Impermeable membran—防渗膜

Impermeable membrane

The standard name for anti-seepage membrane is polyethylene geomembrane, which is mainly made of thermoplastic resin material - polyethylene resin, which is milky white and semi transparent to opaque (black). Polyethylene is a high molecular polymer, a non-toxic, odorless, and odorless white particle with a melting point of approximately 110 ℃ -130 ℃ and a relative density of 0.918-0.965; The anti-seepage film has good heat and cold resistance. Good chemical stability, high rigidity and toughness, good mechanical strength, good resistance to environmental stress cracking and tear strength. As the density increases, the mechanical and barrier properties will correspondingly improve, and the heat resistance and tensile strength will also be higher; Can withstand corrosion from acids, alkalis, organic solvents, etc.

As the name suggests, the anti-seepage film focuses on the word "anti-seepage" and is mainly used in industries such as municipal environmental protection, water conservancy anti-seepage, landscaping, transportation infrastructure, and aquaculture. And the prefabrication of special components for temporary container structures such as anti-seepage, anti-corrosion, leak prevention, reinforcement, and collection of leachate.
