Vatsvagiri vakaona kuti kugadziridzwa kwe epoxy acrylate (EA) ine carboxyl-yakamiswa yepakati inowedzera kuchinjika kwefirimu uye inoderedza viscosity yeresin. Chidzidzo ichi zvakare chinoratidza kuti zvigadzirwa zvakashandiswa hazvidhure uye zvinowanikwa nyore.
Epoxy acrylate (EA) parizvino ndiyo inonyanya kushandiswa UV-inorapika oligomer nekuda kwenguva pfupi yekurapa kwayo, kuomarara kwekupfeka kwepamusoro, midziyo yakanaka kwazvo, uye kugadzikana kwekupisa. Kugadzirisa matambudziko ehutete hwepamusoro, kusachinja-chinja, uye viscosity yakakwirira yeEA, iyo UV-inorapika epoxy acrylate oligomer ine yakaderera viscosity uye yakakwirira kuchinjika yakagadziridzwa uye yakaiswa kune UV-inorapika coatings. Iyo carboxyl yakagumiswa yepakati yakawanikwa nekuita kweanhydride uye diol yakashandiswa kushandura EA kuti ivandudze kuchinjika kweyakapora firimu, uye kuchinjika kwakagadziriswa kuburikidza nehurefu hwekabhoni ketani ye diols.
Nekuda kwezvimiro zvavo zvakatanhamara, epoxy resins anoshandiswa zvakanyanya muindasitiri yekupfeka kupfuura chero imwe kirasi yebinder. Mubhuku ravo idzva rezvinyorwa "Epoxy Resins", vanyori Dornbusch, Kristu naRasing vanotsanangura nheyo dzekemikari yeboka re epoxy uye vanoshandisa maitiro chaiwo kutsanangura kushandiswa kwepoxy uye phenoxy resins muzvigadzirwa zvemaindasitiri - kusanganisira kudzivirira kuparara, pasi pasi, poda coatings uye mukati ma can coatings.
Iyo resin viscosity yakaderedzwa nekutsiva zvishoma E51 nebinary glycidyl ether. Kuenzaniswa neEA isina kugadziriswa, viscosity ye resin yakagadzirirwa muchidzidzo ichi inoderera kubva ku29800 kusvika ku13920 mPa s (25 ° C), uye kushanduka kwefirimu yakarapwa kunowedzera kubva ku12 kusvika ku1 mm. Zvichienzaniswa neyekutengesa inogadziridzwa EA, iyo mbishi inoshandiswa muchidzidzo ichi inodhura yakaderera uye iri nyore kuwana nekuita tembiricha iri pasi pe130 ° C, uchishandisa yakapusa synthesis process, uye hapana organic zvinonyungudutsa.
Iyi reserach yakaburitswa muChinyorwa cheCoatings Technology uye Tsvagiridzo, Vhoriyamu 21, muna Mbudzi 2023.
