Kusanthula kwaukadaulo wopanga polyacrylamide

Njira yopanga Polyacrylamidekumaphatikizapo batching, polymerization, granulation, kuyanika, kuzizira, kuphwanya ndi kulongedza. The zopangira amalowa dosing ketulo mwa payipi, kuwonjezera zina lolingana kusakaniza wogawana, kuzirala kwa 0-5 ℃, zopangira amatumizidwa ku polymerization ketulo kudzera nayitrogeni deoxygenation, okhutira mpweya ndi yafupika pafupifupi 1%, kuwonjezera kuyambitsa kwa polymerization, pambuyo polymerization, chipika chipika ndi akanadulidwa, pellets bedi anatumiza kwa granules granulated granulated granulated granulated. 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
