HDPE Geomembrane

Performance characteristics of HDPE anti-seepage geomembrane:

1. High anti-seepage coefficient - HDPE anti-seepage membrane has an anti-seepage effect that cannot be compared with ordinary waterproof materials. HDPE anti-seepage membrane has high tensile mechanical properties, and its excellent elasticity and deformation ability make it very suitable for expansion or shrinkage bases. The surface can effectively overcome the uneven settlement of the base surface, and the water vapor permeability coefficient K<=1.0*10-13g.cm/c cm2.s.pa.

2. Chemical stability—HDPE anti-seepage membrane has excellent chemical stability and is widely used in sewage treatment, chemical reaction tanks, and landfills. High and low temperature resistance, resistance to asphalt, oil and tar, acid, alkali, salt and more than 80 kinds of strong acid and alkali chemical media corrosion

3. Aging resistance—HDPE anti-seepage film has excellent anti-aging, anti-ultraviolet and anti-decomposition capabilities, and can be used exposed. The service life of the material is 50-70 years, providing a good material guarantee for environmental anti-seepage

4. Resistance to plant roots—HDPE anti-seepage membrane has excellent puncture resistance and can resist most plant roots

5. High mechanical strength - HDPE anti-seepage membrane has good mechanical strength, tensile strength at break 28MP, elongation at break 700%

6. Low cost and high benefit - HDPE anti-seepage membrane adopts new technology to improve the anti-seepage effect, but the production process is more scientific and fast, so the product cost is lower than traditional waterproof materials. According to actual calculations, the general project using HDPE anti-seepage membrane To save about 50% of the cost

7. Fast construction speed - HDPE anti-seepage membrane has high flexibility, and there are various specifications and laying forms to meet the anti-seepage requirements of different projects. It adopts hot-melt welding, and the weld seam has high strength, and the construction is convenient, fast and healthy

8. Environmentally friendly and non-toxic—the HDPE anti-seepage membrane is made of non-toxic and environmentally friendly materials. The principle of anti-seepage is ordinary physical changes and does not produce any harmful substances. It is a good choice for environmental protection, breeding, and drinking pools

9. Good welding effect - HDPE anti-seepage membrane is welded by special welding machine, the welding effect is very good, the strength of the weld is greater than that of the base material, and it is convenient for construction

Application fields of HDPE anti-seepage geomembrane:

 1. Environmental protection and sanitation (such as domestic waste landfills, sewage treatment plants, power plant regulating pools, industrial and hospital solid waste, etc.)

 2. Water conservancy (such as anti-seepage, plugging, reinforcement of rivers, lakes, reservoirs and dams, anti-seepage of canals, vertical core walls, slope protection, etc.)

6. Mining industry (washing tank, heap leaching tank, ash dump, dissolution tank, sedimentation tank, storage yard, anti-seepage of bottom lining of tailings, etc.)

7. Traffic facilities (road foundation reinforcement, culvert seepage prevention)

8. Agriculture (reservoirs, drinking water pools, storage ponds, anti-seepage of irrigation systems)

9. Aquaculture industry (intensive and factory farming ponds, fish ponds, lining of shrimp ponds, sea cucumber circle slope protection, etc.)

10. Salt industry (salt field crystallization pond, brine pond thatch cover, salt film, salt pond plastic thatch film)
