Anionic polyacrylamide e haholo-holo sebelisoa bakeng sa ho matlafatsa flocculation ea likhoerekhoere, e na le litšobotsi tsa polymer electrolyte ka ho se nke lehlakore le alkaline seaplane, nahanela ho electrolyte letsoai, 'me theko e phahameng ions tšepe ka sefapanong amahanngoa le insoluble gel, e leng haholo-holo sebelisoa bakeng sa tlhahiso ea malapeng. metsi, liindasteri le teropo ea likhoerekhoere kalafo, 'me e ka boela sebelisoa bakeng sa inorganic sludge dehydration.
Libaka tse tharo tsa mantlha tsa ts'ebeliso ea anionic polyacrylamide:
Ka indasteri ea tlhahiso ea tšepe le tšepe, e sebelisoa bakeng sa tlhoekiso ea metsi a hlatsoang khase ka seboping se bulehileng, ho hlakisoa ha metsi a litšila ka limela tsa metallurgy le limela tsa pickling, tlhoekiso ea li-electrolyte le ho hlakisoa ha metsi a litšila a electroplating.
Merafong, e sebelisetsoa ho hlakisa metsi a mashala le mehatla ea flotation, ho hloekisa mashala a hloekileng, tailings (slag) dehydration, flotation tailings clarification, concentrate thickening le filtration, potassium alkali hot melt le flotation processing fluid clarification, fluorite le barite flotation clarification tailings. , brine e tala bakeng sa ts'ebetso ea letsoai, ho hlakisoa ha sludge dehydration le kalafo ea metsi ea ho khutlisa morafo oa phosphate.
Ho hloekisa metsi a litšila litoropong le indastering, e sebelisetsoa ho ntlafatsa ho tlosoa ha lintho tse tiileng tse emisitsoeng, BOD le phosphate metsing a litšila.Ka ho eketsa 0.25mg / L hydrolyzed polyacrylamide ho tanka ea mantlha ea metsi a litšila, litekanyetso tsa ho tlosoa ha taba e emisitsoeng le BOD li ka eketsoa ho 66% le 23%, ka ho latellana.Ka ho eketsa 0.3mg/L anionic polyacrylamide ho tanka ea sedimentation ea metsi a litšila ea bobeli, tekanyo ea ho tlosoa ha taba e emisitsoeng le BOD e ka eketsoa ho 87% le 91%, ka ho latellana, le phello ea ho tlosoa ha phosphorus e ka eketseha ho tloha ho 35% ho ea ho 91%. .Ha ho phekoloa metsi a nooang le metsi a litšila a malapeng, a sebelisetsoa ho hlakisa holim'a metsi, ho hlakisa metsi a litšila le ho fetola filtrate.
Ho hlahisoa ha solubility ea anionic polyacrylamide:
1, e sebelisoang sebakeng sa likhoerekhoere, tekanyo e khothaletsoang ea 0.1%
2, pele u fafatsa phofo ka metsing a pompo, 'me u tsose ka lebelo le bohareng la 40-60 RPM ho etsa hore polymer e qhibilihe ka ho feletseng metsing pele e ka eketsoa.
3, Nakong ea teko, nka metsi a litšila a 100ml, eketsa 10% ea tharollo ea polyacrylamide, 'me butle-butle u tsose, sebelisa seringe ho eketsa butle-butle tharollo ea PAM, 0.5ml nako le nako, ho ea ka boholo ba palesa ea alum e entsoeng le ho ba haufi ha flocculant, ho hlaka ha supernitant, sekhahla sa sedimentation, tekanyo ea ho fumana moemeli ea loketseng.
