Qhov sib txawv ntawm cov geotextile luv luv thiab cov geotextile ntev

Cov geotextile fiber luv thiab cov geotextile fiber ntev yog ob hom geotextiles uas siv ntau hauv kev tsim kho vaj tse, thiab lawv muaj qee qhov sib txawv hauv kev ua tau zoo thiab kev siv. Tsab xov xwm no yuav qhia txog qhov sib txawv ntawm cov geotextile fiber luv thiab cov geotextile fiber ntev kom meej.

1. Cov ntaub ntawv thiab cov txheej txheem tsim khoom

Cov ntaub ntawv staple fiber geotextiles yog ua los ntawm cov polymers staple fiber (xws li polyester fibers) nrog cov fiber luv luv, feem ntau ntawm ob peb millimeters. Cov txheej txheem tsim khoom ntawm staple fiber geotextile yog qhov yooj yim thiab tus nqi qis, yog li nws tau siv dav hauv kev tsim kho vaj tse.

Cov geotextile ntev fiber ntau yog ua los ntawm cov polymer ntev fiber (polyester chip), thiab nws cov fiber ntev yog ntev, feem ntau ntawm kaum tawm millimeters. Cov txheej txheem tsim cov geotextiles ntev fiber ntau yog qhov nyuaj thiab kim, tab sis nws muaj zog dua thiab ruaj khov.

2. Cov yam ntxwv ua tau zoo

1. Lub zog vs. Kev ruaj khov

Cov geotextiles ntev fiber ntau muaj zog thiab ruaj khov dua, thiab tuaj yeem tiv taus lub zog siab dua thiab lub zog tensile, yog li lawv siv dav hauv kev tsim kho vaj tse uas lawv xav tau dais cov khoom thauj loj dua. Txawm li cas los xij, lub zog thiab ruaj khov ntawm cov geotextile fiber staple yog qis heev, thiab nws tsim nyog rau kev tsim kho vaj tse dav dav.

2. Kev nkag tau dej

Cov geotextile fiber ntau muaj cov dej permeability zoo, uas tuaj yeem tso dej tawm sai sai los ntawm cov ntaub nto thiab ua kom cov av qhuav. Txawm li cas los xij, cov dej permeability ntawm cov geotextile fiber ntev tsis zoo, tab sis nws tuaj yeem nkag mus rau hauv cov qauv microporous ntawm cov ntaub nto.

3. Kev tiv thaiv tshuaj lom neeg

Cov geotextile ntev fiber muaj kev tiv thaiv zoo ntawm cov tshuaj lom neeg thiab tuaj yeem tiv taus kev yaig ntawm cov kua qaub, alkalis thiab lwm yam tshuaj lom neeg. Txawm li cas los xij, kev tiv thaiv tshuaj lom neeg ntawm cov geotextiles fiber ntau tsis zoo, yog li yuav tsum tau ua raws li kev tiv thaiv.

4. Kev tiv thaiv UV

Cov geotextile fiber ntev muaj kev tiv thaiv ultraviolet zoo, uas tuaj yeem tiv taus kev yaig ntawm cov duab ultraviolet thiab tswj lub zog thiab kev ua haujlwm ntawm cov ntaub. Txawm li cas los xij, qhov kev tiv thaiv ultraviolet ntawm cov geotextiles fiber ntau tsis zoo, yog li yuav tsum tau ua cov kev ntsuas tiv thaiv sib xws.

3. Cov teb thov

1. Kev tsim kho hydraulic

Hauv cov haujlwm txuag dej, cov geotextiles luv luv thiab cov geotextiles ntev tau siv dav. Cov geotextile luv luv tuaj yeem siv rau kev txhawb nqa thiab kev tiv thaiv ntawm ntug dej, pas dej thiab lwm qhov chaw, thaum cov geotextile ntev tuaj yeem siv rau kev tsim cov haujlwm txuag dej loj xws li cov pas dej thiab pas dej.

2. Kev tsim kho txoj kev

Hauv kev tsim kho txoj kev, cov geotextile luv luv tuaj yeem siv rau kev txhawb nqa thiab kev tiv thaiv ntawm subgrade thiab pavement, thaum cov geotextile ntev ntev tuaj yeem siv rau kev tsim kho txoj kev loj, kev tsheb ciav hlau thiab lwm txoj kab tsheb khiav.

3. Kev Tsim Kho Kev Tiv Thaiv Ib puag ncig

Hauv cov haujlwm tiv thaiv ib puag ncig, cov geotextiles luv luv tuaj yeem siv rau hauv kev tsim kho cov haujlwm kho ib puag ncig xws li kev kho av thiab chaw pov tseg, thaum cov geotextiles ntev tuaj yeem siv rau hauv kev tsim kho cov haujlwm tiv thaiv ib puag ncig xws li kev kho dej phwj tuaj thiab kev kho dej.

Hauv ntej, muaj qhov sib txawv pom tseeb ntawm cov geotextiles luv luv thiab cov geotextiles ntev hauv cov ntaub ntawv, cov txheej txheem tsim khoom, cov yam ntxwv kev ua tau zoo thiab cov teb thov. Hauv kev tsim kho vaj tse, hom geotextile tsim nyog yuav tsum tau xaiv raws li qhov xav tau tshwj xeeb thiab cov xwm txheej tiag tiag.
