Post-heat-sealing Inspection Items for Membrane Structure Fabric:
Appearance Inspection: Check for smooth welds, free of bubbles, wrinkles, or impurities, ensuring no incomplete or missed welds.
Dimensional Inspection: Measure heat-sealed dimensions and errors.
Strength Inspection: Test tensile strength through a tensile test.
Sealing Inspection: Check the watertightness of welds to ensure no leakage.
Weather Resistance Inspection: Simulate ultraviolet radiation, high temperature, and other environments to assess long-term performance changes.
Testing Methods:
Physical Testing: Measure tensile strength using a tensile testing machine.
Auxiliary Instruments: Thickness gauge, air permeability tester, etc.
Precautions:
The testing environment must meet standards.
Clean the membrane surface after testing to avoid scratching the coating.
