Dab tsi yog tus cwj mem siv los tshuaj ntsuam iav luam ntawv?
Kev tshuaj ntsuam luam ntawv yog cov txheej txheem nrov siv los hloov cov duab mus rau ntau hom chaw, suav nrog iav. Nws muaj ntau txoj hauv kev los tsim cov khoom siv hauv iav, qhov rais, iav tsheb, thiab txawm tias iav vaj tse. Txawm li cas los xij, thaum nws los txog rau kev luam ntawv ntawm iav, xaiv tus cwj mem zoo yog qhov tseem ceeb kom ntseeg tau tias lub neej ntev, xim zoo nkauj, thiab adhesion. Hauv tsab xov xwm no, peb yuav tshawb txog ntau hom inks siv rau kev tshuaj ntsuam luam ntawv ntawm iav.
Taw qhia rau Screen Printing ntawm iav
Kev tshuaj ntsuam luam ntawv ntawm iav cuam tshuam cov txheej txheem ntawm kev yuam tus number case los ntawm lub vijtsam zoo mesh mus rau iav substrate. Lub vijtsam ua raws li stencil, tso cai rau tus number case dhau los ntawm cov chaw tshwj xeeb, tsim cov qauv xav tau lossis duab. Cov txheej txheem no, tseem hu ua silkscreen luam ntawv lossis serigraphy, tuaj yeem tsim cov qauv sib txawv nrog cov xim zoo nkauj.
Kev tshuaj ntsuam luam ntawv feem ntau muaj cov kauj ruam hauv qab no:
1. Kev Npaj Tsim: Cov duab kos duab lossis cov qauv tsim yog tsim thiab npaj rau kev tshuaj ntsuam luam ntawv siv software tshwj xeeb.
2. Kev Npaj Cov Tshuaj Ntsuam: Lub vijtsam zoo mesh yog coated nrog lub teeb-sensitive emulsion, qhuav, thiab tom qab ntawd raug teeb pom kev zoo nrog cov qauv tsim pob tshab lossis cov duab zoo nkauj.
3. Ntxuav thiab ziab: Tom qab lub vijtsam raug, nws raug ntxuav nrog dej kom tshem tawm cov emulsion tsis raug. Thaum qhuav, lub vijtsam yog npaj rau daim ntawv thov number case.
4. Ink Preparation: Tus number case yog tov thiab npaj raws li qhov xav tau xim thiab sib xws.
5. Kev luam ntawv: Tus number case tau muab tso rau ntawm ib qho kawg ntawm lub vijtsam, thiab rub lub squeegee hla, yuam tus number case los ntawm qhov qhib qhov screen thiab mus rau lub khob.
6. Kev Kho: Lub khob luam ntawv yog kho los yog qhuav kom ntseeg tau tias tus number case adheres zoo thiab ua mus tas li.
Hom Ink rau Screen Printing ntawm iav
Ntau hom number case tuaj yeem siv rau kev tshuaj ntsuam luam ntawv ntawm iav, txhua qhov muab cov yam ntxwv tshwj xeeb thiab tsim nyog rau cov ntawv thov tshwj xeeb. Qee qhov feem ntau siv inks rau iav npo luam ntawv yog:
1. Ceramic Inks: Ceramic inks yog tsim tshwj xeeb nrog cov iav thiab ceramic pigments tshem tawm hauv cov iav fusing tsawg. Cov inks no tuaj yeem tiv taus qhov kub thiab txias thiab yog qhov zoo rau cov ntawv thov uas cov iav luam tawm yuav raug rho tawm haujlwm hauv qhov cub. Ceramic inks muab cov adhesion zoo thiab ua haujlwm ntev, ua rau lawv haum rau cov iav vaj tsev, cov iav zoo nkauj, thiab iav kos duab.
2. UV-Curable Inks: UV-curable inks tau dhau los ua neeg nyiam rau kev tshuaj ntsuam luam ntawv ntawm iav vim lawv cov khoom kho sai. Cov inks no muaj photoinitiators uas hnov mob thiab tawv thaum raug UV teeb. UV-curable inks muab cov xim zoo nkauj, siab gloss, thiab khawb tsis kam. Lawv kuj tshem tawm qhov xav tau kev tua hluav taws vim lawv kho tam sim ntawd. Txawm li cas los xij, cov inks no yuav tsis haum rau cov iav sab nrauv uas tuaj yeem raug tshav ntuj ntev, vim lawv yuav ploj mus ntev.
3. Epoxy Inks: Epoxy inks yog ob-teev inks uas yuav tsum tau sib tov cov resin thiab hardener ua ntej thov. Lawv muaj qhov tshwj xeeb durability, tshuaj tiv thaiv, thiab feem ntau yog siv rau daim ntawv lo lossis kos rau ntawm cov iav nto. Epoxy inks tuaj yeem muab cov glossy lossis matte tiav thiab ua raws li cov iav substrates, ua rau lawv haum rau iav tsheb, hluav taws xob, thiab cov ntawv thov kev lag luam.
4. Solvent-based Inks: Solvent-based inks muaj cov pigments yaj los yog tshem tawm hauv cov kuab tshuaj organic. Cov inks no muaj qhov adhesion zoo rau iav thiab yooj yim ua haujlwm nrog. Lawv tuaj yeem muab ntau yam tiav, suav nrog matte, glossy, lossis pob tshab. Txawm li cas los xij, lawv tuaj yeem muaj cov ntxhiab tsw zoo, lub sijhawm ziab ntev dua, thiab xav tau qhov cua kom zoo vim siv cov kuab tshuaj. Cov kuab tshuaj raws li cov kuab tshuaj feem ntau yog siv rau cov iav, cov khoom lag luam, thiab cov khoom siv.
Kev txiav txim siab xaiv tus cwj mem zoo
Kev xaiv tus cwj mem zoo rau kev tshuaj ntsuam luam ntawv ntawm iav yuav tsum xav txog ntau yam, suav nrog cov ntawv thov, kev xav tau ntev, thiab cov yam ntxwv uas xav tau. Nov yog qee qhov kev xav kom nco ntsoov:
1. Daim Ntawv Thov: Txiav txim siab daim ntawv thov ntawm cov iav luam ntawv, seb nws yog cov iav zoo nkauj, iav kos duab, iav vaj tsev, lossis iav tsheb. Qhov no yuav pab txo qis cov cwj pwm tsim nyog.
2. Durability: Xav txog qhov yuav tsum tau ua kom ntev ntawm cov iav luam ntawv. Nws puas yuav raug tshav kub, tshuaj lom neeg, lossis ib puag ncig abrasive? Ceramic inks thiab epoxy inks paub txog lawv cov kav ntev thiab ua haujlwm rau ntau yam mob.
3. Cov txheej txheem kho: Ntsuas cov txheej txheem kho uas yuav tsum tau ua rau tus cwj mem xaiv. Qee cov inks yuav xav tau kev tua hluav taws, UV kho cov cuab yeej, lossis lub sijhawm kho tshwj xeeb. Xyuas kom meej tias muaj cov peev txheej thiab cov khoom siv tuaj yeem ua raws li tus cwj mem xaiv.
4. Xim Opacity: Nyob ntawm cov duab xav tau lossis tsim, xav txog qhov opacity ntawm tus number case. Ceramic inks, piv txwv li, tuaj yeem muab cov xim zoo nkauj thiab opaque piv rau lwm hom number case.
5. Ib puag ncig Factors: Yog tias cov iav luam tawm yuav raug rau sab nraum zoov ib puag ncig lossis lub hnub ci zoo ib yam, xav txog UV-resistant inks lossis cov txheej tiv thaiv ntxiv kom tsis txhob muaj xim fading.
6. Kev ua raws cai: Hauv qee daim ntawv thov, xws li khoom noj lossis dej haus khob iav, nws yog ib qho tseem ceeb kom ntseeg tau tias tus number case xaiv tau ua raws li cov cai, xws li FDA lossis EN.
