Geomembrane For Impermeability Of Reservoir And Artificial Lake
Product Introduction
Smooth geomembrane is a type of geomaterial with a smooth surface, usually made of high-density polyethylene, which has excellent chemical resistance and environmental stress cracking resistance. It is mainly used for seepage prevention and isolation.
Product Properties
1. Impermeability: The impermeability coefficient of the smooth geomembrane is very high, which can effectively prevent the penetration of water and pollutants.
2. Chemical resistance: It can resist the attack of many chemical substances, including acids, bases and salts.
3. Resistance to environmental stress cracking: it can remain stable in harsh environments such as ultraviolet light and temperature changes.
4. Tensile strength: It has high tensile strength and elongation, and can withstand certain water pressure and adapt to foundation deformation.
Product Application
1. Landfill: Used as an impermeable layer to prevent contaminants from seeping into groundwater.
2. Tailings storage yard: prevent harmful substances in tailings from penetrating into the environment.
3. Channel seepage prevention: used in agricultural irrigation channels to reduce water loss.
4. Dam anti-seepage: enhance the anti-seepage capacity of the dam to prevent water penetration.
5. Subway engineering: waterproof layer for subway tunnels.
6. Artificial lakes and reservoirs: as impermeable layers, maintain the stability of water bodies.
