Ultraviolet radiation curing yog hais txog cov txheej txheem ua hauv cov tshuaj formula hloov los ntawm cov kua rau cov khoom los ntawm lub zog irradiation. Radiation curing feem ntau suav nrog ultraviolet curing, electron beam curing, thiab lwm yam. Tam sim no, ultraviolet curing muaj ntau yam kev siv hauv hluav taws xob kho tshuab, thiab infrared curing zog tsawg, thiab nws yog ib qho nyuaj rau ua rau luv luv saw cross-linking tshua. molecules. EB curing txwv nws daim ntawv thov vim nws cov cuab yeej siv loj.
1. Kev kho hluav taws xob
Radiation curing yog hais txog cov txheej txheem uas cov qauv tshuaj hloov pauv los ntawm cov kua rau cov khoom los ntawm kev siv hluav taws xob irradiation. Radiation curing mas suav nrog ultraviolet curing, electron beam curing, thiab lwm yam. Tam sim no, ultraviolet curing yog dav siv nyob rau hauv hluav taws xob curing technology. EB curing tau txwv nws daim ntawv thov vim nws cov cuab yeej siv loj. Yog li ntawd, dab tsi peb feem ntau hu ua lub teeb hluav taws xob kho feem ntau yog siv lub teeb ultraviolet.
2. UV curing
Lub hauv paus ntsiab lus ntawm UV curing yog tias los ntawm UV irradiation, lub photoinitiator absorbs lub teeb ntawm ib lub wavelength, generates dawb radicals los yog cations, pib lub polymerization thiab crosslinking ntawm monomers thiab oligomers, thiab generates ib tug network qauv nyob rau hauv ib tug luv luv lub sij hawm. Lub siab molecular hnyav polymer, thiab tom qab ntawd ua tiav kev kho.
Peb, UV LED curing kev lag luam saw
UV curing LED kev lag luam saw feem ntau suav nrog kev muab cov khoom siv raw, cov khoom siv kho, tshuaj formulations thiab cov neeg siv qis.
UV-kho cov ntaub ntawv raw yog cov khoom siv los ntawm cov khoom siv roj av. Nws feem ntau suav nrog cov monomers, oligomers, photoinitiators thiab additives (xws li cov neeg ua haujlwm theem, defoamers, cov neeg ua dej ntub dej, cov neeg ua hauj lwm plam, cov matting agents, stabilizers, pigments, solvents, thiab lwm yam). Lub oligomer yog cov pob txha yooj yim ntawm cov khoom siv photocurable, thiab nws cov khoom txiav txim siab cov khoom tseem ceeb ntawm cov txheej substrate tom qab kho (hardness, saj zawg zog, adhesion, optical zog, aging kuj, thiab lwm yam); lub monomer yog siv los yaj thiab dilute lub oligomer Nws yuav cuam tshuam rau cov tshuaj tiv thaiv tus nqi ntawm photocuring thiab kev ua tau zoo ntawm cov zaj duab xis zaum kawg; photoinitiator yog cov khoom tseem ceeb hauv photocuring system. Txawm hais tias tus nqi tsis loj, cov nyhuv tseem ceeb heev, txiav txim siab qhov curing ceev thiab curing zoo.
Cov khoom siv tshuaj lom neeg feem ntau yog xa mus rau cov coatings, inks, thiab adhesives, uas muab cov khoom siv rau cov neeg siv kawg UV curing daim ntaub ntawv.
Cov khoom siv kho yog hais txog kev muab cov khoom siv thiab cov khoom siv rau kev kho cov txheej txheem, uas feem ntau suav nrog cov khoom siv lub teeb xws li UV LED thiab cov khoom siv.
Cov neeg siv hauv qab, cov ntaub ntawv kho lub teeb muaj ntau yam kev siv, haum rau cov ntoo, yas, ntawv, hlau thiab lwm yam substrates, feem ntau yog siv hauv kev luam ntawv, txheej txheej, ntim, tsheb, khoom vaj khoom tsev, 3D luam ntawv, khoom siv hluav taws xob, kev kho mob, thiab lwm yam. . teb.
Qhov sib txawv ntawm cov tsoos tribute teeb thiab UV LED teeb dav siv tam sim no
1. Lub teeb UV LED yog ib lub teeb ci ib leeg, uas tsuas yog tsim cov wavelengths, uas muaj kev ntseeg siab dua rau tus neeg teb xov tooj.
2. Ultra-ntev lub neej ntawm UV LED teeb: Lub neej kev pab cuam yog ntau tshaj 10 npaug ntawm cov tsoos UV mercury teeb kho tshuab.
3. Lub teeb UV LED yog lub teeb txias txias, tsis muaj hluav taws xob thermal, thiab qhov kub thiab txias ntawm cov khoom illuminated yog tsawg, uas daws cov teeb meem thermal puas mus sij hawm ntev hauv kev sib txuas lus kho qhov muag thiab cov kua siv lead ua kua.
4. Kev tsim hluav taws xob tsawg ntawm UV LED teeb tuaj yeem daws qhov teeb meem ntawm cov khoom siv hluav taws xob kub siab ntawm mercury teeb luam ntawv thiab cov neeg ua haujlwm tsis muaj zog.
5. UV LED teeb tuaj yeem tig rau tam sim, thiab UV tso zis ntawm 100% lub zog tuaj yeem ncav cuag tam sim yam tsis muaj preheating.
6. Kev pabcuam lub neej ntawm UV LED tsis cuam tshuam los ntawm cov sijhawm qhib thiab kaw.
7. Cov teeb thiab teeb ci tsim los ntawm UV LED muaj lub teeb hluav taws xob hluav taws xob siab, lub teeb pom kev ruaj khov, cov nyhuv zoo irradiation, thiab txhim kho kev tsim khoom.
8. Qhov chaw irradiation tuaj yeem kho tau, qhov ntev yog los ntawm 7mm mus rau 1000mm.
9. UV LED tsis muaj mercury thiab tsis tsim ozone. Nws yog ib qho kev txhim khu kev qha thiab ib puag ncig zoo rau lwm txoj hauv kev rau cov khoom siv hluav taws xob.
10. UV LED lub zog siv qis dua, thiab kev siv lub zog tsuas yog 10% ntawm cov tsoos mercury teeb kho tshuab, uas tuaj yeem txuag tau 90% ntawm lub zog. Ib qho 50W UV LED taw qhia lub teeb tuaj yeem raug xa mus rau raws li ib txwm muaj 500W UV high-pressure mercury teeb.
11. Tus nqi txij nkawm ntawm lub teeb ci ntawm UV LED teeb yog yuav luag xoom. Rau
Qhov txawv ntawm UV LED taw tes teeb qhov chaw thiab ib txwm UV teeb:
Raws li lub cim tshiab ntawm kev txuag hluav taws xob thiab cov khoom siv ib puag ncig, UV LED txias lub teeb qhov chaw kho tshuab yog siv los kho cov xim pleev xim, thiab tam sim no siv ntau hauv kev lag luam. Dab tsi GMKJ LED xav qhia rau koj hnub no yog vim li cas ntau lub tuam txhab tau hloov cov roj mercury rau UV LED curing tshuab. Dab tsi yog qhov zoo ntawm UV LED curing tshuab? Dab tsi yog qhov zoo ntawm UV LED qhov chaw txias?
UV LED txias lub teeb ci tuaj yeem siv rau cov khoom siv cua sov. Nyob rau hauv qhov raug UV LED ultraviolet txias lub teeb qhov chaw, qhov kub ntawm qhov sib txawv ntawm cov khoom yuav tsis tshaj 1 ° C. Piv nrog rau lub teeb mercury ntawm qhov kub thiab txias, qhov kev siv tau nthuav dav heev. Qhov teeb meem ntawm qhov kub thiab txias ntau dhau tau raug daws ua ntej, thiab cov khoom yuav tsis raug puas tsuaj vim qhov kub ntawm cov khoom ntau dhau. Nws zam qhov kev tsim txom ntawm qhov kub thiab txias, ua kom yooj yim rau tib neeg lees txais, thiab tsis tsim cov pa phem thiab tsis kaj siab xws li ozone.
Kev ua haujlwm ntawm UV LED curing tshuab kuj yog siab heev. Lub zog ntawm UV LED curing tshuab tuaj yeem yog 100 % tso zis, thiab 100% ntawm lub zog yog siv los kho lub teeb-kho resin. Nrog 100% tso zis thiab 100% kev siv tus nqi, qhov curing efficiency yog qhov ceev tshaj plaws. Rau cov tsoos curing tos lub sij hawm ntawm kaum feeb, kaum feeb lossis txawm hnub, UV LED tuaj yeem ua tiav cov nyhuv curing hauv vib nas this, thiab qhov kho kom zoo kuj zoo heev. Ceev thiab zoo yog kev txhais lus muab los ntawm UV LED.
Tau kawg, muaj ntau qhov zoo ntawm UV LED ultraviolet lub teeb txias, nrog rau kev txuag hluav taws xob, lub neej ntev, kev tiv thaiv ib puag ncig thiab lwm yam. Yog tias koj muaj lus nug txog UV LED curing tshuab thiab xav sab laj, Taoyuan muab kev pabcuam.
