Muaj peb lub ntsiab series ntawm geotextiles:
1. Needle-punched non-woven geotextile
Raws li cov khoom siv, koob-punched non-woven geotextiles tuaj yeem muab faib ua polyester geotextiles thiab polypropylene geotextiles;lawv tuaj yeem muab faib ua cov fiber ntau geotextiles ntev thiab luv-fiber geotextiles.Needle-punched non-woven geotextile yog ua los ntawm polyester lossis polypropylene fiber ntau los ntawm txoj kev acupuncture, feem ntau siv specification yog 100g / m2-1500g / m2, thiab lub hom phiaj tseem ceeb yog txoj kab nqes tiv thaiv dej, hiav txwv, thiab pas dej embankment, dej nyab tswj thiab cawm thaum muaj xwm txheej ceev, thiab lwm yam. Cov no yog txoj hauv kev zoo los tswj cov dej thiab av thiab tiv thaiv cov kav dej los ntawm kev rov qab pom.Luv fiber ntau geotextiles feem ntau suav nrog polyester koob-punched geotextiles thiab polypropylene koob-punched geotextiles, ob qho tib si uas tsis yog-woven geotextiles.Lawv yog cov yam ntxwv los ntawm kev yooj yim, acid thiab alkali tsis kam, corrosion kuj, aging kuj, thiab yooj yim siv.Ntev fiber ntau geotextiles muaj qhov dav ntawm 1-7m thiab qhov hnyav ntawm 100-800g / ㎡;lawv yog ua los ntawm high-strength polypropylene los yog polyester ntev fiber ntau filaments, manufactured nrog tshwj xeeb cov tswv yim, thiab hnav-resistant, tawg-resistant, thiab muaj zog tensile siab.
2. Composite geotextile (Needle-punched non-woven npuag + PE zaj duab xis)
Composite geotextiles yog tsim los ntawm compounding polyester luv fiber koob-punched non-woven fabrics thiab PE zaj duab xis, thiab feem ntau muab faib ua: "ib daim ntaub + ib zaj duab xis" thiab "ob daim ntaub thiab ib zaj duab xis".Lub hom phiaj tseem ceeb ntawm cov khoom sib xyaw geotextile yog los tiv thaiv cov dej ntws, haum rau kev tsheb ciav hlau, txoj kev loj, tunnels, subways, tshav dav hlau, thiab lwm yam dej num.
3. Non-woven thiab woven composite geotextiles
Hom geotextile no yog tsim los ntawm rab koob-punched non-woven npuag thiab yas woven ntaub.Nws yog tsuas yog siv rau lub hauv paus kev txhawb zog thiab kev tsim vaj tsev yooj yim rau kev kho cov permeability coefficient.
