2 - hydroxy {4 4}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} {} {} { Nws yog qhov tshwj xeeb hauv kev nqus UVB rays, pab tiv thaiv kev tshav ntuj, kev ua kom tawv nqaij puas tsuaj. Nws cov dej solubility ua rau nws haum rau kev koom tes rau hauv cov tshuaj pleev, cov yeeb yaj kiab, cov kua txiv, thiab lwm yam aqueous raws li cov qauv. Tshaj Plastics, nws tseem ua haujlwm hauv cov plastics, cov ntaub ntawv ntim khoom kom tiv thaiv UV degradation, discoloration, thiab poob ntawm cov khoom siv neeg kho mob hauv cov khoom siv polymeric raug rau hnub ci. Nws cov tshuaj ruaj khov ua kom muaj kev tiv thaiv UV ntev ntev hauv ob qho tib si kev siv tshuaj pleev thiab kev lag luam.
Cov txiaj ntsig
Cov txiaj ntsig ntawm cov compise no tshwm sim los ntawm nws tau zoo UV nqus, dej solubility, thiab photostability. Nws cov kev nqus Uvb muaj zog pab tiv thaiv cov tawv nqaij los ntawm kev phom sij, txo qis kev pheej hmoo ntawm kev tshav ntuj, ua kom muaj kev puas tsuaj DNA. Cov dej solubility tso cai rau cov neeg ua haujlwm los tsim cov pob tshab thiab tsis-}}}}}}} Nws cov photostability kom ntseeg tau tias nws khaws UV - lim kev ua tau zoo thaum lub hnub caij nyoog ntev, txhim kho cov khoom lag luam ruaj khov. Ib qho ntxiv, nws tau sib haum nrog lwm cov neeg lim dej ov thiab pleev xim, ua kom muaj kev txhim kho ntawm cov qauv hluav taws xob uas tiv thaiv kev tiv thaiv ob qho tib si UVA thiab UVB. Nws txoj kev nyab xeeb thiab kev ua tau zoo profile ua rau nws muaj kev ntseeg siab thiab pom UV lim hauv tus kheej thiab kev siv luam ntawv.
