Siv
Cov khoom no yog lub teeb stabilizer nrog kev ua tau zoo, muaj peev xwm nqus tau cov hluav taws xob UV ntawm 240-340 nm wavelength nrog cov yam ntxwv ntawm lub teeb xim, tsis muaj tshuaj lom, sib xws zoo, me me txav mus los, yooj yim ua thiab lwm yam. Nws tuaj yeem tiv thaiv cov polymer kom siab tshaj plaws, pab txo cov xim. Nws kuj tseem tuaj yeem ncua qhov daj thiab cuam tshuam kev 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. Ntxiv mus, nws muaj cov teebmeem zoo heev rau kev ruaj khov lub teeb rau kev ziab phenol aldehyde, varnish ntawm cawv thiab acname, polyurethane, acrylate, expoxnamee thiab lwm yam.
