Feem ntau, UV luam ntawv muaj cov pawg thev naus laus zis hauv qab no:
1. Cov Khoom Siv Teeb UV
Qhov no suav nrog cov teeb, cov teeb ci ntsa iab, cov tshuab tswj hluav taws xob, thiab cov tshuab tswj kub (txias).
(1) Teeb
Cov teeb UV uas siv ntau tshaj plaws yog cov teeb mercury vapor, uas muaj mercury nyob hauv lub raj. Qee zaum, lwm cov hlau xws li gallium raug ntxiv rau los kho qhov tso zis spectral.
Cov teeb roj hlau-halide thiab cov teeb roj quartz kuj siv dav, thiab ntau yam tseem raug xa tuaj los ntawm txawv teb chaws.
Qhov ntau ntawm cov wavelength uas cov teeb UV curing tso tawm yuav tsum poob ntawm kwv yees li 200–400 nm kom ua haujlwm tau zoo rau kev kho.
(2) Cov khoom ci ntsa iab
Lub luag haujlwm tseem ceeb ntawm lub reflector yog los hloov cov hluav taws xob UV rov qab mus rau lub substrate kom ua kom cov khoom siv kho tau zoo dua (UV Tech Publications, 1991). Lwm lub luag haujlwm tseem ceeb yog los pab tswj kom lub teeb ua haujlwm tau zoo.
Cov reflectors feem ntau yog ua los ntawm txhuas, thiab qhov kev cuam tshuam feem ntau yuav tsum tau ncav cuag li 90%.
Muaj ob hom kev tsim qauv reflector yooj yim: focused (elliptical) thiab non-focused (parabolic), nrog rau lwm yam kev hloov pauv uas cov tuam ntxhab tsim.
(3) Cov Txheej Txheem Tswj Hluav Taws Xob
Cov txheej txheem no ua kom ntseeg tau tias cov UV tso zis tseem ruaj khov, tswj tau qhov ua tau zoo thiab sib xws thaum hloov kho rau ntau qhov ceev luam ntawv. Qee lub tshuab raug tswj hwm los ntawm hluav taws xob, thaum lwm lub siv kev tswj hwm microcomputer.
2. Cov Tshuab Txias
Vim tias cov teeb UV tsis yog tsuas yog tso tawm UV xwb tab sis kuj tseem muaj infrared (IR) cua sov, cov khoom siv ua haujlwm ntawm qhov kub siab (piv txwv li, qhov kub ntawm qhov chaw ntawm cov teeb quartz tuaj yeem ncav cuag ntau pua degrees Celsius).
Kub dhau heev yuav ua rau lub neej ntawm cov khoom siv luv luv thiab ua rau cov substrate nthuav dav lossis deformation, ua rau muaj qhov yuam kev sau npe thaum lub sijhawm luam ntawv. Yog li ntawd, cov txheej txheem txias yog qhov tseem ceeb heev.
3. Lub Tshuab Muab Kua Mis
Piv nrog cov kua mem offset ib txwm muaj, UV inks muaj viscosity siab dua thiab muaj kev sib txhuam ntau dua, thiab lawv yuav ua rau hnav cov khoom siv hauv tshuab xws li daim pam thiab cov menyuam.
Yog li ntawd, thaum lub sijhawm luam ntawv, cov kua mem hauv lub qhov dej yuav tsum tau sib xyaw tas li, thiab cov menyuam thiab cov pam hauv lub kaw lus kua mem yuav tsum yog cov ntaub ntawv tsim tshwj xeeb rau kev luam ntawv UV.
Yuav kom tswj tau qhov ruaj khov ntawm cov kua mem thiab tiv thaiv kev hloov pauv ntawm qhov kub thiab txias, cov txheej txheem tswj qhov kub ntawm cov menyuam kuj tseem ceeb heev.
4. Kev Tshem Tawm Kub thiab Cov Pa Tawm
Cov kab ke no tshem tawm cov cua sov ntau dhau thiab ozone uas tsim tawm thaum lub sijhawm polymerization thiab kho cov kua mem.
Lawv feem ntau muaj lub tshuab ua pa tawm thiab lub kaw lus ducting.
[Kev tsim cov ozone feem ntau yog txuam nrog UV wavelengths hauv qab ~ 240 nm; ntau lub tshuab niaj hnub no txo cov ozone los ntawm cov khoom lim lossis LED.]
5. Cov Kua Luam Ntawv
Qhov zoo ntawm cov kua mem yog qhov tseem ceeb tshaj plaws uas cuam tshuam rau cov txiaj ntsig ntawm kev luam ntawv UV. Ntxiv rau qhov cuam tshuam rau kev tsim cov xim thiab gamut, qhov kev luam tawm ntawm cov kua mem ncaj qha txiav txim siab qhov lo, lub zog, thiab kev tiv thaiv kev sib txhuam ntawm cov ntawv luam kawg.
Cov khoom ntawm photoinitiators thiab monomers yog qhov tseem ceeb rau kev ua tau zoo.
Yuav kom ntseeg tau tias muaj kev nplaum zoo, thaum cov kua UV ntub dej kov lub substrate, qhov nro ntawm lub substrate (dynes / cm) yuav tsum siab dua li ntawm cov kua mem (Schilstra, 1997). Yog li ntawd, kev tswj qhov nro ntawm ob qho tib si kua mem thiab lub substrate yog ib qho tseem ceeb hauv kev luam ntawv UV.
6. Cov Khoom Siv Ntsuas Zog UV
Vim tias tej yam xws li lub teeb laus zuj zus, lub zog hloov pauv, thiab kev hloov pauv ntawm qhov ceev ntawm kev luam ntawv tuaj yeem cuam tshuam rau kev kho, nws yog ib qho tseem ceeb uas yuav tsum saib xyuas thiab tswj kom lub zog UV ruaj khov. Yog li, kev ntsuas lub zog UV ua lub luag haujlwm tseem ceeb hauv kev luam ntawv UV.
