2024-09-29
As a composite material that combines the advantages of geotextiles and geomembranes, composite geomembrane has many advantages and strengths. Taking into account economic and environmental benefits, composite geomembrane is a cost-effective engineering material. Its many advantages have made it widely used and promoted in many fields.
1. Excellent anti-seepage performance
- High anti-seepage coefficient: composite geomembrane has an anti-seepage effect that ordinary waterproof materials cannot match, and has high tensile mechanical properties. Its excellent elasticity and deformation ability make it very suitable for expanding or shrinking base surfaces.
- Chemical stability: composite geomembrane can resist a variety of chemical substances, including corrosive substances such as acids and alkalis, so it is widely used in sewage treatment, chemical reaction pools, landfills and other environments.
2. Aging and UV resistance
- Aging resistance: composite geomembrane has anti-aging, anti-ultraviolet, and anti-decomposition capabilities, can be used exposed, and the material service life is up to 50 to 70 years, providing a good material guarantee for environmental anti-seepage.
3. Excellent physical and mechanical properties
- High mechanical strength: composite geomembrane has good mechanical strength, high tensile strength at break, large elongation at break, and can resist various external forces.
- Strong crack resistance: It has excellent resistance to environmental stress cracking and adapts to various complex environments.
4. Convenient and economical construction
- Fast construction speed: composite geomembrane has high flexibility, with various specifications and laying forms to meet the anti-seepage requirements of different projects, and adopts hot-melt welding, with high weld strength, convenient and fast construction.
- High cost-effectiveness: Although composite geomembrane uses emerging technologies to improve the anti-seepage effect, the production process is more scientific and fast, so the product cost is lower than that of traditional waterproof materials. According to actual calculations, general projects using composite geomembranes can save about 50% of costs.
5. Environmental protection and safety
- Environmentally friendly and non-toxic: The materials used in composite geomembranes are all non-toxic and environmentally friendly materials. The anti-seepage principle is ordinary physical changes, and no harmful substances are produced. It is the best choice for environmental protection, aquaculture, and drinking water pools.
6. Wide range of application fields
Composite geomembranes are widely used in water conservancy, municipal administration, construction, transportation, subway, tunnel, environmental protection, aquaculture, petrochemical, mining, salt industry, agriculture and other fields to meet various civil engineering needs such as anti-seepage, isolation, reinforcement, anti-cracking reinforcement, etc.
