Geomembraneyog cov khoom siv tsis muaj dej tsis zoo thiab cov khoom thaiv raws li cov khoom siv polymer siab.Feem ntau muab faib ua low-density polyethylene (LDPE) geomembranes, high-density polyethylene(HDPE) geomembranes, thiab EVA geomembranes.Warp knitted composite geomembrane txawv ntawm cov geomembrane dav dav.Nws tus yam ntxwv yog qhov kev sib tshuam ntawm longitude thiab latitude tsis yog nkhaus, thiab txhua tus nyob rau hauv ib tug ncaj lub xeev.Bundle ob lub nro nrog braided hlau, uas tuaj yeem sib npaug sib npaug, tiv thaiv sab nraud, faib kev ntxhov siab, thiab thaum siv lub zog sab nraud los kua muag cov khoom, cov xov paj yuav sib sau ua ke ntawm qhov pib tawg, ua rau tsim kua muag.Thaum siv warp knitted composite, warp knitted threads rov qab threaded ntawm fiber ntau txheej ntawm warp, weft, thiab geotextile, ua rau peb interwoven rau hauv ib tug.Yog li, warp knitted composite geomembrane tsis tsuas yog muaj cov yam ntxwv ntawm lub zog tensile siab thiab qis elongation, tab sis kuj muaj cov dej tsis zoo ntawm geomembrane.Yog li ntawd, warp knitted composite geomembrane yog ib hom khoom siv los tiv thaiv cov dej ntws uas muaj cov haujlwm ntawm kev txhawb zog, kev sib cais, thiab kev tiv thaiv.Nws yog qib siab siv cov khoom siv geosynthetic hauv ntiaj teb niaj hnub no.

Lub zog tensile siab, tsis tshua muaj elongation, niaj hnub longitudinal thiab transverse deformation, siab kua muag kuj, zoo heev hnav tsis kam, thiab muaj zog dej tsis kam..Nws qhov kev ua tau zoo los tiv thaiv kev ua haujlwm feem ntau yog nyob ntawm kev ua haujlwm ntawm cov yeeb yaj kiab yas.Cov yeeb yaj kiab yas siv los tiv thaiv kev nkag mus hauv tsev thiab txawv teb chaws feem ntau suav nrog (PVC) polyethylene (PE) thiab ethylene / vinyl acetateCopolymer (EVA), uas yog cov ntaub ntawv hloov tau ntawm Polymer chemistry nrog me me lub ntiajteb txawj nqus, muaj zog extensibility, siab adaptability rau deformation, corrosion kuj, tsis kub tsis kam thiab zoo Frost kuj.Kev pabcuam lub neej ntawm cov khoom sib xyaw geomembrane feem ntau yog txiav txim siab los ntawm seb cov yas zaj duab xis puas tau poob nws txoj kev tawm tsam thiab dej sib cais.Raws li lub teb chaws tus qauv ntawm lub Soviet Union, polyethylene zaj duab xis nrog ib tug tuab ntawm 0.2m thiab ib tug stabilizer siv nyob rau hauv hydraulic engineering yuav ua hauj lwm mus txog 40-50 xyoo nyob rau hauv dej ntshiab thiab 30-40 xyoo nyob rau hauv cov dej phwj tuaj.Yog li ntawd, kev pabcuam lub neej ntawm cov khoom sib xyaw geomembrane yog txaus kom ua tau raws li qhov xav tau los tiv thaiv cov dej ntws ntawm lub pas dej.
