UVLED Curing Txoj Cai

Qhov thiaj li hu ua UVLED curing yog ntxiv lub teeb ua rau cov resin hauv cov mis tshwj xeeb. Tom qab absorbing lub siab-lub zog ultraviolet lub teeb nyob rau hauv lub UVLED kho qhov muag ntaus ntawv, active dawb radicals los yog ion bases yog generated, uas ua rau aggregation, cross-linking thiab ceg rau react, yog li ntawd cov resin reactor ua rau resin (UV xim, number case, adhesive, thiab lwm yam) los ntawm cov kua mus rau lub xeev khov nyob rau hauv ob peb feeb. Lub cev muaj zog ntawm UVLED curing cov ntaub ntawv yog qhov tseem ceeb cuam tshuam los ntawm UV-optical curing tshuab. Qhov kev ua tau zoo, txawm tias nws yog kev tiv thaiv cov kua nplaum, cov kua nplaum, lossis cov nplaum, nws yuav nyob ntawm qhov tsis muaj, tsim thiab tswj cov txheej txheem ntawm LED chips hauv cov tshuab kho. Plaub qhov tseem ceeb ntawm LED nti yog: 1.UV hluav taws xob (los yog qhov ntom ntom) 2. spectral faib (wavelength) 3. Radiation (los yog UV zog) 4. Cov hluav taws xob hluav taws xob yog txheeb ze rau cov hluav taws xob loj lossis hluav taws xob ntim, thiab cov khoom sib txawv, thiab cov sib txawv UVLED spectrum, number case thiab cov kua nplaum tiv thaiv yuav qhia cov yam ntxwv sib txawv. Lub peev xwm los txheeb xyuas cov yam ntxwv ntawm LED nti sib txawv thiab ua kom lawv phim cov yam ntxwv kho qhov muag ntawm cov ntaub ntawv kho, thiab nthuav dav qhov kev sib zog ntawm UVLED raws li cov txheej txheem tsim khoom sai thiab muaj txiaj ntsig. Muaj ntau yam khoom siv kho qhov muag thiab lub cev ntawm cov txheej txheem kho uas cuam tshuam rau cov nyhuv solidification, uas ua rau qhov sib txawv ntawm cov yam ntxwv ntawm UV kho cov ntaub ntawv. Cov txiaj ntsig ntawm cov tsis muaj feem cuam tshuam rau UV kho kom zoo 1. UVLED tshuab wavelength: Lub spectrum ntawm 365nm band yog haum rau cov tib neeg kho qhov muag number case (tsis haum rau tus number case yuav tsum tau tshwj xeeb spectrals xws li ice paj thiab wrinkles). Qee lub tshuab UV ntau dhau los ntawm kev cuam tshuam ntawm LED nti, uas yuav cuam tshuam rau lub teeb pom kev zoo. Nws raug pom zoo tias cov neeg siv khoom ua lub teeb pom kev zoo thaum xaiv UV teeb kho cov cuab yeej los kuaj seb lub wavelength ntawm UV tshuab ua tau raws li qhov xav tau ntawm cov khoom kho qhov muag. 2. Lub zog ntawm UVLED tshuab: Feem ntau, lub zog xav tau los ntawm UV optical number case yog 80-120MW / CM, thiab lub zog nqus lub teeb yog li 2000 3000mJ / cm. Ntau lub teeb lub zog tuaj yeem ua rau brittleness ntawm number case. Low-low light solid effect. Daim ntawv thov piv txwv UV lub teeb hluav taws xob lub cev muaj zog zoo ib yam li pom lub teeb, tag nrho cov uas yog linear, tab sis lawv lub zog nkag mus tsis tshua pom. Qhov luv luv wavelength, qhov ua rau lub zog nkag mus. Sab hauv kho nrog lub teeb kis tau zoo dua. 1. Lub teeb UV tsim ib qho UV thaum tsim ib qho IR hluav taws xob cua sov. Qhov hluav taws xob kub kub no muaj txiaj ntsig zoo rau cov khoom ua haujlwm nrog qhov kub thiab txias. Nws xav tias cov nyhuv yog pom tseeb dua. Daim ntawv thov piv txwv: UV pleev xim rau cov plag tsev ntoo, cov khoom hlau, thiab lwm yam .; UV rwb thaiv tsev coatings nyob rau hauv daim ntawv Circuit Court boards; UV kua nplaum hauv cov khoom iav. 2. Qhov cuam tshuam ntawm qhov kub thiab txias yog qhov rhiab heev lossis qhov kub-resistant tshuaj lom neeg uas tsis zoo kub tsis kam. Txo IR hluav taws xob thermal yog ib qho ntawm cov ntsiab lus ntawm UV kho cov cuab yeej hauv ntau lub teb chaws hauv ntiaj teb. Feem ntau, nws yog siv rau kev siv dej txias, kev xav, kev lim dej thiab lwm yam. Kev daws, tab sis tus nqi yog lub teeb ci ultraviolet uas yuav tsum tau poob. Daim ntawv thov piv txwv: Ntau yam PVCs (xws li IC cards), yas zaj duab xis, Ke (qhov hluav taws xob) UV roj luam ntawv, ntawv tshwj xeeb luam ntawv (ice paj), lub computer keyboard luam ntawv.
