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

I-UV-144 emhlophe ukuya kumpushana ophuzi kancane, ukusebenza okuphezulu NOR uhlobo oluvimbe isizinzi sokukhanya kwe-amine, esifanele imboni yokumboza impushana. Iziqinisi ze-amine ezivinjiwe ezinokuziphatha okuvimbelwe ngokwengxenye kwe-phenolic antioxidant kunganciphisa ukuqhekeka nokulahlekelwa isicwebezelisi, kwandise kakhulu impilo yesevisi yamafilimu kapende.

Isicelo

Ukusebenza okuphezulu kwe-UV-144 uhlobo lwe-NOR luvimbele isizinzi sokukhanya se-amine, esilungele imboni yokumboza impushana. Iziqinisi ze-amine ezivinjiwe ezinokuziphatha okuvimbelwe ngokwengxenye kwe-phenolic antioxidant kunganciphisa ukuqhekeka nokulahlekelwa isicwebezelisi, kwandise kakhulu impilo yesevisi yamafilimu kapende. Ngesikhathi esifanayo, inendawo yokwenza i-powder coatings i-frictional futhi ikhokhiswe, ithuthukisa izinga lokugqoka i-powder. Isetshenziswa kakhulu kuma-powder coatings, insimbi yekhoyili, i-automotive coatings, njll.
