GCL (GCL) is a specialized water features for artificial lakes, landfills, underground garage, roof garden, pool, yard chemicals, oil depots and other anti-leakage of geosynthetics, GCL oil high expansion sodium bentonite compound filled in a special non-woven geotextiles and, with a needle into the legal system bentonite impermeable pad can form many small fiber space, is not like bentonite particles flow in one direction, when the water in the mat the formation of a uniform high-density gel waterproof layer, effective to prevent water leakage. GCL GCL is a cross between an impermeable liner GCL (site of compacted clay liner liner) and polymer materials ---- between geomembrane. Mainly used in environmental engineering waste landfill, underground reservoirs, underground infrastructure construction projects of low-composite waterproof blanket, solve sealed isolation, anti-leakage problem, the effect is good, strong anti-destructive. Waterproof blanket principle: bentonite mineralogical name for montmorillonite composite waterproof blanket, according to the chemical composition of natural bentonite sodium and calcium are divided into two categories based. Bentonite has a water swelling properties, while the general calcium bentonite expands, its expansion is only about three times its own volume of sodium bentonite will lock in the middle of two layers of geosynthetic materials for protection and strengthening of the role of the GCL has a certain The overall shear strength. Waterproof blanket (GCL) is a new type of geosynthetics. It is graded by a natural sodium bentonite particles and the corresponding mixing additives made by special technology and equipment of the best composite waterproof blanket, the bentonite particles between two layers of geotextile fixed, made of waterproof blanket, both have all the characteristics of geotextile material, but also has excellent water (seepage) performance. Waterproof mechanism is: water swelling bentonite particles to form a homogeneous colloidal system in limiting the role of the two geotextile composite waterproof blanket manufacturers, bentonite from disorder into order expansion, continued swelling result is to make bentonite achieve dense layer itself, so as to have a waterproof effect. Waterproof blanket Main Specifications: Bentonite expansion coefficient (ml / 2g) ≥24; GCL mass per unit area (g / m2) ≥4500; GCL longitudinal breaking strength (KN / m) ≥10; GCL transverse rupture strength (KN / m) ≥10; GCL longitudinal elongation at break (%) ≤10; GCL transverse elongation at break (%) ≤6; GCL vertical permeability coefficient (cm / s) ≤5 × 10-9; GCL peel strength (N) ≥ 65; GCL anti hydrostatic testing (0.5Mp) 24 hours without leakage.
