As we all know, the main equipment for producing geomembrane in my country is divided into laminating machine and blown film machine. Of course, the equipment is getting more and more advanced, and the produced geomembrane has been greatly improved in terms of vision and physical chemistry. So, how are the blue and green impermeable geomembrane processed? In theory, in actual design, users usually design with black and green on the other side or blue on the other side. In addition, when the two sides are colored, they are used for special projects. It is called black green and black blue. If you simply produce reverse osmosis membranes with the same color on both sides, you can make a laminating machine. When producing black-green or black-blue impermeable membranes, blow molding equipment is required for processing. Special masterbatch materials and ultraviolet strong carbon black are added in the production process, which has excellent durability.

The composite geomembrane is composed of one layer of geotextile and one layer of hdpe geomembrane or two layers of hdpe geomembrane. The geomembrane is a layer of hdpe film. What is the difference between the two? Geotextiles only need thermal fusion materials, and composite geotextiles need stitched geotextiles.

The anti-seepage geomembrane is polyvinyl chloride and polyethylene, a polymer chemically flexible material, which has the characteristics of small proportion, high elongation, strong deformation habit, corrosion resistance, low temperature resistance and good cold resistance.

The anti-seepage geomembrane is a new type of synthetic geotextile waterproof barrier material produced in the 1980s.

Many users generally ask some manufacturers early when purchasing composite geomembrane.
