Yintoni i-Light Stabilizer-944 CAS 70624-18-9?

I-stabilizer yokukhanya i-UV-944 inokumelana nokukhupha okulungileyo, okufanelekileyo ngokukhethekileyo kwiimveliso ezincinci, ezinjengeefayili kunye neefilimu; Isenokuphucula ukuchasana nokuguga kwe-oksijini ye-thermal yezinto. I-Standabilizer yokukhanya i-HS-944 imhlophe ukuya kwiincinci eziphuzi ezikhanyayo okanye i-powder, i-melting point 100-135 ° C, ubunzima be-molecular 2000-3100, kunye nokuhambelana okugqwesileyo, ukuxhathisa ukukhutshwa kunye nokuguquguquka okuphantsi. Ekubeni i-UV-944 iyisilinganisi esiphezulu se-molecular mass stabilizer, kwaye i-molecule iqulethe kuphela inani elikhulu le-methylate, lizinzile xa liphathwa nge-oksijini eshushu.
