Geomembrane requirements for temperature and wind is what geomembrane to temperature and wind requirements: geomembrane construction requirements for temperature and wind are very strict, so the temperature and wind at the time of the geomembrane construction, the impact is still great , then what are the requirements for it. Look together. A temperature 5-40 ℃ is appropriate, taking into account the thermal expansion and contraction of HDPE geomembrane, based on experience, cold weather, laying geomembrane should bear some hot days when relaxation; but note that in the summer should be avoided Two high-temperature, wind and rain at noon: the wind over four or rain should repose construction; wind speed hours, to use sand bags to suppress geomembrane, in turn goes forward, in order to facilitate the construction site construction quality meets the design requirements: base surface should dry, compacted, smooth, no cracks, no significant jagged, uneven. Its flatness should be gradual change in the range of permitted average slope, slope thick consistency. TAG: Specific requirements for welding of HDPE geomembrane HDPE geomembrane impermeable membrane longitudinal seam: uphill section on the downhill section of the next practical Geomembrane, and there is enough overlap length ≥15cm, slope HDPE must be in the membrane impermeable membrane, impermeable membrane reservoir bottom acceptance GCL area after laying laying artificial certain direction quality Geomembrane, a "push shop" when the slope impermeable membrane laying, sand Bags will be positive and timely, ride together film direction substantially parallel to the exhibition should be the maximum slope line. Impermeable membrane to suppress, prevent wind and pulling. HDPE impermeable membrane weld preparation: experimental welding requirements: 1, experimental welding is produced under the same surface of the weld and environmental conditions. 2, welding equipment and welding personnel only after the successful completion of the pilot Geomembrane welding, to the next step in the production of welding. 3, seams without oil, dust, HDPE geomembrane lap segment surface sediment and other debris should be sandwiched necessary before welding clean when there is debris. 4, experimental welding on HDPE impermeable membrane samples to test and adjust the welding equipment. 5, experimental welding frequency control: according to the ambient temperature changes, at least twice each day, once before the formal job, once in Geomembrane manufacturers, Edison new materials (certified), anti-Wanzhou seepage geomembrane provided by Edison New Materials Co.. Edison New Materials Co., Ltd. (www.fangshenmo.com) Shandong Texas, 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. New material in Edison led the staff warmly welcome all inquiries negotiations to create new materials Edison a better future.
