1. Hauv kev tsim cov qauv zoo nkauj, yog vim li cas kev siv cov npo daj dua lub vijtsam dawb tom ntej yuav nce?

Vim hais tias dawb screen refraction thiab reflection nyob rau hauv cov khoom luam tawm cov ntaub ntawv yog lub teeb dawb, lub spectrum tau approximated rau cov duab photosensitive, thaum lub vijtsam qis, lub reflection ntawm lub spectrum yog nyob ze rau cov kev ruaj ntseg ntawm cov khoom siv lub teeb-sensitive, lub luag hauj lwm ntawm cov khoom siv rau lub teeb, Yog li nrog nws cov zus npo, lub sij hawm raug tus kab mob yuav tsum tau nce (1/2 rau 1/3 los yog li ntawd), kom tsis txhob muaj kev sib tw thiab txo cov ntaub ntawv thiab cov ntaub ntawv teeb pom kev nrawm.

2 multicolor overprinting ob peb daim ntawm npo Vim li cas cov kab (los ntawm, latitude) kev txiav txim, nro thiab lwm yam yuav tsum ua kom zoo ib yam?

Raws li hauv cov ntawv xov xwm, lub xov hluav taws xob thiab cov phom nyhuv yog muaj feem xyuam sib txawv, thaum muaj ntau yam ntxig khoom muaj feem xyuam los ntawm kev ua phom los yog cov khoom nyhav, feem ntau cov xim tshuav ntau dhau, koj tsis tuaj yeem poob qhov xim xim, Ntawm Lai khoom teeb (xim) thiab npliag xim thiab lwm yam teeb meem. , Khaws cov vev xaib, txiav kev quab yuam, ncab lub sijhawm nruj, ua kom paub tseeb tias qhov chaw ua haujlwm dhau los yog muaj tseeb, tsis tsim kev lag luam.

3. Ntsuas hauv kev siv cov txheej txheem ntawm vim li cas qhov txuas, qhov txawv?

Lub ntsiab tseem ceeb rau qhov screen elongation yog tias qhov nro ntawm qhov screen tsis yog mus rau cov kev cai liam thiaj li hais tias nws yuav tsis tau lub siab ntawm lub squeegeeing.According rau cov khoom tseem ceeb, yog vim li cas rau qhov kev hloov tshuaj ntsuam yuav tsum tau them sai sai rau lub sij hawm zoo, uas yog, Tom qab tso tawm ntawm qhov kev quab yuam txheej txheem, kom tswj tau qhov ruaj ntseg ntawm lub vijtsam tsom xam. Feem ntau yuav tsum tau ncav duab tso rau ntau tshaj 24 teev los ua cov duab.

4. Tom qab kis tau ntawm cov duab ci ntsa iab, sib tshuam, tsim cov ntsiab lus thiab lub luag haujlwm?

Cov duab ntawm tus qauv los ntawm cov qauv hauv cov qauv hauv cov txheej txheem network yog hu ua tus ntoo khaub lig-txuas, yog li tsim cov lipid molecules los yog muab los ntawm cov kua hnyav tsis sib tov hauv cov qauv ntawm qhov tshwm sim, uas paub tias yog cov txhauv bridging. Cov khoom zoo nkauj zoo nkauj yog ua los ntawm cov duab ci nrog cov bridging zoo, uas tuaj yeem txhim kho txoj haujlwm hnyav ntawm lub npo thiab ua kom zoo dua cov qauv tshuaj. Cov ntsiab lus ntawm cov ntsiab lus yog hais txog qhov seem ntawm cov khoom pov thawj tom qab cov dej hauv photoresist tag nrho cov volatilized, raws li feem pua ntawm photoresist. Muaj teeb pom kev zoo siab Jiao, ib qho yooj yim dua, ua ntawm kev tshuaj ntsuam graphics crisp, tag nrho, nyob rau hauv kev tshuaj ntsuam tseeb kuj ua si hauv kev txhim kho.

5. Lub sij hawm thaij thaij thiab dab tsi?

Thaum lub sij hawm ntev npaum li cas thiab lub txheej txheem lo ntsiab muag, duab ntxig, duab thaij duab sib luag, kev tshwm sim npo, qhov kev hloov ntawm qhov ntsuas, qhov fais fab thiab kub hloov thiab lwm yam, feem ntau, rhiab heev, daim duab zoo, lub teeb ci tshiab yog qhov tshiab, qhov tsis zoo ntawm cov yeeb yaj kiab yog qhov loj, lub sij hawm raug tau ua kom tsawg.

6. Thaum lub sij hawm raug tus kabmob tsim nyog, qhov kev tshuaj ntsuam tom qab kev txhim kho ntawm lub teeb ci thiab qhov screen tsis ruaj khov rau qhov yog vim li cas?

Lub ntsiab yog vim li cas qhov screen pre-treatment tsis zoo, kev sib tsoo net degreasing tsis txaus. Polyester mesh yuav tsum tau muab tsoo nrog ib qho txhuam ntxoov ntxoo rau roughen saum npoo thiaj li yuav ua rau kom muaj qhov sib xyaw nrog cov khoom ntim khoom. Kev ntsuas ntawm qhov tshuaj ntsuam yuav tsum tau hais tias qhov kev tshuaj ntsuam yuav ua kom muaj roj hydrophilic thiab, tsis tas li ntawd, tsis ua kom qhuav tom qab daim ntawv thov cov duab pleev xim (zaj duab xis) yuav ua rau kev tso tawm ntawm cov khoom siv yees duab tom qab kev txhim kho.

7. Yuav ua li cas luam tawm cov thickness ntawm 0.05 ~ 0.1 hli tuab kab?

Feem ntau xav txog peb yam: a. Yuav tsum siv ntxig mesh, xws li 43T lossis 54T screen; b. Yuav tsum tau siv nrog kev ua kom zoo, cov ntsiab lus (Plus-8000) rhiab thiab cov plaub hau tuab xws li: hom phom mixed; c. Yuav tsum tau siv nrog ib lub xauv npo ntawm tus cwj pwm, yog li ntawd lub siab blot yam tsis muaj dej khov.

Siv phaj tshuab:

Ua ntej: mus rau qhov kev ntsuas raws li cov lus pom ntawm kev sib txeeb Jiao, scraping tsib cov khaubncaws sab nraud povtseg, txhua txheej yuav tsum tau qhuav ntawm 45 , thiab tom qab ntawd ntawv ci (paste capillaries 80), kom qhuav thiab ces tawm ntawm lub tsho ntawm pob tshab, ~ 45 rov qab rau ntau tshaj 30 feeb, thiab tom qab ntawd raug, kev txhim kho, ziab, sealing yuav ua tau.

Thib ob: Tus thawj capillary 80 affixed mus rau qhov screen printing nto, thiab tom qab ntawd ces muab ntim cov xim xaub nti kos ob zaug, tom 40 ~ 45 ntawm qhov ziab, ua kom tawm ntawm cov zaj yeeb yaj kiab. Tom qab ntawd rov qab tsib zaug ntawm cov nqaij ncej qab ci rau hauv cov yeeb yaj duab capillary, txhua lub sijhawm ntawm 40 ~ 45 rau ziab, thiab tom qab ntawd raug, kev txhim kho, ziab, sealing yuav ua tau.

Yuav tsum tau number case viscosity tswj ntawm li 300PaS, hauv lub tshuab luam ntawv lub tshuab luam tawm tuaj yeem luam tau tuab tuab 0.05 ~ 0.12 hli kab

8. Yuav ua li cas kho lub screen printing ink viscosity?

Ua ntej siv tus xaj xaj ntim rau hauv siab ces feem ntau ntseeg tau hais tias tus xaj xauv npo ntawm tus cwj mem ntawm 25 xees npauj npaim, tus number case ntawm tus xaj lo rau ntawm qhov nruam nrawm, yuav pom tau tias tsim nyog tuaj yeem. Yog tias tus xaum xoom qis thiab nqis rau ntawm tus xaws xaws, nws qhia tau tias qhov siab tshaj qhov siab thiab qhov yuav tsum tau kho kom haum.

9. npo luam tawm ntawm tus ntawv nyeem ua zaj dab tsi yog qhov point?

Yuav tsum tau muab los ntawm lub khw tsim hom xim daim card, qhov zoo tshaj plaws hauv cov khoom siv ncaj qha uas tsis muaj xa tawm. Cov qib theem yuav tsum maj mam nqes ntawm qhov pib ntiav, yog li ntawd maj mam nyob ze rau ntawm daim npav xim. Thaum faib xim txawv, nws yog qhov yuav tsum tau xav txog tus cwj pwm substrate hom thiab tom qab xim, qhov txawv ntawm cov zauv kua thiab ntawm tus cwj pwm ntub dej, thiab cawv ntawm cov tawv nqaij ntawm cov tawv nqaij. Kom sai li sai tau, cov xim siv cov xim siv tsawg tsawg, cov thawj xim yog kho kom deb li deb tau, Ntshiab, tsis txho.

10 UV number case screen printing xim yuav ua li cas?

UV number case yog cwj pwm ntawm UV haum thiab kho, ntau xim xim ntawm number case uas yuav tsum tau kho lub sijhawm txawv. Raws li lub magenta lub teeb transmittance ntawm 50 rau 60%, 20 mus rau 30% daj, 8 mus rau 20% cyan, dub yog 12%, raws li xim ntawm 180-420nm UV absorption ntawm lwm, feem ntau UV number case screen kev txiav txim siab yog xim dub-cyan-yellow-poinsettia, uas tsis cuam tshuam rau UV kho tau tus nqi.
