　　2、 The performance characteristics of Beijing 1.5HDPE geomembrane are as follows:

　　HDPE geomembrane is a flexible waterproof material with a high anti-seepage coefficient (1 × 10-17 cm/s)

　　2. HDPE anti-seepage film has good heat and cold resistance, and its operating environment temperature is high at 110 ℃; Low temperature -70 ℃

　　HDPE geomembrane has excellent chemical stability and can resist corrosion from strong acids, alkalis, and oils, making it a good anti-corrosion material

　　4. HDPE anti-seepage film has high tensile strength, which enables it to meet the needs of high standard engineering projects.

　　5. HDP light facial mask has strong weather resistance and anti-aging performance, and can be used without exposure for a long time to maintain the original performance.

　　6. HDPE rough facial mask adopts three separate feeders, each layer of different ingredients can have unique performance, which improves the engineering performance of HDPE geomembrane.

　　7. The overall performance of HDPE geomembrane. HDPE geomembrane has strong tensile strength and elongation at break, which enables it to be used in various harsh geological and climatic conditions. Adapt to uneven geological settlement with strong strain force.

　　8. HDPE anti-seepage film is made of qualified native plastic and carbon black particles without any preservatives. HDPE has been used in China to replace PVC as a raw material for food packaging bags and cling films. Our company's HDPE geomembrane has good engineering performance and a wide range of applications.

　　3、 Construction method of 1.5mmHg HDPE geomembrane in Beijing:

　　Before laying HDPE geomembrane, the corresponding qualified acceptance certificate of civil engineering should be obtained.

　　Before cutting HDPE film, its relevant dimensions should be accurately measured and then cut according to the actual size. Generally, it is not advisable to cut according to the dimensions shown in the diagram. Each piece should be numbered and recorded in detail on a dedicated form.

　　When laying HDPE geomembrane, efforts should be made to minimize welding seams and save raw materials as much as possible while ensuring quality. It is also easy to ensure quality.

　　4. The overlap width between membranes is generally not less than 10cm, and the welding seam is usually arranged parallel to the steep slope, that is, along the slope direction.

　　5. Usually, in corners and deformed areas, the joint length should be minimized as much as possible. Unless otherwise specified, welding seams should be avoided as much as possible within a range of 1.5 meters from the top slope or stress concentration area on slopes with a gradient greater than 1:6.

　　During the laying of HDPE geomembrane, artificial wrinkles should be avoided. When the temperature is low, it should be tightened and leveled as much as possible.

　　After the installation of HDPE geomembrane, walking and moving tools on the membrane surface should be minimized as much as possible. Any objects that can cause harm to the HDPE membrane should not be placed on or carried on the membrane to avoid accidental damage to the membrane.
