What is The Durability of HDPE Impermeable Membrane?
HDPE impermeable membranes tend to be strongly affected by the surrounding environment due to the strong properties of the polymer, and often contact with harmful toxic liquids and gases for a long time. Research methods and evaluation indicators are also the problems to be determined in durability research.
Crystalline polymer high quality aquaculture geomembrane (such as HDPE) are not susceptible to aging. Therefore, the study of their service life is a basic problem. Non-crystalline thermoplastic polymers such as PVC are susceptible to aging.
HDPE anti-seepage membrane has high expansion and high water absorption capacity and has low water permeability when wet. The position and structure of the floor layer of HDPE anti-seepage film material is 1:3 cement mortar leveling layer.
The permanent protective wall dial is made of 1:3 cement mortar for screeding, and the HDPE impermeable membrane permanent protective wall dial is made of 1:3 cement mortar for screeding. The water permeability during wetting is mainly due to the excellent quality of the anti-seepage effect.
