I. Membrane Fabric Heat Sealing Process
High-Frequency Heat Sealing Technology: This technology uses a high-frequency electromagnetic field to generate heat through friction between membrane molecules, achieving fusion welding.
Test Piece Testing: Before formal welding, test pieces (220mm × 50mm) must be prepared. Tensile tests are conducted to verify the weld strength. If the weld is intact and the strength meets the standard, the process is considered合格 (qualified).
II. Weld Treatment and Inspection
Visual Inspection: Check if the weld is smooth, free of bubbles or scorch marks.
Sealing Test: Air tightness: Leakage rate, meeting the pressure requirements of the inflatable membrane structure.
Weather Resistance Test: Simulate environments such as ultraviolet radiation and high temperatures to evaluate long-term performance changes.
