In the domestic single-layer waterproofing membrane roofing project,TPO waterproofing membrane is increasingly used in roofing.During the construction of the project site,there are many factors affecting the welding and peeling strength of TPO coil,but the most important factors are human factors,such as the temperature and speed of hot air welding machine commis-sioning,the operation proficiency of construction personnel,the contamination of TPO coil,etc..Of course,the site environmental sit-uation is also one of the factors affecting welding strength.In order to ensure the seam peeling strength of the coil,the hot air welding machine needs to maintain a suitable temperature and speed during welding,keeping the surface of the coil clean,dry and pollution-free,avoiding construction in bad weather.
