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 selection of geomembrane should be comprehensively considered in terms of engineering application, economy, construction technology characteristics and material performance.

After laying and connecting the composite geomembrane, immediately (within 48 hours) backfill the sand gravel or earth material protective layer.

Impermeable geomembrane is made according to national standards and special requirements, and it has advantages different from ordinary impermeable membranes.

In order to effectively improve the construction quality of composite geomembrane, construction quality control must be done. Generally speaking, quality control must be ensured from two aspects. One is to ensure the quality of raw materials, and the other is to ensure the quality of the construction process.

The anti-seepage geomembrane is a kind of milky white translucent to opaque thermoplastic resin.
