Characteristic: Geomembrane has a good anti-aging properties; Water resistance, corrosion resistance, high strength, wear resistance, low temperature, non-toxic, good surface drainage, seepage good effect; Has a unique thermal insulation, moisture, frosting, frost effect.
Use: Widely used in dams, roads, airports, drainage, housing, environmental protection and other fields;
Unit: square meter
Product Overview: By geotextile composite geomembrane (or fiberglass mesh), Polymer materials (such as PE film, EVA film), Composite material made of two or more of geosynthetics. It is hydraulic conductivity of geotextile layer, impervious layer of polymer material by rolling or casting, hot melt coating formed.
Product Structure: one-geotextile one- membrane type, ,one-geotextile two-membrane type ,two-geotextile one-membrane type,two-geotextile two-membrane type,several-geotextile several-membrane.etc.
Fabric type: Filament geotextile, short silk geotextile, woven geotextile; Membrane (polymer composite materials); high-density polyethylene (HDPE), low pressure polyethylene (LDPE) and so on.
Product Characteristic: Width up to 6.5 meters, compared with the narrow range of similar products, reducing splicing to speed up the construction progress, but also reduced due to joints caused by improper handling risks;
Use of composite geomembrane with the traditional cloth, the use of membrane separation, compared to increase the stability of the product, but also saves engineering time, reduce project costs, the overall efficiency significantly; Using buried laying, long durability, good anti-aging properties; Water resistance, corrosion resistance, high strength, wear resistance, low temperature, non-toxic, good surface drainage, seepage good effect; Has a unique thermal insulation, moisture, frosting, frost effect.
Product Use : can be widely used in dams, roads, airports, drainage, housing, environmental protection and other fields.

Note 1: Actual Size (nominal breaking strength) between the table between adjacent specifications, calculated by linear interpolation the corresponding evaluation indicators; beyond the scope of the table, the evaluation index by the supply and demand sides through consultation. Note 2: Section 5, such as determination of when the sample is difficult to peel or not yet reached the provisions of the substrate or membrane rupture the peel strength, as to meet the requirements. Note 3: the first seven standard values by design or agreement. Note 4: The actual breaking strength less than the standard intensity, the standard intensity of the corresponding elongation is not for compliance determination. | |||||||||
