The standard name of anti-seepage membrane is polyethylene geomembrane, which is mainly made of milky white translucent to opaque thermoplastic resin material - polyethylene resin. Polyethylene is a high molecular polymer, which is a non-toxic, tasteless and odorless white particle with a melting point of about 110°C-130°C and a relative density of 0.918-0.965; the anti-seepage film has good heat resistance and cold resistance. Good chemical stability, high rigidity and toughness, good mechanical strength, good resistance to environmental stress cracking and tear resistance, as the density increases, the mechanical properties and barrier properties will increase accordingly, heat resistance, and tensile strength The strength is also higher; it is resistant to corrosion such as acids, alkalis, and organic solvents. Geomembrane is a geotechnical anti-seepage material composed 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. At present, the plastic films used for anti-seepage at home and abroad mainly include polyvinyl chloride (PVC), polyethylene (PE), EVA (ethylene/vinyl acetate copolymer), and ECB (ethylene vinyl acetate copolymer) is also designed to be used in Zhonglian tunnel applications. Modified asphalt blend geomembrane), they are a polymer chemically flexible material with small specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance, and good frost resistance. Application of anti-seepage membrane 1. Environmental protection, sanitation (anti-seepage and leachate collection and isolation filtration system of domestic waste landfill, anti-seepage and soft foundation reinforcement of sewage treatment pool, anti-seepage of power plant regulating pool, anti-seepage of industrial sewage pool, chemical sewage Pond anti-seepage, hospital hazardous solid waste landfill anti-seepage and geotechnical reinforcement, artificial wetland anti-seepage, sewage purification treatment system anti-seepage, isolation, reverse filtration, etc.) 2. Water conservancy projects (artificial lake anti-seepage, artificial river anti-seepage Seepage, geomembrane HDPE geomembrane is used for seepage prevention of reservoir basins and dams, seepage prevention of canals, seepage prevention of water diversion culverts, and slope protection; geotextiles are used for dam foundation reinforcement, and drainage boards for groundwater drainage and guidance 3. Municipal construction engineering drainage plate tunnel drainage reverse filtration, underground construction drainage and pressure reduction, waterproof blanket, bentonite waterproof blanket building basement anti-seepage and artificial river anti-seepage, HDPE anti-seepage film planting roof anti-seepage, subway Anti-seepage of tunnels, anti-seepage of roof gardens and anti-puncture damage of plant roots, anti-seepage and moisture-proof of high-end factory buildings and warehouse floors, anti-corrosion lining of sewage pipes; external water diversion and decompression and external drainage, soft soil foundation reinforcement and drainage, etc. Anti-seepage engineering 4. Garden landscape and greening projects (artificial lake anti-seepage, artificial lake revetment foundation reinforcement, water and air conduction, artificial wetland anti-seepage, river course anti-seepage, slope stability, embankment strengthening, reservoir anti-seepage, golf Anti-seepage of artificial lakes in stadiums, greening transformation of depressions, transformation of green planting layers on saline-alkali land and gravel land, reinforcement of mountain slope protection, waterproof and moisture-proof green lawns, etc.) 5. Petrochemical systems (seepage prevention of chemical sewage pools, anti-seepage of sewage Anti-seepage of tank foundation, anti-seepage of oil storage tanks in gas stations and oil refinery pools, anti-seepage of chemical reaction pools, anti-seepage of sedimentation, anti-seepage and isolation of printing and dyeing sewage pools, anti-seepage and anti-corrosion of electroplating pickling pools, inside pipelines Lining, etc.) 6. Mining (washing tank seepage prevention, heap leaching tank seepage prevention, ash dump seepage prevention, dissolution tank seepage prevention, sedimentation tank seepage prevention, tailings stockyard seepage prevention, sewage storage tank seepage prevention, etc.) 7 , Road traffic facilities Geogrid foundation reinforcement of roads, geocell slope protection, drainage board, geotextile slope lining wall backside groundwater diversion and decompression, drainage board drainage of rainwater on high-speed roads, to prevent tires from forming on the ground Water floating system, anti-seepage and diversion of rainwater ditches inside mountain roads; reinforcement of railway subgrade, reinforcement of anti-seepage and diversion under ballast, anti-seepage reinforcement of culverts and tunnels, groundwater drainage and circuit moisture-proof protection) 8. Agriculture (reservoir anti-seepage Seepage prevention, anti-seepage of drinking water pool, anti-seepage of reservoir, anti-seepage of water diversion irrigation system) 9. HDPE anti-seepage membrane, HDPE geomembrane, aquaculture industry (intensive aquaculture pond anti-seepage, factory aquaculture pond anti-seepage, fish Pond anti-seepage, high-level shrimp pond anti-seepage, sea cucumber ring slope protection, breeding water diversion channel anti-seepage, captive breeding enclosure for crawling fish, etc.) ——Salt pond bedding and isolation to accelerate water evaporation, accelerate brine crystallization speed to increase unit salt production, salt pond plastic tarpaulin)
