Polyacrylamide kugadzirwa maitiroinosanganisira batching, polymerization, granulation, kuomesa, kutonhora, kupwanya uye kurongedza.Iyo yakasvibirira inopinda muketani yedosing kuburikidza nepombi, ichiwedzera izvo zvinopindirana kuti zvisanganise zvakaenzana, kutonhora kusvika 0-5 ℃, iyo mbishi inotumirwa kune polymerization kettle kuburikidza nenitrogen deoxygenation, okisijeni yemukati inoderedzwa kusvika 1%, wedzera initiator yepolymerization, mushure mekuita polymerization, iyo rubber block inochekwa, inotumirwa kune pelletizer ye granulation, granulated pellets inotumirwa kumubhedha wekuomesa kuti aome.Iyo yakaomeswa zvinhu inotumirwa kune yekupwanya uye yekuongorora system yekupwanya.Mushure mekupwanya, zvinhu zvinopinda mupakeji system yekurongedza uye inoumba chigadzirwa chakapedzwa.

Monomer kugadzira nzira
Kugadzirwa kwe acrylamide monoma kunobva pa acrylonitrile seyakabikwa, pasi pekuita kwecatalyst hydration kuti ibudise crude product ye acrylamide monomer, mushure me flash distillation, yakanatswa acrylamide monoma, monoma iyi ndiyo mbishi yekugadzirwa kwe poly444 acrylamide.
Acrylonitrile + (inogadzirisa mvura/mvura) → yakasanganiswa → crude acrylamide → flash → yakanatswa → yakanatswa acrylamide.
Polyacrylamide aqueous mhinduro inoshandiswa seyakagadzirwa zvinhu kugadzirwa.Pasi pekuita kwekutanga, polymerization reaction inoitwa.Mushure mekuita kwapera, iyo polyacrylamide gum block inogadzirwa, inochekwa, yakaomeswa uye yakapwanyika, uye pakupedzisira chigadzirwa chepolyacrylamide chinogadzirwa.Iyo yakakosha maitiro ndeye polymerization.Muchinotevera kurapa kwacho, kutarisisa kunofanirwa kubhadharwa kune mechanic kutonhora, kupisa kwekupisa uye crosslinking, kuitira kuti ive nechokwadi chehukama molecular uremu uye solubility yemvura yepolyacrylamide.
Acrylamide+ mvura (yekutanga/polymerization) → polyacrylamide chingamu block → granulation → kuomesa → kupwanya → polyacrylamide chigadzirwa
