TL;DR
This paper studies the best parameters for welding TPO waterproofing membranes to ensure strong and watertight seams in construction projects.
Contribution
The study determines optimal welding temperature, speed, and pressure for TPO membranes using peel and water impermeability tests.
Findings
The optimal welding temperature for TPO membranes is 400 °C, where peel strength is maximized.
The best welding speed is 4 m/min, and the optimal pressure is 14.97 N for strong seams.
The water impermeability test confirms the effectiveness of the optimized parameters under various pressure conditions.
Abstract
Taking the TPO waterproofing membrane as an example, this paper studies the influence of temperature, speed and welding pressure on the welding quality of a TPO waterproofing membrane lap area through a peel test and a water impermeability test, determines the optimal construction process, and observes and compares the permeable path through laser confocal microscope. Finally, it is applied to the actual effect test in the project. The results show that the welding pressure test tool for the lap area of the waterproofing membrane is designed to meet the welding work test requirements of various lap areas of the waterproofing membrane. The peel strength increases first and then decreases with the increase in welding temperature, and the optimal construction temperature is 400 °C. The optimal construction speed is 4 m/min; at 400 °C welding temperature, the peel strength increases first…
