Small ribbon you know pe impermeable membrane and composite cloth
The composite geomembrane uses plastic film as the anti-seepage substrate and is compounded with non-woven fabric as the anti-seepage material, its anti-seepage performance mainly depends on the anti-seepage performance of plastic film. At present, the plastic films used for anti-seepage at home and abroad mainly include polyvinyl chloride (pvc)And Polyethylene (PE). Let's get to know pe impermeable membrane and composite cloth.
Small Plait shows you that pe impermeable membrane and composite cloth
pe is a polymer chemical flexible material with small specific gravity, strong extensibility and high adaptability to deformation. Corrosion resistance, low temperature resistance and good frost resistance. The main mechanism is to cut off the leakage passage of the earth dam with the impermeability of plastic film, and to bear the water pressure and adapt to the deformation of the dam body with its larger tensile strength and elongation. Non-woven fabric is also a kind of polymer short fiber chemical material, which has high tensile strength and extensibility through acupuncture or thermal bonding forming. After combining with plastic film, not only the tensile strength and puncture resistance of the plastic film are increased, but also the friction coefficient of the contact surface is increased due to the rough surface of the non-woven fabric, which is beneficial to the stability of the composite geomembrane and the protective layer. At the same time, they have good corrosion resistance to bacteria and chemical effects, and are not afraid of acid, alkali and salt erosion.
