Hongyue nonwoven composite geomembrane tuaj yeem kho
Lus piav qhia luv luv:
Composite geomembrane (composite anti-seepage membrane) tau muab faib ua ib daim ntaub thiab ib daim nyias nyias thiab ob daim ntaub thiab ib daim nyias nyias, nrog rau qhov dav ntawm 4-6m, qhov hnyav ntawm 200-1500g / sq. tensile lub zog, kua muag kuj, thiab tawg. High, cov khoom muaj cov yam ntxwv ntawm lub zog siab, zoo elongation kev ua tau zoo, loj deformation modulus, acid thiab alkali tsis kam, corrosion kuj, aging kuj, thiab zoo impermeability. Nws tuaj yeem ua tau raws li qhov xav tau ntawm kev tsim vaj tsev engineering xws li kev txuag dej, kev tswj hwm hauv nroog, kev tsim kho, kev thauj mus los, subways, tunnels, engineering kev tsim kho, kev tiv thaiv kev tawm tsam, kev sib cais, kev txhawb nqa, thiab kev tiv thaiv kev tawg. Nws yog feem ntau siv los tiv thaiv cov dej ntws tawm ntawm cov kwj dej thiab cov kwj deg, thiab kev kho cov pa phem ntawm cov khib nyiab pov tseg.
Khoom Description
Composite geomembrane yog ib qho khoom siv impervious muaj li ntawm geotextile thiab geomembrane, uas yog siv rau impermeability. Composite geomembrane muab faib ua ib daim ntaub thiab ib daim nyias nyias thiab ob daim ntaub thiab ib daim nyias nyias, nrog qhov dav dav ntawm 4-6m, qhov hnyav ntawm 200-1500g / m2, qhov ntsuas lub cev thiab cov tshuab ua haujlwm siab xws li tensile, tsim kua muag thiab lub ru tsev tawg. Nws tuaj yeem ua tau raws li qhov xav tau ntawm kev txuag dej, hauv nroog, kev tsim kho, kev thauj mus los, subway, qhov av thiab lwm yam kev tsim vaj tsev. Vim yog xaiv cov khoom siv polymer thiab ntxiv cov tshuaj tiv thaiv kev laus hauv cov txheej txheem tsim khoom, nws tuaj yeem siv rau hauv qhov chaw kub tsis zoo.
Khoom
1. Waterproof thiab impermeable: composite geomembrane muaj siab waterproof thiab impermeable kev ua tau zoo, uas tuaj yeem tiv thaiv kev nkag mus ntawm cov dej hauv av thiab dej hauv av;
2. Lub zog tensile siab: composite geomembrane muaj lub zog tensile zoo thiab tuaj yeem tiv taus sab nraud zoo;
3. Kev laus tsis kam: cov khoom sib xyaw geomembrane muaj kev laus zoo heev thiab tuaj yeem tswj tau lub zog thiab tawv ntawm cov khoom siv ntev;
4. Tshuaj corrosion kuj: composite geomembrane muaj lub siab kam rau tshuaj corrosion nyob rau hauv ib puag ncig thiab tsis yooj yim cuam tshuam los ntawm cov tshuaj.
Daim ntawv thov
1. Kev tiv thaiv ib puag ncig: composite geomembrane tuaj yeem siv rau hauv thaj chaw tiv thaiv ib puag ncig xws li kev kho dej khib nyiab, kev kho dej phwj tuaj, pov tseg thiab pov tseg pov tseg pov tseg, ua si zoo los tiv thaiv cov dej ntws.
2. Hydraulic engineering: composite geomembrane tuaj yeem siv rau hauv DAMS, reservoirs, tunnels, Bridges, seawalls thiab lwm yam hydraulic engineering, uas tuaj yeem tiv thaiv kom tsis txhob muaj kuab paug thiab muaj kuab paug zoo.
3. Agricultural cog: composite geomembrane siv tau rau orchard drainage, channel cover, zaj duab xis cover, pas dej ua ke cover thiab lwm yam kev ua liaj ua teb kev tsim kho, nrog ib tug zoo anti-seepage nyhuv.
4. Kev tsim kho txoj kev: composite geomembrane tuaj yeem siv rau hauv qhov av, txoj kev hauv tsev, choj, culvert thiab lwm yam kev tsim kho kev lag luam los muab cov kev daws teeb meem txhim khu kev qha rau txoj kev waterproofing.
