Mvura yakavharwa neUV machira anonyanya kusanganisira Waterborne UV resins, photoinitiators, additives uye coloring coatings.Pakati pezvinhu zvese, iyo Waterborne UV resin ine yakanyanya kukanganisa pakuita kweWaterborne UV coating.Kuita kweWaterborne UV resin kunokanganisa kusimba, kusimba kwekuora uye kurapa kunzwa kwefirimu rakaporeswa pamusoro peiyo coating [1].Mvura-based resin inobatwawo ne photoinitiator.Pasi pesimba rephotoinitiator, mvura-based resin inogona kurapwa pasi pechiedza.Naizvozvo, photoinitiator zvakare chikamu chakakosha cheWaterborne UV coatings.Iyo yeramangwana kusimudzira kudiwa kwephotoinitiator ndeye polymerizable uye macromolecular.
Zvakanakira zveWaterborne UV majasi: iyo viscosity yejasi inogona kugadziridzwa pasina diluting monomers, kubvisa muchetura uye kutsamwiswa kwechinyakare majasi.Rheological additives inogona kunyatsowedzerwa kudzikisa viscosity yeiyo coating system, iyo yakanakira nzira yekupfeka.Kana iyo yekupfekedza ichigadzirwa nepurasitiki uye zvimwe zvinhu, mvura inogona kushandiswa seyakanyungudika kuvandudza kunamatira pakati pekupfekedza uye kupfeka.Inonatsiridza hupfu-hupupuriro uye kukwenya humbowo kugona kwejasi isati yapora, inonatsiridza kupera kwejasi, uye firimu rakaporeswa rakanyanya-mutete.Coating midziyo iri nyore kuchenesa.Mvura yakavharwa neUVB yakajairwa ine yakanaka kunonoka murazvo.Sezvo pasina yakaderera molecular inoshanda diluent inoshandiswa, kuchinjika uye kuoma kunogona kutariswa.
Mvura inotakura UV resin coatings inogona kuchinjika uye kurapwa nekukurumidza pasi pechiito chephotoinitiator uye ultraviolet mwenje.Mukana wakakura weresin inotakurwa nemvura inodzoreka viscosity, kuchena, kuchengetedza kwezvakatipoteredza, kuchengetedza simba uye kugona kwakanyanya, uye chimiro chemakemikari cheprepolymer chinogona kugadzirwa zvinoenderana nezvinodiwa chaizvo.Zvisinei, kuchine zvimwe zvinokanganisa muhurongwa uhu, zvakadai sekugadzikana kwenguva refu kwekuputira mvura yekuparadzira system inoda kuvandudzwa, uye kunwa kwemvura kwefirimu yakarapwa kunoda kuvandudzwa.Dzimwe nyanzvi dzakaratidza kuti mune ramangwana, tekinoroji yekurapa mwenje yemvura ichavandudza mune zvinotevera.
(1) Kugadzirira kwemaoligomers matsva: kusanganisira yakaderera viscosity, yakakwirira basa, yakakwirira yakasimba yezvinyorwa, multifunctional uye hyperbranched.
(2) Gadzira matsva anoshanda diluents: anosanganisira matsva acrylate anoshanda diluents, ane yakanyanya kutendeuka, yakakwirira reactivity uye yakaderera vhoriyamu shrinkage.
(3) Tsvagiridzo pamasisitimu matsva ekurapa: kuti ukunde hurema hwekusakwana kwekurapa dzimwe nguva kunokonzerwa nekushomeka kweUV kupinda, maviri maviri ekurapa masisitimu anogamuchirwa, akadai semahara radical mwenje kurapa / cationic mwenje kurapa, mahara radical mwenje kurapa, kupisa kupisa, mahara radical mwenje kurapa / anaerobic kurapa, mahara radical mwenje kurapa / kunyorova kurapa, mahara radical mwenje kurapa / redox kurapa, kuitira kuti ipe kutamba kwakazara kumubatanidzwa pakati pezviviri izvi, Kurudzira kuenderera mberi kwenzvimbo yekushandisa yemvura inorapa zvinhu. .
