Daim ntawv thov

Cov khoom no yog lub teeb stabilizer nrog kev ua haujlwm zoo, muaj peev xwm nqus tau UV
hluav taws xob ntawm 240-340 nm wavelength nrog cov yam ntxwv ntawm lub teeb xim, tsis muaj tshuaj lom, zoo compatibility, me zog, yooj yim ua thiab lwm yam. Nws tuaj yeem tiv thaiv cov polymer rau nws qhov siab tshaj plaws, pab txo cov xim. Nws tseem tuaj yeem ncua qhov yellowing thiab cuam tshuam qhov poob ntawm nws lub cev ua haujlwm. Nws yog dav siv rau PE, PVC, PP, PS, PC organic iav, polypropylene fiber, ethylene-vinyl acetate thiab lwm yam. Tsis tas li ntawd, nws muaj lub teeb ruaj khov zoo heev rau ziab phenol aldehyde, kua roj vanish ntawm cawv thiab acname, polyurethane, acrylate. , exox npe
