Benzophenone-3
Benzophenone-3/UV-9 ke sesebelisoa se sebetsang hantle haholo se monyang mahlaseli a UV, se khonang ho monya mahlaseli a UV a 290-400 nm wavelength, empa se batla se sa monye khanya e bonahalang, haholo-holo lihlahisoa tse bonaletsang tse mebala e khanyang. E tsitsitse ho khanya le mocheso, ha e senyehe ka tlase ho 200 ° C, e sebetsa ho pente le lihlahisoa tse fapaneng tsa polasetiki, haholo-holo tse sebetsang hantle ho polyvinyl chloride, polystyrene, polyurethane, resin ea acrylic, thepa ea ka tlung e bonaletsang ea 'mala o bobebe, hammoho le litlolo.
Benzophenone-3 /Oxybenzone e sebelisoa ka li-plastiki e le ntho e monyang lebone la ultraviolet le stabilizer. E sebelisoa, hammoho le li-benzophenone tse ling, litlolong tse sireletsang letlalo letsatsing, li-sprays tsa moriri le litlolo hobane li thusa ho thibela tšenyo e ka bang teng ka lebaka la khanya ea letsatsi. E boetse e fumanoa, ka ho tsepamisa mohopolo ho fihlela ho 1%, ka lipekere tsa lipekere.Benzophenone-3 / Oxybenzone e ka boela ea sebelisoa e le photostabilizer bakeng sa li-resin tsa maiketsetso. Li-benzophenones li ka tsoa ka har'a liphutheloana tsa lijo, 'me li sebelisoa haholo e le li-photo-initiators tse sebelisoang ho qala k'hemik'hale e omisang enke kapele. Joaloka setlolo se sireletsang letsatsi, se fana ka tšireletso ea ultraviolet e pharaletseng, ho akarelletsa le UVB le mahlaseli a maqhubu a makhutšoane a UVA. Ke e 'ngoe ea li-filters tsa UVA tse sebelisoang haholo ka har'a li-sunscreens kajeno. E boetse e fumanoa ho polish ea manala, litlolo tse nkhang hamonate, sesepa sa moriri, le litlolong e le mokhoa oa ho etsa photostabilizer.
