Geomembrane is a geotechnical anti-seepage material composed of plastic film as the anti-seepage substrate and non-woven fabric.
The geomembrane has dual functions of waterproofing and preventing plant roots from penetrating, and can withstand the puncture of plant roots and has waterproof functions.
Creates a waterproof layer that is highly resistant to pressurized water and puncture-resistant.
The specific function of geomembrane and the length of service life should consider the following three aspects:What are the performance characteristics of HDPE geomembrane?
The quality of the geomembrane is whether the material used to produce the geomembrane has sun-resistant ingredients.
The inherent quality of the geomembrane, from the perspective of new materials and recycled materials, the service life of the new material geomembrane is long.
The use environment of geomembrane, in the anti-seepage project, the use of geomembrane is laid in the sun and in the soil, and the service life of the geomembrane will be extended when it is protected from light.
The raw materials of geomembrane include polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP), polyamide (PA), modified polyethylene (CPE), etc.
Among them, polyethylene and polyvinyl chloride are the main raw materials for production, and a certain anti-aging agent will be added during the processing, so that the durability is long.
In addition, the geomembrane is also made of raw materials, refined from crude oil, with high toughness, high strength, and more expensive
Is geomembrane a mulch?
Mulch film, agricultural film, and greenhouse film are all one kind in general. Both mulch film and greenhouse film belong to mulch film, and the early agricultural film is the same process as geomembrane, which only reduces the thickness and increases the light transmittance.
In the later period, after technological development and planting needs, nano-technology such as multi-layer, defogging, and surface anhydrous were derived, forming a series of new production processes and methods.
Geomembrane is a kind of polymer material, also called mulch film or anti-seepage film, which has good impermeability, corrosion resistance and aging resistance, and can effectively prevent moisture and chemicals in the soil from penetrating into the underlying soil or groundwater
Widely used in agriculture, gardens, construction and other fields
As is known to all, geomembranes can be applied in many industries, such as waste landfills anti-seepage, water management, reservoirs anti-seepage projects, etc.
In recent years, with the development of geomembranes material science and the improvement of geomembranes performance, the application of geomembranes has become more extensive and the scale of their use has become larger and larger.
Geomembranes are gradually popular with engineering personnel due to their advantages of easier construction, shorter construction period, and lower cost.
