LED ultraviolet teebyog ib qho tseem ceeb rau industrial curing. Tshwj xeeb UV lub teeb wavelengths ua rau cov ntaub ntawv photosensitive los teb tam sim ntawd. Lub tshuab no yog hloov cov roj teeb mercury thiab dhau los ua tus qauv rau kev tsim khoom zoo.
System Composition thiab Solidification Txoj Cai
Cov txheej txheem solidification yog photochemical. Thaum lub teeb lub teeb LED lub raj ultraviolet rays tsoo lub txheej, number case, los yog nplaum nrog photoinitiators, lawv nqus photons thiab tsim cov dawb radicals, uas ua rau monomers thiab prepolymers los ua ib lub network polymer. Nrog rau LED UV teeb qhov chaw, zoo heev tshav kub dissipation, ib tug zoo lub zog mov, thiab kho qhov muag lo ntsiab muag, lub kaw lus no ua kom muaj zog.
Cov txiaj ntsig kev ua tau zoo thiab cov khoom siv thev naus laus zis
LED UV curing system ua haujlwm zoo dua cov teeb mercury. Kev siv hluav taws xob qis qis los ntawm 70%, thiab nws hloov tam sim ntawd yam tsis muaj preheating. Lub teeb lub teeb tuaj yeem kav ntev dua 20,000 teev thiab tswj cov zis ruaj khov hauv ± 5%. Cov tshuab photoinitiator sib txawv tuaj yeem siv 365nm, 385nm, lossis 395nm wavelengths. Zam kev puas tsuaj rau substrate kub nrog 40% qis ua haujlwm kub dua li cov txheej txheem.
Qhov zoo ntawm LED UV
LED UVmuaj cov txiaj ntsig zoo dua cov teeb mercury thiab hlau halide teeb:
1. Lub neej ntev: Qhov nruab nrab lub neej ntev tshaj 50,000 teev. Mercury thiab hlau halide teeb kav ntev txog 900 teev.
2. Kev siv hluav taws xob tsawg: kev txuag hluav taws xob yog pom tau. Tsuas yog 10% mus rau 20% ntawm tus qauv UV teeb lub zog yog xav tau los kho. Ib txwm muaj mercury, hlau halide, thiab lwm yam teeb siv lub zog ntau. Tsuas yog ib nrab ntawm qhov ua tau zoo UV spectral ntau solidifies, thiab feem ntau yog poob li infrared thiab pom lub teeb.
3. Tsis tshua muaj kub: LED UV nto teeb qhov chaw kho cua sov- cov ntaub ntawv rhiab heev yam tsis muaj hluav taws xob infrared. Yog li, workpiece deformation yog txo. Ib txwm muaj mercury, hlau halide, thiab lwm yam teeb ci tawm ntau cov hluav taws xob infrared, uas tuaj yeem ua kom sov-deform tshav kub-sensitive workpieces. LED UV lub teeb qhov chaw feem ntau yog siv rau cov cua sov- cov khoom rhiab thiab nyias cov khoom nto lub teeb kho.
4. Tsis muaj consumables: Kev tu tsis pub dawb. Ib txwm muaj mercury, hlau halide, thiab lwm yam teeb pom kev zoo yuav tsum tau hloov lub raj thiab cov khoom siv ntau zaus, uas ua rau cov nqi kho mob tseem ceeb.
5. Tsawg- carbon thiab ib puag ncig tus phooj ywg: LED UV teeb qhov chaw tsis tso cov ntxhiab tsw, ozone, lossis mercury, uas txhawb kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig ntsuab. Tsoos mercury teeb, hlau halide teeb, thiab lwm yam tso tawm ozone thiab mercury, ua paug rau qhov chaw ua haujlwm.
LED UV teeb raj xa cov khoom siv kev pabcuam rau cov tuam txhab tsim khoom niaj hnub los ntawm kev txuag hluav taws xob thiab txhim kho cov txheej txheem kho nrog qhov tseeb wavelength tswj thiab cov zis ruaj khov.

FAQ
Q: Dab tsi yog qhov sib txawv ntawm LED ultraviolet teeb raj thiab cov roj mercury ib txwm muaj?
A: Qhov sib txawv tseem ceeb yog nyob rau hauv lub teeb emission txoj cai thiab spectral tso zis. LED ultraviolet teeb lub raj xa tawm lub teeb los ntawm cov khoom siv hluav taws xob, ua kom muaj qhov sib txawv ntawm cov wavelengths (xws li 365nm, 385nm, 395nm), thiab yog ib qho -peak txias qhov chaw. Cov teeb pom kev zoo mercury tso tawm lub teeb los ntawm cov pa tawm ntawm cov electrodes, tsim kom muaj tag nrho cov spectrum (xws li ultraviolet, pom lub teeb thiab infrared), uas muaj ntau qhov tsis zoo spectrum thiab cua sov.
Q: Yuav ua li cas xaiv lub wavelength tsim nyog (xws li 365nm vs 395nm) rau kuv daim ntawv thov?
A: Qhov kev xaiv nyob ntawm qhov nqus cov yam ntxwv ntawm photoinitiator. Lub 365nm wavelength yog luv dua thiab muaj zog dua me ntsis, uas feem ntau yog siv rau kev sib sib zog nqus curing thiab tsim nyog rau kev thov kev lag luam. Lub 395nm wavelength ntev dua thiab pom ntau dua violet lub teeb, tsis tshua muaj nqi, thiab yog siv dav hauv kev kho deg xws li ink curing thiab ntsia thawv kos duab. Nws yog ib qho tsim nyog yuav tsum tau xa mus rau cov lus pom zoo wavelength muab los ntawm tus neeg muab khoom siv.
