Rov qab
Kab lus no piav qhia yuav ua li cas txhawm rau txhim kho UV number case adhesion, qhov tseem ceeb ntawm kev xaiv qhov chaw tsim nyog (lossis substrate), thiab lub luag haujlwm ntawm pretreatment.
Cov yam ntxwv cuam tshuam rau UV Ink Adhesion
Rautxhim kho qhov nplaum ntawm UV number case, koj yuav tsum xub nkag siab tias yam dab tsi cuam tshuam rau nws. Nov yog cov yam tseem ceeb:Cov khoom siv substrate
Hom ntaub ntawv uas koj luam tawm cuam tshuam zoo npaum li cas tus number case adheres. Nto textures sib txawv ntawm cov ntaub ntawv xws li yas, hlau, thiab ntawv. Piv txwv li, sleek polymers thiab hlau yuav tsis tuav tus number case los yog rougher nto zoo li ntawv. Paub seb koj cov khoom yuav ua li casUV ink tso cai rau koj ua qhov kev hloov kho uas tsim nyog.Piv txwv li, piv cov ntaub ntawv yas zoo nkauj nrog ib tus du kom nkag siab qhov sib txawv ntawm kev ua raws.
Nto Zog
Surface zog ntsuas li cas cov khoom ntawm daim ntawv cog lus rau number case. Cov ntaub ntawv uas tsis tshua muaj zog saum npoo av, xws li qee cov yas, tsis lees txais tus number case. Kev kho ua ntej tuaj yeem ua kom lub zog saum npoo av, tso cai rau tus cwj mem kom lo zoo dua.Polyethylene thiab polypropylene yogcov plastics uas tsis tshua muaj zog; corona los yog nplaim taws kho tuaj yeem pab txhim kho tus cwj mem adhesion.
Ink Composition
Qhov sib xyaw ntawm UV number case kuj cuam tshuam rau kev ua raws. Qee cov inks yuav tuab dhau los yog qhuav sai heev, ua rau lawv nyuaj rau lo rau saum npoo. Nrhiav qhov sib npaug tsim nyog hauv covtus number case formulation ua rau nws lo rau ntawm qhov chaw.Ntsuam xyuas cov txheej txheem sib txawv ntawm ib cheeb tsam me kom pom qhov zoo sib xws rau koj cov substrate.
Txoj kev Deg Pretreatment
Zoo adhesion yuav tsum tau npaj nto kom zoo ua ntej luam ntawv. Nov yog qee qhovcov tswv yim nrov los npaj koj qhov chaw:Kev kho mob Corona
Kev kho mob Corona ntiav cov hluav taws xob hluav taws xob hluav taws xob siab los txhawb lub zog saum npoo ntawm cov khoom xws li polymers. Nws ua rau saum npoo ntau "wettable," cia tus number case los lo zoo dua.Ib daim ntawv thov raug rauyas zaj duab xis cov ntaub ntawv nyob rau hauv ntim qhov twg corona kev kho mob txhim kho qhov luam tawm ntawm qhov chaw.
Kev Kho Mob Plasma
Kev kho ntshav plasma hloov cov khoom siv qhov chaw siv cov roj tshwj xeeb. Txoj kev no ua rau nws yooj yim dua rau UV number case kom ua raws, thiab nws muaj txiaj ntsig zoo rau cov ntaub ntawv uas nyuaj rau luam tawm. Plasma kev kho mob tau txais txiaj ntsig zoo li cov iav lossis ceramics, qhov twg cov txheej txheem ib txwm ua tsis tau zoo.Tshuaj Priming
Koj tab tom thov cov tshuaj priming lossis tshuaj tshwj xeeb ua ntejprinting pab ink adhesion. Primers ntxiv dag zog rau kev sib raug zoo ntawm tus cwj mem thiab qhov chaw, txhawb kev ua raws. Xaiv cov primer uas sib haum nrog koj ob lub substrate thiab tus cwj mem.Xav txog kev siv etching primer rautxhim kho tus cwj mem ua raws li kev luam ntawv ntawm cov hlau.
Yuav Ua Li Cas Txhim Kho UV Ink Adhesion?
Nov yog qhov koj tuaj yeem xyaum txhim kho UV number case adhesion:Kho Chaw Sau Ntawv
Koj lub tshuab luam ntawv teeb tsa tuaj yeem cuam tshuam rau kev ua raws li tus lej. Xyuas kom koj lub tshuab luam ntawv lub teeb UV teeb rau lub zog tsim nyog thiab lub sijhawm raug. Kev kho kom raug kom ntseeg tau tias tus number case adheres zoo thiab dries kom raug.Khiav ib qho kev sim luam tawm ntawm cov teeb sib txawv kom pom lub sijhawm zoo tshaj plaws rau koj qhov chaw tshwj xeeb.
Khaws Koj Cov Khoom Siv
Khaws kojtshuab luam ntawv huv si thiab ua haujlwm zoo yog qhov tseem ceeb. Cov khoom qias neeg los yog hnav-tawm, xws li cov menyuam thiab cov taub hau luam tawm, cuam tshuam rau daim ntawv thov thiab kev ua raws. Kev saib xyuas tsis tu ncua pab kom tsis txhob muaj kev txhawj xeeb no.Lub sijhawm tu txhua lub limtiam rau cov ntawv luam tawm tuaj yeem txo qiscov teeb meem cuam tshuam txog kev kis tus lej unevenly los tsis stick.
Ntsuas thiab ntsuas
Ua ntej luam tawm ib pawg loj, sim cov khoom sib txawv thiab hom number case kom pom qhov zoo tshaj plaws ua ke. Tshawb xyuas koj cov ntawv luam tawm ntau zaus kom paub tseeb tias tus number case sticks zoo. Txoj kev no, koj tuaj yeem hloov kho ua ntej pib qhov project loj.Khaws cov ntaub ntawv ntawm koj qhov kev xeem, suav nrog hom number case, kev kho saum npoo, thiab ib puag ncig, txhawm rau txhim kho koj cov txheej txheem luam ntawv.
Ink Selection thiab Optimization
Xaiv tus cwj mem kom raug thiab kho nws rau kev ua tau zoo dua yog qhov tseem ceeb rau kev ua kom zoo:Xaiv High-Quality UV Inks
Kev nqis peev hauv UV inks qhia meej tsim rau cov ntaub ntawv koj siv yog qhov tseem ceeb.High-quality inks feem ntau muab superior adhesion, durability, thiab xim sib xws. Tsis txhob siv cov inks generic, uas tej zaum yuav ua tsis tau zoo.Saib rau UV inks tailored rau tej qhov chaw, xws li hlau los yog yas, thiab xyuas cov chaw tsim tshuaj paus cov lus qhia rau cov neeg siv zoo tshaj plaws.
Kho Ink Viscosity
Lub thickness ntawm tus number case (lub npe hu ua viscosity) txiav txim siab npaum li cas nws sticks. Xyuas kom tseeb tias koj tus number case tsis tuab dhau los yog nyias dhau. Qhov tsim nyog viscosity txhim kho number case adhesion thiab ua rau cov luam ntawv du.Kho tus cwj mem viscosity raws li koj qhov chaw nyob ib puag ncig - qhov sov sov tuaj yeem xav tau me ntsis cov ntawv tuab los tiv thaiv kev sib kis ntau dhau.
Xav txog Ink Additives
Qee qhov UV inks muaj cov khoom xyaw tshwj xeeb uas txhawb nqa kev ua raws. Cov tshuaj no pab tus number case ua kom zoo dua rau qhov chaw nyuaj. Sim tawm ntau tus cwj mem formulations tuaj yeem pab koj nrhiav qhov zoo tshaj plaws rau koj cov kev xav tau.Yog tias koj tab tom ntsib cov kev sib tw nrog cov chaw slick, tshawb xyuas cov tshuaj pleev xim uas tsim los txhim kho kev ua raws li cov ntaub ntawv glossy.
