Description and technical indicators of composite geomembrane

RELEASE TIME :

2018-01-29 09:22

We have said a lot about the related knowledge of composite geomembrane before, today I will learn about it with you.

Composite geomembrane is a geosynthetic material composed of two or more materials such as geotextile (or glass fiber mesh) and polymer materials (such as PE film, EVA, etc.). It uses geotextile as the water-conducting layer, polymer material as the anti-seepage layer, and is calendered and hot-melt coated. It has unique anti-seepage, protection and reinforcement, drainage, isolation and other functions. Its high toughness and The excellent chemical corrosion resistance and anti-aging properties exceed the use index of simple application of cloth or film, which is convenient for construction and does not require adhesives. It has wider application fields and is more convenient to use.

  Product Categories:

Composite geomembrane product structure is one cloth and one film, two cloth and one film, two films and one cloth, etc.

Types of base fabrics: needle-punched staple fiber geotextiles, woven geotextiles, non-woven geotextiles, fiberglass mesh, etc.

●Membrane material (polymer synthetic material): high-density polyethylene (HDPE), low-pressure polyethylene (LDPE), chlorinated polyethylene (CPE), EVA (ethylene copolymer), PVC, etc.

Composite Geomembrane

Process characteristics

The composite geomembrane produced by our company is processed by the first casting method and thermal composite method in China.

  Features

1. The width can reach up to six meters. Compared with similar products with narrow width, the seams are reduced, the project cost is reduced, the construction period is shortened, and the hidden dangers caused by improper seam treatment are also reduced.

2. Compared with the traditional cloth and membrane separation, the use of composite geomembrane improves the use effect, saves engineering time, reduces engineering costs, and has obvious comprehensive benefits.

3. Good anti-aging performance. If buried laying is adopted, the service life will be longer.

4. Water pressure resistance, corrosion resistance, high strength, wear resistance, low temperature resistance, non-toxicity, good surface drainage function, and excellent anti-seepage effect.

5. It has unique functions of heat preservation, moisture retention, frost protection and antifreeze.

Uses:

Geotechnical dams, rockfill dams, masonry dams and spreading concrete dams; horizontal anti-seepage bedding in front of dikes and dams, vertical anti-seepage layers for foundations; tailings dams, sewage reservoir dam bodies and reservoir areas; construction cofferdams; Liquid pool (pit, 圹); Waste dump; Subway, basement and tunnel, tunnel anti-seepage lining; Roadbed, highway, railway roadbed; Roadbed and other ground saline prevention; Waterproof layer of expansive soil and collapsible loess; The roof is leakproof.
