Abashakashatsi basanze guhindura epoxy acrylate (EA) hamwe na carboxyl yarangiye hagati byongera ubworoherane bwa firime kandi bikagabanya ububobere bwa resin. Ubushakashatsi bugaragaza kandi ko ibikoresho fatizo bikoreshwa bidahenze kandi byoroshye kuboneka.
Epoxy acrylate (EA) kuri ubu niyo ikoreshwa cyane na UV-ishobora gukira oligomer kubera igihe gito cyo gukira, gukomera gukomeye, imitungo myiza yubukanishi, hamwe nubushyuhe bwumuriro. Kugira ngo hakemurwe ibibazo byubugome bukabije, guhinduka kwinshi, hamwe nubukonje bukabije bwa EA, hateguwe UV-ikiza epoxy acrylate oligomer ifite ubukonje buke kandi bworoshye cyane kandi byashyizwe mubikorwa bya UV-bivura. Carboxyl yarangije hagati yabonetse kubisubizo bya anhydride na diol yakoreshejwe muguhindura EA kugirango ihindure imiterere ya firime yakize, kandi ihinduka ryahinduwe binyuze muburebure bwurunigi rwa karubone ya diol.
Bitewe nimiterere yihariye, epoxy resin ikoreshwa cyane muruganda rutwikiriye kurusha ibindi byiciro byose bya binder. Mu gitabo cyabo gishya cyitwa "Epoxy Resins", abanditsi Dornbusch, Christ na Rasing basobanura ibyibanze bya chimie yitsinda rya epoxy kandi bagakoresha uburyo bwihariye kugirango basobanure imikoreshereze y’ibisigisigi bya epoxy na fenokisi mu mwenda w’inganda - harimo kurinda ruswa, gutwika hasi, gutwika ifu n’imbere.
Ibinini bya resin byagabanutse mugusimbuza igice E51 na binary glycidyl ether. Ugereranije na EA idahinduwe, ubwiza bwa resin yateguwe muri ubu bushakashatsi buragabanuka kuva kuri 29800 bugera kuri 13920 mPa s (25 ° C), kandi guhinduka kwa firime yakize kwiyongera kuva kuri 12 kugeza kuri mm 1. Ugereranije na EA yahinduwe mubucuruzi yahinduwe, ibikoresho fatizo bikoreshwa murubu bushakashatsi birahendutse kandi byoroshye kubona hamwe nubushyuhe bwa reaction iri munsi ya 130 ° C, ukoresheje uburyo bworoshye bwo guhuza, kandi nta mashanyarazi kama.
Iyi reserach yasohotse mu kinyamakuru cya Coatings Technology and Research, Umubumbe wa 21, mu Gushyingo 2023.
