Daim Ntawv Thov

UV-144 ua haujlwm siab NOR hom hindered amine lub teeb stabilizer, tsim rau kev lag luam hmoov txheej. Hindered amine stabilizers nrog ib feem hindered phenolic antioxidant tus cwj pwm tuaj yeem txo qhov tawg thiab poob ntawm gloss, ntev lub neej kev pabcuam ntawm cov xim zaj duab xis. Tib lub sijhawm, nws muaj cov yam ntxwv ntawm kev ua kom cov hmoov txheej frictional thiab charged, txhim kho qhov ceev ntawm cov hmoov txheej. Nws yog siv rau hauv hmoov txheej, coil steel, automotive coatings, thiab lwm yam.
