Zhengzhou Drainage Board ManufacturerProduct Introduction:156-2152-1000 Manager Shao
Geotechnical membranes are impermeable materials made of plastic films as the impermeable substrate, compounded with non-woven fabrics. The impermeability of new material geotechnical membranes mainly depends on the impermeability of the plastic film.
Currently, the plastic films used for impermeability applications both domestically and internationally mainly include polyvinyl chloride (PVC) and polyethylene (PE),EVA (ethylene/vinyl acetate copolymer), and for tunnel applications, designed for use with ECB (ethylene-modified asphalt blended geotechnical membranes). These are high molecular chemical flexible materials with low specific gravity, high elongation, strong adaptability to deformation, corrosion resistance, low-temperature resistance, and good frost resistance.KKolps33378
Performance Characteristics:Zhengzhou Drainage Board Manufacturer156-2152-1000 Manager Shao
1、HDPE geotechnical membrane is a flexible waterproof material with a very high impermeability coefficient (1×10-17 cm/s);
2、HDPE geotechnical membrane has good heat resistance and cold resistance, with an operating temperature range of high temperature110℃, low temperature-70℃;
3、HDPE geotechnical membrane has excellent chemical stability and can resist strong acids, alkalis, and oil corrosion, making it a good anti-corrosion material;
4、HDPE geotechnical membrane has a high tensile strength, which allows it to meet the requirements of high-standard engineering projects;156-2152-1000 Manager Shao
5、HDPE geotechnical membrane has strong weather resistance and anti-aging performance, maintaining its original properties even after long-term exposure;KKolps33378
6、HDPE geotechnical membrane has overall performance, with strong tensile strength and elongation, allowing it to be used under various harsh geological and climatic conditions. It adapts well to uneven geological settlement!
7、HDPE geotechnical membrane is made from virgin plastic and carbon black particles without any preservatives. HDPE has been used in our country to replace PVC as a material for food packaging bags and cling film.
Mechanism of the Product:156-2152-1000 Manager Shao
The main mechanism is to use the impermeability of the plastic film to block the leakage channels of the earth dam, with its large tensile strength and elongation to withstand water pressure and adapt to dam deformation. The non-woven fabric is also a high molecular short fiber chemical material formed through needle punching or thermal bonding, with high tensile strength and elongation. When combined with the plastic film, it not only increases the tensile strength and puncture resistance of the plastic film but also enhances the friction coefficient of the contact surface due to the rough surface of the non-woven fabric,Zhengzhou Drainage Board Manufacturerwhich is beneficial for the stability of the composite geotechnical membrane and protective layer.
At the same time, they have good resistance to bacterial and chemical corrosion, not afraid of acid, alkali, or salt corrosion, and have a long service life under light-avoiding conditions.156-2152-1000 Manager Shao
In view of the observed results of composite geotechnical membranes in engineering applications, which show a certain degree of anti-aging capability, some documents from certain countries have more lenient regulations on their service life. For example, the former Soviet Union's BCH07-74 "Guidelines for the Use of Polyethylene Waterproof Structures in Earth Rock Dams" states that polyethylene geotechnical membranes can be used for buildings with a service life not exceeding 50 years. The conclusion of a paper published by Linz Company in Austria titled "Long-Term Properties of Polypropylene Composite Geotechnical Membrane Geosynthetic Materials" states: "Field application experience of over 15 years with polypropylene shows that they have high chemical and biological stability; the major damage to the fabric occurs during construction; no significant changes occur after installation;Zhengzhou Drainage Board Manufacturercan be expected to exceed 100 years of stability.
