The welding of the impermeable geomembrane is a very critical node in the whole project. If the welding is not good, it will directly affect the quality of the entire project. Therefore, we must have strict regulations on welding to reduce unnecessary losses.
Before the anti-seepage geomembrane is welded, the surface of the membrane should be cleaned, and the dust or sand on the surface of the membrane should be wiped off with a rag. After cleaning, start welding. Special attention should be paid to the overlapping width of the weld bead should always be maintained at 80-100mm;
The natural folds of the plane and vertical surface should be 5%-8%; (2%-5%) residual amount of scrap; (3%-5%) pre-reserved expansion. If the anti-seepage geomembrane is thick, it is recommended to choose a large welding machine.
Anti-seepage geomembrane is widely used in anti-seepage projects, and more and more used in modern agriculture and animal husbandry. In arid areas and water-deficient areas, the use of anti-seepage geomembrane can effectively improve the utilization rate of water.
Geomembrane manufacturer--- Gerui group will explain to you the welding of anti-seepage geomembrane, as follows: the welding part is an extremely important part in the construction of geomembrane, first of all, to ensure the stability of the voltage, and secondly to pay special attention to the strength of the welding.
Because the surface is not smooth, the welding machine moves slowly when welding on the film. As we all know, the non-smooth anti-seepage geomembrane can play a non-slip effect by using the principle of friction, and the friction coefficient is large.
This anti-slip effect is very practical in project application. In the design of the non-smooth anti-seepage geomembrane, both ends of the membrane are designed as smooth surface layers, and only welding on the sliding surface layer can obtain a good welding actual effect.
The smooth surface design at both ends of the membrane not only has a strong practical effect of welding, but also has a faster speed, which reduces the difficulty of operation and improves the work efficiency of the project.
HDPE geomembrane is made from high grade polyethylene raw material,adding carbon black,antioxidant,anti-aging and UV resistance component.It adopted the first class automatic production equipment and three-layer pressing technology.All products are in accordance with GB/GRI/ASTM standard.
Our HDPE geomembrane is made of 100% raw material hdpe which is imported from USA company in Middle East. After testing,the quality meets the ASTM standard completely.(0.5 or 0.75mm-thickness is used for pond liner,1.5mm-thickness is used for landfill,2.0mm-thickness is used for dam liner.)
Gerui Group basically provides the right priced products and serves the customer’s needs, requirements and expectations.
