Geomembranechinhu chisingapindi mvura uye chinodzivirira chakavakirwa pane yakakwira polymer.Yakakamurwa kuita yakaderera density polyethylene (LDPE) geomembranes, yakakwirira-density polyethylene(HDPE) geomembranes, uye EVA geomembranes.Warp knitted composite geomembrane yakasiyana neyakajairwa geomembrane.Chimiro chayo ndechekuti mharadzano yelongitude nelatitude haina kukombama, uye imwe neimwe iri muchimiro chakatwasuka.Unganidza maviri akasimba newaya yakarukwa, inogona kuwiriraniswa, kumirisana nemasimba ekunze, kugovera kushushikana, uye kana simba rekunze rinoshandiswa richibvarura zvinhu, shinda inoungana pamwe nekutsemuka kwekutanga, ichiwedzera kuramba kubvarura.Kana warp yakarukwa inoumbwa ikashandiswa, shinda dzakarukwa dzinodzokororwa dzinodzokororwa pakati pemafiber layers ewarp, weft, uye geotextile, zvichiita kuti matatu acho arukwe kuita chimwe.Naizvozvo, warp yakarukwa composite geomembrane haina chete hunhu hwekusimba kwepamusoro uye kuderera kwerefu, asi zvakare ine kusapinda mvura kwegeomembrane.Naizvozvo, warp knitted composite geomembrane imhando yeanti-seepage zvinhu zvine mabasa ekusimbisa, kuzviparadzanisa nevamwe, uye kudzivirira.Iyo yakakwirira-yepamusoro inoshandiswa geosynthetic zvinhu munharaunda yepasirese nhasi.
Kusimba kwakasimba, kureba kwakadzika, yunifomu yakareba uye yakachinjika deformation, kukwirira kwemisodzi, kusakara kwakanakisa, uye kushorwa kwemvura kwakasimba.Iyo anti-seepage performance inonyanya kuenderana ne-anti-seepage kuita kwefirimu repurasitiki.Mafirimu epurasitiki anoshandiswa kudzivirira seepage kumba nekune dzimwe nyika anonyanya kusanganisira (PVC) polyethylene (PE) uye ethylene/vinyl acetate.copolymer (EVA), inova zvinhu zvinochinjika zvePolymer chemistry ine diki chaiyo giravhiti, kuwedzera kwakasimba, kuchinjika kwepamusoro kune deformation, corrosion resistance, kushoma tembiricha kuramba uye yakanaka chando kuramba.Hupenyu hwesevhisi yemubatanidzwa geomembrane inonyanya kutsanangurwa kana iyo firimu yepurasitiki yakarasikirwa ne-anti-seepage uye basa rekuparadzanisa kwemvura.Maererano nemitemo yenyika yeSoviet Union, firimu re polyethylene nehupamhi hwe 0.2m uye stabilizer inoshandiswa mu hydraulic engineering inogona kushanda kusvika kumakore 40-50 pasi pemvura yakachena uye makore 30-40 pasi pemamiriro emvura.Nokudaro, hupenyu hwebasa re geomembrane yakasanganiswa yakakwana kuti iite zvinopesana nezvinodiwa zvedhamu.
