Anti-seepage membrane

Geomembrane paving is completed, should minimize walking on the membrane surface, moving tools, etc., where the geomembrane can cause harm to the object, should not be placed on the membrane or carry walking on the membrane, so as not to cause accidental damage to the membrane. When laying geomembrane, we should strive to weld less, under the premise of ensuring the quality of welding, and try to save raw materials. The lap width of the joints between the membrane and the membrane is generally not less than 10cm, and the weld seams are usually arranged parallel to the larger slope, i.e. along the direction of the slope.

PRODUCT DETAILS

Product Description

The standard name of the anti-seepage membrane is polyethylene geomembrane, which is mainly made of milky white translucent to opaque thermoplastic resin material - polyethylene resin. Polyethylene is a high molecular polymer, which is non-toxic, tasteless and odorless white particles with a melting point of about 110℃-130℃ and a relative density of 0.918-0.965; the anti-seepage membrane has good heat resistance and cold resistance. Good chemical stability, high rigidity and toughness, good mechanical strength, environmental stress cracking resistance and tear resistance. As the density increases, the mechanical properties and barrier properties will increase accordingly, heat resistance, and tensile strength. The strength is also higher; it can resist corrosion such as acids, alkalis, and organic solvents.
