(1) Cov khoom ci. Thaum cov ntaub ntawv luam tawm nkhaus, UV ntawv luam tawm tsis tuaj yeem luam tawm. Yog tias cov khoom siv kos, nws muaj peev xwm hais tias cov qauv luam tsis meej vim hais tias qhov kev ncua deb ntawm lub taub hau thiab cov khoom yog nyob deb dhau. Yog hais tias lub hau thiab qhov khoom nrug deb dhau lawm, tej zaum yuav ua rau lub tshuab no tsoo cov khoom, thiab ua rau lub taub yas qis.
(2) Cov khoom txig cov ntaub ntawv. Thaum peb sau cov ntaub ntawv muaj zog, xws li tsom iav, thiab lwm yam, vim hais tias qhov teeb ntawm UV teeb ntawm cov khoom, cov khoom yuav tsum muaj kev cuam tshuam, kom ib feem ntawm lub teeb reflected rov qab rau lub nozzle, kom lub khawm sab hauv lub qhov rooj yuav ua kom muaj zog, ua rau lub taub hau nrawm.
(3) Tom qab luam ntawv, cov ntaub ntawv xav tau kub, kev kho acid ntau. Xees ntawv ntawm UV luam ntawv yuav ua rau cov qauv poob, deformation thiab lwm yam teeb meem tom qab kub siab, muaj zog acid kho.
