekuqinisweni nasekuphuculweni komhlaba, i-polyacrylamide ingasetyenziselwa ukuphucula uzinzo kunye nokumelana nokubola komhlaba, ngaloo ndlela kuphuculwe iimpawu ezibonakalayo zomhlaba.
Kufuneka kuqatshelwe ukuba idosi ye-polyacrylamide kufuneka ilawulwe ngononophelo ngexesha lokusetyenziswa ukuphepha iziphumo ezibi kokusingqongileyo.Ukongezelela, isicelo esithile sixhomekeke kwiimfuno ezithile zonyango lwamanzi kunye neempawu zomgangatho wamanzi.
