In the underground mining industry, low creep elongation of the cc56 conveyor belt. frame material is very important. This is because the underground space is limited and large-scale tensioning devices cannot be equipped. For power flat belts running at high speed, the temperature of the belt body is easy to rise. Therefore, it is particularly important to maintain sufficient tension at high temperatures. .

cc56 conveyor belt are often used outdoors, so the moisture in the outdoor environment also has a serious impact on the creep elongation of the skeleton material: the standard retrospective rate of cotton fiber is 4.5%, cotton yarn is 8%, and polyester is only 0.3% . After the skeleton material absorbs water, the water becomes a plasticizer, which can make the material easier to stretch and reduce the modulus. The elongation at break increases. Obviously materials with less water absorption are more stable.

Water absorption will also cause the bonding interface between the rubber and the skeleton material, as well as the bonding interface strength between the RFL resin layer and the fiber impregnated by the skeleton material, which will reduce the peel strength between the layers and affect the service life of the cc56 conveyor belt.
