Daim Ntawv Thov
Benzophenone-4 yog ib yam khoom uas yaj tau hauv dej & pom zoo kom siv rau cov yam ntxwv tiv thaiv hnub ci siab tshaj plaws. Kev sim tau qhia tias Benzophenone-4 ua kom cov gels ruaj khov raws li polyacrylic acid (Carbopol, Pemulen) thaum lawv raug rau UV hluav taws xob. Qhov concentration qis li 0.1% muab cov txiaj ntsig zoo. Nws yog siv ua ultra-violet stabilizer hauv cov plaub mos, tshuaj pleev ib ce, tshuaj tua kab & lithographic phaj txheej. Nws yuav tsum tau sau tseg.
tias Benzophenone-4 tsis sib haum nrog Mg ntsev, tshwj xeeb tshaj yog nyob rau hauv dej-roj emulsions. Benzophenone-4 muaj xim daj uas dhau los ua ntau dua nyob rau hauv alkaline ntau yam & tej zaum yuav hloov pauv qhov sib txawv ntawm cov xim daws teeb meem.
