Excellent Tensile Strength and Puncture Resistance of Composite Geomembrane
Excellent Tensile Strength and Puncture Resistance of Composite Geomembrane
The composite geomembrane, also named as impervious geotextile, refers to plastic film as impervious base material. The anti-seepage performance of composite geomembrane mainly depends on the anti-seepage performance of plastic film.
Plastic films used for anti-seepage applications have small specific gravity, strong extensibility, and high adaptability to deformation and corrosion. Resistance, low temperature resistance, good frost resistance.
The main mechanism is that the impermeability of the plastic film prevents the leakage path of the earth dam, its tensile strength and elongation are greater, it can withstand water pressure and adapt to the deformation of the dam body. And the non-woven fabric is also a polymer staple fiber chemical. The material is formed by needle punching or thermal bonding, and has high tensile strength and ductility.
After the anti-seepage geotextile is combined with the plastic film, it can improve the tensile strength and puncture resistance of the plastic film and increase the contact surface. The friction coefficient is beneficial to the stability of the composite geomembrane protective layer.
