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 durability problem of anti-seepage geomembrane is a problem that everyone often pays attention to.

Film welding method 1. The welding temperature, speed and pressure are determined after experiments and inspections. 2. The welding should be stopped when the ambient temperature is too high or too low. 3. The welding rod is the same as the membrane material. 4. Every piece of oilfield impermeable membrane is welded on the day of laying. 5. The edge of the upper impermeable membrane at the weld should be polished to an inclination angle of 45° to improve the welding quality of the weld.

Waterproof geotextile is a type of geosynthetic waterproof coating made of polyethylene as a waterproof substrate and geotextile.
