Geomembrane UV resistance test and discussion The national standards GB/T17643-2011 and CJ/T234-2006 both stipulate the anti-ultraviolet performance indicators of geomembranes, but the difference from the American standard GM 13 directive is that after 1600 hours of anti-ultraviolet performance, the geomembrane After the test, it is evaluated by whether the retention rate of OIT before and […]
The influence of geomembrane on soil mechanics Geomembrane is a kind of artificial synthetic material, usually made of polyethylene (HDPE), polypropylene (PP) and other plastic materials. It is used to block, isolate and prevent seepage in the soil. The impact of geomembrane on soil mechanics mainly involves the following aspects: Waterproof isolation: One of the
How to improve the life of geomembrane Improving the life of geomembranes requires a variety of measures, including correct installation, proper maintenance and reasonable use. Here are some ways to increase the life of your geomembrane: Proper Installation: Properly install geomembranes according to the guidelines provided by the manufacturer and the recommendations of professionals. Make
RH test of geomembrane The RH test of geomembrane refers to the measurement and evaluation of the relative humidity (RH, Relative Humidity) of the geomembrane. In civil engineering and underground engineering, controlling the humidity under the geomembrane is crucial, as changes in humidity may affect the stability of the engineering structure and the performance of
Puncture strength test of geomembrane The puncture strength test of a geomembrane is a key test to evaluate its performance against puncture forces. This test helps determine the puncture resistance of the geomembrane when faced with puncture forces, which is critical to the reliability of the geomembrane in projects such as anti-seepage and slope protection.
What is geomembrane used for? Geomembrane is a geotechnical material used for waterproofing, anti-seepage and isolation. Its main function is to prevent moisture, chemicals or other harmful substances from penetrating into the soil or other structures in engineering projects. The following are the main uses of geomembrane: Anti-seepage layer: Geomembranes are widely used in water
What is a geomembrane mat? Grooved geomembrane refers to grooved geocomposite membrane, also known as “geomembrane pad”. It is a multi-layered composite material that usually includes the following main components: Bentonite: The core part of the grooved geomembrane is usually a layer of natural or artificial bentonite, such as montmorillonite or illite. These soils are
Which geomembrane is the cheapest? The price of geomembrane depends on several factors, including material type, thickness, size, brand, market supply and demand, and geographical location. Generally speaking, HDPE (high-density polyethylene) geomembrane is usually the more economical choice, but the specific price will still vary based on the above factors. Here are some factors that
Why do landfills use geomembranes? Anti-seepage effect: Liquid waste will be produced in landfills, such as landfill leachate, rainwater infiltration, etc. If these fluids seep into the ground, they can cause groundwater contamination. As an anti-seepage layer, geomembrane can effectively prevent liquid leakage and prevent harmful substances from entering groundwater. Environmental Protection: Waste in landfills
What is HDPE geomembrane? HDPE geomembrane is a geomembrane made of high-density polyethylene (HDPE) material. HDPE is a thermoplastic with high density, high strength, high chemical resistance and good tensile resistance. The following are some properties and applications of HDPE geomembrane: High Density Polyethylene (HDPE): HDPE is a thermoplastic polyethylene with a relatively high density.
