High Impermeability High Corrosion Resistance Long Service Life Geomembrane For Landfills
Product Introduction
Smooth surface geomembrane is a widely used geosynthetic material, mainly made of high-density polyethylene (HDPE) material, with a smooth surface and no rough texture.
Product Properties
1. Impermeability: smooth geomembrane has excellent impermeability and can effectively prevent water penetration, which is suitable for various impermeability projects.
2. Chemical corrosion resistance: It has good chemical corrosion resistance and can resist the erosion of various chemical substances.
3. Environmental stress cracking resistance: With good environmental stress cracking resistance, can maintain stability in harsh environments.
4. Temperature adaptability: It has a large temperature range and can be used in high or low temperature environments.
5. Tensile strength: It has high tensile strength and elongation, and can withstand certain water pressure and adapt to foundation deformation.
6. Long service life: under proper use and maintenance, the service life of smooth geomembrane can be very long.
7. Convenient construction: smooth geomembrane is easy to lay, easy to construct, and can be connected by welding and other ways to form a continuous impermeable layer.
Product Application
It is widely used in the seepage prevention and isolation of landfill, tailings storage, channel seepage prevention, dam seepage prevention, subway project, artificial lake, reservoir and other projects.
