Geomembrane is in one or both sides after the film far infrared heating oven, the geotextile and geomembrane by guide rollers pressed together to form a composite geomembrane. With the improvement of the production process of composite geomembrane manufacturers, there is a casting process do geomembrane. In the form of a cloth membrane, two cloth one film, two films a cloth. Geotextile layer of protection as geomembrane geomembrane, impermeable protective layer from damage. To reduce the ultraviolet radiation, increases anti-aging properties, preferably laying buried in France. Hydrostatic geomembrane geomembrane 1. Determination of resistance to hydrostatic pressure on both sides of the principles in the geomembrane head reaches a certain value, geomembrane will break. Progressively increased on both sides of the water sample beat keep and maintain a certain time, when the seepage flow increased rapidly, indicating that the sample is damaged, it won the hydrostatic pressure value of the sample. 2. Keep the pressure geomembrane at least 2h, observed changes in seepage water pipe best composite geomembrane level basically stable (seepage flow is zero) waterproof geomembrane, places 0.1-0.2mpa, for progressively increasing the pressure differential, each level remain 2h, until the emergence of the phenomenon of rapid increase in seepage flow, indicating the specimen rupture has occurred after a pressure that is as hydrostatic pressure (mpa). 3. Just as geomembrane geomembrane determine whether the sample reaches a specified value of hydrostatic pressure can be direct pressure to this pressure and maintain 2h, and then determine that meet the requirements. 4. Determination of geomembrane at least three samples of each sample, the sample with the lowest value as hydrostatic pressure. Shandong Hongxiang Chemical Fiber Group Co., Ltd. was founded in June 1987, October 1997 to form a provincial enterprise groups. The company's total assets of 360 million yuan, covers an area of ??600,000 square meters, existing staff of 976 people, including 248 professional and technical personnel. Major equipment imported from Germany, Italy, Canada, Japan, and has a complete set of sophisticated detection equipment, equipment and professional quality inspection team and the technical team. The company mainly produces geotextile, geomembrane, geotextile, PP woven, waterproof board, PE impermeable membrane, waterproof blanket, composite drainage net, geogrid, water stop, woven geotextile geotextile geotextile material prices and other series. Geomembrane manufacturers, Edison, new materials, Huairou geomembrane provided by New Materials Co., Edison. Edison New Materials Co., Ltd. (www.fangshenmo.com) located in Shandong Lingxian west industrial area. Scraps and development in the wave of market economy, the current Edison new material has a high profile at the site of construction materials, enjoys a good reputation. Edison made the whole network of new materials Commercial Union certification, marking our service and management level has reached a new height.
