Sodium bentonite as the main raw material for the latest multi-purpose waterproof blanket, using acupuncture, acupuncture blanket waterproof adhesive coating method or processed into law. Sodium bentonite is also known as sodium montmorillonite, it can be expanded more than 24 times with water and after needling process to form very stable colloidal waterproof layer. With low and high viscosity fluid loss characteristics. Is the new, environmentally friendly, eco-sodium bentonite waterproofing membrane composite waterproof blanket (GCL) is a new type of geosynthetics. It is graded by a natural sodium bentonite particles and the corresponding mixing additives for raw materials, technology and equipment acupuncture, the bentonite particles fixed waterproof membrane between blanket and plastic woven geotextile made of. GCL has all the characteristics of both the geotextile material, but also has excellent water (seepage) performance. Waterproof mechanism is: GCL chosen sodium bentonite particles inflatable water more than 24 times, to form a homogeneous high viscosity and low fluid loss colloidal system of high quality multi-purpose waterproof blanket, two layers of geotextile By limiting the role of the bentonite from disorder into order multipurpose waterproof blanket wholesale inflation, persistent swelling bentonite result is to achieve dense layer itself, which has a waterproof waterproof blanket by the production process can be divided into: Acupuncture France sodium bentonite waterproof blanket, coating method acupuncture sodium bentonite waterproof blanket and gluing sodium bentonite waterproof blanket. Coating method acupuncture sodium bentonite waterproof blanket, is on the outer surface of acupuncture sodium bentonite waterproof blanket non-woven geotextile composite layer of high-density polyethylene geomembrane. Gluing sodium bentonite waterproof blanket, the bentonite particles with adhesive bonded to high density polyethylene plate, compress the production of a sodium bentonite sodium bentonite waterproof blanket waterproof blanket as a new environmental and ecological composite impermeable material its unique anti-leakage performance has been in water conservancy, environmental protection, transportation, railway, civil aviation and other widely used in civil engineering. Impermeable landfill cap base processing and artificial lakes, reservoirs, channels, rivers, roof garden seepage, basements, subways, tunnels, underpasses and other underground structures of the class name. Waterproof blanket covered the top of the high-density polyethylene (HDPE) film is lower for non-woven fabric, impermeable layer of sodium bentonite has a textile. The waterproof excellent results sodium bentonite, with a special acupuncture fixed between high strength geotextile nonwoven fabric and then covered with a layer of high-density sticky polyethylene (HDPE) film. This product has a stronger ability than ordinary water seepage of sodium bentonite waterproof blanket. For applications that require high water seepage areas such as: multi-purpose waterproof blanket tunnel, subway, basement, various underground underpass structures and groundwater resources are abundant water features works deal with seepage leakproof. Principle film GCL bentonite mineralogical name for montmorillonite, bentonite according to the chemical composition of natural 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, and adsorption of sodium bentonite water five times its own weight of water, volume expansion to the original 15-17 times above, 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.
