Te tukanga whakaputa polyacrylamidekei roto ko te puranga, te polymerization, te whakamaroke, te whakamaroke, te whakamatao, te kuru me te takai. Ko te rauemi mata ka uru ki roto i te kettle dosing i roto i te pipeline, ka taapirihia nga taapiri e rite ana ki te whakakotahi i te taurite, ka whakamatao ki te 0-5 ℃, ka tukuna te rauemi mata ki te kettle polymerization na roto i te hauota deoxygenation, ka heke te ihirangi hāora ki te 1%, ka taapirihia te kaitahuri mo te polymerization, i muri i te polymerization, ka tapatapahia te poraka rapa, ka tukuna ki te pelletizer maroke mo te whakamaroke mo te granulation. Ka tukuna nga mea kua maroke ki te kuru me te punaha tirotiro mo te kuru. I muri i te kuru, ka uru te rauemi ki te punaha kapi mo te kapi me te hanga i te hua kua oti.
PolyacrylamideE rua nga waahanga o te tukanga whakaputa
Hangarau hanga monomer
Ko te hanga o te monomer acrylamide kei runga i te acrylonitrile hei rauemi mata, i raro i te mahi a te hydration catalyst ki te whakaputa i te hua kino o te acrylamide monomer, i muri i te whakakorikori hiko, te monomer acrylamide parakore, ko tenei monomer te rauemi mata mo te hanga o te poly444 acrylamide.
Acrylonitrile + (whakatiki wai/wai) → whakakotahi → acrylamide masivesivá → uira → parakore → acrylamide parakore.
Ka whakamahia te wairewa wai polyacrylamide hei rauemi mata mo te hanga. I raro i te mahi a te kaitakawaenga, ka mahia te tauhohenga polymerization. I muri i te otinga o te tauhohenga, ka tapahia te poraka kapia polyacrylamide i hangaia, ka whakamarokehia, ka maroke, ka kuru, ka mutu ka rite te hua polyacrylamide. Ko te tukanga matua ko te polymerization. I roto i te tukanga maimoatanga e whai ake nei, me aro ki te whakamahana miihini, te whakahekenga waiariki me te honohono, kia pai ai te taumaha o te ngota ngota me te wairewa o te polyacrylamide.
Acrylamide+ wai (kaiwhakamahi/polymerization) → polyacrylamide gum poraka → granulation → whakamaroke → kuru → polyacrylamide hua
