Geomembrane is a kind of waterproof barrier material with high quality polyethylene primary resin as the basic raw material.
Mainly products are HDPE Geomembrane, PVC Geomembrane, LDPE Geomembrane, EVA Geomembrane etc.
1. Complete width and thickness specifications.
2. Has excellent resistance to environmental stress cracking performance and excellent resistance to chemical corrosion.
3. Excellent chemical resistance.
4. Has a larger operating temperature range and a longer service life.
5. Used in landfills, tailings storage sites, channel seepage prevention, dyke seepage prevention and subway engineering, etc.
HDPE geomembrane (also known as impermeable membrane), with a thickness of 0.2-3m and a thickness of more than 0.8mm, is also known as waterproof board. It is a kind of waterproof and barrier material based on high-quality polyethylene primary resin. The main components are 97.5% HDPE and 2.5% carbon black
PVC geomembrane is PVC waterproof,it is a kind of high quality polymer waterproof board,Through the addition of plasticizer,anti-ultraviolet agent,anti-aging agent stabilizer and other processing AIDS in PVC resin,the polymer waterproof rolling material is produced by extrusion method.Thickness:0.8mm-2.0mm.Roil length:20m or customizable.Color:black or according to your request.
EVA geomembrane is one of the geomembrane series products. EVA is ethylene-vinyl acetate copolymer. It has good flexibility, flexibility, elasticity, weather resistance, environmental stress crack resistance and adhesion performance. Higher than ordinary polyethylene, because it has strong flexibility at the same time, it is very convenient in construction and the welding effect is very good.
The rough surface geomembrane is used as an impermeable base material. It is a geotechnical impermeable material processed by a special process formula through roll extrusion or blown film roughening treatment. The performance of the new material geomembrane is mainly isolation and impermeability. . At present, the geomembranes used in anti-seepage applications at home and abroad mainly include polyvinyl chloride (PVC), polyethylene (PE), EVA (ethylene/vinyl acetate copolymer), and ECB (ethylene vinyl acetate modified) is also designed for tunnel applications. Asphalt blend geomembrane), they are a kind of polymer chemical flexible material, with small specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance and good frost resistance. Single-rough surface and double-rough surface geomembrane can increase the coefficient of friction with the contact surface and enhance the anti-slip function of the geomembrane. It is especially suitable for slopes, steep slopes and vertical seepage prevention, and improves engineering stability.
As a new type of material, the anti-seepage geomembrane for aquaculture has excellent anti-seepage, anti-corrosion properties, good chemical stability, and can be processed according to actual engineering needs. It has been widely used in dikes and dams in water conservancy projects. , Reservoir anti-seepage, and also used as anti-seepage, anti-corrosion, anti-leakage and moisture-proof materials in channels, reservoirs, sewage pools, swimming pools, building construction, underground buildings, garbage dumps, environmental engineering, etc. Developed countries have widely used this technology since the 1930s, and my country has gradually promoted the use of HDPE impermeable membranes in various projects since the 1980s.
