Exploring the Durability of Heat-Resistant Conveyor Belts: Do You Know the Science Behind It?

Summary

Heat-resistant belts and rubber additives ensure durability in harsh environments.

Background
High temperature resistant conveyor belts are widely used in industries such as metallurgy, cement, and power generation for material transport in high-temperature environments. These belts need to possess characteristics such as high temperature resistance, wear resistance, high tensile strength, and chemical corrosion resistance. However, in actual use, excessively high material temperatures can damage the conveyor belt, significantly impacting its lifespan and operational efficiency. This issue has become a significant pain point in the industry and requires effective solutions.

To address the damage caused by high temperatures, the following solution is proposed:

Material Selection:
Use EPDM rubber as the covering layer of the conveyor belt. EPDM rubber offers excellent high-temperature resistance, maintaining stability even under extreme temperatures.
Structural Design:
The conveyor belt's skeleton material is made of high-temperature resistant EP fabric, which enhances the overall tensile strength, ensuring long-term use under high-temperature conditions.
Formula Optimization:
Through a unique formulation design, the solution addresses the key issues of poor adhesion and low interlayer bonding strength caused by the high saturation of EPDM rubber, ensuring a tight bond between the layers of the conveyor belt in high-temperature environments, thus improving overall durability.
Summary
By using EPDM rubber for the covering layer and high-temperature resistant EP fabric as the skeleton material, combined with a unique formulation design, the performance of the high-temperature resistant conveyor belt is significantly enhanced, extending its service life. This solution is particularly suitable for high-temperature material transport in industries such as metallurgy, cement, and power generation, effectively addressing the challenges posed by high-temperature environments and ensuring the efficient operation of the conveyor system.
