Cov qauv molecular ntawmCov khoom nqus UVfeem ntau muaj cov sib txuas ob npaug lossis cov nplhaib aromatic, uas tuaj yeem nqus cov duab ultraviolet ntawm cov wavelengths tshwj xeeb (feem ntau UVA thiab UVB).

Thaum cov duab hluav taws xob ultraviolet ua rau cov molecules nqus tau, cov electrons hauv cov molecules hloov pauv ntawm lub xeev av mus rau lub xeev zoo siab, nqus cov zog ntawm cov duab hluav taws xob ultraviolet.

Tom qab nqus tau lub teeb ultraviolet, lub molecule nyob rau hauv lub xeev zoo siab nrog lub zog siab. Yuav kom rov qab mus rau lub xeev ruaj khov, cov molecule nqus tau yuav tso tawm lub zog hauv qab no:
①Kev hloov pauv tsis yog hluav taws xob: hloov lub zog mus rau hauv lub zog cua sov thiab tso tawm mus rau ib puag ncig.
②Fluorescence lossis phosphorescence: ib feem ntawm lub zog yuav raug tso tawm hauv daim ntawv ntawm lub teeb pom kev (tsis tshua muaj).

Los ntawm kev nqus cov teeb ci ultraviolet thiab hloov lawv mus ua lub zog cua sov, cov khoom nqus UV txo qhov kev puas tsuaj ncaj qha ntawm cov teeb ci ultraviolet rau cov ntaub ntawv (xws li plastics, coatings) lossis daim tawv nqaij.
Hauv cov khoom siv tiv thaiv hnub, cov khoom nqus UV tuaj yeem tiv thaiv cov duab UV kom tsis txhob nkag mus rau hauv daim tawv nqaij thiab txo qhov kev pheej hmoo ntawm kev kub hnyiab, kev laus ntawm daim duab thiab mob qog nqaij hlav.

Peb liCov khoom nqus UVyog tsim rau cov polymers, coatings thiab tshuaj pleev ib ce. Yog tias koj xav tau cov khoom, thov koj xav tiv tauj peb, peb yuav teb koj tsis pub dhau 48 teev.
