Gelation inoreva kukora kana kukaka kweUV resin kana kukoira patembiricha yakatarwa nenguva.
Zvikonzero zvikuru zvegelatinization yeUV resin kana kupfeka ndeiyi inotevera:
1. Kunze kwehupenyu hwesherufu, hupenyu hwesherufu yeUV resin pasi pemamiriro akanaka ekuchengetedza haifaniri kudarika mwedzi mitanhatu.Asi Z yakanaka inogona kushandiswa kumusoro mumwedzi mitatu.
2. UV resin inofanira kuchengetwa mumapuranga epurasitiki kana simbi yesimbi yakaputirwa nepurasitiki.Metal ions inoderedza iyo activation simba rezvisungo zvakapetwa muUV resin uye kutanga polymerization, zvichikonzera resin gelation.Naizvozvo, kana iyo yepurasitiki yekuisa mudhiramu mupurasitiki yakakuvadzwa, iyo isina simbi simbi inokonzeresa resin gelation.
3. Tembiricha yakadzikira yekuchengetera (pazasi 0 ℃) inokonzeresa iyo polymerization inhibitor mufirimu repende, zvichikonzera resin self polymerization uye resin gelation.
4. UV resin inofanira kuchengetedzwa zvakasimba kubva kune zuva rakananga panguva yekuchengetedza.Kana zvisina kudaro, zviri nyore kukonzera resin gelation.
5. Kana bhodhoro rakanyanyisa, hapana okisijeni yakakwana yekudzivirira polymerization, iyo inokonzera resin gelation.
Maitiro ekudzivirira gelation:
1. Iyo viscosity ye resin isina diluting monomer yakakwirira kwazvo.Vamwe vashandisi vachakanganisa kufunga kuti resin yakave gelatinized.Muchokwadi, zviri nyore kuona kana resin iri gelatinized mushure mekupisa.Iyo resin isina gelatinization ichave yakanaka fluidity mushure mekupisa.
2. Kana zviri zvekushandiswa kweUV resin, nzira dzekuona uye zviratidzo zveUV coating film zvakafanana neaya emamwe mapeji, ayo anosiyana nekushandiswa kwakananga.Pachave nematambudziko akasiyana mukushandiswa kweUV coatings.Chete gelatinization panguva yekuchengetedza inowirirana zvakanyanya neUV resin pachayo, uye mamwe matambudziko anogona kugadziriswa nekugadzirisa UV coating formula.Sezvo uvpaint inoumbwa nezvinhu zvakasiyana-siyana, inokanganisawo nechiedza chechiedza chekuvhenekera kure uye nguva yekuvhenekera, uye kuita kwayo firimu ndiko mhedzisiro yekuita kwakadzama kwezvinhu zvakasiyana.Kune imwechete formula, pakarepo shandura iyo yakafanana resin.Nekuda kwekusiyana kweresin kubva kune vakasiyana vagadziri, kuita kwefirimu kuchashandurwa, uye fomula inoda kugadziridzwa.Zvisinei, chero bedzi resin isiri gelatinized kana gelatinized mupende yakagadzirwa, kushanda kwefirimu kunogona kugadziriswa kuburikidza nekugadzirisa.
3. Pane zvikonzero zvakawanda zvegelatinization yepende yeUV, iyo isingabatanidzi chete neresin.Kutanga, tinofanira kutarisa kuti inokonzerwa nekuchengetedza kusina kunaka.Nekuda kwekuwedzera kwephotosensitizer muUV coating, mamiriro ayo ekuchengetedza akanyanya kuomarara kupfuura ayo eUV resin.Zvakakosha kuichengeta murima kuti isaone chiedza.Chechipiri, iyo photosensitizer yakasarudzwa ndeyehurombo husina kunaka, uye kunyangwe ikachengetwa murima, inozoora zvishoma nezvishoma uye kukonzera gelation yeakapora coating.
4. Hunhu hwemonomeri zvakare chinhu chakakosha chinokanganisa kugadzikana kwekuchengetedza.
