Polypropylene thiab polyester fabrics yog ob qho tib si cov ntaub ntawv uas feem ntau siv hauv cov khoom siv dej tsis zoo. Txawm li cas los xij, lawv cov ntawv thov txawv me ntsis.
Ua ntej, polypropylene ntaub yog tsim los ntawm polypropylene fibers thiab muaj kev puas tsuaj thiab kub ua hauj. Yog li ntawd, nws yog feem ntau xaiv rau waterproofing membranes qhov twg cov kev xav tau tshwj xeeb yog siab.
Polyester ntaub, ntawm qhov tod tes, yog tsim los ntawm polyester fibers thiab muaj kev yooj yim heev thiab huab cua tsis kam, ua rau nws tsim nyog rau cov ntawv thov uas cov kev xav tau siab.
Tsis tas li ntawd, polypropylene ntaub feem ntau muaj kev tiv thaiv UV zoo heev, tiv thaiv UV hluav taws xob zoo, ua rau nws tsim nyog rau kev siv sab nraum zoov.
Feem ntau, kev xaiv ntawm polypropylene thiab polyester fabrics rau waterproofing membranes nyob ntawm tej daim ntawv thov thiab yuav tsum tau. Peb tuaj yeem xaiv cov ntaub ntawv sib txawv raws li peb cov kev xav tau los xyuas kom meej qhov kev ua tau zoo thiab kev ua haujlwm ntev ntawm cov khoom siv dej tsis zoo.
