Yog Non-woven Geotextile
Nov 23, 2023
Non-woven fabricstxhais tau hais tias cov txheej txheem ntau lawm tsis tas yuav tsum tau weaving, thiab geotextiles yog siv rau kev ua haujlwm geotechnical. Muaj ob hom non-woven geotextiles, ib qho yog koob-punched geotextile thiab lwm yam yog polyester filament geotextile. Geotextiles yog tsim los ntawm polyester thiab polypropylene. Nws lub luag haujlwm tseem ceeb yog cais cov khoom siv hauv tsev. Nws muaj qhov zoo permeability, thiab lub tsev ruaj khov, thiab tuaj yeem tswj tau ntau hom av los ntawm kev hloov cov av zoo.
Geotextiles kuj yog tsim los ntawm cov dej-permeable hluavtaws ua los ntawm ntaub. Cov khoom zoo li qub, feem ntau 4-6 meters dav thiab 50-100 meters ntev. Geotextiles muab faib ua geotextiles zoo tib yam thiab tshwj xeeb geotextiles. Cov khoom no muaj lub luag haujlwm ntawm kev lim dej, dej conduction, barrier, reinforcement, leakage tiv thaiv, tiv thaiv, thiab lwm yam, thiab yog lub teeb nyob rau hauv kev ntxhib los mos. Nws muaj zoo toughness thiab lub zog, tab sis tsis zoo dej nqus. Anti-siab kub, tiv thaiv txias, tiv thaiv kev laus, tiv thaiv oxidation. Cov ntaub tsis-woven tuaj yeem siv dav hauv txoj kev paving, kev tiv thaiv txoj kab nqes, ib puag ncig ntsuab, kev txuag dej, kev ruaj ntseg hauv av, thiab lwm yam.
Raws li nws lub hauv paus ntsiab lus, qauv, thiab txoj kev, nws tau muab faib ua luv fiber koob-punched geotextile (qhov tseem ceeb tseem hu ua geotextile), tshwj xeeb tsis-woven geotextile (woven geotextile kuj hu ua filament geotextile), tes-woven geotextile, koob-punched geotextile ntaub. Kev lag luam geotextiles muaj cov yam ntxwv ntawm cov tshuaj tiv thaiv kab mob antioxidant, tiv thaiv qhov kub thiab txias, tiv taus txias, zoo toughness, yooj yim siv, thiab lwm yam, thiab tuaj yeem siv rau hauv txoj kev. txoj kev tsheb ciav hlau. dykes. Kev tu, pom, thiab kev txhawb nqa ntawm cov qauv hydraulic. Ib qho geotextile nrog ib lub zog tensile yog faus rau hauv av. Lub zog thiab ruaj khov ntawm cov av yog txhim kho thiab inhibited los ntawm kev sib cuam tshuam ntawm geotextile thiab av interface.
