The anti-seepage geomembrane is polyvinyl chloride and polyethylene, which are soft raw materials of polymer chemistry. It has the characteristics of small proportion, high elongation, strong deformation, corrosion resistance, low temperature resistance and frost resistance.
The mechanism of the anti-seepage geomembrane is that the leakage channel of the earth-rock dam is disconnected by the impermeability of the plastic film. The plastic film is subjected to water pressure. With the improvement of the tensile strength and elongation, it can adapt to the deformation of the dam body;
Impermeable geomembrane is also the chemical data information of polymer short fibers. According to needle punching or heat sealing, it can obtain higher tensile strength and elongation, and not only improve the composite plastic composition. Because the surface of the non-woven fabric is not smooth, the tensile strength and puncture resistance of the data information film increase the friction coefficient of the contact surface, which is beneficial to the reliability of the composite geomembrane and protective layer. They have excellent resistance to bacterial corrosion and chemical action, not afraid of acid, alkali and salt corrosion.
1. Corrosion resistance, long-term corrosion resistance in different pH, soil and water.
2. The water conductivity in the gap between the flat wires is excellent, so it has excellent water permeability.
3. It has very good resistance to microorganisms and moths.
4. The project construction is convenient. Because the raw materials are light and soft, transportation, paving and engineering construction are very convenient.
