Production of impermeable geomembrane

Geomembrane is a geomembrane made of plastic film as an impermeable base material, combined with a non-woven fabric. The impermeability of the new material geomembrane mainly depends on the impermeability of the plastic film. At present, plastic film geomembranes for anti-seepage applications at home and abroad, anti-seepage membranes mainly include polyvinyl chloride (PVC), polyethylene (PE), EVA (ethylene/vinyl acetate copolymer), and ECB ( Ethylene vinyl acetate modified asphalt blend geomembrane), they are a kind of polymer chemical flexible material, small specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance, and good frost resistance. The anti-seepage geomembrane for fish pond tarpaulin is a kind of flexible waterproof barrier material produced by (medium) high-density polyethylene resin as virgin material, without any preservatives. The product itself has a high anti-seepage coefficient (1×10-17 cm/s), and its use environment temperature is high temperature 110℃, low temperature -70℃, anticorrosive materials that can resist strong acid, alkali, oil and other corrosion. It has high tensile strength and can meet the needs of high-standard engineering projects. It has strong anti-aging performance. It can be used naked for a long time while maintaining its original performance. It can be used under various harsh geological and climatic conditions. The products are highly praised by domestic and foreign experts and users in engineering circles.
