Features and uses of impermeable membrane1

Features 1. High anti-seepage coefficient—The anti-seepage membrane has the anti-seepage effect that ordinary waterproof materials can't match. The HDPE anti-seepage membrane has high tensile strength and mechanical properties. Uneven settlement, high water vapor permeability 2, chemical stability—The impermeable membrane has excellent chemical stability and is widely used in sewage treatment, chemical reaction pools, and landfills. High and low temperature resistance, asphalt, oil and tar resistance, acid, alkali, salt and other 80 kinds of strong acid and alkali chemical medium corrosion 3, aging resistance—The anti-seepage film has excellent anti-aging, anti-ultraviolet and anti-decomposition capabilities, and can be used in the open. The service life of the material is 50-70 years, providing a good material guarantee for environmental anti-seepage. 4. Anti-plant root system—HDPE impermeable membrane has excellent puncture resistance and can resist most plant roots5, high mechanical strength—The impermeable membrane has good mechanical strength, tensile strength at break 28MPa, elongation at break 700%6, low cost and high benefit—HDPE anti-seepage membrane adopts new technology to improve the anti-seepage effect, but the production process is more scientific and fast, so the cost of the product is lower than that of traditional waterproof materials. It is actually calculated that the general project using HDPE anti-seepage membrane will save about 50% of the cost7 , the construction speed is fast—The impermeable membrane has high flexibility, and has a variety of specifications and laying forms to meet the anti-seepage requirements of different projects. It adopts hot-melt welding, with high weld strength, convenient construction, fast and healthy. 8. Environmentally friendly and non-toxic—The materials used in the anti-seepage membrane are all non-toxic and environmentally friendly materials. The anti-seepage principle is ordinary physical changes and does not produce any harmful substances. It is the best choice for environmental protection, breeding and drinking water pools. Field anti-seepage and leachate collection and isolation filtration system, sewage treatment tank anti-seepage and soft foundation reinforcement, power plant regulating tank anti-seepage, industrial sewage tank anti-seepage, chemical sewage tank anti-seepage, hospital hazardous solid waste landfill anti-seepage and geotechnical engineering Reinforcement, anti-seepage of artificial wetlands, anti-seepage membranes of sewage purification treatment systems, isolation, reverse filtration, etc.) 2. Water conservancy projects (anti-seepage of artificial lakes, anti-seepage of artificial rivers, geomembrane HDPE geomembrane is used for anti-seepage and anti-seepage of reservoirs and basins) Anti-seepage and plugging of dams, anti-seepage of canals, anti-seepage of diversion culverts, and protection of slopes; geotextiles are used for dam foundation reinforcement, drainage plates for groundwater drainage, drainage and depressurization, etc.) 3. Drainage plate tunnel drainage in municipal construction projects Filtration, drainage and pressure reduction of underground construction projects, waterproof blanket, bentonite waterproof blanket construction basement anti-seepage and artificial river anti-seepage, HDPE anti-seepage membrane planting roof anti-seepage, subway tunnel anti-seepage, roof garden anti-seepage and resistance to plant root puncture damage, Anti-seepage and moisture-proof on the ground of high-end workshops and warehouses, anti-corrosion lining of sewage pipes; external water diversion, pressure reduction and discharge, soft soil foundation reinforcement and drainage, etc. , artificial lake revetment foundation reinforcement, water and gas conduction, artificial wetland anti-seepage, river anti-seepage, slope stabilization, dam strengthening, reservoir anti-seepage, golf course artificial lake anti-seepage, depression greening reconstruction, saline-alkali land and gravel land Reconstruction of green planting layer, reinforcement of mountain slope protection, waterproof and moisture-proof green lawn, etc.) 5. Petrochemical system (seepage prevention of chemical sewage pool, seepage prevention of sewage pool of oil refinery, seepage prevention of oil tank foundation, seepage prevention of oil storage tank of gas station and oil refining Anti-seepage of oil sewage tank in factory, anti-seepage of chemical reaction tank, anti-seepage of sedimentation, anti-seepage and isolation of printing and dyeing sewage tank, anti-seepage and anti-corrosion of electroplating and pickling tank, pipeline lining, etc.) 6. Mining (anti-seepage of washing tank, heap leaching) Anti-seepage of pond, anti-seepage of ash yard, anti-seepage of dissolution tank, anti-seepage of sedimentation tank, anti-seepage of tailings yard, anti-seepage of sewage storage tank, etc.) 7. Foundation reinforcement of road traffic facilities, geogrid highway, geocell Slope protection, groundwater diversion and decompression on the back of drainage board and geotextile lining wall, drainage board for rainwater drainage and drainage on high-speed roads, preventing tires and the ground from generating a water flotation system, anti-seepage and diversion of rainwater ditch on the inner side of mountain roads ; Reinforcement of railway subgrade, reinforcement of anti-seepage and diversion under the ballast, anti-seepage reinforcement of culverts and tunnels, groundwater diversion and moisture-proof protection of circuits) 8. Agriculture (anti-seepage of reservoirs, anti-seepage of drinking water pools, anti-seepage of reservoirs, waste residues) Anti-seepage of treatment field; anti-seepage of water diversion irrigation system) 9. HDPE anti-seepage membrane, HDPE geomembrane, aquaculture industry (intensive breeding pond anti-seepage, factory breeding pond anti-seepage, fish pond anti-seepage, high-level shrimp pond anti-seepage Seepage, slope protection of sea cucumber circle, anti-seepage of aquaculture water diversion channels, captive enclosure of crawling fish, etc.) 10. Salt industry (seepage prevention and isolation of crystallization pond in salt field, anti-seepage in brine pond, and salt film——The salt pond is covered and isolated to speed up the evaporation of the water body, accelerate the crystallization speed of the brine to increase the unit salt production, and the salt pond plastic film)
