4 Cov Lus Qhia Txog Cov nyom dag
1. Nyom fiber ntau hnav
Thaum siv sijhawm ntev, cov khoom siv dag zog yuav raug hnav nrog fibers forking thiab splitting thiab txawm tias poob tawm, tshwj xeeb tshaj yog nyob rau hauv cov chaw uas muaj tsheb loj xws li tsev kawm ntawv chaw ua si. Kev ua si hnyav heev thiab siv sijhawm ntev yuav ua rau lub neej luv luv ntawm cov nyom nyom nyom. Yog li ntawd, cov khoom uas muaj fiber ntau zoo thiab muaj peev xwm tiv thaiv hnav zoo heev yuav tsum tau xaiv thaum tib neeg yuav cov nyom dag kom txo tau cov fiber ntau hnav, zam fiber ntau poob tawm thiab turf hloov thiab thaum kawg txo qis kev lag luam.
2. Nyom fiber xim fading
Muaj ntau ntau yam ua rau xim fading ntawm nyom fibers: (1). Tus neeg saib xyuas tsis zoo los tiv thaiv kev laus lossis cov txheej txheem tsim khoom tsis zoo. (2). Ib puag ncig yam xws li lub cheeb tsam UV hluav taws xob, kua qaub nag yaig, muaj kuab paug, thiab lwm yam. (3). Cov khoom tsis zoo infilling uas paug thiab ploj xim ntawm cov nyom fibers.
3. Turf backing decays
Cov thaub qab ntawm cov nyom dag yog ua los ntawm cov ntaub ntawv PP. Thaum muab tso rau sab nraum zoov, nws raug cua, tshav ntuj thiab dej nag thiab nws yuav ua rau tawg. Tsis tas li ntawd, qee qhov chaw tsis muaj dej phwj zoo. Thaum lub nraub qaum yog tsau rau hauv dej ntev, nws yuav lwj thiab ua kom cov txheej txheem kev laus ntawm cov nyom dag nyom.
4. Loose seams
Nws yog qhov paub zoo tias qhov chaw hluavtaws nyom yog paved nrog ob peb turfs thiab tom qab ntawd siv cov nplaum nplaum. Yog li hauv kev teeb tsa, koj yuav tsum ntiav cov kws tshaj lij kev teeb tsa pab pawg thiab yuav cov kua nplaum zoo siab rau adhesion ntawm cov nyom dag. Txwv tsis pub, nws muaj feem ntau rau cov kab dawb ua xoob thiab cov seams yuav tawg. Yog tias ua tau zoo, cov seams yuav tsum muaj tib lub neej raws li cov nyom dag.
