Welding geomembrane - geomembrane production base: Grenada geotextile material Ltd. Tai'an City professional geomembrane manufacturer! Deputy: ----- Mazhen Quan Tai'an City Grenada geotextile material Ltd. 1. geomembrane hot wedge welder welding process is divided into: Adjust the pressure set temperature set speed lap weld inspection device into the machine to start the film Madagascar pressure welding. 2. geomembrane seams without oil, dust, surface HDPE geomembrane lap section should not contain sediment and other debris, when the debris must be cleaned before welding, in the event of insufficient length geomembrane , you need to splice long should first transverse weld is good, then welded longitudinal seam, the lateral distance greater than 50cm should weld a T-shaped, can not cross. Adjacent geomembrane weld seam overlap should be wrong, the junction formed between the membrane block, should be T-shaped, to minimize the cross, at the intersection of the longitudinal mode applied to the weld extrusion welder strengthened. When welding the film must not press out the dead fold, laying HDPE geomembrane, according to local temperature change range and HDPE geomembrane performance requirements, set aside the amount of stretching deformation caused by temperature changes. Geotechnical Materials Co., Ltd. Tai'an City Grenada supply geomembrane hdpe geomembrane geomembrane | Geomembrane purposes, Tai'an geomembrane specifications, Huaibei geomembrane, geomembrane performance, geomembrane supply, geomembrane geomembrane uses Categories: Geo film, impermeable membrane, hdpe geomembrane, hdpe impermeable film (high density polyethylene impermeable membrane) ldpe geomembrane (low-density polyethylene geomembrane), impermeable geomembrane, eva geomembrane. Geomembrane product performance: meet the national standard gb / t17643-1998 and the Ministry of Construction "cj / t234-2006" standard. Geomembrane Specifications: Thickness 0.2-2.0mm Width: 6000-4500mm polyethylene geomembrane blow molding and other polymer materials, according to the production of raw materials can be divided into low-density polyethylene (ldpe) geomembrane, high density polyethylene ( hdpe) geomembrane and geomembrane eva, high strength of such products, anti-aging, good welding performance, to facilitate construction. Mainly used for canal seepage control, Dyke dam, lake dam, subway, landfill and other projects.
