Yuav ua li cas siv UV teeb rau cais xim iav
1. Txoj cai ntawmUV teeb
UV teeb yog lub teeb ci nrog lub wavelength ntawm 250 ~ 400nm. Feem ntau ntawm lawv siv kev sib xyaw ua ke254nm, 300nm thiab 365nm. Qee lub sij hawm lawv kuj hu uateeb dub. Lawv feem ntau yog siv los teeb cov khoom uas yuav tsum tau kuaj xyuas. Nws lub hauv paus ntsiab lus yog tias tom qab irradiating cov khoom nrog ultraviolet rays, cov khoom yuav fluoresce, thiab cov xim fluorescent ntawm cov khoom ntawm cov khoom sib txawv kuj txawv. Los ntawm kev soj ntsuam cov fluorescence ntawm cov xim sib txawv, cov khoom ntawm cov khoom tuaj yeem raug txiav txim thawj zaug.

Nws kuj tseem yuav tsum tau txiav txim siab ua ke nrog kev ntxhib los mos ntawm txoj hlua tes thiab lwm yam ntxwv.
3. Thaum kuaj xyuas qhov tseeb ntawm lub iav kauj-toog npab, nco ntsoov ua tib zoo saib xyuas kev nyab xeeb thiab tsis txhob ncaj qha rau ntawm lub iav kauj-toog npab kom saib nws pem hauv ntej ntawm koj ob lub qhov muag. Lub kauj-toog npab yuav tsum muab tso rau hauv qhov chaw nyab xeeb thiab tom qab ntawd teeb pom kev nrog lub teeb UV kom tsis txhob raug mob qhov muag.
3. Lwm qhov chaw uas xav tau kev saib xyuas
1. Tshawb xyuas cov kab nrib pleb hauv cov iav, tshwj xeeb tshaj yog thaum muaj cov kab nrib pleb lossis kev puas tsuaj, siv lub teeb tsom teeb ultraviolet. Cov kab nrib pleb lossis kev puas tsuaj yuav pom tseeb dua. Ntawm chav kawm, qhov kev puas tsuaj rau lub khob yuav loj dua thaum lub sijhawm tshuaj xyuas.
2. Thaum siv lub teeb UV los ntsuam xyuas qhov tseeb ntawm lub iav bracelet, ua ntej kom paub tseeb tias lub teeb UV siv tau ruaj khov, txhim khu kev qha thiab tau tswj xyuas los ntawm cov kws tshaj lij.
