Introduction: The open mill may experience bearing chamber wear and tear due to vibration impact and other composite forces during production operation. How to solve this problem?



Traditional methods include welding, thermal spraying, and electric brush transfer



However, all of the above methods have certain drawbacks:



1. The thermal stress generated by high temperature welding cannot be completely eliminated



2. Easy to cause material damage, resulting in bending or breakage of components;



3. Electric brush plating is limited by the thickness of the coating and is prone to peeling off. Both methods use metal to repair the metal and cannot change the "hard to hard" fit relationship. Under the combined action of various forces, it will still cause further wear and tear



Lina often uses polymer composite materials as a repair method for the above problems, and the most widely used is the 1st line technology system in the United States, which has super strong adhesion, excellent compressive strength and other comprehensive properties. It can be disassembled and machined without welding or thermal stress, and the repair thickness is not limited. At the same time, the metal material of the product does not have the retreat ability, which can absorb the impact and vibration of the equipment and avoid the possibility of further wear.
