Iyini i-UV-144 CAS 63843-89-0?

Impuphu emhlophe kuya kophuzi kancane ye-UV-144, uhlobo lwe-NOR olusebenza kahle kakhulu luvimbele isiqinisi sokukhanya kwe-amine, esifanelekile embonini yokumboza ngempuphu. Iziqinisi ze-amine ezivinjiwe ezinokuziphatha kwe-phenolic antioxidant okuvinjiwe kancane zinganciphisa ukuqhekeka nokulahlekelwa ukukhanya, zandise kakhulu impilo yenkonzo yamafilimu opende.

Isicelo

Uhlobo lwe-UV-144 olusebenza kahle kakhulu lwe-NOR luvimbele isiqinisi sokukhanya kwe-amine, olufanele imboni yokugqoka i-powder. Iziqinisi ze-amine ezivinjiwe ezinokuziphatha kwe-phenolic antioxidant okuvinjiwe kancane zinganciphisa ukuqhekeka nokulahlekelwa ukukhanya, zandise kakhulu impilo yenkonzo yamafilimu opende. Ngesikhathi esifanayo, inempahla yokwenza izembozo ze-powder zibe nokungqubuzana nokushaja, okuthuthukisa izinga lokugqoka i-powder. Isetshenziswa kakhulu ezimbozweni ze-powder, insimbi ye-coil, izembozo zezimoto, njll.
