Benzophenone-3
Benzophenone-3/UV-9 yog ib tug high-efficienct UV hluav taws xob absorbing tus neeg saib xyuas, muaj peev xwm ntawm zoo absorbing UV hluav taws xob ntawm 290-400 nm wavelength, tab sis nws yuav luag tsis nqus pom lub teeb, tshwj xeeb tshaj yog muaj feem xyuam rau lub teeb xim pob tshab khoom. Nws yog qhov ruaj khov rau lub teeb thiab cua sov, tsis decomposable hauv qab 200 ° C, muaj feem xyuam rau cov xim thiab ntau yam khoom yas, tshwj xeeb tshaj yog rau polyvinyl chloirde, polystyrene, polyurethane, acrylic resin, lub teeb xim pob tshab rooj tog, nrog rau cov tshuaj pleev ib ce.
Benzophenone-3 / Oxybenzone yog siv rau hauv cov yas ua ib qho ultraviolet lub teeb absorber thiab stabilizer. Nws yog siv, nrog rau lwm yam benzophenones, hauv cov tshuaj pleev thaiv hnub, tshuaj pleev plaub hau, thiab tshuaj pleev ib ce vim tias lawv pab tiv thaiv kev puas tsuaj los ntawm tshav ntuj raug. Nws kuj tseem pom, nyob rau hauv ntau txog 1%, nyob rau hauv cov ntsia thawv polishes.Benzophenone-3 / Oxybenzone kuj siv tau los ua ib tug photostabilizer rau hluavtaws resins. Benzophenones tuaj yeem tawm los ntawm cov ntim khoom noj, thiab tau siv dav los ua cov duab-pib siv los pib cov tshuaj uas ua kom cov number case qhuav sai dua. Raws li cov tshuaj pleev thaiv hnub, nws muab dav-spectrum ultraviolet kev pab them nqi, suav nrog UVB thiab luv-yoj UVA rays. Nws yog ib qho ntawm feem ntau siv cov organic UVA lim hauv cov tshuaj pleev thaiv hnub hnub no. Nws kuj muaj nyob rau hauv cov ntsia thawv polish, fragrances, hairspray, thiab tshuaj pleev ib ce raws li ib tug photostabilizer.
