Introduction of Geomembrane
Simply put, geomembrane is impermeable, geotextile is permeable, and geotextile is made of non-woven fabric, which is mainly used to strengthen the foundation. Geomembrane is made of high-density polyethylene, which is mainly used for seepage prevention.
Geotextiles have woven geotextiles and nonwoven geotextiles, which have excellent filtering, drainage, isolation, reinforcement, anti-seepage, and protection functions, lightweight, high tensile strength, good permeability, high-temperature resistance, freeze resistance, resistance Aging, and corrosion resistance.
The wholesale HDPE geomembrane uses a plastic film as an anti-seepage base material. It is a polymer chemical flexible material with a small specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low-temperature resistance, and good frost resistance.
Geomembrane is mainly used in projects with high anti-seepage requirements such as anti-seepage, isolation, reinforcement, anti-cracking, reinforcement, and horizontal drainage.
Geotextiles are used for reverse filtration, and geomembrane is used to prevent seepage. “Both geotextiles and geomembrane can act independently or can be combined into a whole to play their respective strengths.
The HDPE geomembrane factory price uses a plastic film as an anti-seepage base material, and a geotechnical anti-seepage material compounded with non-woven fabric. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. At present, plastic films for anti-seepage applications at home and abroad mainly include polyvinyl chloride (PVC) and polyethylene (PE), which are a kind of polymer chemical flexible materials, which have a small specific gravity, strong extensibility, and high adaptability to deformation.
Corrosion resistance, low-temperature resistance, and good frost resistance. The main mechanism is to block the leakage channel of the earth dam with the impermeability of the plastic film, with its large tensile strength and elongation, to withstand the water pressure and adapt to the deformation of the dam body; and the non-woven fabric is also a polymer short fiber chemistry The material has high tensile strength and elongation through needle punching or hot bonding. After it is combined with plastic film, it not only increases the tensile strength and puncture resistance of the plastic film but also because of the rough surface of the non-woven fabric. The friction coefficient of the contact surface is increased, which is beneficial to the stability of the composite geomembrane and the protective layer.
At the same time, they have good erosion resistance to bacteria and chemical action and are not afraid of acid, alkali and salt erosion.
