Water-swellable bentonite particles, to form a uniform colloidal system, in two layers of geotextile limiting effect, so that the bentonite swelling from disorder to become ordered, continuous swelling bentonite layer itself so that the result is to achieve dense, so as to have waterproof. Seepage principle mineralogical name of bentonite montmorillonite, bentonite according to the chemical composition of natural sodium and calcium are divided into two categories based. Bentonite has a water swelling characteristics of professional sealed waterproof blanket, when calcium bentonite expands, its expansion is only about three times the volume of the best self-sealing waterproof blanket, and five times its own weight of water adsorbed sodium bentonite water expansion to 15-17 times more than the original, the sodium bentonite locked in between two layers of geosynthetic practical sealed waterproof blanket, from the protection and strengthening of the role of the GCL has a certain overall shear strength. Waterproof blanket price cheap, the quality of its products is a new geosynthetics, it is from the outside layer of low permeability clay or other mineral materials or geomembrane fabric casing workers sealed waterproof blanket, through acupuncture or suture environmental and ecological method of composite made of impermeable material, according to project needs, you can stick on a waterproof blanket cover HDPE film to accommodate the special needs of the environment, to achieve a more ideal seepage effect. This product is good overall performance, high tensile and shear strength, impervious seal bentonite sandwiched An inorganic material, highly expanded water, produce hydration, the formation of impermeable impermeable body gel, but this bentonite have the ability to store moisture absorption, moisture content of up to 10 times its own weight, with a permanent waterproof performance. The company will always uphold the "good governance, excellence and dedication," the quality, continuously forge ahead, focused on the Chinese civil engineering materials business, willing to work with you in good faith to create a bright future, and make greater efforts to the national infrastructure and contributions to practical sealed waterproof blanket, Edison new materials (certified), Datong sealed waterproof blanket provided by the New Materials Co., Edison. Edison New Materials Co., Ltd. (www.fangshenmo.com) quality services and products, and are subject to approval and confidence in the new and old customers and the industry.
