staple fibers koob punched geotextile
Product Description
Qhov luv fiber ntau geotextile muaj cov dej zoo conductivity, thiab luv luv fiber koob-punched non-woven geotextile tuaj yeem tsim kom muaj kev nyab xeeb rau cov kav dej hauv cov qauv hauv av, thiab tso tawm cov kua ntau dhau thiab cov roj pov tseg hauv cov qauv av;siv cov geotextiles los txhim kho cov av zoo.Compressive zog thiab anti-deformation theem, txhim kho stability ntawm lub tsev qauv, thiab txhim kho av zoo;Ua tau zoo diffuse, xa lossis yaj cov kev ntxhov siab kom tsis txhob muaj av puas tsuaj vim yog sab nraud;Tsis txhob sab sauv thiab qis ntawm cov xuab zeb, gravel, av Nws yog doped ntawm lub cev thiab cov cement;lub mesh cov ntaub so ntswg tsim los ntawm amorphous connective cov ntaub so ntswg muaj strain thiab autonomous txav, yog li cov pores tsis yooj yim rau thaiv;nws muaj dej permeability siab thiab tseem tuaj yeem tswj tau zoo nyob rau hauv lub siab ntawm av thiab dej Dej permeability;nrog polypropylene ntaub los yog polyester thiab lwm yam tshuaj fibers raws li cov ntaub ntawv tseem ceeb, nws yog corrosion-resistant, non-erosive, tsis-kab-resistant, thiab muaj anti-oxidation specifications thiab qauv: qhov dav yuav ncav cuag 6 meters.Nws yog cov khoom siv dav tshaj plaws hauv Suav teb, kev siv qhov zoo: 100-600g / ㎡;
Staple fibers koob punched non-woven geotextile yog ua los ntawm PP los yog PET staple fibers thiab ua tiav los ntawm daim carding cross-laying khoom thiab koob punched khoom.Nws muaj cov haujlwm ntawm kev sib cais, pom, tso dej, kev txhawb zog, kev tiv thaiv thiab kev saib xyuas.
Khoom Taw Qhia
