How to Distinguish Between Geomembrane and Composite Geomembrane
The difference between composite geomembrane and geomembrane：
Although the composite geomembrane and geomembrane are similar in name, there are significant differences in product morphology, appearance, raw materials and processes. Here are the main differences between them:
Explain in detail：
Product form：
Geomembrane is a single anti-seepage product, while composite geomembrane is a composite anti-seepage product. Composite geomembrane is usually divided into two cloth a membrane and a cloth a membrane, of which two cloth a membrane refers to the upper and lower sides of the geomembrane are composite geotextile, and a cloth a membrane refers to the geomembrane above or below a composite layer of geotextile.
Appearance：
The appearance of the geomembrane is generally black, while the appearance of the composite geomembrane is usually white.
Raw materials and processes：
Geomembrane is mainly produced by polyethylene (PE) resin particles through three-layer co-extrusion process or plate calendering process, while composite geomembrane is produced by thermal composite process of geomembrane and geotextile.
Geomembrane is mainly used in municipal impermeability engineering, culture impermeability engineering, landfill impermeability engineering, tailings treatment field impermeability engineering, reaction pond impermeability engineering, rainwater collection pond impermeability engineering.
In contrast, the composite geomembrane is more used in the seepage prevention of various water conservancy projects, such as river seepage prevention engineering, river control engineering, artificial lake seepage prevention engineering, landscape lake seepage prevention engineering, dam seepage prevention engineering, drainage seepage prevention engineering
Through the above comparison, we can clearly see the differences between composite geomembrane and geomembrane in many aspects, which make them play their respective advantages in different application scenarios.
