Geomembrane chinhu chisingapindi mvura uye chinodzivirira chakavakirwa pahupamhi hwemamorekuru huremu mapolymer. Iyo inonyanya kukamurwa kuita yakaderera-density polyethylene (LDPE) geomembranes, yakakwirira-density polyethylene (HDPE) geomembranes, uye EVA geomembranes. Knitted composite geomembrane yakasiyana neyakajairwa geomembranes. Chimiro chayo ndechekuti mharadzano yemitsara yelongitudo nelatitude haina kukombama, uye imwe neimwe iri muchimiro chakatwasuka. Kushandisa shinda yakarukwa kuti usunge zvakasimba zviviri izvi zvinogona kuwana yunifomu kuwiriranisa, kumirisana nemasimba ekunze, kugovera kushushikana, uye kana simba rekunze rinoshandiswa richibvarura zvinhu, shinda inoungana pamwe nekutsemuka kwekutanga, ichiwedzera kuramba kubvarura. Panguva yekurukwa kwewarp, shinda inorukwa inopfuudzwa kakawanda pakati pewap, weft, uye fiber layers yegeomembrane kuti irukwe zvitatu kuita chimwe. Naizvozvo, warp yakarukwa composite geomembranes haingove nehunhu hwekusimba kwepamusoro uye kureba kwakadzika, asiwo kuve nekusapinda kwemvura kuita kwegeomembranes. Naizvozvo, warp yakarukwa composite geomembrane inopesana-seepage zvinhu zvine mabasa ekusimbisa, kuzviparadzanisa nevamwe, uye kudzivirira. Iko kushandiswa kwepamusoro-soro kwe geosynthetic composite zvinhu pasi rese nhasi.
Kusimba kwakasimba, kureba kwakadzika, yunifomu yehurefu uye kuchinjika, kukwirira kwemisodzi, kusapfeka zvakanaka, uye kusimba kwemvura yakasimba. jira. Iyo anti-seepage performance inonyanya kuenderana ne-anti-seepage performance yefirimu repurasitiki. Mafirimu epurasitiki anoshandiswa anti-seepage application mukati mekunze uye kunze kwenyika kunyanya anosanganisira (PVC) polyethylene (PE) uye ethylene/vinyl acetate copolymer (EVA). Iwo imhando yepolymer kemikari inochinjika zvinhu ine diki chaiyo giravhiti, kuwedzera kwakasimba, kuchinjika kwepamusoro kune deformation, corrosion resistance, kushomeka kwekushisa, uye kunaka kwechando. Hupenyu hwesevhisi yeakaumbwa geomembranes inonyanya kutsanangurwa kana iyo firimu repurasitiki rinorasikirwa ne-anti-seepage uye inodzivirira mvura. Maererano neSoviet yenyika mitemo, mafirimu e polyethylene ane hupamhi hwe 0.2m uye stabilizers anoshandiswa muinjiniya yemvura anogona kushanda kwemakore 40-50 pasi pemvura yakachena uye makore 30-40 pasi pemamiriro emvura. Nokudaro, hupenyu hwebasa remusanganiswa geomembrane hwakakwana kuti usangane ne-anti-seepage zvinodiwa zvedhamu.
