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: Who knows the repair method of membrane switch?
- Maintenance method of membrane switch: Just replace the membrane switch panel of the same model and specification. When replacing the membrane switch, you just need to detach its control plate, which can be done as long as you have basic practical ability (but if you don't have the ability, there is no way to do so). If you can't buy the membrane switch panel, you can replace it with a micro-switch. The circuit wiring should be in accordance with the old membrane switch panel, and the panel needs drilling, installing the micro-switch, fixing with silica gel and wiring.
- Q: How do geomembranes prevent groundwater contamination?
- Geomembranes prevent groundwater contamination by acting as a barrier between potentially harmful substances and the groundwater. They are impermeable liners that are installed beneath the surface, preventing the migration of pollutants from entering the groundwater system. This barrier effectively isolates contaminants, such as chemicals, waste materials, or liquids, preventing their infiltration and potential contamination of the groundwater.
- Q: Are geomembranes resistant to punctures from human activities?
- Yes, geomembranes are generally designed to be resistant to punctures from human activities. They are made from durable materials such as high-density polyethylene (HDPE), which have excellent puncture resistance. However, the level of resistance may vary depending on the specific type and thickness of the geomembrane used.
- Q: What are the advantages of using geomembranes in mining operations?
- There are several advantages of using geomembranes in mining operations. Firstly, geomembranes act as a barrier to prevent the leakage of potentially harmful chemicals or pollutants into the surrounding environment, protecting both the ecosystem and human health. Secondly, these membranes provide stability to the mining site by preventing soil erosion and maintaining slope integrity. Additionally, geomembranes can be used to separate different layers of materials, facilitating efficient waste management and improving overall operational efficiency. Lastly, geomembranes are highly durable and resistant to corrosion, ensuring long-term effectiveness and cost-effectiveness in mining operations.
- Q: What is the typical thickness of a geomembrane?
- The typical thickness of a geomembrane can vary depending on the specific application and requirements, but it is generally in the range of 0.5 to 2 millimeters.
- Q: Geomembrane is used for anti-seepage system which layer structure? What are the materials for the anti-seepage system?
- What kind of project do you elaborate; I am a manufacturer
- Q: How to use 3M light box film?
- There are many kinds of light box film, colored semi transparent film, uniform light film, light blocking film, double color film, etc. Color semi transparent film is the most commonly used. There are many colors for you to choose. Customize colors according to customers' demand. Make back lighting display board by cooperating with soft lamp-box fabric. The construction method of film sticking is divided into: Dry paste method and wet paste method. It depends on different products.
- Q: How do geomembranes contribute to stormwater filtration?
- Geomembranes contribute to stormwater filtration by acting as a barrier that prevents pollutants and contaminants from seeping into the ground or water bodies. They are impermeable and provide a protective layer, ensuring that stormwater runoff is properly managed and filtered before it reaches natural water sources. This helps to reduce the level of pollutants, sediments, and harmful substances in stormwater, ultimately protecting the environment and improving water quality.
- Q: Are geomembranes resistant to fire?
- Yes, geomembranes are generally resistant to fire. They are typically made from materials like high-density polyethylene (HDPE) or polyvinyl chloride (PVC) that have low flammability and are self-extinguishing. However, the level of fire resistance may vary depending on the specific type and thickness of the geomembrane.
- Q: How to stick the film on lampblack machine?
- You can just use the preservative film. 1. Pulling the preservative film from its packaging and putting the film on the smoke exhaust hood. Cutting off the film with a blade when the film is stuck to the edge. 2. Pressing and strenghtening the film on the smoke exhaust hood. 3. Sticking the preservative film all over the oil box of the smoke exhaust ventilator. When there is lot of oil, the old film can be repalced by the new one to avoid cleaning the ventilator. Here are some tips. 1. When the preservative film gets dirty, you can just replace it with a new piece. 2. Usually, the film can be changed once a month. 3. In the kitchen, when sticking the film, it is best to pull the film in its package without pulling the membrane core out so that the film can be stuck flat and easily cut off.
