Kusanthula kwaukadaulo wopanga polyacrylamide

Njira yopanga Polyacrylamidekumaphatikizapo batching, polymerization, granulation, kuyanika, kuzizira, kuphwanya ndi kuyika. Zopangira zimalowa mu ketulo ya dosing kudzera mu payipi, ndikuwonjezera zowonjezera zofananira kuti zisakanizike, kuzirala mpaka 0-5 ℃, zopangira zimatumizidwa ku ketulo ya polymerization kudzera mu nayitrogeni deoxygenation, zomwe zili ndi mpweya zimachepetsedwa mpaka 1%, onjezerani kuyambitsa kwa polymerization, pambuyo polima, chipika cha mphira chimadulidwa, chimatumizidwa ku pelletizer kwa granulation, ma pellets a granulated amatumizidwa ku bedi loyanika. za kuyanika. Zinthu zouma zimatumizidwa ku dongosolo lophwanyidwa ndi kuwunikira kuti liphwanyidwe. Pambuyo kuphwanya, zinthuzo zimalowa m'mapaketi kuti zisungidwe ndikupanga chinthu chomalizidwa.

Njira yopanga monomer

Kupanga acrylamide monoma zachokera acrylonitrile monga zopangira, pansi pa zochita za chothandizira hydration kubala yaiwisi mankhwala acrylamide monoma, pambuyo kung'anima distillation, woyengeka acrylamide monoma, monoma izi ndi zopangira kupanga poly444 acrylamide.

Acrylonitrile + (chothandizira madzi/madzi) → chophatikizidwa → acrylamide osakhwima → kung'anima → oyeretsedwa → oyeretsedwa acrylamide.

teknoloji ya polymerization

Polyacrylamide amadzimadzi njira ntchito ngati zopangira kupanga. Pansi pa zochita za initiator, polymerization reaction ikuchitika. Zomwezo zikamalizidwa, chipika cha chingamu cha Polyacrylamide chimadulidwa, granulated, zouma ndi kuphwanyidwa, ndipo pamapeto pake mankhwala a polyacrylamide amakonzedwa. Njira yofunika kwambiri ndi polymerization. Mu wotsatira ndondomeko ya mankhwala, chidwi ayenera kuperekedwa kwa makina kuzirala, kuwonongeka matenthedwe ndi crosslinking, kuti kuonetsetsa wachibale maselo kulemera ndi solubility madzi a Polyacrylamide.

Acrylamide+ madzi (woyambitsa/polymerization) → polyacrylamide chingamu chipika → granulation → kuyanika → kuphwanya → polyacrylamide mankhwala
