Taw qhia:

Cov tshuab luam ntawv ua lub luag haujlwm tseem ceeb hauv peb lub ntiaj teb niaj hnub no, pab txhawb kev tsim cov ntaub ntawv suav tsis txheeb uas peb tuaj nyob txhua hnub. Hauv qab qhov xwm txheej, cov tshuab luam ntawv qib siab no muaj ntau yam tseem ceeb uas ua haujlwm ua ke tsis sib haum los tsim cov ntawv luam tawm zoo. Ntawm cov khoom no, lub tshuab luam ntawv cov ntxaij vab tshaus tuav qhov tseem ceeb uas tsis tuaj yeem lees paub. Hauv tsab xov xwm no, peb yuav delve rau hauv cov ntsiab lus tseem ceeb ntawm cov tshuab luam ntawv siab heev, ci ntsa iab ntawm qhov tseem ceeb thiab kev ua haujlwm ntawm cov tshuab luam ntawv cov ntxaij vab tshaus.

1. Nkag siab txog cov tshuab luam ntawv cov ntxaij vab tshaus

Lub tshuab luam ntawv cov ntxaij vab tshaus, tseem hu ua mesh cov ntxaij vab tshaus lossis cov ntxaij vab tshaus, yog ib feem tseem ceeb ntawm cov txheej txheem luam ntawv. Cov ntxaij vab tshaus no yog ua los ntawm cov khoom siv mesh, feem ntau yog tsim los ntawm cov ntaub ntawv xws li polyester, nylon, lossis stainless hlau. Lub mesh yog stretched thiab txuas mus rau ib tug ruaj khov thav duab, tsim ib tug taut nto uas ua hauj lwm raws li lub hauv paus rau cov txheej txheem luam ntawv. Cov ntxaij vab tshaus mesh tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab mesh suav, tso cai rau ntau yam thiab kho raws li cov kev cai luam ntawv tshwj xeeb.

Lub tshuab luam ntawv cov ntxaij vab tshaus ua raws li cov kav dej rau kev xa cov qauv tsim mus rau ntau qhov chaw. Lawv tuav lub luag haujlwm tseem ceeb ntawm kev tswj cov kua dej ntws thiab ua kom cov duab zoo dua qub. Cov ntxaij vab tshaus luam ntawv muaj cov me me apertures, los yog mesh qhib, uas tso cai rau tus number case hla thaum lub sij hawm luam ntawv. Kev suav cov mesh txiav txim seb tus naj npawb ntawm qhov qhib ib kab inch, cuam tshuam rau theem ntawm kev nthuav dav thiab kev daws teeb meem uas tuaj yeem ua tiav.

2. Mesh xaiv thiab Customization

Kev xaiv ntawm qhov tsim nyog mesh rau lub tshuab luam ntawv siab heev yog qhov tseem ceeb heev kom ua tiav qhov kev luam ntawv zoo. Muaj ntau yam yuav tsum tau xav txog thaum xaiv qhov zoo tagnrho mesh, nrog rau hom number case siv, cov khoom siv substrate, thiab cov duab daws teeb meem.

Cov mesh suav yog hais txog tus naj npawb ntawm cov mesh qhib rau ib kab inch. Ntau dua mesh suav, xws li 280 lossis 350, yog qhov nyiam rau cov qauv tsim thiab cov ncauj lus kom ntxaws, qhov qis mesh suav, zoo li 86 lossis 110, yog qhov tsim nyog rau cov ntawv luam tawm thiab opaque. Qhov kev hloov kho no tso cai rau cov tshuab luam ntawv cov ntxaij vab tshaus kom haum rau ntau yam kev xav tau luam ntawv.

Cov khoom siv mesh kuj tseem ua lub luag haujlwm tseem ceeb hauv cov txheej txheem luam ntawv. Polyester mesh cov ntxaij vab tshaus yog nrov vim lawv pheej yig, durability, thiab tsis kam mus rau tshuaj. Nylon mesh cov ntxaij vab tshaus, ntawm qhov tod tes, muab cov elasticity zoo heev thiab zoo tagnrho rau cov ntawv thov kom ncab thiab nro. Stainless hlau mesh cov ntxaij vab tshaus yog ruaj thiab corrosion-resistant, ua rau lawv haum rau high-volume thiab industrial printing.

3. Lub luag hauj lwm ntawm Kev Nyuaj Siab thiab Squeegee Siab

Ua kom tau raws li qhov nro thoob plaws hauv lub tshuab luam ntawv yog qhov tseem ceeb los xyuas kom pom cov txiaj ntsig luam ntawv zoo. Lub nro nyob rau hauv qhov screen mesh txiav txim siab tswj thiab uniformity ntawm number case deposition. Tsis txaus nro tuaj yeem ua rau tus number case to los yog cov ntawv luam tawm tsis sib xws, thaum qhov nro ntau dhau tuaj yeem ua rau mesh puas ntxov ntxov thiab cuam tshuam rau cov duab sau npe.

Txhawm rau ua tiav thiab tswj cov kev xav tau nruj, cov tshuab luam ntawv qib siab siv cov khoom siv tensioning uas ncab cov ntxaij vab tshaus sib npaug. Cov cuab yeej no tso cai rau kev hloov kho kom raug, kom ntseeg tau tias qhov nro sib npaug sib npaug ntawm tag nrho lub vijtsam. Kev tswj xyuas qhov nro tsis tu ncua yog cov txheej txheem txuas ntxiv uas yuav tsum tau kuaj xyuas thiab hloov kho raws sijhawm.

Ua ke nrog nro, squeegee siab kuj cuam tshuam rau cov txheej txheem luam ntawv. Lub squeegee, roj hmab hniav mounted ntawm ib tug kov, yog siv los thov siab rau tus number case ntawm lub mesh screen, yuam nws los ntawm lub mesh qhib mus rau lub substrate. Qhov tsim nyog squeegee siab ua kom tus number case hloov tau zoo, tiv thaiv tus number case los ntshav los yog smudging. Kev txawj ntse ntawm squeegee siab yog qhov tseem ceeb heev kom ua tiav cov ntawv luam tawm zoo nkauj thiab raug.

4. Emulsion txheej thiab kev npaj duab

Ua ntej cov txheej txheem luam ntawv pib, lub mesh screen undergoes emulsion txheej thiab kev npaj duab. Emulsion, lub teeb-rhiab heev, yog siv rau lub mesh nto, tsim ib tug stencil uas yuav tso cai rau tus number case los ntawm tej qhov chaw thaum luam ntawv. Cov stencil no yog tsim los ntawm nthuav tawm cov coated mesh screen rau ultraviolet (UV) lub teeb los ntawm ib zaj duab xis zoo nrog tus tsim.

Kev npaj duab yuav npaj qhov xav tau tsim lossis kos duab rau kev luam ntawv. Nyob rau hauv cov ntaub ntawv ntawm kev tshuaj ntsuam luam ntawv, qhov no feem ntau entails converting tus tsim rau hauv high-zoo dub thiab dawb duab uas yuav ua tau raws li cov zaj duab xis zoo. Cov yeeb yaj kiab zoo yog tom qab ntawd muab tso rau sab saum toj ntawm lub vijtsam coated, thiab UV lub teeb raug rau hardens cov emulsion nyob rau hauv cov cheeb tsam sib xws rau cov qauv tsim.

Thaum UV raug ua tiav, lub vijtsam yog yaug nrog dej, tshem tawm cov emulsion uas tsis tau pom dua thiab tawm hauv qab ib qho stencil meej rau ntawm qhov chaw mesh. Lub vijtsam emulsion-coated tam sim no tau npaj rau daim ntawv thov number case thiab cov txheej txheem luam ntawv pib.

5. Kev tu thiab kav ntev

Txhawm rau kom lub neej ntev thiab kev ua haujlwm zoo ntawm cov tshuab luam ntawv cov ntxaij vab tshaus, kev saib xyuas kom zoo yog qhov tseem ceeb. Kev tu cov ntxaij vab tshaus tsis tu ncua tom qab txhua qhov kev luam tawm yuav pab tiv thaiv kom tsis txhob muaj cov kua roj vanish thiab cov khoom tsim uas tuaj yeem cuam tshuam rau cov luam tawm tom ntej. Kev ntxuav cov kev daws teeb meem tshwj xeeb tsim rau kev tshuaj ntsuam luam ntawv tau pom zoo kom tsis txhob muaj kev puas tsuaj rau cov mesh lossis emulsion.

Ntxiv nrog rau kev tu txhua hnub, kev tshuaj xyuas ib ntus thiab kho yog tsim nyog los daws cov cim qhia ntawm kev hnav thiab tsim kua muag. Cov ntxaij vab tshaus uas puas los yog torn yuav tsum tau hloov tam sim ntawd los yog kho kom tsis txhob muaj kev cuam tshuam cov luam ntawv zoo. Kev khaws cia kom zoo, xws li khaws cov ntxaij vab tshaus tiaj tus thiab tiv thaiv plua plav thiab av noo, ua rau lawv lub neej ntev dua.
