Black And Green Dual-Color HDPE Smooth Geomembrane For Environmental Protection
Product Introduction
The black and green dual-color HDPE geomembrane is a new type of impervious geosynthetic material that combines the excellent properties of high-density polyethylene (HDPE) with the advantages of a dual-color design.The black and green double-color HDPE geomembrane usually has one side black and the other side green. With the black side facing down, it can prevent rainwater from seeping in, increase the service life, and reduce the cost of leachate treatment. The green side facing up has the characteristics of environmental protection and aesthetics, while reducing the heat absorption ability of the geomembrane and prolonging the service life.
Product Properties
♦ Excellent chemical resistance (corrosion resistance);
♦ Outstanding stress cracking resistance (environmental stress cracking resistance);
♦ Lowest permeability;
♦ Excellent UV resistance;
♦ Stable resistance to low temperature embrittlement;
Product Application
The black and green dual-color HDPE geomembrane is widely used in various fields due to its excellent performance.
1. Water Conservancy Projects
In channel seepage control projects, black and green dual-colored HDPE geomembrane is used as a geosynthetic material to provide an efficient seepage control solution. It is widely used in canal transformation, artificial lake, and water conservancy construction projects.
2. Landfill
This geomembrane is particularly suitable for covering and final capping of landfills. The green side's environmental protection characteristics make it an ideal choice for landfills.
3. Environmental Engineering Projects
Due to its chemical resistance and aging resistance properties, the black-green double-color HDPE geomembrane is also used in sewage treatment plants, chemical reaction pools, and other environmental protection projects.
