What is The Degree of Stretching of HDPE Geomembrane?
HDPE geomembrane has great tensile strength in both the longitudinal and transverse directions. It is suitable for the large-area permanent bearing foundation. The polymer is extruded into a thin plate and then punched into a regular hole net, and then longitudinally stretched. In this process, the polymer is oriented in a linear state and forms a long elliptical network-like monolithic structure with uniform distribution and high joint strength. The structure has a relatively high tensile strength and tensile modulus, tensile strength and The tensile modulus provides the soil with an ideal force for the burden and diffusion of the interlocking system. High strength, small creep, adapt to various types of environmental soil, can fully meet the use of high retaining walls in high-grade roads. It can effectively improve the interlocking and biting of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and enhance the stability of the foundation.
Because of the mesh structure, the aggregate in the asphalt concrete can penetrate therethrough, thus forming a mechanical interlock. This limitation hinders the movement of the aggregate, enabling the asphalt mixture to achieve a better compaction condition under load, higher load-bearing capacity, better load transfer performance, and less deformation. The HDPE geomembrane for sale is compacted with the dregs, and the relative displacement between the upper non-woven fabric and the dross produces friction so that the upper non-woven fabric is pulled, and the tensile deformation of the upper nonwoven fabric is caused between the geomembrane and the geomembrane below. The relative displacement, the frictional stress is transmitted between the layers of the liner system, and the creep damage may occur under the action of high stress for a long time. The tension of the end of the geomembrane also determines the size of the end anchor solid product.
