Iterambere rya Waterborne UV ikiza resin iraza

UV ni ubwoko bwo gutwikira bushobora gukira vuba muri firime mumasegonda make munsi ya irrasi ya ultraviolet (UV).UV itwikiriye ihita izunguruka hanyuma igaterwa ku kibaho cyo mu bikoresho hakoreshejwe imashini n'ibikoresho.Munsi ya irrasiyo yumucyo ultraviolet, iteza imbere kubora kwabayitangije, ikabyara radicals yubuntu, igatera resin reaction, kandi igahita ikomera muri firime idafite ihindagurika.Kubwibyo, birakora neza, icyatsi nibidukikije.

Mubisanzwe muri hydrata, Amazi ya UV yo mumazi nayo akoreshwa neza mubiti, plastike, icapiro, imiti ya buri munsi nizindi nzego kubera ibidukikije byangiza ibidukikije ndetse nubucuti bwubaka.Ibikoresho bibisi bigira uruhare runini.Guhora udushya twimikorere, ibiranga nibisubizo byokoresha amazi yo mumazi biteza imbere inzira ya hydrata.

1 epoxy acrylate / polyurethane acrylate sisitemu

Photosensitive oligomer nigice cyingenzi cya UV yakize resin, igena imiterere yibanze ya resin yakize.Ubwoko bwose bwa matrix resin ifite ibyiza byayo bidasubirwaho, ariko byanze bikunze bizagira inenge.Kurugero, epoxy resin ishingiye kuri firime ikiza ifite ubukana bwinshi, gufatana neza, kurabagirana kwinshi hamwe no kurwanya imiti myiza, ariko ifite ibibi byo guhinduka nabi.Urundi rugero ni uko polyurethane ishingiye kuri resin ifite ibintu byiza cyane nko kwambara no kurwanya ibishushanyo, ariko guhangana nikirere ntibihagije.Abashakashatsi bakoresha uburyo bwo kuvanga cyangwa kuvanga kugirango bahuze byombi, kugirango basubize ibura rya resin imwe kandi batezimbere sisitemu ifite ibintu byombi biranga ibyiza.

Sisitemu ya dendritic cyangwa hyperbranched sisitemu

Amazi ya UV yakira dendrimers cyangwa oligomers ya hyperbranched ni ubwoko bushya bwa polymers ifite imiterere ya sereferi cyangwa dendritic kandi ntaho ihuriye numunyururu wa molekile.Byongeye kandi, amashami menshi ya polymer yubatswe arimo umubare munini wibikorwa byanyuma.Aya matsinda arangiza akora yahinduwe kugirango ahindure imiterere ya polymer hanyuma ayashyire mubikorwa byihariye.Ugereranije na polymer yumurongo ufite uburemere buke bwa molekuline, oligomers ya hyperbranched ifite ibintu byiza cyane nko gushonga gake, ubukonje buke, gushonga byoroshye no gukora cyane.Nibikoresho byiza byumucyo wo mumazi ukiza matrix.Amazi ashingiye kuri hyperbranched polyester agizwe na polyhydroxy ikora ya aliphatic polyester nkuko intandaro ishobora kugabanya amazi ya dilution kandi ikagaragaza ingaruka nziza yo kugabanya ubukonje kubera amazi meza kandi afite ubukonje buke.

3 epoxy ya soya yamavuta acrylate

Amavuta ya soya ya Epoxy afite ibyiza byo kugiciro gito, kurengera ibidukikije, urunigi rurerure hamwe nubucucike buringaniye.Irashobora kunoza cyane guhinduka no gufatira hamwe.Mu myaka yashize, yahindutse ahantu h’ubushakashatsi mu bijyanye no gutwikira mu gihugu no hanze yacyo.Ibyagezweho byagezweho muri epoxy soya ya peteroli ya acrylate hamwe na epoxy soya ya soya ya acrylate UV yubusa radical curing coatings mubushinwa.Isosiyete ya Cub muri Amerika yakoze umusaruro wubucuruzi, nka ebercy860.Uburyo bwa synthesis yuburyo bwa epoxy ya soya ya acrylate muri rusange ni uburyo bwo guhindura igice cya ester, aribwo buryo bwo kumenya amavuta ya soya ya epoxy hamwe na acide acrylic.
