Mineralogical name of bentonite montmorillonite, bentonite natural chemical composition is divided into sodium and calcium-based two categories. Bentonite has the best characteristics of water swelling sealed waterproof blanket, general calcium bentonite expands when its expansion is only about three times its own volume, and five times its own weight of water adsorbed sodium bentonite water volume expansion to 15-17 times more than the original, 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 Engineer's waterproof blanket to lay laying design, 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 classification and specification waterproof blanket classification and specifications: New Materials Co., Ltd. Shandong Edison is a professional production of waterproof blanket manufacturers; the Company's production of sodium bentonite waterproofing membrane finished blanket acupuncture mainly by category type (GCL-NP / N) and film type (GCL-OF / N) two kinds. Acupuncture-type (GCL-NP / N): the upper is a non-woven geotextile, the middle layer of natural sodium bentonite, the lower woven geotextile. Mainly apply to ordinary, common base surface water seepage treatment, such as: artificial lake, river water, irrigation canals, ponds, reservoirs, dams and other water conservancy and landscape works, as well as landfill, river training, ecological parks, wetlands environmental engineering film type (GCL-OF / N): After the top of the non-woven geotextile blanket professional waterproof seal, the middle layer of natural sodium bentonite, the lower woven geotextile composite technology finally completed in acupuncture the non-woven geotextile layer HDPE film sticky complex. Mainly applies to rich groundwater sources, more stringent requirements for water seepage of underground construction and municipal transportation projects such as: basement, subways, tunnels, underpasses, airports, railways and municipal roads. Custom-sealed waterproof blanket, Chaohu sealed waterproof blanket, Edison new materials (View) provided by New Materials Co., Edison. Road Zhiyuan, temper forward. Edison New Materials Co., Ltd.
