I think there are still many friends who don’t understand our composite geomembrane! What is our composite geomembrane? What is the unit price of composite geomembrane? Now, let us learn together.

Geomembrane is a high molecular weight polymer plastic film.

What is composite geomembrane? What is the unit price of composite geomembrane?





Geomembrane uses plastic film as a waterproof substrate and non-woven fabric. Its impermeability mainly depends on the impermeability of the plastic film. At present, the plastic films used for leak prevention at home and abroad are mainly polyvinyl chloride (PVC) and polyethylene (polyethylene), which are flexible polymer chemical materials with low specific gravity, strong ductility and strong adaptability. Deformed. Corrosion resistance, low temperature resistance and good frost resistance. The main mechanism is to isolate the leakage channel from the earth dam through the impermeability of the plastic film, and to withstand the water pressure with higher tensile strength and elongation to adapt to the deformation of the earth dam. Non-woven fabric is also a short polymer chemical material. Through needle punching or thermal bonding, it has high tensile strength and ductility. When combined with plastic film, it not only increases the tensile strength and puncture resistance of the plastic film, but also increases the friction coefficient of the contact surface due to the rough surface of the non-woven fabric, which is conducive to the stability of the composite geomembrane and the protective layer . At the same time, they have good resistance to bacteria and chemical corrosion, and are not afraid of acids, alkalis and salts.

Geomembrane is a high molecular weight polymer plastic film made of polyethylene plastic particle resin. According to its quality, geomembrane can be divided into non-standard, national standard, new material and urban construction. The specifications range from 0.2mm to 3.0mm.

Taking the national standard 0.2mm geomembrane as an example, its unit price is about 1.7 yuan per square meter.
