1. The friction coefficient of rough geomembrane is high - the small particles on the surface of high-strength, high elongation, and environmentally resistant rough geomembrane increase the friction coefficient and stability of the slope, thereby maximizing the usable volume that smooth HDPE geomembrane can bear.
2. The anti-seepage coefficient of rough surface geomembrane - High strength, high elongation, and environmental resistance. Rough surface geomembrane has a permeability coefficient K<1.010-13g/cm/cm2. s.pa, which cannot be compared with ordinary waterproof materials.
3. Roughness Geomembrane Chemical Stability - High strength, high elongation, and environmental resistance. Roughness Geomembrane has different chemical stability and is widely used in sewage treatment, chemical reaction tanks, landfill sites, high temperature resistance, asphalt, oil tar resistance, acid resistance, alkali resistance, salt resistance, and more than 80 strong acid and alkali chemical media corrosion.
4. Aging resistance of rough geomembrane -- high strength, high elongation and environmental resistance The rough geomembrane has good aging resistance, UV resistance, decomposition resistance, and can be used naked. The service life of the material can reach 50-70 years, providing good environmental impermeability.
5. Rough surface geotextile film is resistant to plant roots - it has high strength, high elongation, and environmental resistance. Rough surface geotextile film has heterogeneous resistance to penetration and can resist most plant roots.
1. Oil depot anti-seepage
It is inevitable for oil materials to leak large or small during transportation, processing, storage, and other processes. If the protective measures are not tight, it will directly lead to oil materials leaking into the sea through soil pores, polluting water bodies and causing marine pollution. If large-scale leakage occurs, it will affect the ecological balance and cause marine ecological disasters. To prevent oil leakage and protect the environment, it is necessary to take measures to address the leakage from the root. The second anti-seepage layer or firewall of the oil depot has been established through rough geomembrane, which can effectively block the pollution caused by oil tank leakage or rupture to the soil.
2. Artificial lake anti-seepage
In order to maintain the normal water level of artificial lakes and other water systems, reduce the cost of artificial lakes, and do a good job in anti-seepage work for artificial lakes has become our main choice, which is also a better solution that we have to choose. HDPE film has more obvious anti-seepage effect and flexibility compared to traditional cement concrete, stone stacking, coating anti-seepage, etc. It is an environmentally friendly product with good anti-seepage performance, convenient construction, and easy maintenance.
An untreated garbage dump has become a long-term source of pollution, seriously polluting groundwater. The harmful gases generated by garbage are directly discharged, polluting the air and seriously affecting the surrounding environment. In response to this situation, we should adopt a comprehensive landfill anti-seepage system to coat the garbage with a raincoat. Let these issues not be a problem.
