Maemo a phetolo bakeng sa lits'ebetso tsa anionic polyacrylamide

Anionic polyacrylamide e sebediswa haholoholo bakeng sa ho matlafatsa ho phaphamala ha metsi a dikgwerekgwere, e na le dibopeho tsa polymer electrolyte moyeng o sa nke lehlakore le wa alkaline, e na le kutloelo-bohloko ho di-electrolyte tsa letsoai, mme di-ion tsa tshepe tse theko e hodimo di ka hokahanngwa le gel e sa qhibiliheng, e sebediswang haholoholo bakeng sa tlhahiso ya metsi malapeng, kalafo ya dikgwerekgwere tsa diindasteri le tsa ditoropo, mme e ka sebediswa hape bakeng sa ho fellwa ke metsi ha metsi a sa tswakanngwang.

Libaka tse tharo tse ka sehloohong tsa ts'ebeliso ea polyacrylamide ea anionic:

Indastering ea tlhahiso ea ho lahla le tšepe, e sebelisetsoa ho hloekisa metsi a hlatsoang khase ka ontong e bulehileng ea mollo, ho hlakisa metsi a litšila lifemeng tsa tšepe ea phofo le lifemeng tsa ho pickling, ho hloekisa li-electrolyte le ho hlakisa metsi a litšila a electroplating.

Merafong, e sebediswa bakeng sa ho hlatswa metsi a hlatswang mashala le ho phaphamala ha metsi, ho hlwekisa mashala a hlwekileng, ho fellwa ke metsi ha metsi (slag), ho hlakisa mashala a flotation, ho teteana le ho sefa, ho hlakisa mokelikeli o qhibilihiswang le ho hlophiswa ha metsi ka ho tjhesa potassium alkali, ho hlakisa mashala a flotation a fluorite le barite, brine e tala bakeng sa ho sebetsana le letswai, ho hlakisa ho fellwa ke metsi ha metsi ka lebaka la seretse le kalafo ya metsi a ho kgutlisa merafo ya phosphate.

Kalafong ea metsi a litšila a litoropong le indastering, e sebelisoa ho ntlafatsa ho tlosoa ha lintho tse tiileng tse emisitsoeng, BOD le phosphate metsing a litšila. Ka ho eketsa 0.25mg/L polyacrylamide e nang le hydrolyzed ho tanka ea mantlha ea sedimentation ea metsi a litšila, sekhahla sa ho tlosoa ha lintho tse emisitsoeng le BOD se ka eketsoa ho 66% le 23%, ka ho latellana. Ka ho eketsa 0.3mg/L anionic polyacrylamide ho tanka ea bobeli ea sedimentation ea kalafo ea metsi a litšila, sekhahla sa ho tlosoa ha lintho tse emisitsoeng le BOD se ka eketsoa ho 87% le 91%, ka ho latellana, 'me phello ea ho tlosoa ha phosphorus e ka eketsoa ho tloha ho 35% ho isa ho 91%. Kalafong ea metsi a nooang le metsi a litšila a malapeng, e sebelisoa bakeng sa ho hlakisa bokaholimo, ho hlakisa metsi a litšila a ntšang metsi le ho lokisa sefiltara.

Ho qhibiliha ha tokisetso ea anionic polyacrylamide ho hlahisoa:

1, e sebelisoang ho aha likhoerekhoere, karolelano e khothaletsoang ea 0.1%

2, qala ka ho fafatsa phofo ka metsi a pompo ka ho lekana, 'me u hlohle ka lebelo le mahareng la 40-60 RPM ho etsa hore polymer e qhibilihe ka botlalo metsing pele e ka eketsoa.

3, Nakong ea teko, nka metsi a litšila a 100ml, eketsa tharollo ea polyacrylamide ea 10%, 'me u hlohle butle-butle, sebelisa syringe ho eketsa tharollo ea PAM butle-butle, 0.5ml nako le nako, ho latela boholo ba palesa ea alum e hlahisitsoeng le hore na flocculant e haufi hakae, ho hlaka ha supernitant, sekhahla sa sedimentation, tekanyo ea ho fumana moemeli ea loketseng.
