Cov txiaj ntsig ntawm UV / LED Curing Adhesives

Vim li cas ho siv cov nplaum LED curing dua li cov nplaum UV curable?

Cov nplaum LED kho feem ntau yuav kho tau hauv 30-45 vib nas this hauv qab lub teeb ntawm 405 nanometer (nm) wavelength. Cov nplaum kho lub teeb ib txwm muaj, los ntawm kev sib piv, kho tau hauv qab lub teeb ultraviolet (UV) nrog wavelengths ntawm 320 thiab 380 nm. Rau cov kws tsim qauv, lub peev xwm los kho cov nplaum tag nrho hauv qab lub teeb pom kev qhib ntau yam kev sib txuas, encapsulation thiab sealing daim ntawv thov uas yav dhau los tsis haum rau cov khoom kho lub teeb, vim tias hauv ntau daim ntawv thov cov substrates yuav tsis xa hauv UV wavelength tab sis tso cai rau lub teeb pom kev kis tau.

Muaj tej yam dab tsi uas yuav cuam tshuam rau lub sijhawm kho mob?

Feem ntau, lub zog ntawm lub teeb LED yuav tsum nyob nruab nrab ntawm 1 thiab 4 watts/cm2. Lwm qhov kev xav txog yog qhov deb ntawm lub teeb mus rau txheej nplaum, piv txwv li, qhov deb ntawm lub teeb ntawm cov nplaum, lub sijhawm kho ntev dua. Lwm yam uas yuav tsum tau coj mus rau hauv tus account yog qhov tuab ntawm txheej nplaum, ib txheej nyias dua yuav kho sai dua li ib txheej tuab dua, thiab qhov pob tshab ntawm cov substrates. Cov txheej txheem yuav tsum tau tweaked kom zoo tshaj plaws lub sijhawm kho, tsis yog raws li geometries ntawm txhua tus qauv tsim, tab sis kuj yog hom khoom siv siv.

Koj yuav ua li cas kom paub tseeb tias cov nplaum LED tau kho tag nrho?

Thaum cov nplaum LED kho tag, nws tsim ib qho chaw tawv thiab tsis nplaum uas yog iav du. Qhov teeb meem nrog kev siv zog ua ntej los kho ntawm qhov ntev dua yog ib qho mob hu ua oxygen inhibition. Oxygen inhibition tshwm sim thaum cov pa oxygen hauv huab cua txwv tsis pub cov txheej txheem polymerization dawb-radical uas kho yuav luag txhua cov nplaum UV. Nws ua rau muaj qhov chaw nplaum, kho ib nrab.

Kev txwv tsis pub siv oxygen yog qhov pom tseeb tshaj plaws hauv cov ntawv thov uas tsis muaj kev thaiv rau cov pa oxygen hauv huab cua. Piv txwv li, kev txwv tsis pub siv oxygen yuav phem dua hauv daim ntawv thov txheej conformal nrog kev kho qhib-cua dua li nws yuav yog hauv daim ntawv thov uas muab cov nplaum rau ntawm cov txheej iav.

Cov txiaj ntsig kev nyab xeeb ntawm cov nplaum LED kho piv rau UV kho yog dab tsi?

Cov teeb UV yuav ua rau muaj teeb meem kev nyab xeeb vim tias lawv muaj peev xwm ua rau tawv nqaij kub hnyiab thiab raug mob qhov muag; txawm hais tias cov teeb LED tseem yuav tsum tau siv nrog cov khoom siv tiv thaiv tus kheej kom zoo, lawv feem ntau tsis ua rau muaj kev pheej hmoo zoo ib yam li lawv cov UV kho.

Master Bond muab cov txheej txheem tshwj xeeb twg uas kho tau nrog lub teeb LED?

Master Bond LED 400 series muaj ntau yam khoom siv engineering uas xav tau thiab nyob ntawm qib, siv tau rau kev sib txuas, encapsulation, thiab txheej. Cov khoom tshiab tshaj plaws hauv cov koob yog LED405Med.
