HDPE Geomembrane Description
(1)Introduction: HDPE geomembrane is produced from high density polyethylene resin by film-blowing process, adding carbon black, antioxidant, anti-aging and UV-resistance component. Now it is the most widely used products for solid waste containment (such as landfill liners), mining and water containment applications. (2)Specification: 1. Thickness: smooth surface 0.2mm - 3.0mm, textured surface 1.0-2.0mm 2. Width: smooth surface 1m-8m, rough surface 4m-8m 3. Length: 50m-200m/ roll or as requested. 4. Material: HDPE, LDPE, LLDPE 5. Color: black, white, blue, green. 6. Optional surface: smooth surface, single surface textured, dual surfaces textured. 7. Certificates: CE, ISO9001, ISO14001.Parameters Of HDPE Liner
Application Of HDPE Liner
1.Environmental protection projects: Anti-seepage project on garbage landfills, sewage treatment plants, power plant regulating tanks, underground foundation waterproof and anti-seepage, factory roof moisture-proof industries, hospital solid waste etc. 2.Aquaculture industry: Anti-seepage project on aquaculture ponds, intensive and factory farming ponds, fish ponds, lining of shrimp ponds, sea cucumber ring slope protection, etc. 3.Agriculture project: Anti-seepage project on reservoir, drinking water pond, impoundment pond, irrigation system seepage prevention, agricultural breeding such as pig farm septic tank etc. 4.Chemical mining industry: Anti-seepage project on the bottom lining of ash slag field, red mud pile, heap leaching tank, dissolution tank, sedimentation tank, and tailings dam etc. 5.Construction projects: Anti-seepage project on subway, underground garage, roof garden, sewage pipe, and drainage box etc.Length: 20-200m (customized) Color: black/white/transparent/green/blue/customized
