Ukuhlaziywa kobuchwepheshe bokukhiqiza i-polyacrylamide

Inqubo yokukhiqiza i-Polyacrylamidekuhlanganisa ukuhlanganisa, ukwenza i-polymerization, i-granulation, ukomisa, ukupholisa, ukuchotshozwa nokupakisha.Impahla eluhlaza ingena eketela lokudosa ngepayipi, yengeza izithasiselo ezihambisanayo ukuze ixube ngokulinganayo, iphole ibe ngu-0-5 ℃, impahla eluhlaza ithunyelwa kugedlela le-polymerization nge-nitrogen deoxygenation, okuqukethwe kwe-oxygen kuncishiswe ku-1%, engeza i-initiator ye-polymerization, ngemva kwe-polymerization, i-rubber block iyasikwa, ithunyelwe ku-pelletizer ukuze i-granulation, ama-pellets ane-granulated athunyelwe embhedeni wokomisa ukuze omiswe.Izinto ezomile zithunyelwa ohlelweni lokuchotshozwa nokuhlola ukuze kugaywe.Ngemuva kokuchotshozwa, izinto zingena ohlelweni lokupakisha lokupakisha bese lwakha umkhiqizo oqediwe.

I-Polyacrylamideinqubo yokukhiqiza inezinyathelo ezimbili

Indlela yokukhiqiza ye-Monomer

Ukukhiqizwa kwe-acrylamide monoma kusekelwe ku-acrylonitrile njengempahla eluhlaza, ngaphansi kwesenzo se-catalyst hydration ukukhiqiza umkhiqizo ongahluziwe we-acrylamide monoma, emva kwe-flash distillation, i-acrylamide monomer elicwengekile, le monoma yimpahla eluhlaza yokukhiqizwa kwe-poly444 acrylamide.

I-Acrylonitrile + (i-catalyst/amanzi) → kuhlangene → i-acrylamide engahluziwe → iflash → ecwengisisiwe → i-acrylamide ecwengisisiwe.

ubuchwepheshe be-polymerization

Isixazululo samanzi sePolyacrylamide sisetshenziswa njengezinto ezingavuthiwe zokukhiqiza.Ngaphansi kwesenzo se-initiator, ukusabela kwe-polymerization kuyenziwa.Ngemva kokuqedwa kokusabela, i-polyacrylamide gum block ekhiqizwayo iyasikwa, igaywe, yomiswe futhi igaywe, futhi ekugcineni umkhiqizo we-polyacrylamide uyalungiswa.Inqubo eyinhloko i-polymerization.Esikhathini esilandelayo sokwelashwa, ukunakwa kufanele kukhokhwe ekupholiseni kwemishini, ukuwohloka kokushisa okushisayo kanye nokuxhumanisa, ukuze kuqinisekiswe isisindo samangqamuzana esihlobo kanye ne-solubility yamanzi ye-polyacrylamide.

I-Acrylamide+ amanzi (isiqalisi/i-polymerization) → i-polyacrylamide gum block → granulation → ukomisa → ukuchotshozwa → umkhiqizo we-polyacrylamide
