Supply Hubei landscape lake impermeable membrane manufacturer * Quality the root Contact Manager Li 182-6481-7103 look forward to your sincere cooperation development impermeable membrane eighties the rise of a new type of synthetic geotextile waterproofing deadening material, following the soft PVC another new high quality score embedded parts sub leakage prevention materials, chlorine polyethylene (CSPE) and butyl rubber waterproof material. The impermeable membrane applications began in the mid-1980s, the first is impermeable membrane in Canal Seepage, followed by the emergence of HDPE impermeable membrane. Earlier water-impermeable Engineering Henan People's Victory Canal Shaanxi People's cited Wei Drainage, several irrigation areas of the Beijing Dongbeiwang Irrigation District and Shanxi, the use of good effect, and it is later extended to other projects as reservoirs, sluices and reservoirs. Earlier impermeable membrane thickness is thin, not advanced production technology and scientific backwardness limit impermeable membrane thickness, when people use 0.12mm-0.38mm impermeable membrane. The thick impermeable membrane to the early 1990s before applied in our country. 1992 in Liuzhou, Guangxi Tamura dam China are using the highest impermeable membrane, geomembrane rockfill dam, 48m, has been used so far of its impermeable better than expected but also ideal. The cofferdam cutoff wall damming the river of the Yangtze River Three Gorges Project in 1998 also impermeable membrane. In Hanjiang Fu Island Dam dike seepage engineering in 1998 of 1.2 million square meters of impermeable membrane, including HDPE impermeable membrane, LDPE impermeable membrane, geomembrane composite geomembrane. 21st century, with the industrial and scientific development, China's production of impermeable membrane thickness up to 3mm, up to 8m wide, in the world advanced level. Impermeable film production base in China is mainly distributed in the developed cities in East China, such as Beijing, Shanghai, Shandong and other cities. Impermeable membrane has been widely applied to the major anti-seepage project, such as: artificial lakes, golf courses, landfills, tailings disposal stations, tunnels, anti-slip layer of high-speed rail, aquaculture, garden and petrochemical industries. National Institute of geosynthetics continues to develop the use of impermeable membrane. Characteristics of a seepage coefficient - impermeable membrane impermeable effect with ordinary waterproof material unmatched HDPE impermeable membrane has a high-strength tensile mechanical excellent flexibility and deformation capacity makes it ideal for the expansion or contraction of the base surface, can be effectively overcome the uneven base surface subsidence, high water vapor permeability coefficient, chemical stability - impermeable membrane has excellent chemical stability, which is widely used in sewage treatment, chemical reaction pool landfill. High and low temperature, asphalt, oil and tar, acid, alkali, salt and other 80 kinds of strong acid and alkali chemical corrosion resistance, aging resistance - impermeable membrane has excellent anti-aging, anti-UV, anti-catabolic ability to bare use, the material life of 50-70 years, good environmental impermeable material 4, anti-plant root-HDPE impermeable membrane has excellent puncture resistance, resistant to most plant roots, high mechanical strength - anti osmosis membrane with good mechanical strength, tensile strength of 28MPa, elongation at break of 700%, cost-effective high-HDPE impermeable membrane using new technology to improve the anti-seepage effect, but the production process more scientific, speed, Czech Republic, so the cost of the product even lower than traditional waterproof material, HDPE impermeable membrane general engineering cost about 50%, faster construction - high flexibility impermeable membrane, the actual calculations using a variety of specifications to meet the different variety of the laying of the form Seepage Control requirements, using hot-melt welding, high weld strength, construction is convenient, fast and healthy, environmentally friendly non-toxic - impermeable membrane materials used are non-toxic and environmentally friendly materials, seepage principle is a common physical changes do not have any harmful substances impermeable geomembrane of environmental protection, farming, drinking water and pool the best choice for high tensile strength, excellent flexibility: HDPE impermeable membrane has a high strength tensile mechanical, excellent flexibility and strong deformation capacity makes it ideal for the expansion or contraction of the base surface, which can effectively overcome the uneven settlement of the base surface. Seepage performance: HDPE impermeable membrane with high-quality, high-density polyethylene virgin resin made by co-extrusion technology, with a highly efficient molecular density, low liquid permeability, impermeable excellent results. Easy construction, light weight, easy to transport: light weight HDPE impermeable membrane, the finished product into a roll, easy site laying high flexibility to meet the different needs of the construction site.
