Daim ntawv thov ntawm factorization hauv kev lag luam luam ntawv tau tsim sai heev. Cov ntaub ntawv UV tau siv dav hauv cov ntaub ntawv, cov ntaub ntawv, cov yas, cov khoom lag luam, daim npav sib nqus, cov ntawv lo thiab lwm yam khoom, thiab yuav luag txhua txoj kev luam ntawv tam sim no thiab cov qauv luam ntawv tau siv, thiab cov tshuab luam ntawv no yuav tsum tau nruab nrog UV tshuaj tshuab. Vim muaj ntau hom tshuab luam ntawv, muaj ntau hom kev kho tshuab. Kev xaiv UV curing tshuab feem ntau ua rau cov tuam txhab luam ntawv tsis meej pem.
Cov khoom tseem ceeb ntawm UV generator yog UV teeb thiab transformers. Tus yuam sij rau kev kho cov nyhuv yog kev xaiv thiab kev sib txuam ntawm qhov tsis sib xws ntawm UV teeb thiab transformer, kom lub teeb tuaj yeem ua tau zoo radiate 365 nm ultraviolet lub teeb. Tus sau tau koom nrog qhov kev tshawb fawb no tau ntau xyoo, thiab cov kev sim tau lees paub tias UV teeb hloov pauv yuav tsum yog qhov zoo sib xws. Nws tsis tuaj yeem yuav khoom sib cais. Yuav ua li cas phim thiab xaiv nws cov kev txwv? Tus kws sau ntawv tham txog qee qhov kev xav raws li nws qhov kev paub dhau los thiab sib tham nrog nws cov phooj ywg.
1,Kev txiav txim siab ntawm UV teeb parameter
1. Qhov tseem ceeb ntawm UV teeb: lub ntsiab wavelength (feem ntau, lub wavelength ntawm curing teeb nyob rau hauv printing yog 365 nm); Lub teeb arc ntev L (piv txwv li qhov ntev ntawm emitting ultraviolet lub teeb); Lub teeb raj tshwj xeeb ceev P. (tso zis zog ib centimeter, xws li 80 W / cm); Tag nrho lub teeb lub zog p; Lub teeb voltage U; Lub teeb tam sim no kuv; Tube txoj kab uas hla; Conductive khoom nyob rau hauv lub teeb raj, thiab lwm yam.
2. Kev txiav txim siab ntawm UV teeb tsis:
1) Lub teeb arc ntev L: Zui ntawm cov khoom kho tau ntxiv rau 2 cm dav;
2) Teeb lub zog ntom ntom P.: Thaum lub zog ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom P. Yog li ntawd, lub zog ceev yuav tsum raug xaiv raws li kev txav ceev ntawm cov khoom kho thiab cov yam ntxwv ntawm cov khoom kho.
3) Lub teeb tam sim no I: feem ntau, lub teeb tam sim no tsawg dua 10a, vim tias qhov tam sim no loj, qhov poob ntawm qhov hloov pauv yog qhov loj, thiab qhov tuab tuab ntawm qhov hloov pauv tau ua rau lub ntim loj ntawm lub transformer. Tab sis qhov tam sim no tsis tuaj yeem me me, feem ntau. Tam sim no ntawm lub teeb tuaj yeem hloov kho los ntawm transformer. Feem ntau, cov zis tam sim no ntawm high-speed leakage pin tsis raug kho rau Zui, thiab tom qab ntawd qhov tam sim no raug txo los ntawm lub capacitor. Zui tuaj yeem hloov kho rau 1-2a, tab sis tam sim no ntawm lub teeb tsis tuaj yeem hloov kho los ntawm lub capacitor.
4) Tag nrho lub teeb fais fab P=l zaus P.
5) Tube txoj kab uas hla: kev sim qhia tau hais tias yog tias qhov tam sim no ceev hauv lub teeb loj, cov khoom siv hluav taws xob ultraviolet yog siab. Piv txwv li, thaum lub raj phab ntsa ntawm 160W / cm2 yog 28 hli, ultraviolet siv yog 390W / cm2, thiab thaum lub raj phab ntsa ntawm 22.5MM, lub ultraviolet siv yog 620W / cm2. Thaum P. Tom qab kev txiav txim siab, lub zog thauj khoom ib cheeb tsam ntawm lub raj phab ntsa yog loj, lub raj phab ntsa kub yog siab, thiab lub teeb lub neej yog tsawg. Cov yeeb nkab phab ntsa kub tuaj yeem txo tau los ntawm cov dej txias lossis cua txias kom txhim kho lub neej kev pab.
6) Kev coj mus rau hauv lub teeb raj: UV teeb feem ntau yog mercury teeb thiab hlau halide teeb. Lub teeb mercury feem ntau yog siv rau kev siv hluav taws xob tsawg. Lub teeb mercury muaj ntau qhov tso zis ntau ntawm 365 nm. Feem ntau, lub zog nrog cov nyhuv kho yog 18% - 23% ntawm lub zog nkag, uas yog pom lub teeb thiab lub teeb infrared. Hlau halide teeb, los ntawm kev sib tov ob peb halides, ua kom cov zis hluav taws xob ntawm ultraviolet lub teeb, txhim kho warp fixation efficiency, thiab txo cov hluav taws xob hluav taws xob. Lawv feem ntau yog siv nyob rau hauv high-power density teeb. Mercury teeb muaj lub neej ua haujlwm ntev, feem ntau 600-2000 teev, thaum lub teeb halogen muaj lub neej ua haujlwm luv, feem ntau yog 200-1000 teev.
2,Kev txiav txim siab ntawm transformer parameter
Thaum xaiv lub transformer rau UV curing, cov nram qab no tsis tseem ceeb: input voltage, output voltage, input tam sim no thiab tam sim no. Txij li thaum lub teeb sab hauv ntawm lub teeb yog tias cov cathode emits kub electrons kom excite mercury molecules kom vaporize thiab ua hluav taws xob, thiab ionic conduction nyob rau hauv lub teeb hloov nrog cov txheej txheem vaporization ntawm mercury molecules, cov saum toj no tsis hloov, thiab feem ntau mus txog stability. tom qab 3-5 feeb. Cov hauv qab no piav qhia txog cov txheej txheem hloov pauv thiab xaiv txoj hauv kev ntawm ob peb qhov tseem ceeb.
1) Input voltage: 380V feem ntau yog xaiv raws li qhov input voltage ntawm transformers saum 3KW.
2) Cov zis hluav taws xob: qhov tso tawm qhov hluav taws xob qhib hluav taws xob yog 120% - 125% ntawm lub teeb tsim hluav taws xob, kom lub teeb tuaj yeem zoo siab qhib.
3) Cov zis tam sim no thiab cov zis hluav taws xob: Qhov hluav taws xob ntawm lub teeb txuas nrog lub tshuab hloov hluav taws xob yog qhov qhib hluav taws xob ntawm qhov hloov pauv, thiab lub teeb tam sim no yog xoom nyob rau lub sijhawm no. Nrog rau emission thiab conduction ntawm kub electrons, qhov voltage ntawm lub teeb poob sharply, thiab tam sim no nce raws li. Electrons sib tsoo nrog mercury molecules kom excite lawv, thiab lub zog ntawm electrons yog hindered. Tam sim no poob me ntsis, thiab qhov voltage nce. Thaum tag nrho cov supersaturated mercury yog vaporized thiab conductive, tam sim no nce mus rau lub xeev ruaj khov, thiab qhov hluav taws xob poob mus rau tus nqi ruaj khov.
3,Txoj kev dav dav ntawm kev xaiv UV teeb thiab transformer
Lub hom phiaj ntawm kev xaiv kom raug UV teeb thiab transformers yog kom ua tau zoo radiate ultraviolet rays nrog lub wavelength ntawm 365 nm. Cov ntsiab lus ntawm cov lus qhuab qhia hauv qab no yog qhia luv luv txog qee qhov kev ntsuas theoretically, yog li cov kev paub dhau los tseem ceeb heev thaum xaiv cov teeb thiab hloov pauv. Cov kev xaiv dav dav tau piav qhia hauv qab no.
1) Txiav txim siab lub teeb tsis thiab xaiv lub zog ceev raws li qhov yuav tsum tau kho. Piv txwv li, yog tias qhov curing ceev ntawm lub tshuab teb ceev ceev, lub zog yuav tsum yog 120-160w / cm. Yog tias lub tshuab luam ntawv ceev ntawm lub vijtsam yog qeeb, lub teeb nrog lub zog qis yuav tsum raug xaiv.
2) Xaiv lub teeb tam sim no. Yog tias tag nrho lub zog ntawm lub teeb yog 3-12kw, tam sim no yog 4.5-10a.
3) Xaiv qhov voltage, thiab tag nrho lub zog muab faib los ntawm qhov tam sim no yog tus nqi hluav taws xob. Piv txwv li, tag nrho lub zog yog 4kw, tam sim no yog 5.2a, thiab qhov hluav taws xob yog 770v.
Qhov tsis sib xws ntawm lub transformer yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm lub teeb, tab sis qhov loj tam sim no ntawm lub transformer yuav tsum siab tshaj qhov siab tshaj plaws tam sim no, uas feem ntau yog 120% ntawm qhov ua haujlwm tam sim no. Qhov hluav taws xob yuav tsum siv ntau tshaj peb pawg ntawm cov kais dej, vim tias qhov randomness ntawm lub teeb raj hauv cov txheej txheem tsim khoom loj thiab qhov tsis ruaj khov. Sim peb pawg ntawm cov kais dej ntawm lub tshuab hluav taws xob los ua kom cov zis hluav taws xob ntawm lub transformer ze rau qhov tseeb voltage ntawm lub teeb raj.
