Daim ntawv thov

Benzophenone muaj kev siv ntau yam xws li kev lag luam tshuaj, tshuaj thiab tshuaj pleev ib ce. Hauv kev lag luam chemical nws yog siv los ua photoinitiator rau ultraviolet curing ntawm polymerization cov tshuaj tiv thaiv. Qhov no tso cai rau cov txheej txheem polymerization mus sai dua nyob rau hauv kev cuam tshuam ntawm ultraviolet hluav taws xob. Tsis tas li ntawd, nws ua raws li tus neeg sawv cev sib txuas uas pab txhawb cov khoom kawg.
Hauv cov khoom siv tshuaj pleev ib ce, benzophenone ua haujlwm ua lub teeb ci ultraviolet vim nws pab tiv thaiv daim tawv nqaij los ntawm teeb meem UV rays. Nws tuaj yeem pom nyob rau hauv cov tshuaj pleev thaiv hnub, di ncauj balms thiab ntsej muag cream.
Nws kuj yog siv nyob rau hauv ntau lwm yam kev siv xws li analytical chemistry, inks thiab dyes. Nws yog siv los ua tus qauv siv cov khoom siv rau kev ntsuas cov ntsuas ntsuas hauv cov chaw soj ntsuam.
