Polyetherthane acrylate yo gutwikira plastike

Kode y'ibicuruzwa: ZC6202

Ibicuruzwa ZC6202 nibicuruzwa byikigo.Izina ryimiti ni polyether polyurethane acrylate.Nibintu bitagira ibara cyangwa umuhondo bisukuye neza kandi byoroshye guhinduka.Ikoreshwa cyane cyane kumpapuro, gutwikira plastike no gufata ibiti.Aromate polyurethane acrylate

Ongeramo polyether (polyester) diol na polymerisation inhibitor muri flask yicyambu ine ifite imashini ikurura, thermometer na tube ya kondenseri, koga neza, hanyuma wongereho TDI, uzamure ubushyuhe kuri 70-80 ℃ kugirango ubyakire mumasaha 1.5, menya agaciro ka NCO, hanyuma ongeraho hydroxyethyl acrylate (hydroxypropyl acrylate), ongeramo catalizator, ukomeze reaction kumasaha 3, hanyuma umenye ko agaciro ka NCO kangana na 0. Ubukonje bwa aromatic polyurethane acrylate bwapimwe nicyitegererezo, hanyuma hapimwa imikorere ya acurelate polyurethane aromatic wongeyeho 3% - 4% photoinitiato. Nyamuneka komeza ahantu hakonje cyangwa humye, kandi wirinde izuba nubushyuhe; ubushyuhe bwububiko ntiburenga 40 ºC, uburyo bwo kubika mubihe bisanzwe byibuze amezi 6.

Yatangijwe na polyethylene glycol (PEG, MW 1000) ε- Caprolactone （ε- Igice cyoroshye cya polyether ester block copolymer diol (pCEC) cyateguwe no gufungura impeta, gisubizwa na diisocyanate (toluene diisocyanate cyangwa diphenylmethane diisocyanate) na hydroxyethyl methacry yakize kugirango abone polyether ester polyurethane acrylate ibikoresho (PUA) Ibigize n'imiterere ya PUA byaranzwe Ibisubizo byerekana ko kongera igice cya PCL bishobora guteza imbere kristu yibikoresho bya PUA, ariko bikagabanya kwinjiza amazi no kwangirika Igipimo cya hydrolysis ya enzymatique ya PUA cyari hejuru kurenza ibya PUA Pcec2000-tdi ibikoresho bifite hydrophilique nziza kandi ikora nabi.Kwinjiza amazi ni hejuru ya 65.24% mumasaha 72 kandi birashobora kwangirika rwose mumuti wa enzyme mugihe cyibyumweru 11 Ubu bwoko bwa PUA bufite ubushobozi bwo gukoreshwa mubikoresho byubwubatsi.
