Fluorescent Brightener 28 CAS 4193-55-9 yog dab tsi?

Tshuaj Fluorescent Brightener 28 yog ib yam tshuaj ua kom pom kev ci ntsa iab (OBA) uas muaj bis-triazinylaminostilbene ua haujlwm tau zoo heev. Tshuaj Optical brightener 28 nqus tau lub teeb ultraviolet (300-400 nm) thiab rov tso tawm dua li lub teeb xiav-violet fluorescence (400-500 nm), ua rau daim tawv nqaij daj thiab ua rau daim tawv nqaij dawb thiab ci ntsa iab. Tshuaj Optical Brightener 28 yog ib yam khoom siv uas siv tau zoo heev rau kev siv polymer thiab txheej txheej vim nws ruaj khov thiab sib xws nrog huab cua.
