Conductive geomembrane and preparation method thereof

Abstract

The invention discloses a conductive geomembrane. The conductive geomembrane is characterized by comprising at least a seepage-proofing layer and a conducting layer. The seepage-proofing layer and the conducting layer are arranged in sequence. The seepage-proofing layer and the conducting layer are combined together. The conducting layer is placed on the bottom layer. The thickness of the conducting layer is 0.01-0.05mm and the resistance value of the conducting layer is 103-105 ohm. The seepage-proofing layer is an insulating layer. The resistance value of the external insulation surface of the insulating layer is more than 108 ohm. The bottom layer of the conductive geomembrane has good electrical conductivity and the upper layer of the conductive geomembrane has good insulating property and the physical performance of the conductive geomembrane is not influenced with the electrical conductivity. Physical and chemical performance of a high density polyethylene geomembrane is kept. Holes and defects of the finished laid geomembrane are convenient and quick to check out with combination of electric leakage detection, and welding and repairing can be timely conducted. Therefore, the quality of a seepage-proofing and water-proofing project is guaranteed.

Description

technical field [0001] The invention relates to a conductive geomembrane and a preparation method of the conductive geomembrane. Background technique [0002] Geomembranes are widely used in anti-seepage and waterproof projects such as landfills, tunnels, canals, reservoirs, sewage treatment pools, and sewage pools. Due to the structural limitations of the above-mentioned geomembrane, there are currently limited detection methods for large-scale detection after the geomembrane is laid. Choose from the detection method. The detection methods cited above have low detection efficiency and low accuracy. For example, the vacuum detection method and the electric spark detection method can only be used to detect welds, but not for large-scale detection of the entire construction site after the geomembrane construction is completed; a large amount of manpower is required in the process of large-scale detection At the same time, there is also the phenomenon that holes and leakage ...

The detection methods listed above have low detection efficiency and low accuracy

For example, the vacuum detection method and the electric spark detection method can only be used to detect welds, but not for large-scale detection of the entire construction site after the geomembrane construction is completed; a large amount of manpower is required in the process of large-scale detection At the same time, there is also the phenomenon that holes and leakage points cannot be detected due to poor grounding, which will have a negative impact on the anti-seepage and waterproof effects of the entire anti-seepage and waterproof project, especially in landfills. Or if there is such a missed inspection phenomenon in the dam, it will bring very serious consequences, such as leakage in the landfill, sewage will pollute the entire underground soil and groundwater, and leakage in the dam may cause dam failure
