UV Absorber UV327 CAS 3864-99-1
UV-327 yog cov hmoov daj daj uas yog soluble hauv cov kuab tshuaj organic xws li methanol, ethanol, thiab toluene.Nws muaj lub siab melting point, ua rau nws haum rau cov ntawv thov uas yuav tsum tau ua hauj lwm rau siab kub.
Ib qho ntawm cov khoom tseem ceeb ntawm UV-327 yog nws lub peev xwm los nqus UV hluav taws xob hauv thaj tsam ntawm 290-400 nm.Qhov no ua rau nws muaj txiaj ntsig zoo tiv thaiv cov ntaub ntawv los ntawm kev phom sij ntawm UV teeb.UV-327 ua haujlwm los ntawm kev tshem tawm cov dawb radicals thiab cov pa oxygen reactive uas tsim los ntawm UV hluav taws xob, yog li tiv thaiv kev degradation thiab tswj lub cev ntawm cov khoom.
