1.Material composition
EVA geomembrane: Made of ethylene-vinyl acetate copolymer (EVA), this material has good flexibility, flexibility, elasticity, weather resistance, environmental stress cracking resistance and bonding properties. Antioxidants, UV absorbers, masterbatches and other auxiliary materials can also be added to EVA geomembrane to improve its waterproof and anti-seepage properties.
Polyethylene geomembrane: Mainly made of polyethylene (PE) resin, it can be divided into high-density polyethylene (HDPE) geomembrane, low-density polyethylene (LDPE) geomembrane and linear low-density polyethylene (LLDPE) geomembrane according to different densities. Polyethylene geomembrane also has excellent anti-seepage properties and good heat resistance and cold resistance.
2.Performance characteristics
EVA geomembrane:
It has high mechanical indicators, such as strong puncture resistance and large friction coefficient.
Good flexibility, convenient construction and good welding effect.
Excellent aging resistance, can be used for a long time in the exposed state while maintaining performance.
Polyethylene geomembrane:
It has a high anti-seepage coefficient and can effectively prevent water leakage.
It has good heat resistance and cold resistance, and can maintain stable performance in a wide temperature range.
It has excellent chemical stability and can resist corrosion from strong acids, alkalis, and oils.
3.Application areas
EVA geomembrane: It is mainly used in occasions with high requirements for flexibility, weather resistance, and welding performance, such as waterproof projects such as subway projects, tunnels, air-raid shelters, dams, and artificial lakes.
Polyethylene geomembrane: It is widely used in various types of engineering anti-seepage, such as waste landfill anti-seepage, solid waste landfill anti-seepage, tailings treatment plant anti-seepage, sewage treatment plant anti-seepage, power plant conditioning pool anti-seepage, etc. In addition, it is also suitable for municipal engineering, garden engineering, petrochemical engineering, mining engineering, agriculture, and aquaculture.
