HDPE Geomembrane is used more and more frequently in everyday life, e.g. cellars, tunnels, rooftops and other special environmental anti-sicker fields are all in use. Here we are going to introduce more about HDPE Geomembrane. Let’s see together.
How to weld HDPE Geomembrane?
Why do we choose HDPE Geomembrane?
What should be considered when using HDPE Geomembranes?
1. The welding process with the hot-wire welding machine is divided into: adjust pressure, adjust temperature, adjust speed, check welding cover, insert film into the machine, start engine and weld pressure.
2. The joints of the HDPE Geomembrane should be free of oil and dust, and the overlapping section of the HDPE Geomembrane should not have deposits such as mud and sand. If dirt is present, it must be cleaned before welding.
3. At the beginning of each welding day, an on-site test piece of 0,9 mm x 0,3 mm with an overlapping width of at least ten cm welded and a on-site shearing and shearing test shall be carried out. Once the sample is qualified, it may be adapted at that time. Good speed, pressure and temperature are just welds. The date, time and ambient temperature shall be recorded on the sample. When welding HDPE Geomembranes, the hot soak welder shall at all times monitor the operation of the welder and fine tune the speed and temperature according to the actual situation on site.
4. The welding seam of HDPE Geomembrane must be clean, beautiful and free of slip welds and jumps.
1. HDPE Geomembrane has high strength mechanical properties, high tensile strength and excellent elasticity. It is very well suited for extending or tightening the base surface and can effectively avoid unevenness of the base surface and settlements.
2. HDPE Geomembrane is produced by co-extrusion technology with high molecular density, low fluid permeability and good anti-permeability effect.
3. HDPE Geomembrane is light, practical for construction and transport and can meet the requirements of different construction sites.
In addition to the choice of a high-quality HDPE Geomembrane, a rigorous and standardised design is also crucial. All details affect the security and stability of the entire project. Many failed projects are caused by negligence in these difficult to construct or easily overlooked details. Therefore, for a high-quality project, these difficulties and key points need to be handled strictly, and these conditions should not cause any difficulties or problems in the construction process, and should only be handled on a temporary basis, only to complete the construction of the project in order not to cause any major hidden risks for the actual application in the future.
Feicheng Lianyi Plastic Co., Ltd. has been concentrating on the production of HDPE Geomembranes for over ten years. With the variety of high-quality products offered by Dong Guan Do Hearts Technology Co., Ltd, they are confident that we will be your ideal partner.
