| Title | Geotextile Anti-seepage Effect | ||||
| Description | The anti-seepage principle of PP woven prevent grass growth geotextile mainly resists the water leakage passage of the earth dam by the impermeability of the film, and withstands and adapts to the deformation of the dam body with its large tensile strength and elongation. If the non-woven fabric is combined with the film, not only The tensile strength and puncture resistance of the geotextile can be increased, the friction coefficient of the contact surface is increased, the stability of the protective layer is facilitated, and the defense effect against bacteria is also strong. The PP woven prevent grass growth geotextile enlarger utilization rate can be increased according to the anti-seepage principle. The anti-seepage geotextile (composite geomembrane) uses a plastic film as the anti-seepage substrate, a geomembrane and a non-woven composite geotextile material, and its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. At present, the plastic film for anti-seepage applications at home and abroad mainly includes polyvinyl chloride (PVC) and polyethylene (PE). They are a kind of polymer chemical flexible material with small specific gravity, strong elongation and high adaptability to deformation. Corrosion resistance, low-temperature resistance, good frost resistance, the main mechanism is the watertight passage of the plastic film to block the earth dam leakage passage, withstand the water pressure with its large tensile strength and elongation, and adapt to the dam body to change the bentonite waterproof blanket. The shape and non-woven fabric is also a kind of high-molecular short-fiber chemical material. It has high tensile strength and elongation by needle punching or hot-adhesive forming. When combined with plastic film, it not only increases the plastic film. Tensile strength and puncture resistance, and 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 better corrosion resistance to bacteria and chemicals. Sex, not afraid of acid, alkali, salt erosion. | ||||
