High strength, good self-tightness, high elongation, aging resistance, non-toxicity, no pollution to the environment, etc.,

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, corn......

The 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 strong resistance to pressurized wate......

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 impermeab......

1. Lightweight: Polypropylene resin is used as the main raw material for production, with a specific gravity of only 0.9, which is only three-fifths of cotton. It is fluffy and feels good. 2. Soft: It is composed of fine fibers (2-3D) and is formed by light-point hot-melt bonding. The finished prod......
