UV327 tuaj yeem nqus tau 300-400nm ultraviolet lub teeb, tshuaj lom neeg ruaj khov, tsis muaj hluav taws xob, zoo sib xws nrog polyolefin, tsis tshua muaj suab nrov, tsis muaj tshuaj lom, tsis muaj hluav taws xob, tsis muaj corrosion, zoo cia ruaj khov, thiab kev sib koom ua ke nrog DLTDP (PS800). Nws yog tshwj xeeb tshaj yog haum rau cov polymers uas yog heev rhiab heev rau ntev wavelength ultraviolet hluav taws xob (xws li, polyimidites, polyphenyl sulfide) thiab daim ntaub ntawv uas yuav tsum tau tsis tshua muaj transmittance rau ntev wavelength ultraviolet hluav taws xob (xws li, optical lens).
Nws yog tsuas yog siv rau hauv polyvinyl chloride, polystyrene, unsaturated resin, polyurethane, polymethyl methacrylate, polyethylene, ABS resin, polypropylene fiber, xim, colouring agent, adhesives thiab lwm yam polymers thiab ntau lwm yam teb.
Ntim hauv 20 lossis 25 Kg / carton. Los yog ntim raws li cov neeg siv khoom xav tau.
Khaws rau hauv qhov chaw txias, qhuav thiab qhov cua; zam lub hnub ncaj qha.
