How does Composite geomembrane prevent aging?

      For composite geomembrane, composite geomembrane aging is one of the inherent characteristics of polymer materials. Although it cannot be completely eliminated, effective measures can be taken to delay the aging phenomenon of Composite geomembrane.

       The measure to delay the aging of Composite geomembrane is to add anti-aging agents to the raw materials, which will inhibit the effect of light, oxygen, heat and other external factors on the materials. For example, the proper amount of antioxidants, light stabilizers and dark carbon black are mixed. Some units add an anti-aging agent to polypropylene. After 4 years of direct sunlight, the strength is only lost by 25%. If the anti-aging agent is not added, it is directly exposed to sunlight for 2 to 3 months. , The strength is about to be lost.

       Therefore, our factory will do a good job of anti-ultraviolet protection during production. That is to say, anti-aging and anti-ultraviolet additives will be added during production. The purpose of this is to delay its aging and extend the service life of Composite geomembrane.

       In fact, according to statistics, composite geomembrane can reach 40 to 50 years in a clean water environment even when it is not exposed to the sun, but in a water-free environment, its service life can also reach three. Forty years, the service life of Composite geomembrane is very long, but its service life will be shortened due to aging.

      Composite geomembrane has good heat resistance and cold resistance. The ambient temperature of its use can be maintained at 110 degrees Celsius at high temperatures, and can be maintained at minus 70 degrees Celsius at low temperatures. Composite geomembrane has good chemical stability and can resist strong acids and alkalis. It is a very good anti-corrosion material.
      
      Because the composite geomembrane has excellent characteristics, it can be used not only for water barriers, but also for the construction of drainage facilities, bringing great convenience to people's lives. Its good and uniform tear resistance, enhanced abrasion resistance and water resistance have not only increased its use in various environments, so to sum up, Composite geomembrane has relatively stable chemical properties, whether it is salt or acid. Alkali will not react chemically.

       This will neither cause damage to the medium nor affect the integrity of the Composite geomembrane, so this composite geomembrane can be used in any environment.
