The transmission part of coater is worn

　　The bearing of the coating machine and the dryer will be worn during the operation, such as the wear of the shaft of the coating machine. The traditional repair methods include surfacing, thermal spraying, brush plating and so on, but they all have some disadvantages: surfacing will make the surface of parts reach a very high temperature, cause deformation or crack, and even lead to shaft fracture in serious cases; The plating layer can not be too thick, and the pollution is serious, and the application is also limited. With the development of technology, polymer composites can be used to solve the above problems, among which meijiahua technology system is more mature. The material has good adhesion and compressive strength, which can repair the wear of the coater on site without disassembly. At the same time, because it has the concession of lack of metal, it can well absorb the impact and vibration of the equipment and avoid secondary wear.

　　The concrete foundation of the coater is damaged

　　Due to the influence of corrosion, aging, equipment vibration and other factors, the coater will also cause damage to the concrete base and other parts, resulting in the loosening of the bolts fastening the equipment, which will seriously affect the production. The traditional concrete pouring method will greatly prolong the repair time, which is difficult for many enterprises to accept. Polymer composites also solve this problem well. The impact resistance and compressive strength of the materials themselves are far greater than the current concrete materials. At the same time, they also adhere to steel and other rough surfaces and can be cured quickly. It is a new scientific research achievement to repair the damage of the concrete base of the coater.
