Polyether polyurethane acrylate bakeng sa liphahlo tsa polasetiki

Khoutu ea lihlahisoa: ZC6202

Sehlahisoa sa ZC6202 ke sehlahisoa sa brand sa k'hamphani.Lebitso la eona la lik'hemik'hale ke polyether polyurethane acrylate.Ke mokelikeli o hlakileng o se nang 'mala kapa o mosehla o nang le ponahalo e ntle le ho khomarela.E sebelisoa haholo-holo bakeng sa pampiri, ho roala ka polasetiki le ho khomarela lehong.Monko o monate oa polyurethane acrylate

Kenya polyether (polyester) diol le polymerization inhibitor ka botlolong ea boema-kepe e mene e nang le mochini o susumetsang, thermometer le tube ea condenser, hlohlelletsa ka ho lekana, ebe o eketsa TDI, phahamisa mocheso ho 70-80 ℃ bakeng sa karabelo ea lihora tse 1.5, fumana boleng ba NCO, ebe u eketsa hydroxyethyl acrylate (hydroxypropyl acrylate), eketsa catalyst, tsoela pele ho itšoara ka lihora tsa 3, 'me u lemohe hore boleng ba NCO bo lekana le 0. The viscosity ea monko o monate oa polyurethane acrylate e ne e lekantsoe ka sampuli, 'me ts'ebetso ea monko o monate oa polyurethane acrylate e ile ea lekoa. ka ho eketsa 3% - 4% photoinitiato.Ka kopo, boloka sebaka se phodileng kapa se omileng, 'me u qobe letsatsi le mocheso;Mocheso oa polokelo ha o fete 40 ºC, maemo a polokelo tlas'a maemo a tloaelehileng bonyane likhoeli tse 6.

E qalisoa ka polyethylene glycol (PEG, MW 1000) ε- Caprolactone (ε- Karolo e bonolo ea polyether ester block copolymer diol (pCEC) e ile ea lokisoa ka ho buloa ha selikalikoe, ho arabela ka diisocyanate (toluene diisocyanate kapa diphenylmethane diisocyanate, metha hydroxylateth, metha hydroxylateth le methane hydroxylateth) Pheko ea ho fumana polyether ester polyurethane acrylate material (PUA) Sebopeho le sebopeho sa PUA li ne li khetholloa Liphetho li bontša hore karolo e ntseng e eketseha ea PCL e ka ntlafatsa crystallinity ea thepa ea PUA, empa ea fokotsa sekhahla sa ho monya le ho senyeha ha metsi Sekhahla sa enzymatic hydrolysis ea PUA se ne se le holimo. ho feta ea thepa ea PUA Pcec2000-tdi e na le hydrophilicity e ntle haholo le ts'ebetso ea ho senyeha.Monyetla oa metsi o ka holimo ho 65.24% ka lihora tse 72 'me o ka senyeha ka ho feletseng ka tharollo ea enzyme nakong ea libeke tse 11 Mofuta ona oa lisebelisoa tsa PUA o na le monyetla oa ho sebelisoa lisebelisoa tsa boenjiniere ba lisele.
