Dab tsi yog qhov laj thawj tseem ceeb ntawm kev siv LED curing adhesives tshaj UV curable adhesives?
LED curing adhesives feem ntau kho nyob rau hauv 30-45 vib nas this nyob rau hauv lub teeb qhov chaw ntawm 405 nanometer (nm) wavelength. Ib txwm siv lub teeb kho cov nplaum, los ntawm qhov sib txawv, kho nyob rau hauv ultraviolet (UV) lub teeb qhov chaw nrog wavelengths ntawm 320 thiab 380 nm. Rau cov kws tsim qauv tsim, lub peev xwm los kho cov nplaum nplaum hauv qab lub teeb pom kev qhib ntau yam kev sib txuas, encapsulation thiab sealing daim ntaub ntawv uas yav tas los tsis haum rau cov khoom kho lub teeb, vim nyob rau hauv ntau daim ntawv thov cov substrates yuav tsis kis nyob rau hauv lub UV wavelength tab sis tso cai rau pom. Lub teeb kis tau tus mob.
Dab tsi yog qee yam uas yuav cuam tshuam rau lub sijhawm kho?
Feem ntau, lub teeb ci ntawm LED teeb yuav tsum nyob nruab nrab ntawm 1 thiab 4 watts / cm2. Lwm qhov kev txiav txim siab yog qhov kev ncua deb ntawm lub teeb mus rau txheej nplaum, piv txwv li, qhov txuas ntxiv ntawm lub teeb ntawm cov nplaum, lub sijhawm kho tau ntev dua. Lwm yam yuav tsum tau coj mus rau hauv tus account yog lub thickness ntawm cov nplaum txheej, ib txheej nyias nyias yuav kho sai dua li cov txheej tuab, thiab pob tshab ntawm cov substrates yog li cas. Cov txheej txheem yuav tsum tau tweaked kom optimize lub sij hawm kho, raws li tsis tau tsuas yog nyob rau hauv lub geometries ntawm txhua tus tsim, tab sis kuj yog hom khoom siv.
Koj ua li cas kom ntseeg tau tias LED nplaum tau kho tag nrho?
Thaum cov nplaum LED tau kho tag nrho, nws tsim ib qho nyuaj thiab tsis-tacky nto uas yog iav du. Qhov teeb meem nrog kev siv zog ua ntej los kho ntawm qhov ntev wavelength yog ib qho mob hu ua oxygen inhibition. Oxygen inhibition tshwm sim thaum atmospheric oxygen curbs cov txheej txheem dawb-radical polymerization uas kho yuav luag tag nrho cov nplaum UV. Nws ua rau tacky, ib nrab kho qhov chaw.
