During the operation of the coating machine, the problem of wear of the transmission parts often occurs, such as the wear of the drying cylinder shaft head of the coating machine and the wear of the bearing chamber of the reel roll. Traditional repair methods include surfacing, thermal spraying, brush machine for wood plating, etc., but they all have certain drawbacks. Surfacing welding will make the surface of the part reach a very high temperature, causing deformation or cracks, and in severe cases, it will also lead to the fracture of the shaft. The electroplating layer cannot be too thick, and the pollution is serious, and the application is also limited.
With the development of technology, polymer composite materials can be used to solve the above problems at present, among which the more mature application is the Meijiahua technology system. The material has good adhesion and compressive strength, which can repair the wear of the coating machine on site without disassembly. At the same time, because of its concessional property of lack of metal, it can well absorb the shock 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 that fasten the 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 materials also solve this problem very well. The impact resistance and compressive strength of the material itself are far greater than the current concrete materials, and it also adheres to steel and other rough surfaces, and can be cured quickly. It is a new scientific research achievement in repairing the damage to the concrete base of the uv coating machine for sale.
The coating machine exists as a necessary high-power equipment, and its main energy consumption is concentrated in the drying process. Whether the drying process is reasonable or not directly determines the quality of the dried product, the energy consumption of the drying process, the length of the drying time and the production safety.
At present, some factories have adopted ways of reducing the amount of fresh air supply, using secondary return air, and using superconductors for heat exchange to save energy. However, this operation effect is not the best way to save energy. On the contrary, the dried product is slightly wrinkled, or the drying time is prolonged, or there is a danger of explosion. Therefore, it is more necessary to find more innovative technologies to improve the coating process. As the so-called open source and cost-saving, energy saving and emission reduction, and cost reduction are necessary strategies for the development of an enterprise, choosing the appropriate method and suitable energy-saving equipment to cooperate with the main production equipment is also a strategy of gathering sand into a tower, and it is also a sign of the development of an enterprise.
