Ⅰ.Product Introduction
The production equipment of composite geomembrane adopts the latest technology of membrane pulling, and can produce composite Geomembrane with various specifications such as one fabric one membrane, two fabrics one membrane and multi-fabrics multi-membranes (The base fabric is made of needle-punched geotextiles, and can also be made of filament woven fabric or plastic woven fabric.). The production process not only maintains the good mechanical properties of the geotextiles, but also makes the composite product uniform in membrane thickness and high in peeling strength, avoiding the formation of pores and blisters on the membrane, and greatly improving the impermeability of the membrane.
Ⅱ.Product Function and Effect
The composite geomembrane uses geotextiles (woven fabric or plastic woven fabric) as the base fabric, so it not only has the functions of geotextiles’ isolation, drainage, reinforcement, protection, etc., but also has a closed (seepage prevention) function. The composite geomembrane can be widely used in many areas such as irrigation works, dams, road construction, airports, drainage, houses, environmental protection, etc., especially, it mainly plays the role of seepage prevention, protection and reinforcement in construction.
