Workers geomembrane film impermeable plastic film as a substrate, and non-woven geotextile composite made of impermeable material, its performance depends on impervious impermeable plastic film performance. At present, the application of impermeable plastic film at home and abroad, mainly polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene / vinyl acetate copolymer), also designed to use the tunnel applications ECB (ethylene-vinyl-modified bitumen blend geomembrane), which is a flexible material polymer chemistry, the proportion of small, strong extension ponds geomembrane deformation capacity to adapt to high geomembrane, corrosion resistance, low temperature, frost performance. Mariculture Mariculture film geomembrane advantage, freshwater aquaculture film polyethylene geomembrane compared with traditional anti-leakage material with seepage performance, high strength, elongation, low temperature flexibility, wide format, light weight Low cost, good welding performance, easy construction, good overall performance and other characteristics, by engineering the universal recognition and attention. Different materials used in accordance with polyethylene geomembrane can be divided into low-density polyethylene (PE-LD) geomembrane, ethylene - vinyl acetate (referred EVA) and high-density polyethylene geomembrane (PE-HD, PE-MD) geotextile film. Due to the current raw material for the production of polyethylene geomembrane geomembrane more grades, there are some differences in performance and product quality stability of the resin itself, plus the processing level geomembrane products, storage conditions, the use of premises, construction technology level different aspects, resulting in the use of effects are quite different. Geomembrane for premature aging, stress cracking and other problems of individual projects, resulting in project rework, 2003 we are at home and abroad, and grades of resin used random sampling conducted weathering comparison and selection. The test results will now be sorted out environmental geomembrane reference for practical application. (1) adding a light shielding agent is superior to black geomembrane weathering qualities of light stabilizers added geomembrane, more than a blank resin produced geomembrane. (2) Carbon black master batch (3) weatherability best. (4) base resin with high density polyethylene TR400-1 good choice for environmentally friendly as geomembrane base resin; low-density polyethylene and linear low density polyethylene 9085 LD165 is a good brand ..... ponds geomembrane, Edison new materials (certified), geomembrane provided by New Materials Co., Edison.
