Qhia txog luv luv ntawm daim ntawv tso cai thiab zoo ntawm UV number case
Peb yog ib lub lag luam loj hauv Shenzhen Tuam Tshoj. Peb muaj cov phau ntawv luam tawm, phau ntawv nyuaj, phau ntawv luam ntawv, phau ntawv nyuaj, phau ntawv luam tawm, phau ntawv luam tawm, phau ntawv luam tawm, lub thawv ntim, daim qhia ntawv, txhua yam ntawm PVC, cov ntawv luam tawm, ntawv sau cia, hom tshwj xeeb ntawv xim luam tawm khoom, kev ua si cardand li ntawd.

Nyob rau hauv xyoo tas los, UV inks tau dhau los thiab ntau dav siv los ua tus pheej loj tshaj plaws hauv cheeb tsam zoo hauv phom, thiab lub ntiaj teb no UV lag luam yog nce ntawm 10% toj ib xyoo.
Yuav kom muaj kev sib tw ua lag luam, cov tuam txhab luam ntawv yuav tsum txhim kho cov khoom kom zoo, yog li ntawd lawv yuav tsum xaiv cov khoom siv thiab cov khoom siv hluav taws xob. Txij thaum UV inks muab tshwj xeeb tus nqi rau cov luam tawm, lawv siv yog nce.
Hauv kev tshavpuam ntawm luam ntawv, UV offset luam ntawv tau dhau los ua ib qho tseem ceeb rau cov phau ntawv npog, kev tshaj tawm txog kev tshaj tawm, thiab kho kom zoo nkauj. Vim hais tias ntawm qhov zoo nkauj zoo ntawm UV number case, nws tsis muaj cov tshuaj tsis haum xeeb thiab kev kho sai sai, thiab nyiam cov neeg. Daim ntawv thov UV ua haujlwm hauv offset luam ntawv tau qhia tias kev loj hlob zoo.
Ua ntej, daim ntawv thov txheej txheem ntawm UV number case
Lub ntsiab Cheebtsam ntawm UV number case muaj xws li cov organic pigment, prepolymerable photolymerable, monoensens monomer, photopolymerization initiator, thiab cov zoo li. Cov teebmeem ntawm txhua feem tau qhia nyob rau hauv Table 1.
UV thom daws teebmeem qhov teebmeem hauv kev luam tawm nrog lawv txoj kev kom qhuav. Nws cov ntsiab lus qhuav yog ua kom muaj yees duab ntawm tus cwj pwm ntawm ultraviolet radiation rau tus cwj mem, uas ua kom tiav lub hom phiaj ntawm kev kho lub cwj mem. UV inks muaj cov nram qab no ob lub ntsiab kev tshuaj lom neeg thaum lub caij ziab khaub ncaws.
Photochemical ras txog
Lub photopolymerization initiator muaj nyob hauv tus number case undergoes ib lub yeeb yam muaj yees duab nyob rau hauv ultraviolet hluav taws xob kom tsim muaj radical.
Chain ras txog
Cov teeb meem ntawm lub yeeb yaj kiab tau ua rau cov neeg muaj peev xwm ua tau zoo, thiab cov ntawv ua kom tsis muaj zog, thiab kev ua kom cov ntsej muag tsis muaj zog, cov khoom ua ntsej muag polyfunctional, tus neeg saib xyuas lub ntsej muag, thiab cov lus sib dhos rau hauv cov cwj mem zauv. Ib cov khoom siv luam yeeb uas muaj cov qauv peb sab - ib zaj duab xis qhuav.
Yog li, qhov ziab ntawm UV number case feem ntau yog nyob ntawm cov ziab khoom ntawm cov luam ntawm photocuring, xwv li tias tus number case muaj qhov sib txawv ziab khoom nyob rau hauv cov xwm txheej tau txais lub teeb thiab tsis muaj teeb meem ntawm lub teeb, uas yog, tus number case tsis tau lub teeb thaum lub sij hawm luam ntawv, thiab tswj cov khoom qub ruaj khov, thiab muaj cov khoom zoo. Kev luam xeev; tom qab luam ntawv, nws yog irradiated los ntawm ultraviolet lub teeb thiab qhuav sai sai, uas tuaj yeem ntsib cov haujlwm tom qab, ua kom zoo tshaj qhov qub, thiab ua kom zoo dua ntxiv ntawm tus lej ntawm tus lej ziab.
Qhov thib ob, qhov zoo ntawm UV number case
1. Lub cev tsis muaj zog
Feem ntau cov khoom UV muaj tsawg tsawg los sis tsis muaj cov organic solvents, thiab tsis muaj qhov hnyav tua kom raug cov teeb meem luam tawm thiab ua rau tib neeg lub cev thiab qhov chaw tsis zoo.
2. Haum rau cov ntawv tsis substrates
Nws tuaj yeem sau rau ntawm cov khoom siv los sis cov ntaub ntawv uas tsis yog khoom siv xws li zaj duab xis, hluavtaws, hlau lossis yas.
3. Haum rau kev xa xov tom qab pib
Nws tuaj yeem kho sai sai tom qab kis tau tus kab mob ultraviolet.
4. Siv tus cwj mem tsawg dua
Vim tias tus UV number case tsis muaj qhov hnyav, nws tsuas yog yuav tsum siv tus lej ntawm 1/3 txog 1/2 ntawm tus nqi ntawm tus cwj pwm pa kom tau cov nyhuv yam xav tau.
5. Muaj peev xwm ua kom muaj xim sib txawv
Los ntawm kev kho lub viscosity, hue thiab lightness ntawm tus number case, koj tuaj yeem ntxiv nplua nuj xim. Koj tuaj yeem tau txais ntau yam xim yam xim los ntawm ob los yog ntau cov xim yooj yim.
6. Kev yoojyim yog qhov yooj yim los tswj
Cov pigment lossis pigment tuaj yeem raug ntxiv rau lub nrug sab nraud kom tiav qhov kev ntshaw raws li tus qauv ntsuas.
7. UV number case tuaj yeem ua haujlwm nyob rau hauv tshwj xeeb luam ntawv xws li dej khov, tawg, txhaws thiab pob tw.
