Welcome to call for consultation! This is a good intention and a dream, only left to try spring tea in Zhuang Sheng's dream, with a diamond ring and a heart, 【156-2152-1000】; Loving green, planting green, and protecting green is the foundational project to enhance the core competitiveness of cities, as well as a project that benefits the general public, which must be genuinely implemented. We must take out the momentum of breaking ground to plant and protect green.
Ruijin Drainage Board Manufacturer Welding of Plastic Drainage Boards:156-2152-1000 Manager Shao
1. The welding procedure for the hot wedge welding machine includes: adjusting pressure, setting temperature, setting speed, checking overlap of weld seam, entering film into the machine, starting the motor, and applying pressure for welding. KKolps33378
2. There should be no oil stains or dust at the seam; the overlapping section of the HDPE geomembrane should not contain sand or other debris. Ruijin Drainage Board Manufacturer must be cleaned before welding if there are foreign objects.156-2152-1000 Manager Shao
3. At the beginning of welding each day, a test weld of a 0.9mm×0.3mm sample must be made on-site, with an overlap width of no less than 10cm, and a peel and shear test should be conducted on-site using a tensile machine. Once the sample passes, formal welding can proceed at the previously adjusted speed, pressure, and temperature. The sample should be marked with the date, time, and ambient temperature. During the welding process, the hot wedge welding machine should be monitored for operation, and speed and temperature should be fine-tuned according to on-site conditions.
4. The weld seam should be neat and aesthetically pleasing, with no slipping or skipping.
5. When the length of the geomembrane is insufficient and longitudinal splicing is required, the transverse seams should be welded first, followed by the longitudinal seams. The distance between transverse seams should exceed 50cm and should form a T-shape, without crossing in a cross shape. KKolps33378
6. Adjacent geomembrane seams should be staggered, with junction points forming a T-shape, minimizing cross shapes. The intersection points of the longitudinal seams should be reinforced with an extrusion welding machine.156-2152-1000 Manager Shao
7. No dead folds should be pressed out during membrane welding. When laying HDPE geomembranes, reserve the amount of expansion and contraction caused by temperature changes according to local temperature variations and HDPERuijin Drainage Board Manufacturer geomembrane performance requirements.
8. When the temperature indicated by the hand-held welding machine is below 200℃, clean the surface with a clean cloth or cotton yarn before welding. If necessary, it should be re-polished, avoiding wiping with hands. 156-2152-1000 Manager Shao
9. If there is condensation, moisture, or sand affecting the seams, it must be treated before welding. 10. Welding should not be conducted during rain or when there is moisture, dew, or large amounts of sand at the seams, unless protective measures are taken.
11. If the temperature is below 5℃, construction should not be performed according to specifications. If construction is necessary, the welding machine should be preheated before welding. Ruijin Drainage Board Manufacturer
12. The extrusion welding machine should be regularly checked during the welding process for the sliding blocks. If there is severe wear, the blocks should be replaced promptly to avoid damaging the membrane surface. 156-2152-1000 Manager Shao
13. When welding the geomembrane, a generator with good voltage stability should be used for power supply. In special cases where local electricity is used, a voltage stabilizer must be employed.
Data shows that air energy is a widely available, equally distributed, and freely usable low-grade energy source. Heat pump technology uses the reverse Carnot cycle principle to absorb low-temperature thermal energy from the air with minimal electrical energy through the heat pump working fluid. After being compressed by the compressor, it becomes high-temperature thermal energy and is transferred to water to heat hot water. This is a highly promising energy-saving and environmentally friendly new technology. Industry insiders say that heat pump technology can consume less electrical or mineral energy, transferring and storing low-grade energy for people's use, achieving energy-saving and environmental protection effects.156-2152-1000 Manager Shao
