Waterproof Membrane
Dec 11, 2017

polyethylene geomembrane, mainly white opaque translucent to opaque thermoplastic resin material - made of polyethylene resin. Polyethylene is a polymer, is non-toxic, odorless, odorless white particles, the melting point of about 110 ℃ -130 ℃.


impermeable membrane has good heat resistance and cold resistance. Good chemical stability, high rigidity and toughness, good mechanical strength, good resistance to environmental stress cracking and tearing strength, mechanical properties and barrier properties correspondingly increased with the increase of density, heat resistance and tensile strength Higher intensity; acid, alkali, organic solvents and other corrosion.


Impermeable membrane is pe film as a substrate, and geotextile composite impermeable material, its impermeability mainly depends on the pe membrane. PE membrane applied to the East impermeable membrane, mainly polyvinyl chloride and polyethylene, EVA (ethylene / vinyl acetate copolymer), which is a polymer chemical flexible material, the proportion of smaller, more extensible, to adapt to the deformation capacity High, corrosion-resistant, low temperature, frost resistance is good. The main mechanism is that the impermeable plastic film divides the earth dam leakage passage, and withstands the water pressure with its larger tensile strength and elongation and adapts to the dam deformation.
