The difference between geomembrane and composite geomembrane

RELEASE TIME :

The key to distinguish between composite geomembrane and geomembrane is that composite geomembrane is a new type of composite geomembrane, made of geomembrane and geotextile, and geomembrane is a pure 1-layer plastic film, but both All have anti-leakage performance. In many more rigorous engineering projects, such as garbage disposal sites, composite geomembranes are preferred, and of course the two will also be used.

土工膜与复合土工膜的区别

1. Composite geomembrane is a composite product. Composite geomembranes are usually divided into two cloth and one film and one cloth and one film. As the name implies, two cloth and one film are the upper and lower layers of the geomembrane, and one cloth and one film is the upper or lower part of the geomembrane. The composite geomembrane is protected by a waterproof layer (geomembrane) in the middle, so it can be used in field anti-seepage projects with complex construction environments. Composite geomembranes are widely used in water conservancy dams, traffic tunnels, roads, airports, houses, rivers, river governance, artificial lakes, landscape lakes, canal seepage prevention projects, etc. In the project, it mainly plays the role of isolation, drainage, seepage prevention, protection, reinforcement and reinforcement.

2. Soil film is a plastic product produced by melting and extruding resin particles through high temperature. In addition to the good anti-seepage effect, the soil film also has high tensile strength, high acid and alkali resistance and long service life.

The main application of geomembrane:

Anti-seepage in landfills, sewage ponds, biogas digesters, and waste disposal sites;

River dikes, lake dams, tailings dams, channels, reservoirs (pit, mine);

Subway, basement and tunnel, anti-seepage lining of culverts;

Seawater, freshwater farms;

Foundations of roads, highways and railways; waterproof layers of expansive soil and collapsible loess;

Roof anti-seepage;

The difference between geomembrane and composite geomembrane can be summarized as: different product forms - one is a single anti-seepage product, and the other is a composite anti-seepage product. The difference in product appearance - the appearance of geomembrane is usually divided into black film and white film, while the appearance of composite geomembrane is usually white. Differences in product raw materials and processes - geomembranes are usually made of composite geomembranes produced by plastic resin particles through a three-layer extrusion or flat calendering process. Composite geomembranes are usually produced from geotextiles and geomembranes through a thermal lamination process.

ps: The price difference between geomembrane and anti-seepage membrane.

1. Use the anti-seepage membrane automatic welding machine for hot-melt electric welding. This way of interfacing yields a general range when connected and adapts accordingly.

2. Connect with glue, heat the glue at the contact point. This method allows employees to master, no mechanical equipment and no electrical equipment.

However, it is recommended not to use glued joints, and the soil film with glued joints will have no problem in a short period of time, but due to the basic principle of thermal expansion and contraction in summer and winter, the tensile force of the anti-seepage membrane will be broken. It is used for hot-melt electric welding of soil film automatic welding machine, so that there will be no sequelae.
