Hauv hnab looj tes tshuaj ntsuam luam ntawv, silicone yog dav siv los tsim cov logos, tuav cov qauv, thiab cov txheej txheem ua haujlwm. Txawm li cas los xij, ib qho tsis xws luag uas cuam tshuam rau kev luam ntawv zoo yog ntug los ntshav (tus number case kis dhau ntawm tus ciam ciam).
Vim li cas lub qhov dej zoo li - cov qauv luam tawm maj mam poob nws cov npoo ntse thiab pom qhov muag plooj lossis nthuav dav tom qab luam ntawv lossis kho?
Qhov teeb meem no tshwj xeeb tshaj yog nyob rau hauv kev luam ntawv ncaj qha ntawm cov ntaub panels los yog cov hnab looj tes tiav, qhov twg cov substrate yog hloov tau thiab absorbent heev. Feem ntau, ntug los ntshav tsis yog tshwm sim los ntawm ib qho tseem ceeb, tab sis los ntawm tus cwj pwm ntawm tus cwj pwm, kev nqus ntawm substrate, thiab cov txheej txheem tsis ruaj khov thaum luam ntawv thiab kho.
Dab tsi yog Edge Bleeding hauv Silicone Printing?
Ntug los ntshav yog hais txog kev sib kis tsis tau ntawm silicone number case dhau ntawm tus qauv tsim ciam teb, ua rau:
qhov muag plooj
ua kom loj luam ntawv loj
poob ntawm cov ntsiab lus zoo
tsis sib xws ciam teb txhais
Nws ncaj qha cuam tshuam rau ob qho tib si zoo li zoo thiab qhov tseeb ntawm qhov luam tawm.
Lub ntsiab ua rau Edge los ntshav ntawm hnab looj tes
1. Substrate Absorption thiab Fabric Structure
Cov khoom siv hnab looj tes xws li knitted polyester, nylon, lossis cov ntaub sib xyaw muaj:
ntxeem tau fiber ntau qauv
capillary absorption tus cwj pwm
tsis sib xws nto nro
Thaum siv silicone, nws tuaj yeem nkag mus rau hauv fiber ntau thiab kis tau tom qab ua ntej kho.
Qhov tshwm sim: tus number case migrate tshaj cov npoo npaj → los ntshav
2. Ink Viscosity thiab Flow Control
Silicone viscosity ncaj qha cuam tshuam rau ntug stability:
Tsawg viscosity → ntau dhau ntws
tsis zoo thixotropy tswj → tsis tswj kev sib kis
qeeb gelation → ntev ntws lub sij hawm ua ntej kho
Tus number case txuas ntxiv mus tom qab luam ntawv, ua rau ntug nthuav dav
3. Screen Mesh thiab Stencil Txhais
Screen parameters ua lub luag haujlwm tseem ceeb hauv ntug precision:
coarse mesh → ntau tus number case deposit
hnav stencil npoo → poob ntawm ntse txhais
tsis zoo emulsion tswj → tsis sib xws ciam teb tsim
Qhov tshwm sim: qauv npoo twb tsis ruaj khov ua ntej kho
4. Squeegee Pressure thiab Printing Technique
Manual printing qhia variability:
siab dhau → number case yuam tawm sab nraud
tsis sib xws stroke → inconsistent ntug tswj
lub kaum sab xis tsis raug → lateral ink displacement
Qhov no mechanical quab yuam thawb tus number case dhau ntawm tus ciam teb tsim
5. Kev kho ceev thiab tus cwj pwm kub
Curing txiav txim siab npaum li cas tus number case "locks" nyob rau hauv qhov chaw:
qeeb curing → ncua sij hawm txaus
cua sov tsis sib npaug → ncua ntug stabilization
nto daim tawv nqaij tsim → sab hauv txav mus ntxiv
Ink kis ua ntej puv gelation → ntug los ntshav tshwm sim
6. Fabric Tension thiab tuav cov xwm txheej
Thaum lub sij hawm luam ntawv thiab kho:
ntaub yuav ncab me ntsis
kev nro tuaj yeem tso tawm tsis sib xws
Kev txav mus los thaum lub sij hawm gel cuam tshuam rau cov duab number case
Qhov no ua rau distortion thiab ntug expansion ua ntej kawg kho
Yuav tiv thaiv Edge Bleeding li cas?
Txhawm rau txhim kho ntug sharpness hauv hnab looj tes silicone printing:
Siv silicone nrog tswj viscosity thiab ceev ceev - teeb tsa tus cwj pwm
Optimize mesh suav rau kev hloov tus cwj mem huv
Ua kom ruaj khov squeegee siab thiab lub kaum sab xis
Xyuas kom zoo stencil sharpness thiab screen mob
Tswj curing ceev kom txo tau ua ntej -gel txav
Stabilize ntaub nro thaum luam ntawv thiab kho
Xaus
Ntug los ntshav hauv silicone hnab looj tes luam ntawv tsis yog ib qho - cov ntsiab lus tsis raug. Nws yog qhov tshwm sim ntawm tus cwj pwm coj tus cwj pwm cuam tshuam nrog cov ntaub nqus dej thiab tswj cov txheej txheem thaum lub sijhawm ua ntej - kho.
Los ntawm kev tswj cov viscosity, txhim kho kev tshuaj ntsuam precision, thiab stabilizing curing tej yam kev mob, manufacturers tuaj yeem txhim kho ntug sharpness thiab luam ntawv txhais.
