　　Composite geomembrane is a geotextile anti-seepage material composed of plastic film as the anti-seepage substrate and non-woven fabric. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. At present, plastic films for anti-seepage applications both domestically and internationally mainly include polyvinyl chloride and poly. They are a type of polymer chemical flexible material with a small specific gravity, strong extensibility, and high adaptability to deformation. Composite geomembrane is a very good material that can be used frequently in daily life, and through certain technological improvements, it can also be utilized in many engineering projects. They all understand the waterproof ability of composite geomembrane and what it can bring them. Composite geomembrane is an impermeable material made of geotextile and geomembrane composite materials. The advantages of this production are as follows: 1. Compared with the nitrogen filling and roughening method, there will be no formation of bubbles or holes on the surface or inside of the geomembrane, which will affect the various indicators of the geomembrane. 2. Compared with the rolling and stretching method, the equipment investment is relatively small, the processing cycle is short, and the rough surface of the geomembrane produced by the rolling method is uniform, flat, and the surface force is relatively small. If different specifications of rough surfaces are needed, the rolling roller needs to be constantly replaced. 3. Due to the fact that the wire spraying roughening method involves secondary roughening after the production of geomembranes, there is a relaxed requirement for raw materials during the production of geomembranes. And for manufacturers with both blown film equipment and rolling equipment, there is no need for equipment modification to produce rough geomembranes. 4. The spray wire roughening method is suitable for producing geomembranes with different thicknesses of rough surfaces.
