Thaum siv lub tshuab luam ntawv UV flatbed los luam tawm qee cov ntaub ntawv, vim tias qhov ziab sai sai ntawm UV number case, nws qee zaum ua rau muaj teeb meem ntawm qhov qis adhesion ntawm UV number case rau substrate.Kab lus no yog los kawm txog yuav ua li cas los txhim kho qhov adhesion ntawm UV number case rau substrate.
kho mob corona
Tus sau tau pom tias kev kho mob corona yog ib txoj hauv kev uas tuaj yeem txhim kho qhov adhesion ntawm UV number case!Qhov zoo thiab tsis zoo electrodes ntawm corona ntaus ntawv yog grounded rau hauv av dav hlau thiab lub Yuden cua nozzle feem.Cov hluav taws xob dawb nrog lub zog siab yog nrawm rau qhov zoo electrode, uas tuaj yeem hloov pauv polarity ntawm cov khoom tsis nqus dej thiab ua kom lub ntsej muag roughness, txhim khu lub peev xwm los ua ke nrog tus cwj mem, ua tiav qhov tseeb UV number case adhesion, thiab txhim kho cov adhesion. fastness ntawm tus number case txheej..
Corona-kho cov ntaub ntawv muaj qhov tsis zoo ntawm qhov nro ruaj khov, thiab cov nyhuv corona yuav maj mam poob qis thaum lub sijhawm.Tshwj xeeb tshaj yog nyob rau hauv ib puag ncig high humidity, cov nyhuv corona yuav tsis muaj zog sai.Yog tias corona kho substrates raug siv, kev koom tes nrog tus neeg muag khoom yuav tsum tau ua kom ntseeg tau tias qhov tshiab ntawm cov substrates.Cov khoom siv kho mob corona xws li PE, PP, nylon, PVC, PET, thiab lwm yam.
UV number case adhesion txhawb nqa (AdhesionPromoters)
Feem ntau, ntxuav lub substrate nrog cawv yuav txhim kho qhov adhesion ntawm UV number case rau substrate.Yog tias qhov adhesion ntawm substrate rau UV number case yog qhov tsis zoo, lossis cov khoom lag luam muaj cov kev xav tau siab rau qhov adhesion ntawm UV number case, koj tuaj yeem txiav txim siab siv primer / UV number case adhesion uas txhawb nqa qhov adhesion ntawm UV number case.
Tom qab cov primer yog siv rau ntawm lub substrate uas tsis yog-absorbent, lub adhesion ntawm UV number case tuaj yeem txhim kho kom ua tiav qhov zoo tshaj plaws adhesion nyhuv.Sib txawv ntawm kev kho mob corona, cov khoom siv ntawm cov tshuaj primer tsis muaj cov tsis muaj polar oily molecules, uas tuaj yeem tshem tawm cov teeb meem tsis ruaj khov corona tshwm sim los ntawm kev tsiv teb tsaws ntawm cov molecules.Txawm li cas los xij, qhov kev thov ntawm primer yog xaiv, thiab nws zoo dua rau iav, ceramic, hlau, acrylic, PET thiab lwm yam substrates.
UV number case curing degree
Feem ntau, peb tuaj yeem pom qhov tsis zoo ntawm UV inks ntawm cov khoom tsis nqus dej hauv cov xwm txheej uas UV inks tsis kho tag nrho.Txhawm rau txhim kho qhov curing degree ntawm UV number case, koj tuaj yeem pib los ntawm cov hauv qab no:
1) Ua kom lub zog ntawm UV teeb kho lub teeb.
2) Txo cov luam ntawv ceev.
3) Txuas lub sijhawm kho.
4) Xyuas seb lub teeb UV thiab nws cov khoom siv puas ua haujlwm zoo.
5) Txo cov thickness ntawm cov number case txheej.
Lwm txoj kev
Cua sov: Hauv kev lag luam tshuaj ntsuam luam ntawv, nws raug nquahu kom sov lub substrate ua ntej UV curing ua ntej luam tawm ntawm qhov nyuaj-rau-adhere substrates.Lub adhesion ntawm UV inks rau substrates tuaj yeem txhim kho tom qab cua sov nrog ze-infrared lossis far-infrared teeb rau 15-90 vib nas this.
Varnish: Yog tias UV number case tseem muaj teeb meem ua raws li lub substrate tom qab siv cov lus qhia saum toj no, cov kua roj vanish tuaj yeem siv rau saum npoo ntawm cov ntawv luam tawm.
