UV327 tuaj yeem muaj kev nqus 300-400nm ultraviolet lub teeb, tsis muaj zog, tsis muaj kuab, thiab muaj kev cia siab, thiab muaj txiaj ntsig zoo, thiab tseem ceeb synergino nrog dltdp (PS200). Nws yog qhov tsim nyog tshwj xeeb rau cov polymers uas muaj kev nkag siab ntev heev rau ntev ntxiv mus rau ntev nthwv dej Ultiat (piv txwv li, kho qhov muag).
Nws yog tsuas yog siv nyob rau hauv polyvinyl chloride, polystyrene, polyethylene, polyenethane fiber ntau, pleev xim rau tus neeg sawv cev, cov nplaum thiab lwm thaj chaw.
Ntim hauv 20 lossis 25 kg / thawv. Lossis ntim raws li cov neeg yuav tsum tau ua.
Khaws rau hauv qhov chaw txias, qhuav thiab muaj qhov chaw siv; Zam kev tshav ntuj ncaj qha.
