HDPE Smooth Geomembrane for Landfill Water Treatment Mining and More Long Service Life Excellent Performanc
Product Introduction
HDPE Geomembrane, full name High Density Polyethylene Geomembrane, is a waterproof and barrier material produced from high density polyethylene resin. It has excellent resistance to environmental stress cracking, low temperature resistance, aging resistance, corrosion resistance, as well as a wide range of operating temperatures (-60°C to +60°C) and a long service life (up to 50 years). HDPE geomembranes are mainly used for impervious projects such as landfill site seepage prevention, sewage treatment plant seepage prevention, artificial lake seepage prevention, tailings treatment, etc.
The characteristics of HDPE geomembrane
The main characteristics of HDPE geomembrane include:
-
Resistance to Environmental Stress Cracking: Able to withstand various stresses in the environment and is not prone to cracking.
-
Low-temperature resistance: Maintains good performance even in low-temperature environments.
-
Corrosion Resistance: Offers good resistance to most household and industrial chemicals.
-
Wide Temperature Range: Can be used normally within the temperature range of -60 to +60°C.
-
Long service life: Due to its excellent performance, the service life of HDPE geomembrane can reach more than 50 years.
The Application of HDPE Geomembrane
HDPE geomembranes are widely used in various fields due to their excellent performance, mainly including:
-
Landfill Liner: Prevents leachate from landfills from polluting groundwater.
-
Wastewater Treatment Plant Imperviousness: Preventing wastewater from seeping into the ground and causing environmental pollution.
-
Artificial Lake Waterproofing: Ensuring the water quality of artificial lakes and preventing water loss.
-
Tailings Treatment : Prevent leakage of harmful substances and protect the environment.
