Because the composite geomembrane has oxidation resistance, some files in some companies extend the time limit the previous Soviet Union BCH07-74 "Notice for the earth-rockfill application of polyethylene dam seepage control structure" stipulates polyethylene geomembrane can be used for buildings with limit over 50 Ollie Linz company publish papers on polypropylene composite geo-membrane geotechnique composite material character, whose conclusion is: Polypropylene 15 on-site application experience shows that the compound has high stability; fabric damage construction; laying has no change;...... Expected to exceed 100 stability diagram"
Geotechnical membrane is a kind of geotechnical material which is membrane-shaped and has low water?permeability, used in civil engineering. Classification of geomembrane: geomembrane is generally divided into asphalt geomembrane and polymer (synthetic polymer) geomembrane two major types. In order to meet the needs of different strength and deformation in civil engineering applications, the two types of geomembrane are evolved into combination types of reinforced and non-reinforced (single or mixed). 1. The asphalt geomembrane is mainly composite geomembrane at present (including woven or non-woven geotextile) with asphalt as infiltration binder. 2, The polymer geomembrane can be divided into plastic geomembrane, elastic geomembrane and composite geomembrane (composite geomembrane) according to different main materials, in which the main material of plastic geomembrane include: Polyvinyl chloride (PVC), durable polyvinyl chloride (PVC-OR), toughened polyvinyl chloride (PVC-E), chlorinated polyethylene (CPE), low density polyethylene (LDPE), medium density polyethylene (MDPE), high density polyethylene (HDPE), toughened polyolefin or elastic polyolefin (ELPO) The main material of elastic geomembrane is rubber... Geomembrane is akind of membrane-shaped geotextile material with very low permeability, which is used in civil construction engineering. Classification of geomembrane: geomembrane is generally divided into asphalt geomembrane and polymer (synthetic polymer) geomembrane two major types. In order to meet the needs of different strength and deformation in civil engineering applications, the two types of geomembrane are evolved into combination types of reinforced and non-reinforced (single or mixed).
