Cov yam ntxwv cuam tshuam rau Lamination zoo hauv ntim luam ntawv
Thickness thiab cheeb tsam ntawm Ink Layers nyob rau hauv ntim Printing:Qee cov ntawv ntim khoom muaj cov duab kos duab dav dav, thiab qee qhov cuam tshuam nrog cov khoom luam ntawv, ua rau cov xim tuab tuab. Cov khaubncaws sab nraud povtseg tuab tuaj yeem tsim teeb meem hauv kev ua raws li cov yas zaj duab xis, ua rau delamination thiab bubbling sai tom qab kev sib txuas. Qhov no yog vim cov txheej tuab tuab hloov cov yam ntxwv ntawm cov ntawv ntxeem tau, kaw cov ntawv fibers 'capillaries thiab cuam tshuam cov nplaum nkag mus thiab sib kis. Lub adhesion lub zog yog qhov cuam tshuam loj heev, thiab kev hloov pauv hauv cov xim txheej tuab thiab thaj chaw tuaj yeem hloov kho qhov nro, cuam tshuam rau kev sib koom ua ke. Kev tswj nruj dhau ntawm cov kua txob thiab cov txiaj ntsig zoo nkauj yog qhov tseem ceeb thaum lub ntxa luam tawm tas li (feem ntau tswj tau ntawm {{μm) rau kev ua lamination zoo.
Ink Selection rau Ntim Printing:Rau cov khoom laminated hauv ntim luam ntawv, ceev ceev-drying glossy offset printing inks raug pom zoo. Cov inks, muaj li ntawm hluavtaws resins, qhuav zaub roj, thiab high-boiling-point kerosene, txhawb cross-linking, tsim muaj zog lub cev thiab tshuaj bonds conducive rau lamination. Kev saib xyuas yuav tsum tsis txhob siv cov roj av ntau dhau, vim tias nws tuaj yeem ua rau kom qhuav sai heev, cuam tshuam rau cov txiaj ntsig lamination. Tsis tas li ntawd, thaum luam ntawv lub teeb xim, diluting cov neeg sawv cev yuav tsum tau ntxiv, nrog cov zoo diluting agents yog nyiam.
Daim ntawv thov ntawm Printing Powder:Txhawm rau kom haum rau kev kub ceev luam ntawv ntawm cov tshuab ntau xim thiab tiv thaiv cov ntawv rov qab los ntawm cov ntawv luam tawm thaum luam ntawv, cov txheej txheem hmoov yog feem ntau ua hauj lwm hauv ntim offset printing. Cov hmoov, feem ntau muaj cov hmoov txhuv nplej siab nplej siab thiab cov tshuaj tiv thaiv ntuj, yuav tsum tau ua tib zoo tswj kom tsis txhob siv ntau dhau. Over-powdering tuaj yeem ua rau cov khoom ua kom ntab rau ntawm qhov chaw luam ntawv, cuam tshuam cov nplaum nplaum thaum lub sij hawm lamination thiab cuam tshuam rau lamination zoo.
Surface thiab Inner Drying conditions of Printed Products:Kev ziab tsis zoo ntawm qhov chaw lossis cov khaubncaws sab nraud povtseg ntawm cov khoom luam tawm tuaj yeem cuam tshuam qhov zoo ntawm lamination, ua rau muaj teeb meem xws li bubbling thiab delamination. Ntau yam, suav nrog hom number case, tus neeg saib xyuas kom qhuav kom muaj nuj nqis, daim ntawv qauv, thiab qhov chaw ua haujlwm kub thiab av noo, cuam tshuam rau qhov ziab ntawm number case txheej. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tsum tau them tshwj xeeb rau cov number case txheej kom qhuav thaum luam ntawv. Kev tswj nruj ntawm tus lej-dej sib npaug, saib xyuas tus lej emulsification tej yam kev mob, thiab tswj cov kua qaub ntawm cov ciav dej yog qhov tseem ceeb. Kev tswj xyuas qhov ntsuas kub thiab cov av noo kom zoo ua kom ob qho tib si saum npoo thiab sab hauv txheej ntawm cov ntawv ntim khoom kom qhuav, lav qhov zoo ntawm lamination.
