1. Large friction coefficient-the small particles on the surface of the rough HDPE geomembrane increase the friction coefficient and increase the stability of the slope, thereby maximizing the usable volume that the smooth HDPE geomembrane can carry.
2. Impermeability coefficient-rough surface HDPE geomembrane has a permeability coefficient K<1.0*10-13g.cm/ccm2.s.pa which cannot be compared with ordinary waterproof materials.
3. Chemical stability--The rough surface HDPE geomembrane has good chemical stability and is widely used in sewage treatment, chemical reaction tanks, landfills, high temperature resistance, asphalt, oil and tar, acid, alkali, salt, etc. More than 80 kinds of strong acids and alkalis are corroded by chemical media.
4. Anti-aging performance--The rough surface HDPE geomembrane has excellent anti-violet, anti-decomposition ability, and can be used in the open. The service life of the material is 50-70 years, which provides a good guarantee for environmental protection against permeation.
5. Resistance to plant roots--the rough surface HDPE geomembrane is resistant to penetration and can resist most plant roots.
6. High mechanical strength-the rough surface HDPE geomembrane has good mechanical strength and excellent elasticity and deformability, making it very suitable for expansion or contraction of the base surface. It can effectively overcome the uneven settlement of the base surface. The tensile strength at break is 28MP. The elongation at break is 700%.
7. The construction is several times fast-the rough surface HDPE geomembrane has good flexibility. There are many specifications and multiple laying forms to meet the anti-seepage requirements of different projects. It adopts hot-melt welding, high welding strength, convenient and fast construction.
8. Environmental protection and non-toxicity-The materials used in the rough surface HDPE geomembrane are all non-toxic and environmentally friendly materials. The anti-seepage distance is ordinary physical changes and does not produce any harmful substances. It is the choice for environmental protection, breeding, and drinking water ponds.
