Polyacrylamide iri mutsetse wepolymer, chigadzirwa chacho chinonyanya kukamurwa kuita hupfu hwakaoma uye colloidal mafomu maviri. Zvinoenderana neavhareji yehuremu hwema molecular, inogona kukamurwa kuita yakaderera molecular uremu (<1 miriyoni), yepakati molecular uremu (2 ~ 4 miriyoni) uye yakakwirira molecular uremu (> .7 miriyoni) .Maererano nechimiro chayo chinogona kukamurwa kuita zvisiri izvo. - ionic, anion uye cationic. Kuparara kwemvura (HPAM) yeanion type. Cheni huru yepolyacrylamide ine nhamba huru yemapoka e-amide, ane maitiro emakemikari akakwira, uye anogona kugadziridzwa kuti abudise akawanda anobva papolyacrylamide. Zvigadzirwa zvave zvichishandiswa zvakanyanya mukugadzira mapepa, mineral processing, kudhirowa kwemafuta, metallurgy, zvekuvakisa, kurapwa kwetsvina uye mamwe maindasitiri. Semafuta ekuzora, kumiswa mumiririri, ivhu stabilizer, oiri inotamisa mumiriri, kurasikirwa kwemvura inodzikisira mumiririri uye thickening mumiririri, polyacrylamide yakashandiswa zvakanyanya mukuchera, acidification, fracturing, plugging mvura, simende, kudzoreredza mafuta echipiri uye kudzoreredza mafuta epamusoro.

Application

1.kudhinda uye kudhaya tsvina yemvura

Kudhinda uye kudhayira kurapwa kwemvura yetsvina, panzvimbo pechinyakare yakaderera mamorekuru coagulants, zvine chekuita neyakakura dosage yecoagulant, iyo coagulation inoshanda yakakwira, optimum ph mamiriro anotevera: 8.0.

2.Papermaking wastewater treatment

Papermaking wastewater treatment, iyo inoshandiswa se coagulant pachinzvimbo che polyaluminium chloride, aluminium sulfate, nezvimwewo, inogona kushandiswawo sedewatering of papermaking sludge.
