HDPE Geomembrane is a method of hot welding to heat the connected surface to melt the surface, and then pressure to make it a body. The sealing track is moved in a certain direction and both sides of the sealing track are reserved. PE film and PET are not sticky. When laying, adjust the sealing direction of each unit to facilitate welding of the two sealing units.
What are the physical properties of HDPE Geomembranes?
How to properly install HDPE Geomembranes under special circumstances?
What should be observed when welding HDPE Geomembranes?
HDPE Geomembrane has excellent chemical resistance (corrosion resistance);
HDPE Geomembrane has excellent resistance to voltage cracks (resistance to voltage cracks in the environment);
HDPE Geomembrane has the lowest permeability;
HDPE Geomembrane has excellent anti-UV performance;
HDPE Geomembrane has a stable resistance to spraying at low temperature.
1. The intersection point of the bends is the corner of the dam: laying and welding are special circumstances and they must be specially cut according to the actual conditions to make the sealing track close to the dam base, otherwise this leads to a "hanging". "or"exploitative"phenomenon.
Construction points: In this area, the operator must carefully measure the HDPE Geomembrane and cut it into an inverted trapeze with a wide top and a narrow bottom.
2. At the intersection point of the gap of the reservoir area and the reservoir floor there are often dead ends in the construction.
Construction points: First place the HDPE Geomembrane along the steam surface 1,5 meters from the blind ditch
Then connect to the lower membrane of the library; the welding of the two adjacent plates is: first weld and then press in the blind trenches.
1. If the length of the HDPE Geomembrane is not sufficient, it must be stretched in a longitudinal direction. First the cross-weld seam, then the longitudinal seam should be welded. The distance between the cross-welding seams is more than 50 cm and should be T-shaped and not cross.
2. The adjacent HDPE Geomembrane welding seams should be replaced and overlapped as far as possible. The joints formed between the membrane blocks should be T-shaped and the cross shape should be minimized. The intersection point of the longitudinal nozzle and weld seam should be reinforced with a continuous welding device.
3. When welding the film, no dead arches shall be pushed out. When installing the HDPE sealing track, consider the expansion and contraction caused by temperature changes according to the local temperature range and the performance requirements of the HDPE sealing track.
4. If the temperature of the welding device indicated by the temperature controller of the portable welding device is lower than 200℃, wipe it with a clean cloth or cotton yarn and solder it again. If necessary, drag it down and avoid rubbing it with your hands.
Having read this, I think you have some understanding and a judgment as to whether you need to order HDPE Geomembranes. The existing Feicheng Lianyi Plastic Co., Ltd. has been focused on the production of HDPE Geomembranes for over ten years.
