I-polyether polyurethane acrylate yezingubo zepulasitiki

Ikhodi yomkhiqizo: ZC6202

Umkhiqizo we-ZC6202 uwumkhiqizo womkhiqizo wenkampani.Igama layo lamakhemikhali yi-polyether polyurethane acrylate.Iwuketshezi olungenambala noma oluphuzi olusobala olunokuguquguquka okuhle nokunamathela.Isetshenziselwa ikakhulukazi iphepha, ukugqoka kwepulasitiki kanye ne-primer yokunamathisela ngokhuni.I-aromatic polyurethane acrylate

Engeza i-polyester (i-polyester) i-diol kanye ne-polymerization inhibitor ku-flask ye-port emine efakwe umshini oshukumisayo, izinga lokushisa kanye ne-condenser tube, ugovuze ngokulinganayo, bese ufaka i-TDI, ukhuphule izinga lokushisa libe ku-70-80 ℃ ukuze uphendule amahora angu-1.5, thola inani le-NCO, bese wengeza i-hydroxyethyl acrylate (i-hydroxypropyl acrylate), engeza i-catalyst, qhubeka nokusabela amahora angu-3, ​​futhi uthole ukuthi inani le-NCO lilingana no-0. I-viscosity ye-aromatic polyurethane acrylate ikalwe ngesampula, futhi ukusebenza kwe-polyurethane acrylate enamakha kwahlolwa. ngokwengeza u-3% - 4% we-photoinitiato.Sicela ugcine indawo epholile noma eyomile, futhi ugweme ilanga nokushisa;Izinga lokushisa lesitoreji alidluli ku-40 ºC, izimo zokulondoloza ngaphansi kwezimo ezijwayelekile okungenani izinyanga ezingu-6.

Iqaliswe nge-polyethylene glycol (PEG, MW 1000) ε- Caprolactone ( ε- Ingxenye ethambile ye-polyether ester block copolymer diol (pCEC) yalungiswa ngokuvula indandatho, yasabela nge-diisocyanate (toluene diisocyanate noma i-diphenylmethane diisocyanate, metha hydroxylateth, metha hydroxylateth, metha hydroxylate, metha hydroxylate). yelashwe ukuze kutholwe i-polyether ester polyurethane acrylate material (PUA) Ukwakheka nokwakheka kwe-PUA kuphawulwe Imiphumela ibonisa ukuthi ukwanda kwengxenye ye-PCL kungathuthukisa icrystallinity yezinto ze-PUA, kodwa kunciphise izinga lokumuncwa nokuwohloka kwamanzi Izinga le-enzymatic hydrolysis ye-PUA laliphezulu. kunaleyo ye-PUA Pcec2000-tdi impahla ine-hydrophilicity enhle kakhulu nokusebenza kokuwohloka.Ukumuncwa kwamanzi kuphezulu njenge-65.24% emahoreni angu-72 futhi kungonakalisa ngokuphelele isisombululo se-enzyme phakathi kwamasonto angu-11 Lolu hlobo lwezinto ze-PUA lunamandla okusetshenziswa ezintweni zobunjiniyela bezicubu.
