Geomembrane The criteria for judging high-quality geomembrane mainly include appearance quality, physical properties, chemical properties and service life.
Appearance quality of geomembrane ：A high-quality geomembrane should have a smooth surface, uniform color, and no obvious bubbles, cracks or impurities. Flat appearance, no obvious scratches or spots, uniform color, no wavy or bumpy places 。
Physical properties of geomembrane ：High-quality geomembrane should have high tensile strength and ductility, and be able to withstand a certain tensile force without breaking easily. In addition, it should have good tear resistance, puncture strength and impact resistance 。
Chemical properties of geomembrane ：High-quality geomembrane should have good acid and alkali resistance, corrosion resistance, aging resistance and UV resistance to ensure stable performance under various environmental conditions 3。
Geomembrane service life ：The service life of high-quality geomembrane can reach more than 50 years underground and more than 5 years above ground exposure, while the service life of inferior geomembrane is only 5 years underground and not more than 1 year above ground exposure 。
In addition, checking the test report of geomembrane is also an important basis for judging its quality. High-quality geomembranes should be tested by authoritative organizations and meet relevant national or industry standards 。The quality of geomembrane can be judged comprehensively by comprehensively using the methods of observation, stretching, smelling and burning 。
