How to choose a good geomembrane

Anhui Zhonglu tells you that the choice of HDPE geomembrane should be based on the design standards of the project and the needs of the site. If it is used in fish ponds, 0.5mm national standard and new geomembrane can be considered; if it is used in landfills, 1.0 and 1.0 are generally used. 1.5mm urban construction standard HDPE geomembrane.

1. High-quality geomembrane has a good appearance. The appearance of high-quality geomembrane is black, bright, smooth, and has no obvious material points, while the appearance of inferior geomembrane is black, rough, and has obvious material points.

2. High-quality geomembrane has good tear resistance, high-quality geomembrane is not easy to be torn and sticky when torn, while inferior geomembrane is easy to tear.

3. High-quality geomembrane has high flexibility, high-quality geomembrane feels hard and firm, bends elastically, has no obvious crease after repeated bending, and inferior geomembrane has poor bending flexibility and white crease at the bend, Bending multiple times is easy to break.

4. The high-quality geomembrane has good physical properties. The high-quality geomembrane can be stretched to more than 7 times its own length on the testing equipment without breaking, while the inferior geomembrane can only be stretched to 4 times its own length or even lower. , the rupture strength of high-quality geomembrane can reach 27MPa while the rupture strength of inferior geomembrane is lower than 17MPa.

5. High-quality geomembrane has good chemical properties, high-quality geomembrane has good acid and alkali resistance, corrosion resistance, aging resistance and UV resistance, while inferior geomembrane has acid and alkali resistance, corrosion resistance, aging resistance and UV resistance The performance is poor, and it will age and crack after being exposed for more than one year.

6. The high-quality geomembrane has a long service life. The high-quality geomembrane has a service life of more than 100 years underground and a service life of more than 5 years when exposed on the ground, while the underground service life of the inferior geomembrane is only 20 years. Exposure service life will not exceed 2 years.
