UV curing yog ib txoj hauv kev uas raug ultraviolet teeb ua rau kua los yog film kom kho tau. Thaum lub sij hawm tua, cov tshuaj lom neeg siv tshuaj tuaj thiab ua rau daim ntawv kawg. UV curing yog siv rau ntau hom khoom ntawm cov khoom xws li cov khoom siv, cov tshuaj, cov tshuaj, thiab coatings. Cov lag luam uas tsim cov khoom siv los kho hauv UV teeb kuj tseem muag cov khoom siv los siv UV kho xws li cov rooj sib txuas teeb thiab lub teeb qij.
Muaj ntau ntau txoj hauv kev uas txoj kev ua kom muaj peev xwm ua tau haujlwm. Txhua tus koom tes qee cov tshuaj lom neeg cov tshuaj tiv thaiv uas yog chiv los ntawm lub teeb nyob rau hauv cheeb tsam ultraviolet ntawm cov spectrum. Hauv chav kawm, qhov no yog ua tiav nrog cov khoom siv thiab dab tsi yog hu ua photoinitiator, ib qho tshuaj uas yuav pib qhov tshuaj tiv thaiv thaum nws pom teeb. Nyob rau hauv rooj plaub ntawm ib yam khoom tsim rau UV tua, tus yees duab tsuas yog ua haujlwm thaum nws pom UV teeb.
Qhov kev tshav ntuj ntawm qhov teeb meem feem ntau tseem ceeb heev. Ntau cov khoom uas tsim los kho kom zoo thaum lub teeb ntawm 200 thiab 400 nanometers, los yog UVA, UVB, thiab UVC lub teeb. Cov khoom feem ntau qhia tias qhov siv thiab qhov ntev yuav tsum tau kho kom cov neeg siv cov khoom tsim nyog. Yog tsis siv cov cuab yeej zoo yuav ua rau muaj kev tsis zoo uas ua rau lub cev tsis zoo, tawg, ua kom tsis muaj zog, thiab lwm yam teeb meem.
Ib qho loj zoo rau UV kho yog tias nws tsim tau los ua haujlwm sai heev, muab kev kho sai sai kom cov kab sib dhos tsis muaj nrog nrog tos kom tua kom tiav. Tsis tas li ntawd xwb, tib neeg tuaj yeem ua haujlwm thaum lawv caij nyoog nrog cov ntaub ntawv tsis tuaj yeem, vim tias nws yuav tsis kho nyob rau hauv chav teeb.

Yam yuav tsum paub txog thaum ua haujlwm nrog lub tshuab ultraviolet yog tias txawm hais tias lub teeb tsis pom, nws tuaj yeem ua rau lub qhov muag puas tsuaj. Cov neeg yuav tsum hnav qhov muag tiv thaiv thiab yuav tsum tsis txhob thaj tsam, yog tias ua tau, thaum lub teeb muaj nyob. Feem ntau cov ultraviolet teeb ua emit ib co pom lub teeb, uas muaj peev xwm ua haujlwm ceeb toom neeg ceeb toom rau qhov tseeb tias lub teeb muaj nyob. Nws yog ib qho tseem ceeb uas cov kws kho mob thiab cov neeg ua haujlwm hauv lub tsev laus paub txog kev tsim kev puas tsuaj ntawm UV ntau heev kom lawv muaj peev xwm siv tau ceev faj.
