HDPE geomembrane products have strong anti-aging properties

The significance of the high-density hdpe geomembrane to resist environmental stress cracking is to use elastic basic theory and viscoelastic model to clearly propose a test standard for temperature stress and temperature stress relaxation.

In the experimental process, the tension and compression sensor, thermocouple and displacement gauge were used to discuss the damage of the high-density HDPE geomembrane to the resistance to environmental stress cracking and the change trend of the high-density hdpe geomembrane temperature stress with time. The experiment shows that the temperature stress of the high-density hdpe geomembrane changes with the change of the ambient temperature. When the ambient temperature decreases, the high-density hdpe geomembrane will decrease and cause temperature stress. After 1,500 hours in the laboratory, the high-density hdpe geomembrane's environmental stress cracking resistance index value can exceed 80% of the base material. I heard that the high-density HDPE geomembrane products have strong anti-aging properties.

However, the high-density hdpe geomembrane's anti-aging goal is closely related to the carbon black, anti-aging agent and anti-ultraviolet agent added during processing. The product quality is based on the ASTM test specifications of the United States and fully complies with the requirements of the US GRI-GM13 and national regulations.
