Introduction of Geomembrane Welding Machine Geomembrane welding machine is a kind of equipment specially used for connecting and welding geomembrane materials. It usually uses heat fusion or high frequency vibration to heat two pieces of geomembrane through heat fusion or high frequency vibration, so that they can fuse with each other under a certain temperature […]

Geomembrane welding refers to joining two or more geomembrane sheets together by hot-melt or extrusion welding technology to form a seamless connection point to ensure the anti-penetration performance of the geomembrane system. Geomembrane Welding Process Preparation: Clear and level the weld area, make sure it is dry, clean, and dust-free, and inspect the geomembrane for

What are the raw materials of geomembrane？ The main raw material of geomembrane is high-density polyethylene (HDPE). HDPE is a thermoplastic polymer material formed by polymerization of ethylene monomers, with the following characteristics: High density: HDPE has a high molecular weight and density, which gives the geomembrane good mechanical strength and tensile resistance, and can

What are the types of surface types of geomembranes? Geomembrane is an important material used in civil engineering and environmental protection, mainly for anti-seepage, isolation, and reinforcement. The surface of geomembranes usually has the following forms: Smooth surface: The surface of some geomembranes is smooth, which is to reduce the friction force of water flow

Anti-seepage principle of geomembrane Physical isolation: Geomembranes have high sealing and anti-seepage capabilities, which can form a physical barrier that effectively prevents moisture, gas or other liquids from penetrating through soil or rock layers and entering the area below. Geomembranes have low permeability through their own material properties, such as high-density polyethylene (HDPE), which reduces

Geomembrane is a material used for soil seepage prevention, waterproofing and isolation. So what is the process of using geomembrane? Preparation: Before starting to use the geomembrane, it is necessary to ensure that the soil surface in the construction area is level and cleaned. Remove objects such as sharp objects, gravel, and weeds that may

Definition of Geomembrane Geomembrane is an artificial film material used for isolation, anti-seepage, anti-corrosion, reinforcement, etc. between soil and water. It is usually made of high molecular polymers, such as polyethylene (HDPE), polypropylene (PP) and so on. One of the main functions of a geomembrane is to prevent liquids or gases from penetrating into or
