Dab tsi yog Cov yam ntxwv ntawm Geomembranes

Composite geomembrane siv yas zaj duab xis ua impermeable substrate, thiab non-woven fabric composite geoimpermeable khoom, nws impermeability kev ua tau zoo feem ntau yog nyob ntawm qhov kev ua tau zoo ntawm cov yas zaj duab xis. Cov ntawv thov hauv tsev thiab txawv teb chaws los tiv thaiv cov yeeb yaj kiab yas, feem ntau yog polyvinyl chloride (PVC), polyethylene (PE), ethylene / vinyl acetate copolymer (EVA), lawv yog cov khoom siv polymer hloov tau yooj yim, me me tshwj xeeb lub ntiajteb txawj nqus, muaj zog elongation, siab adaptability. deformation, corrosion kuj, tsis kub tsis kam, zoo Frost kuj.
Raws li Soviet lub teb chaws tus qauv, polyethylene zaj duab xis nrog lub thickness ntawm 0.2m ntxiv rau stabilizer polyethylene zaj duab xis tuaj yeem ua haujlwm rau 40 ~ 50 xyoo nyob rau hauv dej huv, thiab 30 ~ 40 xyoo nyob rau hauv dej phwj tuaj. Yog li ntawd, kev pab cuam lub neej ntawm cov khoom sib xyaw geomembrane yog txaus kom ua tau raws li lub neej kev pab cuam ntawm lub pas dej da dej tiv thaiv kev tiv thaiv.
