Niaj hnub no, cov chaw tsim tshuaj paus ntawm all-pass screen printing iav screen tshuab luam ntawv yuav piav qhia rau koj txog ntau txoj kev sib txawv ntawm kev tshuaj ntsuam luam ntawv:
 |
Hauv kev tshuaj ntsuam luam ntawv ntawm lub tshuab luam ntawv tsis siv neeg lub tshuab luam ntawv, raws li cov ntaub ntawv sib txawv, cov txheej txheem tuaj yeem muab faib ua cov kua hom ncaj qha photosensitive offset phaj ua, pre-sensitized direct method film (dej zaj duab xis) phaj ua, indirect method film phaj. kev, etc..
1. Liquid direct method photoresist
Qhov zoo ntawm photosensitive nplaum yog cov txheej txheem yooj yim, kev lag luam thiab siv tau.Nws cov yam ntxwv yog ceev ceev ceev, ruaj lub phaj phaj thiab yooj yim tshem tawm zaj duab xis, hnyav hnyav kuj, thiab nws cov txheej txheem ntau lawm yog:
Screen pretreatment thiab xaiv qhov screen → gluing → gluing → ziab → raug → tsim → standby
Nws qhov chaw ua haujlwm yog kub 15 ~ 20 ℃, txheeb ze kub 50 ~ 65%, kev ua haujlwm hauv chav tsaus ntuj hauv qab lub teeb daj.
2. Dej zaj duab xis txoj cai phaj ua txoj kev
Txheej txheem khiav: pre-screen kho thiab kev tshuaj ntsuam xaiv → zaj duab xis sticking → ziab → raug → kev loj hlob → standby
3. Capillary photosensitive zaj duab xis
Kev kho ua ntej (xws li roughening thiab degreasing ntawm hlau mesh) - txuas zaj duab xis - zaj duab xis kom qhuav - raug
4. Photosensitive paste direct phaj ua txoj kev
Txoj kev: Coated ib co thickness ntawm photosensitive muab tshuaj txhuam (feem ntau diazonium ntsev photosensitive muab tshuaj txhuam) ntawm lub stretched screen, qhuav nws tom qab txheej, thiab ces muab nws nrog ib tug phaj-ua tsis zoo thiab muab tso rau hauv lub tshuab luam ntawv kom raug, thiab ces tsim thiab yaug., Tom qab ziab, nws dhau los ua lub vijtsam luam ntawv.
Cov txheej txheem ntws: kev npaj cov tshuaj pleev ib ce, ncab net - degreasing - ziab - txheej zaj duab xis - ziab - raug - tsim - ziab - kho - tom qab raug - sealing net
5. Photosensitive zaj duab xis ncaj phaj ua txoj kev
Txoj kev: Cov yeeb yaj kiab photosensitive, feem ntau hu ua cov yeeb yaj kiab dej, yog ua los ntawm cov yas pob tshab nrog lub thickness ntawm 0.1mm raws li lub hauv paus zaj duab xis, thiab ib txheej ntawm photosensitive emulsion nrog ib tug tej thickness yog coated ntawm ib sab.Muab tso rau hauv zaj duab xis, zaj duab xis yog adsorbed rau qhov screen los ntawm capillary kev txiav txim, thiab tom qab ziab, cov yas zaj duab xis yog rhais tawm rau raug thiab kev loj hlob, thiab thaum kawg qhov xav tau qauv yog tau.
Cov txheej txheem thev naus laus zis: stretched net - degreasing - moistening - filming - drying - reinforcement - exposure - developing - drying - revision - sealing screen
Cov saum toj no yog qee qhov kev paub me me txog kev tsim khoom sib txawv ntawm kev tshuaj ntsuam luam ntawv uas lub tshuab luam ntawv tshuab luam ntawv qhia rau koj..
