Nqe lus piav qhia:
Filament Non-woven Geotextile yog Nruam Filament Needle punched non-woven Geotextile uas ua los ntawm Polyester, tsim los ntawm cov txheej txheem ntawm rab koob punching thiab thermally bounding, muaj kev ua tau zoo tshaj plaws rau ib chav tsev qhov hnyav.Filament Non woven Geotextile muab kev daws teeb meem zoo thiab kev lag luam ntawm kev sib cais, pom, tso dej, kev tiv thaiv thiab kev txhawb zog rau cov haujlwm engineering.
Khoom nta:
Lim
Thaum dej dhau los ntawm cov nplua-grained mus rau coarse grained txheej, Non-woven Geotextiles tuaj yeem khaws cov khoom zoo.Xws li thaum dej ntws los ntawm cov av xuab zeb mus rau hauv Geotextile qhwv gravel ntws.
Kev sib cais
cais ob txheej ntawm av nrog cov khoom sib txawv ntawm lub cev, xws li kev sib cais ntawm txoj kev gravel los ntawm cov ntaub ntawv mos sub-base.
Dej ntws
kom ntws cov kua los yog roj los ntawm lub dav hlau ntawm cov ntaub, uas ua rau cov dej ntws los yog qhov cua ntawm cov av, xws li cov roj cua txheej hauv lub hau npog.
Kev txhawb zog
txhawm rau txhim kho cov kabmob muaj peev xwm ntawm cov qauv av tshwj xeeb, xws li kev txhawb nqa ntawm phab ntsa tuav.
