What is the service life of geomembrane?
The service life of the geomembrane is related to the method of use. If you pay attention to protection and covering when using the geomembrane, you can effectively extend the service life of the geomembrane. On the contrary, if you do not protect it, the geomembrane will not only be exposed to wind and sun, but also Damaged by many external forces, its service life will naturally be reduced a lot.
The high-quality geomembrane is made of high-density polyethylene, a new material, and has double resistance, namely anti-aging and anti-ultraviolet. If it is protected from light, its service life can reach more than 50 years underground, and it can last more than 5 years when exposed to the outside.
Ordinary geomembranes are produced from recycled or semi-recycled materials, and their service life can generally reach more than 20 years underground.
The difference between epdm geomembrane and hdpe geomembrane
Different materials: EPDM geomembrane is a waterproof barrier material produced from ethylene propylene diene rubber. HDPE geomembrane is a waterproof barrier material produced from high-density polyethylene resin.
Different uses: EPDM anti-seepage geomembrane is suitable for low temperature environment and long-term use occasions. It has excellent weather resistance and aging resistance. HDPE geomembrane is widely used in domestic waste landfill anti-seepage, solid waste landfill anti-seepage, sewage Anti-seepage projects such as treatment plant anti-seepage, artificial lake anti-seepage, tailings treatment, etc.
Is hdpe geomembrane better than epdm geomembrane?
HDPE geomembranes are of better quality than EPDM geomembranes.
HDPE geomembrane is made of high-quality high-density polyethylene (HDPE) raw material, which has high mechanical strength and chemical stability, acid and alkali corrosion resistance, and can be applied to construction projects under various environmental conditions.
EPDM geomembrane is made of raw materials such as ethylene-propylene rubber, styrene-butadiene rubber, and allyl rubber. It has a uniform and dense structure, and has strong anti-aging and chemical corrosion resistance.
What is the price difference between epdm geomembrane and hdpe geomembrane?
EPDM anti-seepage geomembrane is a waterproof barrier material produced from EPDM rubber. It is suitable for low temperature environments and long-term use occasions, and has excellent weather resistance and aging resistance.
HDPE geomembrane is a waterproof barrier material produced from high-density polyethylene resin. It has high mechanical strength and chemical stability, is resistant to acid and alkali corrosion, and can be used in construction projects under a variety of environmental conditions.
The price per square meter of EPDM anti-seepage geomembrane and HDPE geomembrane varies greatly, ranging from tens of yuan to hundreds of yuan.
