What are the advantages of using black green dual color geomembrane for landfill cover
Black green geomembrane, also known as black green dual color HDPE geomembrane, is a new type of geomembrane with one side black and the other side green. It is widely used for covering landfill sites and tailings dams.
Black green geomembrane is generally produced by three-layer co extrusion blow molding of high-density polyethylene particles (HDPE). Black green geomembrane is mainly used in the sealing and covering construction of landfills. The black green dual color geomembrane not only has good anti-seepage effect, but also has high puncture resistance and strong tensile strength.
Below, we will provide a detailed introduction to the advantages of black green dual color geomembranes.
At present, there are many specifications of black green geomembranes on the market, with thicknesses ranging from 0.2mm to 2.0mm. So, how should we choose black green geomembranes? Which thickness of black green geomembrane is more suitable for selection?
Black green geomembrane in production
One is good material quality: The green side of the black green dual color geomembrane requires high raw material quality, and only good raw materials can produce a green side. Recycled materials with mixed materials and inconsistent colors cannot produce black green dual color geomembranes. Therefore, the production of black green dual color geomembranes must use new or white materials.
2, Good quality: The black green dual color geomembrane can only be produced using brand new or white materials, and good raw materials ensure the product quality of the black dual color geomembrane. Therefore, the quality of the black green dual color geomembrane is generally higher than or equal to that of the same specification of black geomembrane. Black green dual color geomembrane generally follows urban construction standards.
Third, good appearance: the black green double color geomembrane is smooth and shiny without obvious material points. The black green double color geomembrane not only has good sun resistance and aging resistance, but also has beautiful green surface. Therefore, the black green double color geomembrane is often used for covering and sealing landfill sites
Fourth, long service life: as we all know, the black geomembrane has good anti-aging and sun resistance, but because of the heat absorption characteristics, the service life of the black geomembrane will also be affected. The green surface also reduces the heat absorption capacity of the geomembrane, greatly extending the service life of the geomembrane.
