Characteristics of Anti-seepage Geomembrane
What are the characteristics of the anti-seepage geomembrane?
1. High anti-seepage coefficient
The anti-seepage geomembrane has the anti-seepage effect unmatched by common waterproof materials. The HDPE anti-seepage film has high tensile and mechanical resistance, and its excellent elasticity and deformability make it very suitable for expanding or shrinking the base surface, which can effectively overcome the base surface. Uneven settlement, high water vapor permeability coefficient
2. Chemical stability
The anti-seepage geomembrane has excellent chemical stability and is widely used in sewage treatment, chemical reaction tanks, and landfills. High-temperature resistance, asphalt resistance, oil and tar resistance, acid, alkali, salt and other strong acid and alkali chemical media corrosion
3. Aging resistance
The anti-seepage geomembrane has excellent anti-aging, anti-ultraviolet and anti-decomposition ability can be used barely, and the service life of the material is 50-70 years, which provides a good material guarantee for environmental anti-seepage.
4. Resistance to plant roots
HDPE anti-seepage membrane has excellent puncture resistance and can resist most plant roots
5. High mechanical strength
The anti-seepage geomembrane has good mechanical strength, tensile strength at break of 28 MPa, and elongation at break of 700%.
6. Low cost and high efficiency
HDPE anti-seepage film adopts new technology to improve the anti-seepage effect, but the production process is more scientific and quick, so the production cost is lower than the traditional waterproof material. The actual project using HDPE anti-seepage film has to save about 50% of the cost.
7. Construction speed is fast
The anti-seepage geomembrane has high flexibility and has various specifications and various laying forms to meet different engineering anti-seepage requirements. It adopts hot-melt welding, high weld strength, convenient construction, fast and healthy.
8. Environmentally friendly and non-toxic
The materials used in the anti-seepage geomembrane are non-toxic and environmentally friendly materials. The anti-seepage principle is a common physical change and does not produce any harmful substances. It is the best choice for environmental protection, breeding, and drinking water pools.
