Some industries require the conveyor belt to have heat-resistant characteristics, and there are certain differences in temperature resistance for heat-resistant conveyor belts of different materials. This makes many people have a headache when choosing heat-resistant conveyor belts. Today's conveyor belt manufacturers analyze the temperature-resistant interval of different material heat-resistant conveyor belts and how to choose them.
The temperature resistance range of PVC material is: -10 ℃ —— + 80 ℃; the maximum temperature resistance of conveyor belt made of rubber is 130 ℃; the maximum temperature resistance of conveyor belt made of PE is 100 ℃; the maximum temperature resistance of PU material is 80 ℃ ; The maximum temperature resistance of the conveyor belt made of silicone is 200 degrees Celsius. The best temperature resistance of all conveyor belts is Teflon.
1. Choosing the most suitable strap depends not only on thermal strain, but also on chemical mechanical stress;
2. The temperature of the conveyed material and the surface temperature of the belt change according to the composition, properties, surface structure shape and particle size of the material. For example, when the temperature of the bulk material is 150 ° C (coke or sintered ore) and compared with the contact area of the belt For hours, the surface temperature of the tape can be maintained at 60 to 80 ° C. However, when conveying cement powder, the difference between the material temperature and the surface temperature of the belt is small;
3. The life of the heat-resistant conveyor belt is greatly affected by the temperature of the surface of the tape, and it affects the rubber cover falling off and the belt core being delaminated. Therefore, when selecting the tape, it is extremely important to consider the surface temperature of the tape, as well as the ambient temperature. Whether it can be sufficiently cooled when returning; belt speed and center distance are notable;
4. Thicker cover rubber is an important condition to ensure long life of the tape. We recommend the cover rubber thickness of fabric core heat-resistant belt: upper cover 6 ~ 8mm, lower cover 2 ~ 4mm.
