Whether a piece of equipment is operating normally, its key components play a very important role. The press roll is one of the more important parts in the paper machine. If there is a failure, it needs to be repaired in time to avoid delaying production.
During the operation of the equipment, the press roll of the paper machine is constantly washed by the material, and the problem of wear often occurs in the transmission part. Usually, the bearing part of the press roll is more worn. If it is not dealt with, the equipment has been worn all the time, it will cause damage to our equipment, which will affect the normal operation of our equipment.
In view of the phenomenon of wear on the press roll, the more traditional repair method is to use surfacing, thermal spraying, electroplating, etc., but they all have the disadvantage of being in different places. When repair welding, high temperature will produce thermal stress, there is no way to completely eliminate it, and the plating layer will also be subject to certain restrictions.
If we want to solve this problem, we must use polymer composite materials to solve. Because the material itself has better adhesion and compressive strength, it can be repaired without disassembly on site, which saves time and labor compared with traditional methods. Moreover, our polymer material has the concession of lack of metal, which can well absorb the shock vibration caused by the pressing roller during operation, reducing the probability of occurrence of secondary wear
