Heat-resistant conveyor belts are often used in metallurgy, construction and other industries. Frequent transportation of coke, cement clinker and other materials will inevitably affect the service life of the conveyor belt. So what are the factors related to its service life? Next we will talk about several factors that have major impacts.
The surface temperature of the heat-resistant conveyor belt is closely related to the service life of the heat-resistant belt, which directly affects the bond strength between the cover rubber and the core layer and the core layer, the wear resistance of the cover rubber, and the crack resistance. For example, when conveying a large mass of sintered ore, coke, etc. at a temperature of 150 ° C, and the contact area of the material with the belt surface is small, the belt surface temperature is maintained at 60-80 ° C. When the conveyor belt transports materials with lower viscosity such as cement powder, the difference between the material temperature and the belt surface temperature is small.
The cover layer of the heat-resistant conveyor belt is made of EPDM rubber and the skeleton material is made of domestic special high-temperature resistant canvas. The unique formula design solves the problem of high saturation, poor adhesion and adhesion between ethylene propylene rubber. Low key issues. The conveyor belt is used under the condition that the material temperature does not exceed 800 ° C and the surface temperature does not exceed 220 ° C. Once it exceeds this range, it will definitely affect its life.
