I-polyether polyurethane acrylate yokwaleka ngeplastiki

Ikhowudi yeMveliso: ZC6202

Imveliso ZC6202 yimveliso yophawu lwenkampani.Igama layo lekhemikhali yi-polyether polyurethane acrylate.Lulwelo olungenambala okanye olutyheli olucacileyo olunokuguquguquka okuhle kunye nokuncamathela.Isetyenziswa kakhulu kwiphepha, iplastiki yokugquma kunye ne-primer yokubambelela ngamaplanga.I-aromatic polyurethane acrylate

Yongeza i-polyester (i-polyester) i-diol kunye ne-polymerization inhibitor kwi-flask yezibuko ezine ezixhotyiswe ngomatshini oshukumisayo, i-thermometer kunye ne-condenser ityhubhu, ugxobhoze ngokulinganayo, uze udibanise i-TDI, uphakamise ubushushu ukuya kwi-70-80 ℃ yokusabela kwiiyure ze-1.5, fumana ixabiso le-NCO, emva koko ungeze i-hydroxyethyl acrylate (i-hydroxypropyl acrylate), yongeza i-catalyst, qhubeka usabela kwiiyure ze-3, kwaye ubone ukuba ixabiso le-NCO lilingana no-0. I-viscosity ye-aromatic polyurethane acrylate ilinganiswe ngesampuli, kunye nokusebenza kwe-aromatic polyurethane acrylate yavavanywa. ngokongeza i-3% - 4% photoinitiato.Nceda ugcine indawo epholileyo okanye eyomileyo, kwaye ugweme ilanga kunye nobushushu;Iqondo lokushisa lokugcina alidluli kuma-40 ºC, iimeko zokugcina phantsi kweemeko eziqhelekileyo ubuncinane kwiinyanga ezi-6.

Iqaliswe nge-polyethylene glycol (PEG, MW 1000) ε- Caprolactone ( ε- Icandelo elithambileyo le-polyether ester block copolymer diol (pCEC) yalungiswa ngokuvula iringi, yasabela nge-diisocyanate (i-toluene diisocyanate okanye i-diphenylmethane diisocyanate, kunye ne-diisocyanate) ukunyangwa ukufumana i-polyether ester polyurethane acrylate material (PUA) Ukubunjwa kunye nesakhiwo se-PUA zibonakaliswe Iziphumo zibonisa ukuba ukunyuka kwecandelo le-PCL kunokuphucula i-crystallinity yezinto ze-PUA, kodwa kunciphise izinga lokufunxa kwamanzi kunye nokuthotywa. kunaleyo ye-PUA Pcec2000-tdi imathiriyeli ine-hydrophilicity egqwesileyo kunye nokusebenza kokuthotywa.Ukuxutywa kwamanzi kuphezulu njenge-65.24% kwiiyure ze-72 kwaye kunokutshatyalaliswa ngokupheleleyo kwisisombululo se-enzyme kwiiveki ze-11 Olu hlobo lwezinto ze-PUA lunamandla okusetyenziswa kwizinto zobunjineli zezicubu.
