Geomembrane manufacturer: Earthwork membrane is a waterproof and barrier material based on high molecular polymer. Mainly divided into: high-density polyethylene (HDPE) and EVA, the standard name is polyethylene geomembrane, mainly made of milky white translucent to opaque thermoplastic resin material polyethylene resin.

Polyethylene is a high molecular polymer, non-toxic, tasteless, tasteless white particles, the melting point is about 110-130, and the relative density is 0.918-0.965. Geomembrane manufacturers said that the earthwork membrane has good heat resistance and cold resistance, chemical stability, rigidity and toughness, and mechanical strength. The internal environment must have good cracking and tearing strength properties. When the density increases, the mechanical properties and interception properties Will increase accordingly, heat resistance and tensile strength will also increase. Can resist acid, alkali, organic solvent and other corrosion. the

The anti-seepage geomembrane is a plastic film that can produce an impermeable effect. Usually, the anti-seepage geomembrane is produced by the production and processing of polyethylene particles.

Geomembrane manufacturers said that anti-seepage geomembranes are mainly suitable for anti-seepage projects, such as anti-seepage in waste landfills, solid waste landfills, tailings treatment plants, sewage treatment plants, power plant conditioning pools, storage tanks, rainwater Seepage prevention projects such as collection pond seepage, oil storage tank foundation, chemical reaction pond seepage, washing pond, heap leaching pond, ash pile, dissolution pond seepage, sedimentation pond, breeding pond, etc.

The geomembrane manufacturer said that the geomembrane uses plastic film as the anti-seepage base material, and the geotechnical anti-seepage material composited with non-imitation cloth is the red anti-seepage material. Generally common are plastic film, fiber film and so on. Agricultural vegetable greenhouses use plastic films, and the anti-seepage performance of new materials mainly depends on the anti-seepage performance of plastic films.

What are the characteristics of geomembrane?

1. Flexible waterproof material with high impermeability coefficient (110-17 cm/s).

2. Good heat resistance and cold resistance, the ambient temperature is 110 and the low temperature is -70.

3. It has good chemical stability and is a good anti-corrosion material to resist the corrosion of strong acid, alkali and oil.

4. Geomembrane manufacturers: It has high tensile strength and can meet the needs of high-standard engineering projects.

5. Strong weather resistance, strong anti-aging performance, and long-term exposure can maintain the original performance.

6. The overall performance is strong, the tensile strength is strong, and the elongation at break is high, so it can be used in various adverse geological and climate conditions. Adapt to uneven geological settlement, strong deformation ability!

7. Geomembrane manufacturers: The use of raw plastic and carbon black particles does not contain preservatives. HDPE has been used in my country to replace PVC with food packaging bags and fresh-keeping film raw materials.

Composite geomembrane refers to the square geomembrane with non-protective geotextile bonded on both sides or one side. Generally applicable to anti-seepage of water conservancy projects. For example: preventing infiltration projects such as rivers, artificial lakes, reservoirs, waterways, wetlands, road and railway subgrades, etc.
