This kind of technology is relatively backward. The traditional hot vulcanized rubberized roller has low vulcanization pressure and high sulfur content. In addition, the rubberized panel has low rubber content, poor rubber wear resistance, and very short service life. It is easy to age, and the rubber will become hard after aging, which leads to the decrease of the adhesion between the conveyor roller and the belt, the cleaning function is degraded, the roller thermal encapsulation technology is backward, the operation is complicated, and the on-site construction operation cannot be performed. The cost of hot vulcanization is lower, and it is still the first choice of some manufacturers. During the hot vulcanization process, the pressure during vulcanization is somewhat low, causing the drum to be hot-packed, the wear resistance is not very good, and the long-distance transportation also causes a certain cost to the manufacturer, so the proportion of hot vulcanized rubber is increasing. less.
