Mineralogical name of bentonite montmorillonite, bentonite natural chemical composition is divided into sodium and calcium-based two categories. Bentonite has a water swelling properties, while the general calcium bentonite expands, its expansion is only about three times its own volume, and adsorption of sodium bentonite water five times its own weight of water, volume expansion to the original 15-17 times Pengrun more practical waterproof blanket, the sodium bentonite locked in between two layers of geosynthetic materials for protection and strengthening of the role of the GCL has a certain overall shear strength. Construction method of a waterproof blanket, waterproof blanket material larger self, should adopt the shovel machine with waterproof blanket lifting tool handling, laying. 2. Connect waterproof blanket material using an overlapping manner. 3, should be waterproof blanket on slopes greater than 10% of the number of laying minimize overlap along the longitudinal direction of the slope, the slope of the GCL must toe the line more than 1500mm above. D, we will be in strict accordance with the submitted to the supervising engineers design waterproof blanket laying plans to lay Pengrun waterproof blanket, except with the owner or supervision requirements. 4, any equipment used for laying waterproof blanket has been laid not traveling well above geosynthetics. When installing waterproof blanket, outdoor air temperature not lower than 0 ℃ or above 40 ℃. Waterproof blanket waterproof blanket (field of compacted clay liner liner) an impermeable geomembrane liner and polymer materials between. Mainly used in environmental engineering waste landfill, underground reservoirs, underground infrastructure construction projects, solve sealed isolation, anti-leakage problems Edison Pengrun waterproof blanket, the effect is good, strong anti-destructive. By high expansion of sodium bentonite compound filled in a special non-woven geotextiles and professional Pengrun waterproof blanket, with a needle into the legal system bentonite impermeable pad can form many small fiber space, bentonite particles can not like flow in one direction, when the water to form a homogeneous high-density gel waterproof layer in the pad is effective to prevent water leakage. GCL physical parameters: 1, natural sodium bentonite content of 4.5kg / m or more. (ASTMD5261) 2, permeability coefficient: k = α × 10-9cm / sec or less (α = 1-9). 3, thickness ≥5mm. 4, size (length × width): 1.2m × 6m, 2.4m × 30m, 6m × 30m. (Dimensions according to requirements). Edison Edison Pengrun waterproof blanket _ new material (certified) _ Huainan Pengrun waterproof blanket provided by the New Materials Co., Edison. Edison New Materials Co., Ltd.
