Dej thaiv yog qhov tseem ceeb rau ntau cov ntawv thov cable, tshwj xeeb yog siv nyob rau hauv ib puag ncig. Lub hom phiaj dej thaiv yog txhawm rau tiv thaiv cov dej los ntawm kev nkag mus rau hauv cable thiab ua rau cov hluav taws xob kev puas tsuaj sab hauv. Ib qho ntawm cov kev ua tau zoo tshaj plaws kom ua tiav cov dej thaiv yog los ntawm kev siv dej thaiv cov xov paj hauv kev tsim kho cable.
Dej thaiv cov xov paj yog feem ntau ua los ntawm cov khoom siv hydrophilic uas o thaum nws los rau hauv kev sib cuag nrog dej. Qhov o tau tsim ib txoj kev thaiv uas tiv thaiv dej los ntawm nkag mus rau cable. Cov ntaub ntawv siv feem ntau yog nthuav dav polyethylene (EPE), polypropylene (PP), thiab sodium polyacrylate (spa).
EPE yog qhov tsawg-ceev, high-molecular-phaus polyethylene uas muaj dej tau zoo heev Thaum EPE fibers tuaj rau hauv kev sib cuag nrog dej, lawv nqus dej thiab nthuav dav, tsim kom muaj lub ntsej muag dej ntws ib puag ncig cov neeg saib xyuas. Qhov no ua rau EPE cov khoom siv dej zoo rau cov dej thaiv cov xov paj, vim nws muab qib siab ntawm kev tiv thaiv dej ingress.
Pp yog lwm cov khoom siv uas feem ntau siv rau. PP Fibers yog hydrophobic, uas txhais tau tias lawv repel dej. Thaum siv nyob rau hauv ib qho cable, pp fibers tsim ib qho kev thaiv uas tiv thaiv dej los ntawm kev nkag mus rau cable. PP Fibers feem ntau yog siv hauv kev sib xyaw nrog EPE fibers los muab ib txheej ntxiv ntawm kev tiv thaiv tawm tsam dej ingress.
Sodium polyacrylate yog superabsorbent polymer uas feem ntau siv. Sodium Polyacrylate fibers muaj lub peev xwm siab kom nqus dej, uas ua rau lawv muaj kev cuam tshuam rau dej ingress. Cov fibers nqus dej thiab nthuav tawm, tsim kom muaj ib lub foob ua si ntawm cov neeg saib xyuas.
Dej thaiv cov xov paj yog feem ntau koom rau hauv cable thaum lub sijhawm tsim khoom. Lawv feem ntau yog ntxiv ua txheej ib ncig ntawm cov hluav taws xob ntawm cov hluav taws xob, nrog rau lwm yam xws li rwb thaiv tsev thiab hnav khaub ncaws. Cov khoom tau muab tso rau hauv cov kev xaiv tswv yim nyob rau hauv lub cable, xws li ntawm cov cable xaus lossis hauv cov cheeb tsam uas nquag muaj kev tiv thaiv kev tiv thaiv cov dej puas.
Hauv kev xaus, dej thaiv cov xov paj yog ib qho tseem ceeb hauv cable rau cov ntawv thov uas yuav tsum tau tiv thaiv cov dej ingress. Kev siv dej thaiv cov xov paj, ua los ntawm cov ntaub ntawv xws li EPE, PP, thiab sodium polyacrylate, kom muaj kev ntseeg tau thiab muaj peev xwm ntawm txoj kev sib cav.
