Geomembrane is reinforced modified polyethylene or PVC, calender film forming and polyester geotextile heat is made with a tensile strength, bursting resistance, high tear strength, elongation properties, deformation modulus macro Cheung Geomembrane, anti-aging, anti-seepage performance, use a long period and so on. After it is combined with plastic film, not only increases the tensile strength and puncture resistance of the plastic film, and because of non-woven surface roughness and increase the contact surface of the friction coefficient, is conducive to protective layer of geomembrane and geotextile stable Since the film with these characteristics, in Canal Seepage Treatment promote the adoption of Geomembrane wholesale and achieved good economic and social benefits. The specific requirements of HDPE geomembrane HDPE impermeable membrane welding longitudinal seams: the uphill sections of the downhill section in the next, and there is enough overlap length ≥15cm, the slope must be impervious geotextile HDPE impermeable membrane at a film film library at the end GCL impermeable membrane laying area after acceptance of laying artificial certain direction, the "push shop" impermeable membrane impermeable geomembrane manufacturers of slope paved with sand bags in a timely manner will be positive and take Sarkozy should show the film direction substantially parallel to the maximum slope line. Squeeze the impermeable membrane to prevent the wind pulling. HDPE impermeable membrane welding preparation: experimental welding requirements: 1, the test of the weld is a production of welding the same surface and environmental conditions. 2, welding equipment and welding personnel only after the successful completion of the pilot welding, to the next step of production of welding. 3, seams without oil, dust, surface HDPE geomembrane lap segment should not contain sediment and other debris, it is necessary to clean up before welding when 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, every day, at least twice, once before the formal job, once in the quality Geomembrane, Geomembrane West, by the Edison Group New Materials Co., Edison provided. Quality Geomembrane, Geomembrane West, Edison Group Edison New Materials Co., Ltd. (www.fangshenmo.com) this year introduced a new upgrade, the above picture is for reference only, please call this page or image on the telephone, to obtain the latest information, contact: song manager.
