Uhlalutyo lweteknoloji yokuvelisa i-polyacrylamide

Inkqubo yokuvelisa iPolyacrylamidekubandakanya ukudibanisa, ukupholisa, ukugranula, ukomisa, ukupholisa, ukutyumza kunye nokupakishwa. Izinto ezikrwada zingena kwiketile yedosi ngombhobho, zongeza izongezo ezihambelanayo ukuxuba ngokulinganayo, ukupholisa ukuya kwi-0-5 ℃, imathiriyeli ekrwada ithunyelwa kwiketile yepolymerization nge-nitrogen deoxygenation, umxholo weoksijini uyancitshiswa ukuya malunga ne-1%, yongeza umqalisi wepolymerization, emva kwepolymerization, ibhloko yerabha inqunyulwe, ithunyelwe kwi-pelletizer ye-granulation, iipellets ezixubileyo zithunyelwe kwibhedi yokomisa. zokomisa. Izinto ezomileyo zithunyelwa kwinkqubo yokutyumza kunye nokuhlola ukutyumza. Emva kokutyumza, izinto eziphathekayo zingena kwinkqubo yokupakisha yokupakisha kwaye yenze imveliso egqityiweyo.

Polyacrylamideinkqubo yemveliso inamanyathelo amabini

Ubuchule bokuvelisa iMonomer

Ukuveliswa kwe-acrylamide monoma kusekelwe kwi-acrylonitrile njengento ekrwada, phantsi kwesenzo se-catalyst hydration ukuvelisa imveliso ekrwada ye-acrylamide monoma, emva kwe-flash distillation, i-acrylamide monoma esulungekileyo, le monoma yinto ekrwada yokuveliswa kwe-poly444 acrylamide.

I-Acrylonitrile + (i-catalyst yamanzi/amanzi) → idityanisiwe → i-acrylamide ekrwada → iflash → esulungekisiweyo → i-acrylamide esulungekileyo.

iteknoloji yepolymerization

Isisombululo samanzi sePolyacrylamide sisetyenziswa njengento ekrwada kwimveliso. Ngaphantsi kwesenzo somqalisi, ukuphendulwa kwepolymerization kuyenziwa. Emva kokuba impendulo igqityiwe, i-polyacrylamide gum block eyenziwayo iyasikwa, ihlulwe, yomiswe kwaye icunyuzwe, kwaye ekugqibeleni imveliso ye-polyacrylamide ilungisiwe. Inkqubo ephambili yipolymerization. Kwinkqubo yonyango elandelayo, kufuneka kuqwalaselwe ukupholisa ngoomatshini, ukuthotywa kwe-thermal kunye nokuphambana, ukuze kuqinisekiswe ubunzima bemolekyuli kunye nokunyibilika kwamanzi kwepolyacrylamide.

Acrylamide+ amanzi (umqalisi/ipolymerization) → ibhloko yentsika ye-polyacrylamide → igranulation → ukomisa → ukutyumza → imveliso yepolyacrylamide
