Puas yog IFAN PPR kav UV tiv taus?
Nov 17, 2023
UV tsis kam ntawm IFAN PPR kav yog ib qho tseem ceeb rau kev txiav txim siab, tshwj xeeb tshaj yog rau cov ntawv thov uas cov kav dej raug tshav ntuj. PPR (Polypropylene Random Copolymer), cov khoom siv hauv IFAN PPR kav, inherently muaj qee qhov kev tiv thaiv UV. Txawm li cas los xij, kev raug UV hluav taws xob ntev ntev tseem tuaj yeem cuam tshuam cov khoom siv lub sijhawm, ua rau degradation.
Txhawm rau txhim kho UV tiv thaiv, cov tuam txhab xws li IFAN tuaj yeem ntxiv UV stabilizers rau cov khoom siv PPR thaum lub sijhawm tsim khoom. Cov stabilizers no pab tiv thaiv cov kav dej tiv thaiv cov teeb meem UV rays, ua kom lawv lub neej ntev thiab tswj lawv txoj kev ncaj ncees thaum siv nyob rau sab nraum zoov lossis thaj chaw uas muaj hnub ci tseem ceeb.
Ntxiv mus, nyob rau hauv daim ntawv thov uas raug UV yog ib qho kev txhawj xeeb, kev tiv thaiv ntxiv tuaj yeem ua tau, xws li siv cov yeeb nkab npog sab nraud lossis pleev xim rau cov kav dej nrog cov xim UV-resistant. Cov kev coj ua zoo li no tiv thaiv cov kav dej los ntawm UV puas.
Hauv cov ntsiab lus, thaum IFAN PPR cov kav dej tuaj yeem muaj qhov cuam tshuam los ntawm UV vim qhov xwm txheej ntawm PPR, ntxiv UV stabilizers thiab kev tiv thaiv kev tiv thaiv yuav raug siv los xyuas kom meej lawv cov kav ntev thiab ntev nyob rau hauv ib puag ncig nrog UV raug siab. Rau cov ntsiab lus tshwj xeeb hais txog UV tsis kam ntawm IFAN PPR kav, sab laj nrog cov chaw tsim khoom tshwj xeeb lossis cov ntaub ntawv kev tshaj lij yuav muab cov ntaub ntawv raug thiab ntxaws.
