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.
Polyethylene geomembrane has the dual functions of waterproofing and preventing plant roots from penetrating. It can withstand the puncture of plant roots and maintain the waterproof function for a long time. It can form a high-strength waterproof layer, has a strong resistance to pressure water, and is resistant to puncture, cracking, tearing, and fatigue.

In the design of roof waterproof structure, due to the consideration of structural deformation, temperature deformation, shrinkage deformation, vibration and other influencing factors, it is necessary to take the key to deformable parts such as deformation joints, partition joints, roof ridges, cornices, gutters, water downs, entrances and exits. An additional reinforcement layer is provided on the site.
High strength, good self-tightness, high elongation, aging resistance, non-toxicity, no pollution to the environment, etc.,
The polyethylene geomembrane manufacturer uses a brand-new PE material to make a 6-meter plastic film for use in anti-seepage projects. The thickness of the film is 0.75mm to 2.0mm. Geomembrane is a kind of high molecular polymer material.
