Geomembrane yog cov khoom siv tsis muaj dej tsis zoo thiab cov khoom thaiv raws li cov khoom hnyav molecular polymers. Nws feem ntau muab faib ua low-density polyethylene (LDPE) geomembranes, high-density polyethylene (HDPE) geomembranes, thiab EVA geomembranes. Knitted composite geomembrane txawv ntawm cov geomembranes dav dav. Nws cov yam ntxwv yog tias kev sib tshuam ntawm longitude thiab latitude kab tsis yog nkhaus, thiab txhua tus nyob hauv ib lub xeev ncaj. Siv cov xov braided kom ruaj khov khi ob tuaj yeem ua tau zoo sib xws, tiv thaiv sab nraud, faib kev ntxhov siab, thiab thaum siv cov quab yuam 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 lub sij hawm warp knitting composite, lub warp knitting xov yog rov dhau ntawm warp, weft, thiab fiber ntau txheej ntawm geomembrane rau weave peb rau hauv ib qho. Yog li ntawd, warp knitted composite geomembranes tsis tsuas yog muaj cov yam ntxwv ntawm lub zog tensile siab thiab qis elongation, tab sis kuj muaj cov dej tsis zoo ntawm geomembranes. Yog li ntawd, warp knitted composite geomembrane yog cov 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 ib qho kev siv siab heev ntawm geosynthetic composite cov ntaub ntawv thoob ntiaj teb niaj hnub no.
Lub zog tensile siab, tsis tshua muaj elongation, niaj hnub longitudinal thiab transverse deformation, siab tsim kua muag kuj, zoo heev hnav tsis kam, thiab muaj zog dej tsis kam.. ntaub. Nws cov kev ua tau zoo los tiv thaiv kev ua haujlwm feem ntau yog nyob ntawm qhov kev ua tau zoo ntawm cov yeeb yaj kiab yas. Cov yeeb yaj kiab yas siv los tiv thaiv cov ntawv thov hauv tsev thiab thoob ntiaj teb feem ntau suav nrog (PVC) polyethylene (PE) thiab ethylene / vinyl acetate copolymer (EVA). Lawv yog ib hom ntawm cov khoom siv polymer hloov tau yooj yim nrog lub ntiajteb txawj nqus me me, muaj zog extensibility, siab adaptability rau deformation, corrosion kuj, tsis kub tsis kam, thiab Frost tsis kam. Kev pabcuam lub neej ntawm cov khoom sib xyaw geomembranes feem ntau yog txiav txim siab los ntawm seb cov yas zaj duab xis poob nws cov khoom tiv thaiv dej thiab dej-resistant. Raws li Soviet lub teb chaws qauv, polyethylene films nrog ib tug tuab ntawm 0.2m thiab stabilizers siv nyob rau hauv dej engineering yuav ua hauj lwm rau 40-50 xyoo nyob rau hauv dej ntshiab thiab 30-40 xyoo nyob rau hauv dej phwj tuaj. Yog li ntawd, kev pab cuam lub neej ntawm kev sib xyaw geomembrane yog txaus kom ua tau raws li qhov yuav tsum tau ua los tiv thaiv cov dej ntws ntawm lub pas dej.
