Tlhahlobo ea theknoloji ea tlhahiso ea polyacrylamide

Mokhoa oa tlhahiso ea Polyacrylamidee kenyelletsa ho becha, polymerization, granulation, ho omisa, ho pholisa, ho pshatla le ho paka.Lintho tse tala li kena ka kettle ea dosing ka phala, li eketsa li-additives ho kopanya ka mokhoa o ts'oanang, ho pholile ho 0-5 ℃, thepa e tala e romelloa ka kettle ea polymerization ka nitrogen deoxygenation, oksijene e fokotsehile hoo e ka bang 1%, eketsa initiator bakeng sa polymerization, ka mor'a hore polymerization, "rubber block" e khaotsoe, e rometsoe ho pelletizer bakeng sa granulation, li-pellets tse nang le granulated tse rometsoeng betheng ea ho omisa bakeng sa ho omisoa.Thepa e omisitsoeng e romelloa tsamaisong ea ho senya le ho hlahloba bakeng sa ho senya.Kamora ho sithabela, thepa e kenella ka har'a sistimi ea ho paka bakeng sa ho paka ebe e theha sehlahisoa se felileng.

Polyacrylamidets'ebetso ea tlhahiso e na le mehato e 'meli

Mokhoa oa tlhahiso ea monomer

Tlhahiso ea acrylamide monoma e thehiloe ho acrylonitrile e le lintho tse bonahalang tse tala, tlas'a ketso ea catalyst hydration ho hlahisa sehlahisoa se tala sa acrylamide monomer, ka mor'a hore ho be le distillation, e hloekisitsoeng acrylamide monoma, monoma ena ke thepa e tala bakeng sa tlhahiso ea poly444 acrylamide.

Acrylonitrile + (setšehetso sa metsi/metsi) → se kopantsoe → acrylamide e tala → flash → e hloekisitsoeng → acrylamide e hloekisitsoeng.

theknoloji ea polymerization

Polyacrylamide aqueous tharollo e sebelisoa e le thepa e tala bakeng sa tlhahiso.Tlas'a ketso ea initiator, karabelo ea polymerization e etsoa.Ka mor'a hore karabelo e phethoe, polyacrylamide gum block e hlahisoang e ea khaoloa, e granulated, e omisitsoe le ho siloa, 'me qetellong sehlahisoa sa polyacrylamide se lokisoa.Mokhoa oa bohlokoa ke polymerization.Ka mokhoa o latelang oa phekolo, tlhokomelo e lokela ho lefshoa ho pholiso ea mechine, ho senyeha ha mocheso le crosslinking, e le ho etsa bonnete ba hore boima ba limolek'hule le metsi a solubility ea polyacrylamide.

Acrylamide+ metsi (ho qala / polymerization) → polyacrylamide gum block → granulation → ho omisa → ho senya → sehlahisoa sa polyacrylamide
