Polyethylene geomembrane material has the following performance characteristics:
1.Excellent anti-seepage performance: The anti-seepage coefficient of polyethylene geomembrane is very low, which can effectively prevent the passage of water and other liquids, and is suitable for anti-seepage treatment in many fields such as water conservancy, environmental protection, municipal, transportation, and aquaculture.
2.Strong weather resistance: It has good heat resistance and cold resistance, and can maintain stable physical and mechanical properties in a wide range of temperatures (such as high temperature 110, low temperature -70).
3.Good chemical stability: It has strong corrosion resistance to acids, alkalis, salts, etc., so it can be used for a long time in an environment containing chemicals without damage.
4.High mechanical strength: It has high tensile strength and elongation at break, and can withstand the tension and stress during construction, as well as the foundation deformation that may occur during subsequent use.
5.Aging resistance: After special formulation and production process treatment, polyethylene geomembrane has good UV resistance and durability, and can maintain its anti-seepage effect even if it is exposed to nature for a long time.
6.Excellent welding performance: different sheets can be welded to form a continuous whole by hot melt welding, ensuring the integrity of the entire anti-seepage system.
Based on the above characteristics, polyethylene geomembrane is widely used in landfill seepage prevention system, tailings pond seepage prevention, artificial lake and landscape pool construction, water conservancy projects such as channel and reservoir seepage prevention, and agricultural irrigation system water source protection. According to the different raw materials, polyethylene geomembrane can be divided into LDPE (low density polyethylene), LLDPE (linear low density polyethylene) and HDPE (high density polyethylene) and other types to meet the needs of different projects.
