Geomembrane Product Description:
Geomembrane uses plastic film as the impermeable base material and is a geomembrane material compounded with non-woven fabric. The impermeability of the new material geomembrane mainly depends on the impermeability of the plastic film. Plastic films for anti-seepage applications at home and abroad mainly include polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene/vinyl acetate copolymer), and ECB (ethylene vinyl acetate modified asphalt co Concrete membrane), they are a kind of polymer chemically flexible materials, which have a small specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance, and good frost resistance.
Geomembrane is mainly used in landfills, river embankments, lakes, tailings dams, sewage dams and reservoir areas, channels, reservoirs (pits, mines), etc.; subways, basements and tunnels. Tunnel anti-seepage lining. Subgrade and other foundation saline seepage control; horizontal anti-seepage paving in front of the dam, vertical anti-seepage layer of the foundation, construction reclamation, waste yard Seawater and freshwater farms; road highways, railway subgrades; waterproof layers of expansive soils and collapsible loess; roofs are impervious.
Main functions: anti-seepage, isolation.
Products: including LDPE geomembrane, HDPE geomembrane, EVA geomembrane, special geomembrane for breeding.

LDPE geomembrane has the following characteristics:
1. High anti-seepage coefficient-LDPE anti-seepage membrane has an anti-seepage effect unmatched by ordinary waterproof materials. The water vapor permeability coefficient K <= 1.0 * 10-13g. cm / c cm2. s.pa.
2. Chemical stability-LDPE impermeable membrane has excellent chemical stability and is widely used in sewage treatment,chemical reaction tanks, and landfills. High and low temperature resistance, resistance to asphalt, oil and tar, acid, alkali,salt and other more than 80 kinds of strong acid and alkali chemical medium corrosion.
3. Anti-aging performance-LDPE anti-seepage film has excellent anti-aging, anti-ultraviolet and anti-decomposition ability, can be used naked, the material has long service life, and provides a good material guarantee for environmental anti-seepage.
4. Anti-plant root system-LDPE impermeable membrane has excellent puncture resistance and can resist most plant root systems.
5. High mechanical strength-LDPE impermeable membrane has good mechanical strength, excellent elasticity and deformation ability making it very suitable for expansion or contraction of the base surface, which can effectively overcome the uneven settlement of the base surface.
6. Good economic benefits-LDPE anti-seepage membrane adopts new technology to improve the anti-seepage effect. Not only is the production process more scientific and fast, but the product cost is lower than traditional waterproof materials.
7. Fast construction speed-LDPE impermeable membrane has high flexibility. There are various specifications and various laying forms to meet the impervious requirements of different projects. Hot-melt welding is adopted. The weld strength is high and the construction is convenient and fast.
8. Environmental protection--LDPE impermeable membranes are all new raw materials. The principle of impermeability is ordinary physical changes, which will not produce harmful substances. It is a good choice for environmental protection, breeding, and drinking water tanks.
