The company has rolled and hot composite production line can produce a geomembrane cloth membrane, two cloth one film and more film Dobb variety of geomembrane (using staple acupuncture geotextile fabric, may also be long woven silk, woven plastic). Production process while maintaining good mechanical properties of geotextile fabric, but also the composite product film thickness uniformity, high peel strength. Avoid the air hole is formed on the film, greatly enhance the strength of the membrane permeability. Film surface is embossed to increase the coefficient of friction of a film, not only to improve the stability, the latest hdpe geomembrane engineering, construction and convenient. In many areas, mainly from seepage in engineering, protection, reinforcement and so on. Filtration filtration guidelines for national standard guidelines proposed specification geomembrane, hdpe geomembrane manufacturers, geomembrane used as a filtration geotextile in accordance with our national standard "application of geosynthetics technical specifications" fabric should meet the following guidelines. Soil protection criteria Soil protection filtration material shall conform to the requirements of the following formula geotextile equivalent aperture, where, according to the soil quality of the soil particles smaller than the particle size characteristics of the total mass of soil particle size of soil particles, is determined ; when large fines content soil, and water when taking a reciprocating coefficient, determined according to engineering experience, should adopt a small value. ) Permeability permeability guidelines filtration material shall conform to the requirements of the following formula coefficient, geomembrane determined according to engineering experience, Anshan hdpe geomembrane, not less than formula determined; shall be the vertical permeability coefficient of geotextile permeability coefficient, Edison hdpe geomembrane, soil permeability coefficient) guidelines aiming to halt attempts to prevent the filtration material should be consistent with the requirements described: After-site soil samples geomembrane material made of geotextile and to be selected during the clogging test, the resulting gradient ratio should meet the following requirements when the formula when drainage failure and huge losses, should the proposed use of geotextile and soil material on-site indoor clogging test. For woven geotextile geomembrane, Soil protection criteria may refer to the following provisions: clay, loam, covered with a protective layer material when large-block (sewn clay content greater means woven geotextile equivalent aperture). Under gap is small (eg preform) conditions can, a small gap of sandy soil, geomembrane protective layer covering a large gob (clay content is less than, whichever is greater, or take a small value (eg prefabricated Under pieces) conditions, can be; less than custom hdpe geomembrane Edison wave of new materials (online consultation), Longyan hdpe geomembrane provided by Edison Edison New Materials New Materials Co., Ltd. (www.fangshenmo. .com) is Dezhou, site construction materials leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs in Edison new materials led the staff warmly welcome all walks of life For more information, negotiations to create new materials Edison better future.
