Geomembrane chinhu che geomembrane chinoumbwa nefirimu repurasitiki sechinhu chisingapindire substrate uye jira risiri rakarukwa.Kuita kusingapindiki kwechinhu chitsva geomembrane kunonyanya kuenderana nekusapindirana kwekuita kwefirimu repurasitiki.Mafirimu epurasitiki anoshandiswa kudzivirira kubuda kwemvura kumba nekune dzimwe nyika anonyanya kusanganisira polyvinyl chloride (PVC), polyethylene (PE), uye EVA (ethylene/vinyl acetate copolymer).Mune tunnel applications, kune zvakare madhizaini anoshandisa ECB (ethylene acetate modified asphalt blend geomembrane).Iwo mapolymer makemikari anochinjika zvinhu ane diki chaiyo giravhiti, kuwedzera kwakasimba, yakakwirira deformation kuramba, corrosion resistance, yakaderera tembiricha kuramba, uye yakanaka chando kuramba.
Geomembrane chinhu chisingapindi mvura uye chinodzivirira chakavakirwa papolymer.
Iyo inonyanya kukamurwa kuita: low density polyethylene (LDPE) geomembrane, yakakwirira density polyethylene (HDPE) geomembrane, uye EVA geomembrane.
1. The hupamhi uye ukobvu tsanangudzo zvakakwana.
2. Iine yakanakisa kwezvakatipoteredza kusagadzikana kutsemuka kuramba uye yakanakisa kemikari corrosion resistance.
3. Yakanakisa makemikari ngura kuramba.
4. Iine hukuru hwekushanda kwekushisa uye hupenyu hurefu hwebasa.
5. Inoshandiswa munzvimbo dzekurasira marara, nzvimbo dzekuchengetera miswe, kudzivirira kwe canal seepage, ebankment seepage kudzivirira, uye mapurojekiti epasi pevhu.
Nzira yaro huru ndeyekuparadzanisa nzira yekuvuza yedhamu repasi nekusamira kwefirimu repurasitiki, kushingirira kumanikidzwa kwemvura uye kuchinjika kune deformation yemuviri wedhamu nesimba rayo rakakura uye kureba;Machira asina kurukwa imhando yepfupi polymer fiber kemikari makemikari zvinhu, iyo inogadzirwa nekubaya tsono kana kupisa kwekubatana, uye ine yakakwirira tensile simba uye kuwedzera.Kana yakasanganiswa nefirimu repurasitiki, haingowedzere simba rekusimba uye kuramba kwepurasitiki firimu, asi zvakare inowedzera friction coefficient yenzvimbo yekusangana nekuda kwekushata kwejira risiri rakarukwa, rinoita kuti kugadzikana kweiyo composite. geomembrane uye inodzivirira layer.Panguva imwecheteyo, vane kunaka kwekusagadzikana kwebhakitiriya uye chiito chemakemikari, havatyi asidi, alkali, uye kunyura kwemunyu, uye vane hupenyu hurefu hwebasa kana vakashandiswa munzvimbo ine rima.
