Description of geomembrane quality indicators Geomembrane CBR Bursting Strength CBR bursting strength refers to the maximum load per unit area that the soil sample receives when it reaches the specified damage standard under the action of heavy load. CBR (California Bearing Ratio) test is one of the test methods used to evaluate soil bearing capacity. […]
Manufacturing and testing of HDPE geomembrane products should be the latest version and revised in accordance with the following standards or equivalent and compared to a higher standard, if not in China, please examine according to the origin of the inspection standard. Tensile test of geomembrane Sample Preparation: Cut representative specimens, usually rectangular in shape,

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

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

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
5 Application Areas of Geomembranes Geosynthetic materials, also known as geosynthetics, are thin film materials made from polymer materials through special processing, which have excellent physical and chemical properties. Its application fields are very extensive, including the following aspects: Waterproof field: Geomembranes are mainly used in various anti-seepage projects, such as landfill sites, road tunnels,
What is a geomembrane？ Geomembrane is a new type of environmentally friendly anti-seepage material. The main component is high molecular polyethylene. This component is closely related to our life. The plastic products in daily life are high molecular polyethylene. Of course,geomembrane also has other materials. , what I share with you today is the 8
HDPE geomembrane welding requirements The HDPE geomembrane process is the most critical process in the entire anti-seepage system. The success or failure of the entire project depends on the construction quality of the artificial geomembrane. Therefore, in the construction, every process and every link must be strictly organized and carefully constructed. HDPE geomembrane welding generally
