In many reservoirs, composite geomembrane uses plastic (thermoplastic polymer), rubber (thermosetting polymer) and composite geotechnical mechanics, but currently my country still widely uses geotechnical mechanics and composite geotechnical mechanics.

The impermeable membrane is non-toxic, odorless, odorless high molecular weight polymer white particles.

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.

The main function of using composite geomembrane in water conservancy projects is to enhance the anti-seepage effect of the entire project. From this perspective, overlapping work is very important for geomembrane.

Composite geomembrane is a composite impermeable material, woven or non-woven fabric is used as reinforcement material, and polyethylene is used as impermeable material. Most of the materials are one cloth and one film, and two cloth and one film. Laying impermeable membrane procedure: When laying the impermeable membrane, please make sure that there is no gap in the corner. If there are gaps, they should be filled in time during construction, and the laying order should be determined according to the specific conditions of the moisture content of the laying site. If there are pores, the air should be vented at the air bubble, and the anti-permeable membrane at the vent should be cleaned for subsidies.

Rpet polyester fabric is your good choice. RPET fabric (Coke bottle environmental protection cloth) is a new type of green and environmentally friendly recycled fabric. Its low-carbon source allows it to create a new concept in the field of recycling. Currently, textiles made of recycled "Coke bottle" recycled fibers are used.
