Double-rough-surface three-layer co-extrusion geomembrane
The invention relates to the technical field of geosynthetic materials, in particular to a geomembrane. A double-rough-surface three-layer co-extrusion geomembrane comprises an upper surface layer, a lower surface layer and a core layer arranged between the upper surface layer and the lower surface layer, the upper surface layer and the lower surface layer are anti-skid permeable layers, anti-skid protrusions are arranged on the outer side of the upper surface layer and the outer side of the lower surface layer, the anti-skid protrusions are made of polyethylene materials, and the thickness of the anti-skid protrusions is larger than that of the core layer. After hot melting, spraying and adhering to the outer sides of the upper surface layer and the lower surface layer. According to the double-rough-surface three-layer co-extrusion geomembrane provided by the invention, a spraying secondary roughening process is adopted for the membrane, and the rough surface of the geomembrane is formed by spraying coarse particles on the surface of the smooth-surface geomembrane, so that the physical, mechanical and thermal properties of the smooth-surface membrane are reserved to the maximum extent, and the overall performance is higher.
本发明涉及土工合成材料技术领域，特别涉及一种土工膜。一种双糙面三层共挤土工膜，包括上表层、下表层，以及设置于上表层和下表层之间的核心层，所述上表层和下表层均为防滑渗透层，在所述上表层和下表层外侧设置有防滑凸起，所述防滑凸起材质为聚乙烯材料，通过热熔后喷射附着于上表层、下表层外侧。本发明提供一种双糙面三层共挤土工膜，膜采用喷着二次加糙工艺，通过在光面土工膜表面喷射粗颗粒形成土工膜的粗糙表面，所以最大程度上保留了光面膜的物理、力学、热学性能，整体性能更高。
