UV-531 yog dab tsi?
UV-531 (2-Hydroxy-}4-n-octoxybenzophenone) yog ib qho zoo heev benzophenone-hom ultraviolet absorber tsim los tiv thaiv polymers thiab coatings los ntawm UV-induced degradation.
Nws muaj zog absorbs ultraviolet lub teeb nyob rau hauv 260-350 nm ntau yam, pab tiv thaiv yellowing, tawg, tsis muaj zog, thiab aging tshwm sim los ntawm ntev - UV raug.
UV-531 yog dav siv thoob plaws hauv kev lag luam xws li yas, txheej, roj hmab, nplaum, thiab petrochemicals, ua rau nws muaj ntau yam thiab muaj txiaj ntsig UV stabilizer.
Solubility
Soluble nyob rau hauv acetone, benzene, n-heptane, thiab n-hexane; me ntsis soluble hauv methanol thiab ethanol.
