Welding methods and advantages of PVC conveyor belts for special environments

I. Common Welding Methods for PVC Conveyor Belts \ n1. High-frequency welding: By using high-frequency current to generate heat inside the PVC material, the material molecules move vigorously, generating heat and melting, and the connection is achieved under pressure. For instance, in the plastic film packaging industry, high-frequency welding is widely used to quickly weld two layers of plastic film together to form a sealed packaging bag. The welding speed is fast and the efficiency is high. Generally, it only takes a few seconds to complete the welding of one weld point. The weld seam has high strength, good appearance quality and good repeatability. No additional welding AIDS are needed, simplifying the welding process.

2. Hot air welding: The connection area of ​​the PVC conveyor belt is heated by heating equipment such as a hot air gun to soften the PVC material, and then pressure is applied to fuse the two ends together, and a firm connection is formed after cooling. The equipment cost is relatively low, the operation is relatively simple, and it is easy to master; the requirements for materials are relatively low, and it is suitable for welding a variety of PVC conveyor belts.

2. Advantages of PVC conveyor belt welding for special environments

1. High efficiency: The welding speed is fast and the efficiency is high, which can significantly improve production efficiency. For example, high-frequency welding can complete welding in a few seconds, and the hot vulcanization joint method can also achieve firm bonding in a shorter time.

2. Firmness: The weld formed by welding has high strength, at least equivalent to the surrounding materials, or even stronger. For example, the toothed joint is the strongest joint method for PVC conveyor belts, and the joints after bonding are evenly stressed.

3. Environmental protection: PVC materials can be recycled and have little pollution to the environment. In industries such as food and medicine that require environmental protection and non-toxic certification, rubber/PVC/PU belt cold bonding glue can be used, without solvent volatilization, to avoid contamination of the production line.

4. Wide adaptability: The welding method is suitable for PVC conveyor belts of various thicknesses and textures, and can meet the needs of different industries and application scenarios. For example, hot melt connection, high-frequency welding and other methods can achieve a firm connection under special circumstances.
