Where is the geomembrane manufacturer good?

In Dezhou City, Shandong Province, China geomembrane production base. There are many manufacturers here with good quality. Geomembrane is made of plastic film as impervious substrate and composite non-woven fabric. The anti-seepage performance of new material geomembrane mainly depends on the anti-seepage performance of plastic film. At present, the plastic films used for seepage control at home and abroad mainly include polyvinyl chloride (PVC), polyethylene (PE) and EVA (ethylene/vinyl acetate * * * polymer. In tunnel application, ECB (ethylene vinyl acetate modified asphalt * * * mixed geomembrane) is also designed and used. They are a kind of polymer chemical flexible materials with low specific gravity, strong ductility, strong deformation adaptability, corrosion resistance, low temperature resistance and good frost resistance. Geomembrane is a waterproof barrier material based on polymer, which is mainly divided into low-density polyethylene (LDPE) geomembrane, high-density polyethylene (HDPE) geomembrane and EVA geomembrane. Its width and thickness specifications are complete, and it has excellent environmental stress cracking resistance, excellent chemical corrosion resistance, wide service temperature range and long service life. It is used for landfill, tailings pond, canal seepage prevention, dam seepage prevention, subway engineering and so on. The physical and mechanical mechanism of geomembrane, the main mechanism is to block the leakage channel of earth dam with the impermeability of plastic film, and to bear water pressure and adapt to dam deformation with its great tensile strength and elongation; Non-woven fabric is also a short polymer fiber chemical material, which has high tensile strength and extensibility through needling or thermal bonding. After compounding with plastic film, not only the tensile strength and puncture resistance of plastic film are increased, but also the friction coefficient of contact surface is increased due to the rough surface of non-woven fabric, which is beneficial to the stability of composite geomembrane and protective layer.
