What is geomembrane?
Geomembrane takes plastic film as the anti-seepage base material, and is compounded with non-woven fabric. The anti-seepage performance of new material geomembrane mainly depends on the anti-seepage performance of plastic film. Plastic films for anti-seepage applications at home and abroad mainly include polyvinyl chloride (PVC), polyethylene (PE), EVA (ethylene/vinyl acetate copolymer). In tunnel applications, ECB (ethylene vinyl acetate modified asphalt blend geomembrane) is designed and used. They are polymer chemical flexible materials with small proportion, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance and good frost resistance.
Characteristics of geomembrane
The composite geomembrane is made of plastic film as the anti-seepage base material and non-woven fabric. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. Plastic films used for seepage prevention at home and abroad mainly include polyvinyl chloride (PVC), polyethylene (PE), ethylene/vinyl acetate copolymer (EVA), which are polymer chemical flexible materials with small proportion, strong extensibility, high deformation adaptability, corrosion resistance, low temperature resistance and good frost resistance.
The service life of composite geomembrane is mainly determined by whether the plastic film has lost its anti-seepage and water separation function. According to the national standard of the Soviet Union, the polyethylene film with a thickness of 0.2m and stabilizer for hydraulic engineering can work for 40 to 50 years in clean water and 30 to 40 years in sewage. Therefore, the service life of composite geomembrane is sufficient to meet the service life of dam anti-seepage requirements.
Scope of application of geomembrane
Zhoutou reservoir dam was originally a core dam, but due to dam collapse, the upper part of the core wall was disjointed. In order to solve the problem of seepage prevention in the upper part, an anti-seepage inclined wall was added. According to the safety demonstration and analysis of Zhoutou reservoir dam, in order to solve the problem of weak seepage surface and dam foundation leakage caused by multiple landslides of the dam, seepage prevention bodies such as bedrock curtain grouting, contact surface grouting, backfill curtain of grab sleeve well and high-pressure jet grouting seepage prevention board wall are adopted in vertical seepage prevention. The upper inclined wall is covered with composite geomembrane for seepage prevention. The lower part is connected with the vertical cut-off wall and the upper part is 358.0m high.

- Q: What are the design considerations for geomembranes?
- Some design considerations for geomembranes include the type of material used, thickness, strength, flexibility, chemical resistance, installation method, and expected lifespan. Other factors to consider are the site conditions, such as slope stability, temperature variations, and exposure to UV radiation. Additionally, the design should accommodate factors like water drainage, gas venting, and potential stressors like punctures or tears. Overall, the design should meet the specific requirements of the project, whether it is for containment, environmental protection, or erosion control.
- Q: How do geomembranes improve water quality in aquaculture?
- Geomembranes can improve water quality in aquaculture by acting as a barrier between the water and the soil. They prevent the seepage of harmful contaminants, such as pollutants or excess nutrients, into the water body. This helps maintain a clean and healthy environment for the aquatic species, reducing the risk of diseases and improving overall water quality. Additionally, geomembranes can also aid in managing water levels and preventing excessive water loss, further contributing to maintaining optimal conditions for aquaculture.
- Q: What are the considerations for geomembrane selection in wastewater storage tanks?
- When selecting a geomembrane for wastewater storage tanks, several considerations need to be taken into account. Firstly, the geomembrane must be chemically resistant to the specific wastewater being stored, as different types of wastewater can contain corrosive or harmful substances. The geomembrane should also have a high tensile strength and puncture resistance to withstand potential stresses and impacts. Additionally, the geomembrane must be impermeable to prevent leakage and seepage of the wastewater. The durability and lifespan of the geomembrane should be considered, as it should be able to withstand long-term exposure to the wastewater and environmental conditions. Lastly, the installation and maintenance requirements of the geomembrane should be evaluated to ensure it can be properly installed and maintained over time.
- Q: What are the advantages of using geomembranes in mining operations?
- The advantages of using geomembranes in mining operations include improved environmental protection by preventing contamination of soil and water, enhanced waste management by containing and controlling hazardous materials, increased safety by reducing the risk of accidents and injuries, and cost savings through efficient storage and transportation of mining by-products. Geomembranes also provide long-term durability and stability, ensuring the integrity of mining structures and minimizing the need for maintenance or repairs.
- Q: Can the mobile phone film be posted again
- Certainly, it is better not use the same film after tearing off, and paste a new one in the shop again, it is inevitable that some fine dust and other impurities are stained on the screen when you paste it again
- Q: Are hdpe anti-seepage film and geomembrane the same?
- It is widely used in many industries such as tunnel, so it is a kind of good environmental protection material. I'm sorry I can't provide. The treatment of petrifaction tailings and water?conservancy hydroelectricity. As for HDPE anti-seepage film itself, it belongs to one kind of geomembranes. The definition of geomembrane is vague because of its chemical performance. HDPE film is the product of petroleum chemical engineering. There are also many geomembranes made from other materials. The anti-seepage engineering involves refuse landfill. As for construction scheme. Currently in the country. There are little categories of geomembrane. It can't react to plenty of chemical constituents. Besides, there are LDPE film and municipal administration principle. Composite geomembrane is mainly used in anti-seepage engineering industry.
- Q: How many kinds of the mobile phone film?
- The most common is the HD film, which is very cheap. The second clearness is the frosted membrane with good feeling, which is not easy to leave fingerprints, and can avoid the situation that there is a lot of greasy dirt on the screen after making a phone call. The disadvantage is the high reflective rate, that is to increase the brightness of the screen, or it cannot see clearly. The diamond film is similar to the nail polish for girls and the feeling of the fluorescence which is not easy to keep the fingerprint and greasy dirt. The disadvantage is same to the frosted membrane, and the fluorescent (or reflective chips) will affect the mobile phone reading sight when the outside is too bright. The frosted membrane and diamond film are flat, not uneven on the surface. The last one is toughened glass film, and also refers to the toughened glass, but the thickness is generally 0.2 to 0.3mm that has the advantages of wear resistance and shock resistance, the disadvantage is easily broken if it is not posted well.
- Q: Where has good geomembrane tensile machine?
- The gate-type structure of main engine of mechanical tensile machine is mainly suitable for rubber, plastics, textiles, geotextiles, waterproofing materials, wire and cable, net twine, metal wire, metal bar, metal plates and other materials tensile test increasing appendage to do bend, tear, peel and other tests detecting instruments
- Q: What should be noticed when geomembrane is welding?
- The success of sewage treatment seepage control project depends on the quality of the geomembrane itself and the quality of its installation and construction.
- Q: How do geomembranes perform in high altitude areas?
- Geomembranes perform well in high altitude areas due to their durability and ability to withstand extreme weather conditions. The high altitude does not significantly affect their performance as they are designed to be resistant to UV radiation, temperature fluctuations, and other environmental factors. Additionally, geomembranes provide effective containment and protection against water, chemicals, and gases, making them suitable for various applications in high altitude areas, such as water storage, mining operations, and landfills.
