Mvura yakavharwa neUV machira anogona kukurumidza kuyambuka-yakabatana uye kuporeswa pasi pechiito chephotoinitiators uye ultraviolet mwenje. Kubatsira kukuru kwemvura-based resin ndeyekuti viscosity inodzoreka, yakachena, inoshamwaridzana nenharaunda, inochengetedza simba uye inoshanda, uye chimiro chemakemikari yeprepolymer inogona kugadzirwa zvinoenderana nezvinodiwa chaizvo. Zvisinei, iyi gadziriro ichine zvikanganiso, zvakadai sekugadzikana kwenguva refu kwekuputira mvura yekuparadzira system inoda kuvandudzwa, uye kunwa kwemvura kwefirimu yakarapwa kunoda kuvandudzwa. Dzimwe nyanzvi dzakaratidza kuti tekinoroji yeramangwana-yakavakirwa mvura yekurapa inovandudza mune zvinotevera zvinhu.
(1) Kugadzirira kwemaoligomers matsva: kusanganisira yakaderera viscosity, yakakwirira basa, yakakwirira yakasimba yezvinyorwa, multifunctionality uye hyperbranching.
(2) Gadzira mitsva inogadzirisa diluents: inosanganisira itsva acrylate reactive diluents, ine yakanyanya kutendeuka rate, yakakwirira reactivity uye yakaderera vhoriyamu shrinkage.
(3) Tsvagiridzo yemasisitimu matsva ekurapa: Kuti ukunde hurema hwekurapa kusina kukwana dzimwe nguva kunokonzerwa nekupinzwa kwechiedza cheUV, maitiro maviri ekurapa anoshandiswa, akadai semahara radical photocuring/cationic photocuring, free radical photocuring, thermal kurapa, free radical. photocuring, uye yemahara radical photocuring. Zvichienderana nekutora mifananidzo / anaerobic kurapwa, mahara radical kupora / kunyorova kurapa, mahara radical photocuring / redox kurapa, nezvimwewo, iyo synergistic mhedzisiro yezviviri izvi inogona kuitiswa zvizere, izvo zvinosimudzira kuenderera mberi kwenzvimbo yekushandisa yemvura inorapika zvinhu.
