Smooth geomembrane
Tsanangudzo Pfupi
Iyo geomembrane yakatsetseka inowanzogadzirwa nechinhu chimwe chete chepolymer, senge polyethylene (PE), polyvinyl chloride (PVC), nezvimwewo.
Basic structure
Iyo geomembrane yakatsetseka inowanzogadzirwa nechinhu chimwe chete chepolymer, senge polyethylene (PE), polyvinyl chloride (PVC), nezvimwewo.
- Hunhu
- Yakanaka anti-seepage performance: Iyo ine yakanyanya kuderera permeability uye inogona kunyatso kudzivirira kupinda kwezvinwiwa. Iine yakanaka chipingamupinyi chinopesana nemvura, oiri, kemikari mhinduro, nezvimwewo. Iyo anti-seepage coefficient inogona kusvika 1×10⁻¹²cm/s kusvika 1×10⁻¹⁷cm/s, inogona kusangana nezvinodiwa zveanti-seepage zvemapurojekiti mazhinji. .
- Yakasimba kugadzikana kwemakemikari: Iyo ine yakanakisa asidhi uye alkali inodzivirira uye nekuora kwekudzivirira. Inogona kuramba yakagadzikana munzvimbo dzakasiyana dzemakemikari uye haisi nyore kuparadzwa nemakemikari ari muvhu. Inogona kuramba kuodzwa kwemamwe maratidziro easidhi, alkali, munyu uye mamwe mhinduro.
- Yakanaka yakaderera-tembiricha kuramba: Iyo inogona kuramba ichichengetedza yakanaka kuchinjika uye michina zvimiro munzvimbo yakaderera-yekushisa. Semuenzaniso, mamwe emhando yepamusoro polyethylene akatsetseka geomembranes achine imwe elasticity pa -60 ℃ kusvika -70 ℃ uye haisi nyore kuputsika.
- Kuvaka kwakaringana: Iyo yepamusoro inotsvedza uye friction coefficient idiki, iri nyore kuisa panzvimbo dzakasiyana siyana uye mabhesi. Inogona kubatanidzwa ne welding, bonding uye dzimwe nzira. Kumhanya kwekuvaka kunokurumidza uye kunaka kuri nyore kudzora.
Production Process
- Extrusion blow molding nzira: Iyo polymer mbishi zvinhu zvinopiswa kune yakanyungudutswa uye inoburitswa kuburikidza neextruder kuita tubular isina chinhu. Zvadaro, mweya wakatsikirirwa unopeperetswa muchubhu isina kuvharwa kuti iwedzere uye inobatirira kune mold yekutonhodza nekuumba. Pakupedzisira, iyo geomembrane yakatsetseka inowanikwa nekucheka. Iyo geomembrane inogadzirwa neiyi nzira ine yunifomu ukobvu uye yakanaka michina zvinhu.
- Calendering nzira: Iyo polymer mbishi zvinhu zvinodziiswa uye zvobva zvawedzerwa uye zvakatambanudzwa nema roller akawanda ekarenda kuti iite firimu rine humwe ukobvu nehupamhi. Mushure mekutonhora, iyo geomembrane yakatsetseka inowanikwa. Iyi nzira ine hunyanzvi hwekugadzira uye hupamhi hwechigadzirwa, asi ukobvu hwakafanana hushoma.
Minda Yekushandisa
- Mvura yekuchengetedza purojekiti: Inoshandiswa pakurapa-kupenya kwenzvimbo dzekuchengetedza mvura senge madhamu, madhamu, uye migero. Inogona kudzivirira kudonha kwemvura nemazvo, kuvandudza machengeterwo emvura uye kufambiswa zvakanaka kwemapurojekiti ekuchengetedza mvura, uye kuwedzera hupenyu hwebasa reprojekiti.
- Kurashira marara: Seye anti-seepage liner pazasi nepadivi peraswa, inodzivirira leachate kubva pakusvibisa ivhu nemvura yepasi uye inodzivirira zvakatenderedza nharaunda.
- Kuvaka kusapinda kwemvura: Inoshandiswa seyakagadzika mvura padenga, pasi, imba yekugezera uye zvimwe zvikamu zvechivako kudzivirira kupinda kwemvura inonaya, mvura yepasi uye humwe hunyoro muchivako uye kuvandudza kusapinda kwemvura kwechivako.
- Artificial landscape: Inoshandiswa kune anti-seepage yemadziva ekugadzira, madziva enzvimbo, nzvimbo dzegorofu dzemvura, nezvimwewo, kuchengetedza kugadzikana kwemuviri wemvura, kuderedza kudonha kwemvura, uye nekupa hwaro hwakanaka hwekusikwa kwenzvimbo.
Zvinotsanangurwa uye Technical Indicators
- Zvinotsanangurwa: Ukobvu hweiyo geomembrane yakatsetseka kazhinji iri pakati pe0.2mm ne3.0mm, uye hupamhi hunowanzo kuve pakati pe1m ne8m, iyo inogona kugadzirwa zvinoenderana nezvinodiwa zvemapurojekiti akasiyana.
- Tekinoroji zviratidzo: Kusanganisira kusimba kwesimba, kurebesa panguva yekuzorora, kurudyi-kona kubvarura simba, hydrostatic pressure resistance, etc. Iyo tensile simba rinowanzova pakati pe5MPa ne30MPa, kureba panguva yekuzorora kuri pakati pe300% ne1000%, the right-angle kubvarura. simba riri pakati pe50N/mm ne300N/mm, uye hydrostatic pressure resistance iri pakati pe0.5MPa ne 3.0MPa.
