Permeable Nonwoven uses plastic film as the anti-seepage base material and is composited with non-woven fabric. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. The plastic films used for anti-seepage applications at home and abroad mainly include polyvinyl chloride (PVC) and polyethylene (PE). They are a kind of polymer chemical flexible material with small specific gravity, strong extensibility, high adaptability to deformation, and corrosion resistance. , Low temperature resistance, good frost resistance. Its main mechanism is to block the leakage channel of the earth dam with the impermeable plastic film, and with its greater tensile strength and elongation, it can withstand the water pressure and adapt to the deformation of the dam; and the non-woven fabric is also a kind of short polymer fiber The material, through needle punching or thermobonding, has high tensile strength and extensibility. After it is combined with the plastic film, it not only increases the tensile strength and puncture resistance of the plastic film, but also due to the rough surface of the non-woven fabric , Increase the friction coefficient of the contact surface, which is conducive to the stability of the composite geomembrane and 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 corrosion.
1.Filtration of soils in drainage applications by retaining soil particles while allowing for the free flow of water.
