Chemical Resistant and Temperature Adaptable HDPE Textured Geomembrane for Landfill Sites
Product Introduction
Spray Coarse Geosynthetics Membrane is a special geosynthetic material. It is produced on the basis of traditional polyethylene impervious membrane production technology by updating production equipment to form a granular rough surface on the produced geomembrane. This design not only improves the frictional performance of the geomembrane surface but also has stronger tensile strength compared to the same specification smooth film.
Product Properties
1. Impermeability: Inherited the excellent impermeability characteristics of HDPE geomemofilm, effectively preventing the penetration of water and pollutants.
2 Chemical corrosion resistance: It has good chemical corrosion resistance and can resist the erosion of various chemical substances.
3. Resistance to environmental stress cracking: It can also maintain stability under harsh environmental conditions and is not easy to crack.
4. Temperature adaptability: can be used in a wide temperature range, with good heat resistance and cold resistance.
5. Surface textures: Specially designed columnar or point-like textures that provide additional friction and adhesion.
6. High coefficient of friction: The rough surface of the column points increases the coefficient of friction with soil or other covering materials, helping to prevent the geomemofilm from sliding on the slope.
Product Application
The application field of the sprayed rough geomembrane is very extensive. It can be used for landfill sites, tailings storage sites, channel seepage prevention, dike seepage prevention, and subway projects, etc. In these projects, the sprayed rough geomembrane can not only play a seepage-proof role but also enhance the membrane's anti-bearing deformation force, suitable for slope membrane surface projects that require covering soil and have a large friction coefficient.
