The anti-seepage geomembrane is polyvinyl chloride and polyethylene, a polymer chemically flexible material, which has the characteristics of small proportion, high elongation, strong deformation habit, corrosion resistance, low temperature resistance and good cold resistance.
The mechanism of the anti-seepage geomembrane is that the seepage channel of the earth-rock dam is blocked by the impermeability of the plastic film. The plastic film is subjected to water pressure, and as the tensile strength and elongation increase, it can adapt to the deformation of the dam.
Impermeable geomembrane is also a chemical data of polymer short fibers. It uses needle punching or thermal bonding to achieve higher tensile strength and elongation. After compounding, it not only improves the composition of the plastic. This is because the surface of the nonwoven fabric is not smooth, and the tensile strength and wear resistance of the data film improve the friction coefficient of the contact surface, which is beneficial to the stability of the composite geomembrane and the protective layer. At the same time, it has excellent resistance to bacterial attack and chemical effects, and does not worry about acid, alkali, salt corrosion.
Polymer synthetic fibers can maintain full compressive strength and elongation under dry and wet conditions.
1. Anti-corrosion, under different pH values, soil and water can resist corrosion for a long time.
2. The conductivity between the flat wires is very good, so it has very good breathability.
3. Excellent resistance to microorganisms and moths
4. The construction is convenient, because the material is light and soft, so it is very convenient for transportation, laying, and construction.
Function: High breaking strength, anti-creep and anti-corrosion. It can be used as water conservancy projects, dams, highway construction, airports, engineering buildings, environmental protection and other engineering projects, and can play the role of filtration, drainage, isolation, safety protection, structural reinforcement.
