Repair method of polymer composite material for mill roller bearing wear

It has super adhesion, excellent compressive strength, wear resistance and corrosion resistance and other comprehensive properties.
The use of polymer composite materials can be repaired without disassembly on site when the wear size of the transmission part is relatively small. It not only avoids mechanical processing, but also has no thermal stress and thermal influence of repair welding, and the repair thickness is not limited.

At the same time, the wear resistance of the product and the concessionality that metal materials do not have, ensure 100% contact cooperation of the repaired parts, reduce the impact and vibration of the equipment, and avoid the possibility of wear.

And greatly prolong the service life of equipment components (including bearings), save a lot of downtime for enterprises, and create huge economic value.

Cold welding repair method: The cold welding machine uses the principle of electric spark high-frequency discharge to perform heat-free surfacing welding on the metal surface, so it does not deform, anneal, undercut and residual stress in the process of repairing roll blisters, scratches and other defects. Does not change the state of metal organization.

The repairing precision is high, and the coating thickness is from several microns to several millimeters. It can deposit, seal, fill and repair defects such as wear, scratches, pinholes, cracks, defect deformation, hardness reduction, trachoma, damage and other defects in metal workpieces. , It only needs to be ground and polished, and it can also be used for various types of mechanical processing such as turning, milling, planing, and grinding, as well as post-processing such as electroplating.
