Daim ntawv thov
Octocrylene yog siv los ua cov khoom siv tshuaj pleev thaiv hnub thiab lwm yam tshuaj pleev ib ce.Nws tuaj yeem nqus tau UVA thiab UVB (nqus ntau yam 250-360nm, tuaj yeem thaiv tag nrho UVB thiab ib feem ntawm UVA), uas yog ib tiam tshiab ntawm cov tshuaj pleev thaiv hnub.
1. UV absorber: Octocrylene muaj peev xwm nqus tau UVA thiab UVB rays, thiab tuaj yeem siv rau hauv cov khoom siv tshuaj pleev thaiv hnub los pab tiv thaiv daim tawv nqaij los ntawm UV hluav taws xob.Nws tuaj yeem txo qhov kev puas tsuaj ntawm cov hluav taws xob ultraviolet rau ntawm daim tawv nqaij thiab tiv thaiv tshav ntuj, tshav pob thiab lwm yam teeb meem ntawm daim tawv nqaij uas cuam tshuam rau cov hluav taws xob ultraviolet.
2. Txhim khu kev ruaj ntseg: Octocrylene kuj tuaj yeem txhim kho kev ruaj ntseg ntawm lwm cov UV absorbers thiab txo lawv cov decomposition tus nqi nyob rau hauv tshav ntuj raug.Qhov no ua rau nws yog ib qho ntawm cov khoom xyaw nquag siv hauv cov tshuaj pleev ib ce thiab cov khoom siv hnub ci.
3. Kev mos mos: Piv nrog rau lwm cov UV absorbers, Octocrylene yog mos thiab tsis tshua muaj peev xwm ua rau tawv nqaij ua xua lossis khaus.Qhov no ua rau nws haum rau txhua hom tawv nqaij, nrog rau cov tawv nqaij rhiab heev.
