Chii chinonzi UV-kuporesa resin?
Ichi chinhu chino " polymerizes uye kurapa munguva pfupi nesimba re ultraviolet rays (UV) inoburitswa kubva kune ultraviolet irradiation mudziyo".
Yakanakisa zvimiro zveUV-inorapa resin
- Kukurumidza kuporesa kumhanya uye kupfupisa nguva yekushanda
- Sezvo isingarape kunze kwekunge yatungidzwa neUV, pane zvishoma zvirambidzo pamaitiro ekunyorera
- Chimwe-chikamu nonsolvent ine basa rakanaka
- Inoona zvakasiyana siyana zvakaporeswa zvigadzirwa
Kurapa nzira
UV-inorapa resins yakakamurwa kuita acrylic resins uye epoxy resins.
Ose ari maviri anorapwa ne UV irradiation, asi maitiro ekuita akasiyana.
Acrylic resin: radical polymerization
Epoxy resin: cationic polymerization
Zvimiro nekuda kwekusiyana kwemhando dzephotopolymerization
UV irradiation zvishandiso
Kuchenjerera kushandiswa
Kusimbisa mamiriro ekurapa
Kusimba, nguva, mwenje wakashandiswa (rambi rudzi uye wavelength)
Nzvimbo yebasa
Shading zviyero, kushandiswa kwemidziyo yekudzivirira, kuiswa kwemhepo yemukati
Irradiation mudziyo manejimendi
Hupenyu hwemwenje, mafirita, mavara egirazi
Kuchengeta nzira
Tarisa nzira yekuchengetedza (humidity) yechigadzirwa chimwe nechimwe
Notes:
Isa iyo yakanyanya kunaka irradiation mamiriro zvinoenderana nechinangwa.
Nekuongorora resin pasi pemamiriro akafanana ekurapa senge mukugadzirwa kwakawanda, matambudziko ekutanga anoderedzwa.
Tarisa nguva nenguva kuti uone kana mamiriro ekuiswa kwe irradiation akachengetwa.
