The Hot Melt Coating Machine to produce HDPE sheet Geomembrane: It is the new and the best technology used for water proof and seepage proof lining. Polymer self-adhesive film waterproofing membrane is made by a special high-density polyethylene film as the main waterproof layer coated with Hot Melt Adhesive and embedded with sand. 70mm wide self-adhesive leap edge is provided on the long side edges. The Hot Melt self-adhesive layer and the anti-environmental changes protective layer has a self-healing function. After solidification with the liquid concrete, non gap combination between waterproof layer and concrete structure, avoid the risk of the seepage between the layers. It can effectively improve the reliability of waterproof system. The products have good puncture resistance, and high tensile strength, also have excellent dimensional stability and anti-UV and high tear resistance in two-way. Advantage: 1. Corrosion resistance: the coil has good acid and alkali resistance, chemical corrosion resistance and excellent aging resistance in various environments. 2. Safety installation non-polluting environment, simple and clean installation. Application： It is used for roof, basement, swimming pool and subway tunnel. It is also suitable for the construction of wood and metal structure roofing waterproof works. It is especially suitable for military installations requiring cold construction and for oil storage facilities, chemical plants, textile mills, grain depot, etc.
