[UV LED Lub Teeb Siv Tau] UV LED Chaw Tsim Tshuaj Qhia Koj Txog Cov

Hauv kev siv tiag tiag ntawm cov neeg siv khoom, cov teeb meem no feem ntau tshwm sim, uas yog, kuv tsis paub yog tias qhov kev siv hluav taws xob ntawm nws tus kheej UV kho tshuab yog tsim nyog. Niaj hnub no, Tianhui yuav tham txog lub ntsiab tseem ceeb uas cuam tshuam rau irradiation ntawm UVLED txias lub teeb qhov chaw kho tshuab. KHAUJ THAWK I. Cov yam ntxwv ntawm cov yam ntxwv ntawm UVLED txias lub teeb qhov chaw kho tshuab los ntawm UVLED solidification khoom, txiav txim siab nkag mus rau hauv cov khoom kho tau tawm los ntawm lub teeb kom ua rau lub teeb thiab ua rau cov molecules. UV solidification txiav txim siab kev sib tsoo ntawm photons thiab molecules, uas tuaj yeem ua rau cov molecules kis tusyees los ntawm cov ntaub ntawv. Ntxiv nrog rau cov yam ntxwv ntawm UVLED lub teeb qhov chaw, cov bears solidified kuj muaj cov yam ntxwv kho qhov muag thiab thermodynamic. Lawv cuam tshuam nrog hluav taws xob hluav taws xob thiab muaj kev cuam tshuam loj rau cov txheej txheem ntawm solidifying. UVLED's spectral spectral ob, spectral absorption, lub teeb lub zog yog tus npaum li cas ntawm tus number case absorbed rau hauv lub wavelength nyob rau hauv lub maj nce thickness. Lub zog ntau absorbed nyob ze ntawm qhov chaw, lub zog tsawg tau txais. Txawm li cas los xij, nrog rau qhov sib txawv wavelengths, qhov ntev ntawm lub wavelength, ntau qhov kev nkag mus tau zoo, qhov luv dua lub wavelength, thiab qhov tsawg dua qhov nkag mus. Hais txog cov txheej txheem tsim khoom tiag tiag, 365nm wavelength UVLED ultraviolet rays Nws zoo dua rau cov saib, thiab qhov ntev wavelength lossis 405nm nkag mus zoo dua 365nm. Tag nrho cov spectral absorption tus nqi suav nrog tag nrho los ntawm kev cuam tshuam ntawm lub teeb ua rau, ib qho tshuaj molecular, pawg thiab additives nrog rau cov pigments. Thib peb, qhov kev xav thiab tawg yog qhov txheeb ze thiab nqus tau. Lub teeb tuaj yeem hloov pauv los ntawm kev coj tus cwj mem, uas ua rau muaj kev cuam tshuam thiab tawg. Cov yam tseem ceeb no tau txo lub zog mus txog qhov sib sib zog nqus UV zog, tab sis txhim kho cov kev ua tau zoo ntawm cov tshuaj tiv thaiv. Qhov hloov nkhaus ntawm UVLED kub thiab wavelength 4. Qhov kub ntawm lub tshuab ua kom txias UVLED curing tshuab muaj qhov cuam tshuam loj rau tus nqi kho cov tshuaj tiv thaiv (uas yog, lub teeb muaj zog irradiation). Ib qho kev txwv tseem ceeb uas cuam tshuam rau cov txheej txheem kho. Cov neeg uas paub cov yam ntxwv ntawm qhov kub thiab txias ntawm UV LED teeb hlaws yuav tsum paub tias qhov kub thiab txias, qhov wavelength ntawm UV LED yuav ntau dua. Piv txwv li, qee lub teeb hlaws hauv tsev, thaum lawv thawj zaug siv, cov nyhuv solidification yog qhov zoo. Muaj ib sijhawm. Tom qab ntawd, raws li qhov kub thiab txias, lub wavelength ntawm UVLED teeb hlaws tau hloov. 365nm yuav drift nyob rau hauv kev coj ntawm 370/380nm. Tsis muaj txoj hauv kev los nqus cov kua nplaum los yog tus cwj mem ntawm qhov ua rau, thiab ib txwm tsis tuaj yeem ua tiav tus ntoo khaub lig-txuas kev txhais lus ntawm cov kua nplaum los yog tus cwj mem molecules, qhia txog qhov kev xav ntawm macro, uas yog, cov kua nplaum thiab tus number case tsis zoo-kho lossis tsis muaj solidification. . Tianhui tau ua haujlwm ntau tshaj kaum xyoo rau ntau yam kev lag luam. Yog tias koj muaj lus nug txog UVLED curing, thov hu rau peb txhua lub sijhawm!
