HDEP HDPE geomembrane geomembrane wholesale factory price wholesale price low Chen Tel: 13639450809 geomembrane (English name: Geomembrane) is an impervious geotextile material. Colors are white and black. Width: 1-8 meters. Thickness: 0.30-2.00 mm. Manufacturing process is divided into: blown film, cast film. Production of the raw materials used are: PVC, polyethylene, ethylene / vinyl acetate copolymer material. Features: proportion of small, strong extension, the ability to adapt to high deformation, corrosion resistance, low temperature, frost performance. The main mechanism is not water cut off earth leakage passage, with its greater tensile strength and elongation to withstand water pressure and adapt to dam deformation. In general construction extends from the bottom of the laying of the high, laying should be left more than 1.50% of the increase, to prepare local subsidence stretch. Slope paving taken from top to bottom order, when the slope laying show films should substantially parallel to the direction of maximum slope line. Geomembrane before cutting, should accurately measure its relative size. Should strive to weld geomembrane laying least seams between the membrane and the membrane lap width is generally not less than 10cm. In construction seepage is generally used in welding fusion welding machine welding construction site. Geomembrane characteristics: geomembrane is a flexible waterproof material, with high seepage coefficient. Has good heat resistance and cold resistance, the use of ambient temperature is high 110 ℃, low temperature -70 ℃. Has good chemical stability, resistant to acid, alkali, oil, corrosion is a good anti-corrosion materials. With high tensile strength, it has a very high tensile strength to meet the high standards of project needs. Has a strong weather resistance, there is a strong anti-aging properties, can be long-term use and maintain the original performance. Strong tensile strength and elongation at break, so HDPE geomembrane can be used in a variety of adverse geological and climatic conditions. Adapt to uneven settlement strain strong. Geomembrane is mainly used for irrigation, transportation, tunnels, airports, metallurgical tailings, waste disposal sites, roofing seepage and other reinforced seepage control.
