Geomembrane, widely used in canal seepage control project. In recent years, geosynthetics in civil engineering latest waterproof composite film, especially a large number of applications and their effectiveness in flood rescue project, causing the majority of engineering and technical staff are highly valued. Geosynthetics for the application of technology, the country from seepage, filtration, drainage, reinforcement, protection and other aspects of proposed normative technical requirements, greatly accelerated the pace of promotion and application of new materials. The material is widely used in irrigation canal seepage control project, combined with the construction practice, the application of technology of composite geomembrane. As a geotextile material impermeable engineering application, geomembrane has good qualities people very reassuring. For geomembrane is concerned, we must be able to withstand erosion, rain sun exposure, in addition to be able to withstand a lot of external factors such as the complexity of the geological movement, strong pressure and stretching. Geomembrane for better corrosion resistance can be good for bacteria and chemical and acid, alkali, salt erosion prevention, long life, gives us a good sense of security. Metal refining process will produce a considerable amount of tailings, tailings will pollute the surrounding environment and the ecosystem in a certain extent. Therefore, the establishment of impermeable geomembrane composite tailings dam system has a very important meaning. Soma Canada can produce geomembrane smooth and rough surfaces, which can get very rough surface geomembrane good application on steep slopes with a tailings dam. Geomembrane matte surface matte particles, increasing the friction coefficient, but also increases the stability of the slope. Canadian production as Soma practical waterproof matte geomembrane composite film can even reach 0.75mm, is three times the international indicators, greatly enhances the stability of the landfill. Impermeable geomembrane base mainly in plastic film as raw material, in addition to geotextile impermeable material, impermeable material look good and good performance is mainly to see the bad plastic film. In China, applied to impervious plastic film, is an extension of the characteristics of this material is strong, corrosion-resistant, the proportion of small, low temperature, high deformation capacity to adapt, there is a strong freezing capacity. Civil engineering composite materials now being constantly updated, functional materials is also rising. Now out of a new type of composite geomembrane to synthetic material as the main material of warp geomembrane, warp geomembrane and general type of geomembrane is not the same. Warp geomembrane There are many features with low elongation, high tensile strength, performance characteristics, but also has a strong waterproof, so warp geomembrane is a strong protection, isolation materials, in the international community to get a very high level. In China waterproof composite film, there are many manufacturers producing geomembrane, products either in the top or in the quality of the above specifications are quite good, but also a wide variety of species. In the choice of the time there are two options, according to the actual situation of the factory, you can also make a separate production according to the manufacturer's requirements. Impervious body has a very unique structure consists of four layers are: base, geomembrane, stone revetment, a protective layer, each layer is designed to be laying the base surface design, geomembrane design, protective layer design, armor design, each layer has a great attention to design, and strive to achieve the most perfect works. Select the appropriate geomembrane, in the process of laying Special attention should be waterproof composite film, laying geomembrane engineering tightness should be moderate, not too tight nor too loose. During the construction of the stones must be avoided, it should at the same time each project, while laying the membrane, while covering the protective layer. Waterproof composite film composite membrane waterproofing manufacturers _ _ Edison Danzhou new material (see) provided by New Materials Co., Edison. Edison New Materials Co., Ltd. (www.fangshenmo.com) strong, credible, in Dezhou site construction materials industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Edison new materials into the brilliant and you work for a better future!
