GCL chosen sodium bentonite particles of water swellable more than 24 times, to form a homogeneous high viscosity and low fluid loss colloidal system, in two layers of geotextile limit the role of the bentonite changed from disorder orderly expansion, sustained swelling result is to achieve dense bentonite layer itself, which has a waterproof effect. GCL is a cross between an impermeable liner GCL (site of compacted clay liner liner) and polymer materials ---- geomembrane between. Because sodium bentonite-based natural inorganic material, even after a very long time or the surrounding environment changes, aging or corrosion will not occur, so Bentonite is a natural inorganic material, harmless, non-toxic, no particular impact on the environment, with good environmental performance. GCL by the production process can be divided into: acupuncture sodium bentonite waterproof blanket, coating method acupuncture sodium bentonite waterproof blanket and gluing sodium bentonite waterproof blanket. Editing a suitable environment, municipal engineering, subway, underground engineering and building roof reservoir seepage. 2, environmental sanitation, solid waste landfills, sewage treatment plants waterproof blanket factory, industrial waste. 3, water, rivers, lakes and reservoirs dam seepage, sealing, reinforcement. 4, garden artificial lake seepage and other golf course pond. 5, petrochemical, mining, agriculture and other areas of engineering seepage, corrosion, leakage and reinforcement. Notes Editor 1, bentonite composite waterproof pad (GCL) of storage should be waterproof, moisture, strong sunlight prolonged sun exposure. Floors should be taken during storage overhead paving method, transported to the site of bentonite composite waterproof pad (GCL) should be used the same day. 2, during the next process or an adjacent construction, has completed the process to deal with bentonite composite waterproof pad (GCL) properly protected, without any man-made damage. 3, should avoid wearing spiked shoes, high heels stepping on bentonite composite waterproof pad (GCL) on; GCL detailed construction drawings (2) vehicles and other machinery can not be compacted bentonite composite waterproof pad (GCL). 4, professional GCL, GCL has paved the completion of the construction should be completed by GM / GCL composite liner of the day construction or laying HDPE film 300mm thick clay layer of protection, can not be completed HDPE film or protective layer of clay construction quality GCL, GCL response be covered in case of rain snow before leaving the GCL hydration and GCL strong sunlight for prolonged sun exposure. 5, a single layer of GCL impermeable liner, waterproof blanket waterproof construction project, the construction is completed and after acceptance, shall be promptly greater than the proportion of soil, sand or stone tablets 2.0 backfilling. To prevent damage to the GCL backfill, and backfill should not contain more than 10mm diameter larger than gravel backfill thickness of not less than 30cm. Backfill should be graded backfill compaction, the degree of compaction of not less than 85%. Shandong Edison Group (FIG), the best waterproof blanket, waterproof blanket Baishan new material provided by the Edison Company. Edison New Materials Co., Ltd.
