Iyini i-UV Absorber BP2 CAS 131-55-5?

I-2, 2 ', 4, 4 '-tetrahydroxybenzophenone iyisithambisi se-ultraviolet esisebenza kahle kakhulu esincibilika emanzini, esiyingxenye yemikhiqizo yochungechunge lwe-benzophenone ultraviolet absorber. I-2, 2 ', 4, 4 '-tetrahydroxybenzophenone iyasha, futhi ukusha kukhiqiza umusi we-nitrogen oxide onobuthi.

Isicelo

Njengamanje, i-2, 2 ', 4, 4'-tetrahydroxybenzophenone isetshenziswa kabanzi kumapulasitiki, ama-resin, izembozo, irabha yokwenziwa kanye neminye imikhakha, i-2, 2', 4, 4 '-tetrahydroxybenzophenone isetshenziswa njengezinto zokwelapha ezihlanganisa imithi, izinto ezithinta ukukhanya, izithasiselo ezilwa ne-ultraviolet ezimonyweni nokunye. Eminyakeni yamuva nje, ukusetshenziswa kwezindwangu kuye kwanakwa yimboni yezindwangu, futhi ububanzi buyanda.
