Geomembrane

Introduction to the standard of landfill geomembrane

2020-09-24
What is the standard thickness range of landfill geomembrane? The thickness of HDPE geomembrane can be 0.75mm, 1.0mm, 1.25mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, etc. According to the requirements of the national standard CJ/T234-2006, it should also be based on actual conditions.
The HDPE film thickness is recommended to be at least 1.5 mm, and the error should be within ±3%. According to the experience of the project so far, the landfill uses 1.5 and 2.0 at most. ?? Of course, if the geomembrane is used in different directions of the landfill, the choice of thickness will be different. Mainly used as anti-penetration, anti-oblique penetration and short-distance substrate.

Use different types of film in the same direction. For example, the smooth surface of the substrate or the inclined rough surface. In addition, there are many other factors in choosing the thickness, such as the topography and soil quality of the landfill. , Anti-permeable materials, anti-permeability requirements, etc. HDPE geomembrane has excellent resistance to environmental stress cracking performance, wide applicable temperature range (-60 to +60), long service life (50 years).
