1.High-quality geomembrane has a good appearance. High-quality geomembrane has a black, bright and smooth appearance with no obvious material spots, while inferior geomembrane has a black, rough appearance with obvious material spots.
2.High-quality geomembrane has good tear resistance, high-quality geomembrane is not easy to tear and sticky when tearing, while inferior geomembrane is easy to tear.
3.High-quality geomembrane has high flexibility. High-quality geomembrane feels hard, is elastic in bending, and has no obvious creases after multiple bending, while inferior geomembrane has poor bending elasticity and has white creases at the bending, which is easy to break after multiple bending.
4.High-quality geomembrane has good physical properties. High-quality geomembrane can be stretched to more than 7 times its own length without breaking on testing equipment, while inferior geomembrane can only be stretched to 4 times or even lower its own length. High-quality geomembrane The breaking strength of geomembrane can reach 27 MPa The fracture strength of inferior geomembrane is lower than 17 MPa。
5.High-quality geomembrane has good chemical properties. High-quality geomembrane has good acid and alkali resistance, corrosion resistance, aging resistance and ultraviolet resistance, while inferior geomembrane has poor acid and alkali resistance, corrosion resistance, aging resistance and ultraviolet resistance, and will age and crack after exposure for more than one year.
6.High-quality geomembrane has a high service life. The service life of high-quality geomembrane can reach more than 100 years underground and more than 5 years when exposed above ground, while the service life of inferior geomembrane is only 20 years underground and will not exceed 2 years when exposed above ground.
