If the shaft head of coating machine is worn, the traditional repair methods include surfacing, thermal spraying, brush plating, etc., but there are some disadvantages, that is, surfacing will make the surface of parts reach a very high temperature, cause deformation or cracks, and even lead to shaft fracture in serious cases; the electroplating coating 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. For the material, it has very good adhesion and compressive strength, which can avoid disassembly. At the same time, because it has the concession of the lack of metal, it has the concession of the lack of metal, which can well absorb the impact and vibration of the equipment, and avoid secondary wear.
Due to the influence of corrosion, aging, equipment vibration and other factors, the coating machine will also cause damage to the concrete base and other parts, resulting in the loosening of the bolts of the fastening equipment, which seriously affects the production. The traditional concrete pouring method will greatly prolong the repair time, which is difficult for enterprises to accept. Polymer composite material also solves this problem well. The impact resistance and compressive strength of the material itself are far greater than that of the current concrete material. At the same time, it also adheres to the steel and other rough surfaces, and can be solidified quickly. It is a new scientific research achievement to repair the damage of the concrete base of the coating machine.
