Dawb 100% polyester tsis-woven geotextile rau kev tsim kho txoj kev pas dej
Kev Piav Qhia Luv:
Cov ntaub geotextiles uas tsis yog woven muaj ntau yam zoo, xws li cua nkag, lim dej, rwb thaiv tsev, nqus dej, tiv dej, rub tau, zoo nkaus li zoo, mos, lub teeb, elastic, rov qab tau, tsis muaj kev taw qhia ntawm cov ntaub, tsim khoom siab, ceev ntau lawm thiab tus nqi qis. Tsis tas li ntawd, nws kuj muaj lub zog tensile siab thiab tiv taus kua muag, ntws dej zoo ntsug thiab kab rov tav, cais tawm, ruaj khov, txhawb nqa thiab lwm yam haujlwm, nrog rau kev ua tau zoo heev thiab kev lim dej.
Cov Khoom Piav Qhia
Cov geotextiles uas tsis yog woven yog cov ntaub ntawv geosynthetic uas dej-permeable ua los ntawm cov fibers hluavtaws los ntawm kev siv koob lossis weaving. Nws muaj kev lim dej zoo heev, kev cais tawm, kev txhawb nqa thiab kev tiv thaiv, thaum lub zog tensile siab, permeability zoo, tiv taus kub siab, tiv taus khov, tiv taus laus, tiv taus corrosion. Cov geotextiles uas tsis yog woven yog siv dav hauv ntau qhov project, xws li txoj kev, txoj kev tsheb ciav hlau, embankments, av-pob zeb DAMS, tshav dav hlau, chaw ua si nawv, thiab lwm yam, los txhawb lub hauv paus tsis muaj zog, thaum ua lub luag haujlwm ntawm kev cais tawm thiab kev lim dej. Tsis tas li ntawd, nws kuj tsim nyog rau kev txhawb nqa hauv backfill ntawm cov phab ntsa khaws cia, lossis rau kev khi cov vaj huam sib luag ntawm cov phab ntsa khaws cia, nrog rau kev tsim cov phab ntsa khaws cia qhwv lossis abutments.
Feature
1. Lub zog siab: nyob rau hauv tib lub gram hnyav specifications, lub zog tensile ntawm ntev silk spunbonded needled nonwoven geotextiles nyob rau hauv tag nrho cov lus qhia yog siab dua li ntawm lwm yam needled nonwovens, thiab muaj lub zog tensile siab dua.
2. Kev ua tau zoo ntawm cov av noo: Cov geotextile no muaj kev ua tau zoo ntawm cov av noo, tuaj yeem tswj tau qhov ruaj khov hauv kev siv mus sij hawm ntev, thiab tsis yooj yim rau kev hloov pauv.
3. Muaj zog tiv taus corrosion, laus tiv taus thiab kub tiv taus: ntev silk spunbonded needled nonwoven geotextile muaj kev tiv taus corrosion zoo heev, laus tiv taus thiab kub tiv taus, thiab siv tau ntev hauv qhov chaw hnyav yam tsis muaj kev puas tsuaj.
4. Kev ua tau zoo heev ntawm kev txuag dej: nws cov qhov hws tuaj yeem tswj tau zoo kom ua tiav qee qhov permeability, uas yog qhov tsim nyog rau cov haujlwm uas xav tau tswj cov dej ntws.
5. Kev tiv thaiv ib puag ncig thiab ruaj khov, kev lag luam thiab ua haujlwm tau zoo: piv rau cov ntaub ntawv ib txwm muaj, cov ntaub ntawv geotextile ntev uas muaj cov xov paj rwb sib txuas ua ke zoo dua rau ib puag ncig, tuaj yeem rov ua dua tshiab thiab rov siv dua, txo qhov kev cuam tshuam ib puag ncig, thiab muaj lub zog ruaj khov, kev raug mob mus sij hawm ntev tseem tuaj yeem tswj tau qhov ua tau zoo, txo cov nqi txij nkawm.
6. Kev tsim kho yooj yim: kev tsim kho yooj yim, tsis xav tau cov thev naus laus zis thiab khoom siv nyuaj, txuag cov neeg ua haujlwm thiab cov khoom siv, tsim nyog rau cov haujlwm sai.
Daim Ntawv Thov
Siv rau thaj chaw ntawm txoj kev loj, txoj kev tsheb ciav hlau, pas dej, ntug dej hiav txwv rau kev txhawb nqa, lim dej, sib cais thiab ntws dej, tshwj xeeb tshaj yog siv rau hauv cov pas dej ntsev thiab thaj chaw faus khib nyiab. Feem ntau siv rau kev lim dej, txhawb nqa thiab sib cais.
