Reasons for choosing cold-bonded and hot-bonded joints for conveyor belts
Conveyor belt cold bonding and hot bonding are two very common joint methods, how to choose mainly depends on the following 4 points:
1. The type of conveyor belt determines whether hot-melt joints are required, and steel buckles should be used as conveyor belt joints. Depending on the situation, it can be hot-vulcanized, steel buckles, or cold-bonded. The thicker the better, the hot-melt head.
2. Width and length. Generally speaking, 1000mm is a limit. If the width is less than 1000mm, it can be cold bonded. If it is higher than 1000mm, it is better to heat vulcanize. Etc.
For example, we once glued 2200mm belt joints to Zhongneng Biopower Plant with cold bonding, and the effect is also very good. Generally speaking, if the total length of the conveyor belt is relatively long, choose thermal vulcanization bonding joints, and if it is relatively short, use cold bonding.
3. You can refer to the position of the conveyor belt. Some conveyor belts cannot be released from the vulcanizer, so choose cold-bonded joints.
4. You can refer to the transported materials, such as acid and alkali resistance, heat resistance, and relatively high density; it is better to choose heat-vulcanized adhesive joints for relatively high moisture.
