Geomembrane yog cov khoom siv geomembrane tsim los ntawm cov yas zaj duab xis raws li cov khoom siv tsis zoo thiab cov ntaub tsis muaj ntaub.Lub impervious kev ua tau zoo ntawm cov khoom tshiab geomembrane tsuas yog nyob ntawm qhov kev ua tau zoo ntawm cov yas zaj duab xis.Cov yeeb yaj kiab yas siv los tiv thaiv kev nkag mus hauv tsev thiab txawv teb chaws feem ntau suav nrog polyvinyl chloride (PVC), polyethylene (PE), thiab EVA (ethylene / vinyl acetate copolymer).Hauv kev siv qhov av, kuj tseem muaj cov qauv tsim uas siv ECB (ethylene acetate hloov asphalt blend geomembrane).Lawv yog cov khoom siv hluav taws xob hloov pauv cov ntaub ntawv polymer nrog lub ntiajteb txawj nqus me me, muaj zog extensibility, siab deformation tsis kam, corrosion kuj, tsis kub tsis kam, thiab zoo te.
Geomembrane yog cov khoom tsis muaj dej tsis zoo thiab cov khoom thaiv raws li polymer.
Nws feem ntau muab faib ua: low density polyethylene (LDPE) geomembrane, high density polyethylene (HDPE) geomembrane, thiab EVA geomembrane.
1. Qhov dav thiab thickness specifications tiav.
2. Nws muaj ib puag ncig kev nyuaj siab tawg ua hauj lwm thiab zoo heev tshuaj corrosion kuj.
3. Cov tshuaj tiv thaiv corrosion zoo heev.
4. Nws muaj kev ua haujlwm kub ntau thiab ua haujlwm ntev.
5. Siv rau hauv qhov chaw pov tseg, qhov chaw cia khoom tailings, tiv thaiv kwj dej seepage, embankment seepage tiv thaiv, thiab subway tej yaam num.
Nws lub luag haujlwm tseem ceeb yog cais cov dej ntws tawm ntawm lub ntiaj teb lub pas dej nrog lub impermeability ntawm cov yas zaj duab xis, tiv taus dej siab thiab hloov mus rau qhov deformation ntawm lub pas dej da dej nrog nws lub zog tensile loj thiab elongation;Cov ntaub tsis woven kuj yog ib yam ntawm cov khoom siv luv luv polymer fiber ntau, uas yog tsim los ntawm rab koob punching lossis thermal bonding, thiab muaj zog tensile thiab extensibility.Thaum ua ke nrog cov yas zaj duab xis, nws tsis tsuas yog ua kom lub zog tensile thiab puncture tsis kam ntawm cov yas zaj duab xis, tab sis kuj ua rau kom muaj kev sib txhuam coefficient ntawm kev sib cuag nto vim qhov ntxhib saum npoo ntawm cov ntaub tsis woven, uas yog qhov zoo rau kev ruaj ntseg ntawm cov khoom sib xyaw. geomembrane thiab txheej tiv thaiv.Nyob rau tib lub sijhawm, lawv muaj kev tiv thaiv corrosion zoo rau cov kab mob thiab tshuaj lom neeg, tsis ntshai cov kua qaub, alkali, thiab ntsev yaig, thiab muaj lub neej ua haujlwm ntev thaum siv hauv qhov chaw tsaus.
