High density polyethylene geomembrane for landfill CJ/T234-2006

High density polyethylene geomembrane for landfill cj/t234-2006

The standard specifies three types of geomembrane,

1: HDPE geomembrane hdpe1

2: HDPE geomembrane hdpe2-1 on single rough surface

3: HDPE geomembrane hdpe2-2 with double roughness surface

The standard specifies that the technical index of HDPE geomembrane with smooth surface is

1: Yield elongation ≥ 12%

2: Elongation at break ≥ 700%

3: Resistance to environmental stress cracking ≥ 300h

The standard specifies that the technical index of HDPE geomembrane with rough surface is

1: Yield elongation ≥ 12%

2: Elongation at break ≥ 100%
