The anti-seepage membrane has excellent anti-aging, anti-ultraviolet and anti-decomposition ability, and can be used. The service life of the material is 50-70 years, which provides a good material guarantee for environmental anti-seepage.
What are the common construction requirements for impermeable membranes?
When the temperature is below 5 ° C, it should not be used according to specifications
textured geomembrane factory price. If construction is required, the welder should preheat before welding. In addition to protective measures, welding is not allowed in rainy weather or when there is moisture, dew, or heavy sand at the joints. When welding, it should be powered by a generator with good regulation performance. When using local power under special circumstances, a regulator must be used. During the welding process, the slider of the spray gun head should be checked frequently during the welding process. When the wear is serious, the slider should be replaced in time to avoid damage to the membrane surface.
The impermeable membrane has an impermeable effect unmatched by ordinary waterproof materials. The impermeable membrane has high tensile and mechanical strength, and its excellent elasticity and deformability make it very suitable for expanding or contracting the base surface, and can effectively overcome the base surface. Uneven settlement and high water vapor permeability coefficient. What is the quality inspection and control method in the construction of anti-seepage
LDPE geomembrane factory price?
Earthwork: The quality of the base surface should meet the design requirements. The dry moisture content should be 15%. The base should be dense and even. The basic dry density of the soil should not be less than 1.4t / m2. Flat, no cracks, no obvious spikes, no mud, no depressions, no roots, rubble, stones, steel bars, 25mm vertical glass fragments. The flatness should change slightly within the allowable range, the slope is uniform and the slope is consistent.
Material: The geomembrane material used must be qualified, with the corresponding certificate and test report.
Laying aspect: When laying smooth geomembrane, the welding seam should be minimized. On the premise of ensuring quality, save raw materials as much as possible, and easily ensure quality
environmental geomembrane manufacturers. The overlap width of the joint between the film and the film is usually not less than 10 cm, and the welding orientation direction is generally parallel to the maximum slope, that is, arranged along the oblique direction. When laying, artificial folds should be avoided. When the temperature is low, it should be tightened and leveled as much as possible.
The climatic aspect of the construction: the temperature should normally be higher than 5 ° C. The geomembrane should be tight at low temperature, and the geomembrane should be relaxed at high temperature. The wind should be at the fourth level. If there is strong wind, the HDPE geomembrane to be welded should be pressed with sandbags.
Welding: The geomembrane should be powered by the generator and have good adjustment performance during welding. In special cases, when using local power, a voltage regulator must be used. In addition to protective measures
environmental geomembrane factory price, welding is not allowed in rainy weather or when there is moisture, dew, or heavy sand at the joints. When the temperature is below 5 ° C, it should not be used according to specifications. If construction is required, the welder should preheat before welding.
