Hot air welding is the method used by Himei waterproof tiles. This welding method uses a heat gun to heat the edges of the two TPO films on the edge of the Himei waterproof tile, and then press them together so that they melt and form a strong connection. This welding method ensures a tight seal at the joint and prevents moisture leakage.
1. Fusion performance: TPO is a thermoplastic polymer that can melt and re-solidify when heated. Through hot air welding, the TPO in the welding area is heated to a sufficient temperature to melt it and form a liquid state. As it cools, the TPO resolidifies, forming a strong connection.
2. Material compatibility: Hot air welding uses the same type of materials, ensuring material compatibility. Because the welding uses the same TPO material, they bond together better as they melt and solidify, forming a connection that reduces the potential for leaks.
3. No need to add additional materials: Hot air welding does not require additional auxiliary materials such as glue, adhesive or sealant. This reduces the risk of lamination between materials and leakage due to material differences. The segments in the welding area are fused together directly by heat, creating a more integrated connection.
4. Sealing: Welding provides a good seal because when welding, the hot air gun not only heats the material to a sufficient temperature, but also applies a certain amount of pressure to ensure that the molten segments are pressed together firmly to form a tight connection. .
