Product introduction: Nitrogen filled (single/double) rough surface HDPE geomembrane. Nitrogen is directly mixed with HDPE geomembrane raw materials and then enters different channels of the multi-layer co extrusion die together with ordinary layer geomembrane raw materials for co extrusion molding.

Product specifications: Thickness of 0.1~3.0mm, width of 4~10m, length according to engineering design and customer requirements.

Product features: The friction performance of the geomembrane surface is improved, and the tensile resistance is stronger compared with the smooth facial mask of the same specification. The surface of the rough facial mask is rough and textured. When laying the film, it will form a micro void layer between the film and the base surface, greatly enhancing the anti bearing capacity of the geomembrane.

Application scope: Municipal environmental protection engineering, landfill treatment engineering, sewage treatment engineering, anti-seepage and anti-corrosion engineering in the metallurgical and petrochemical industries, anti-seepage and anti fouling engineering in the petrochemical industry, tailings treatment, anti-seepage and anti fouling engineering in red mud piles, anti-seepage and anti fouling engineering in power plant ash dams, etc.

Product execution standards: GB/T17643-2011 (GH-2T1 type, GH-2T2 type) "Geosynthetic polyethylene geomembrane", CJ/T234-2006 "High density polyethylene geomembrane for landfill sites", GRI-GM 13 current American standard
