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. Grenada geotextile material Ltd. Tai'an City environmental engineering experts, seepage famous, the most famous environmental impermeable engineering company, is one of our country's landfills designated special material series, has been receiving a large number of domestic and foreign seepage waterproof anti-corrosion engineering, has accumulated a wealth of engineering experience, enjoy the "best quality, most professional" reputation in the industry. Geomembrane main areas covered are: a environmental engineering seepage: as landfills, sewage treatment plants, power plants regulation pool, industrial, solid waste; b landscape artificial lake: artificial lakes, rivers, reservoirs, golf course the pond bottom, slope, green lawn waterproof moisture and the like; 10, salt: salt crystal pool, brine pool cover, salt film, Salt film.
