Hauv hnab looj tes tshuaj ntsuam luam ntawv, silicone yog dav siv los tuav, tiv thaiv, thiab kho kom zoo nkauj. Txawm li cas los xij, ib qho kev tsis xws luag uas feem ntau tshwm sim hauv kev tsim khoom yog wrinkling lossis tsis sib xws ntawm qhov chaw tom qab kho.
Vim li cas cov ntawv luam tawm silicone uas zoo li du thaum luam ntawv tig mus rau hauv qhov tawv nqaij los yog tsis sib xws tom qab ziab lossis cua sov?
Qhov teeb meem no yog tshwj xeeb tshaj yog nyob rau hauv kev luam ntawv ncaj qha rau ntawm txiav panels los yog tiav cov hnab looj tes, qhov twg lub substrate yog hloov tau thiab tsis tu ncua nyob rau hauv nruj. Feem ntau, wrinkling tsis yog tshwm sim los ntawm ib qho yuam kev, tab sis los ntawm kev sib cuam tshuam ntawm cov khoom ntws, substrate txav, thiab kho cov mob.
Dab tsi yog Silicone Wrinkling hauv hnab looj tes Printing?
Silicone wrinkling yog hais txog qhov tsis yog -ib puag ncig deformation tom qab kho, qhov twg cov txheej luam tawm tshwm:
tsis sib xws
folded los yog rippled
hauv zos compressed los yog distorted
Nws feem ntau cuam tshuam rau cov tsos, tuab tuab, thiab qee zaum, kev ua haujlwm zoo xws li tuav lossis elasticity.
Cov laj thawj tseem ceeb ntawm Silicone Wrinkling
1. Substrate Movement thaum luam ntawv thiab kho
Cov ntaub ntawv hnab looj tes xws li knitted fabrics lossis hluavtaws fibers yog hloov tau yooj yim. Thaum lub sij hawm luam ntawv thiab cua sov, cov ntaub yuav:
stretch me ntsis
shrink nyob rau hauv tshav kub
los yog txav mus los vim yog kev tawm dag zog
Yog tias cov silicone tseem nyob hauv ib nrab - kua lossis gel lub xeev thaum lub sijhawm txav no, qhov saum npoo yuav deform.
Qhov tshwm sim: tsis sib npaug ntawm qhov nro → wrinkling tom qab kho
2. Ntau tus Ink Thickness lossis tsis sib xws
Hauv kev tshuaj ntsuam luam ntawv, silicone thickness yuav tsum tau tswj.
Ntau tus number case → nto tsis tuaj yeem sib npaug
Tsis sib npaug mesh tso tawm → hauv zos tsub zuj zuj
Thaum lub sij hawm kho, cov cheeb tsam thicker shrinks txawv ntawm qhov chaw thinner.
Qhov sib txawv no tsim qhov nro qhov tsis sib xws → wrinkles daim ntawv
3. Mesh & Screen tswj teeb meem
Lub mesh system ncaj qha cuam tshuam rau tus lej faib:
Tsawg mesh sib xws → tsis sib xws deposit
Tsis zoo emulsion thickness → irregular flow
Yog tias cov khoom siv silicone tsis sib npaug, cov txheej txheem kho yuav ua kom muaj qhov sib txawv no.
Qhov tshwm sim: nto deformation tom qab tshav kub kho
4. Squeegee Pressure thiab Printing Technique
Phau ntawv los yog ib nrab - tsis siv neeg luam ntawv qhia kev hloov pauv:
Kev kub siab dhau → ntau dhau tus cwj mem thawb
Tsis sib xws stroke → inconsistent txheej thickness
Lub kaum sab xis → tsis zoo leveling
Qhov no ua rau kom tsis ruaj khov number case → wrinkled nto tom qab kho
5. Kho qhov kub thiab txias faib
Kev kho yog ib qho tseem ceeb tshaj plaws.
Qhov kub tsis sib xws
Overheating txheej txheej
Kev kho sab hauv tsis tiav
Thaum silicone kho tsis sib xws, ntau qhov chaw sib txawv ntawm cov nqi sib txawv.
Qhov kev tsis txaus ntseeg no yog qhov ua rau ntawm qhov chaw wrinkling
6. Silicone khoom ntws tus cwj pwm
Cov txheej txheem silicone sib txawv muaj qhov sib txawv:
viscosity
leveling peev xwm
kho ceev
Yog tias cov khoom siv ceev dhau - kho lossis siab dhau -viscosity:
nws tsis tuaj yeem ua tus kheej - theem ua ntej gelation
Qhov tshwm sim: khov nto zoo nkauj → wrinkled tsos
Yuav tiv thaiv Silicone Wrinkling ntawm hnab looj tes li cas?
Yuav kom txo tau cov teeb meem wrinkling, tag nrho cov txheej txheem yuav tsum tau tswj:
Sib phim silicone viscosity nrog ntaub hom
Tswj tus number case thickness thiab zam dhau - tso nyiaj
Siv cov mesh ruaj khov thiab teeb tsa stencil zoo ib yam
Tuav lub squeegee siab thiab lub kaum sab xis
Xyuas kom ruaj khov curing kub thiab airflow
Tsis txhob txav cov ntaub thaum lub sijhawm kho thaum ntxov
Xaus
Silicone wrinkling ntawm hnab looj tes tsis yog ib qho teeb meem -. Nws yog qhov tshwm sim ntawm kev sib cuam tshuam tsis sib xws ntawm cov kua dej ntws, kev txav ntawm cov substrate, thiab kev coj tus cwj pwm.
Los ntawm kev tswj cov deposition sib xws, cov khoom ntws, thiab kho stability, manufacturers tuaj yeem txhim kho qhov smoothness thiab cov khoom zoo.
