Benzophenone-3

Kufotokozera Kwachidule:

Benzophenone-3(UV9), yomwe nthawi zambiri imatchedwa oxybenzone m'zinthu zoteteza ku dzuwa, ndi mankhwala omwe amagwiritsidwa ntchito kwambiri mu zodzoladzola ndi zoteteza dzuwa. Fyuluta ya UV iyi imagwira ntchito ngati yotchinga dzuwa, kuyamwa ndi kutaya kuwala koopsa kwa ultraviolet (UV), makamaka UVB ndi ma radiation ena a UVA. Benzophenone-3 imateteza khungu kuti lisawotchedwe ndi dzuwa ndi kuwonongeka kwa UV, zomwe zimapangitsa kuti zikhale zogwiritsidwa ntchito pa sunscreens, mafuta odzola, ndi mankhwala opaka milomo.

    Benzophenone-3/UV-9 ndi wochita bwino kwambiri woyamwa ma radiation a UV, amatha kuyamwa bwino ma radiation a UV a 290-400 nm wavelength, koma samayamwa kuwala kowoneka bwino, makamaka kwa zinthu zowoneka bwino zowala. Ndiwokhazikika pakuwala komanso kutentha, osawola pansi pa 200 ° C, wogwiritsidwa ntchito popaka utoto ndi zinthu zosiyanasiyana zapulasitiki, makamaka zogwira mtima pa polyvinyl chloride, polystyrene, polyurethane, acrylic resin, mipando yowoneka bwino yowala, komanso zodzoladzola.

    Benzophenone-3 BP-3 UV9

    Benzophenone-3 /Oxybenzone imagwiritsidwa ntchito m'mapulasitiki ngati choyatsira kuwala kwa ultraviolet ndi stabilizer. Amagwiritsidwa ntchito, pamodzi ndi ma benzophenones ena, muzopaka dzuwa, zopopera tsitsi, ndi zodzoladzola chifukwa zimathandiza kupewa kuwonongeka kwa dzuwa. Amapezekanso, m'magulu mpaka 1%, muzitsulo za misomali.Benzophenone-3 / Oxybenzone ingagwiritsidwenso ntchito ngati photostabilizer ya resins kupanga. Benzophenones amatha kuchoka pakupanga chakudya, ndipo amagwiritsidwa ntchito kwambiri ngati zoyambitsa zithunzi zomwe zimagwiritsidwa ntchito poyambitsa mankhwala omwe amawumitsa inki mwachangu. Monga zoteteza ku dzuwa, zimapereka kuwala kwa ultraviolet, kuphatikizapo UVB ndi kuwala kwafupipafupi kwa UVA. Ndi imodzi mwazosefera za UVA zomwe zimagwiritsidwa ntchito kwambiri m'mafuta oteteza dzuwa masiku ano. Amapezekanso mu polishi ya misomali, mafuta onunkhiritsa, hairspray, ndi zodzoladzola monga photostabilizer.
