Nhasi, mugadziri weese-pass screen printing glass screen printing machine achakutsanangurira nzira dzakasiyana dzekugadzirwa kwescreen printing:
 |
Mukudhindwa kwechidzitiro cheotomatiki chidzitiro chekudhinda muchina, zvinoenderana neyakasiyana mbichana, nzira yacho inogona kukamurwa kuita yemvura mhando yakananga nzira photosensitive offset plate kugadzira, pre-sensitized yakananga nzira firimu (yemvura firimu) kugadzira ndiro, isina kunanga nzira firimu ndiro. kugadzira, nezvimwewo.
1. Mvura yakananga nzira photoresist
Kubatsira kwe photosensitive adhesive ndeyekuti maitiro acho ari nyore, ane mari uye anoshanda.Hunhu hwayo kukurumidza kuratidzwa kumhanyisa, yakasimba screen plate uye nyore kubvisa firimu, yakanakisa solvent kuramba, uye maitiro ayo ekugadzira ndeaya:
Magadzirirwo ezvidziviriro nekusarudza sikirini → kunama → kunama → kuomesa → kuratidzwa → kuvandudza → kumira
Nzvimbo yaro yekushanda ndeye tembiricha 15 ~ 20 ℃, tembiricha yakaenzana 50 ~ 65%, kushanda mukamuri rerima pasi pechiedza cheyero.
2. Mvura firimu mutemo ndiro kugadzira nzira
Kuyerera kwemaitiro: pre-screen kurapwa uye kusarudzwa skrini → kunamatira firimu → kuomesa → kuratidzwa → kusimudzira → kumira
3. Capillary photosensitive film
Pre-kurapa (kusanganisira roughening uye degreasing wewaya mesh) - kubatanidza firimu - kuomesa firimu - kuratidzwa
4. Photosensitive paste yakananga ndiro kugadzira nzira
Nzira: Pfekedza imwe gobvu ye photosensitive paste (kazhinji diazonium munyu photosensitive paste) pachiratidziro chakatambanudzwa, woomesa mushure mekuputira, wobva waibatanidza neplate-yekugadzira negative woiisa mumushini wekudhinda kuti uonekwe, wobva wagadzira uye sukurudza., Mushure mekuoma, inova skrini yekudhinda skrini.
Kuyerera kwemaitiro: kugadzirira kwephotosensitive paste, yakatambanudzwa mambure - degreasing - kuomesa - kufukidza firimu - kuomesa - kuratidzwa - kuvandudza - kuomesa - kudzokorora - post exposure - kuvhara mambure.
5. Photosensitive film direct plate making method
Method: Iyo photosensitive firimu, inowanzozivikanwa semvura firimu, inogadzirwa neyakajeka yepurasitiki firimu ine ukobvu hwe0.1mm seyemufirimu base, uye dhizaini yephotosensitive emulsion ine humwe ukobvu yakaputirwa kune rimwe divi.Isa pafirimu, iyo firimu inoshambadzirwa kuchiratidziro necapillary chiito, uye mushure mekuoma, firimu repurasitiki rinobvarurwa kuti rionekwe uye kusimudzira, uye pakupedzisira maitiro anodiwa anowanikwa.
Tekinoroji maitiro: yakatambanudzwa mambure - degreasing - kunyorova - kupfura - kuomesa - kusimbisa - kuratidzwa - kukura - kuomesa - kudzokorora - kuvhara skrini
Izvo zviri pamusoro ndedzimwe ruzivo rudiki nezve nzira dzakasiyana dzekugadzira dzekudhinda skrini inoudzwa nemugadziri wemuchina wekudhinda skrini.
