Coating of drying cylinder
tianmeng
The following are some main advantages:
1. Enhance wear resistance: Thermal spraying can use wear-resistant materials such as nickel-based alloys and tungsten carbide to form a solid coating on the surface of the drying cylinder, significantly improving its wear resistance, reducing surface wear caused by long-term operation, and extending the service life of the drying cylinder.
2. Enhance corrosion resistance: In the papermaking industry, acidic and alkaline media, steam and water vapor can cause corrosion to the drying cylinders. However, by applying a layer of corrosion-resistant materials such as stainless steel or nickel-based alloys through thermal spraying, the corrosive media can be effectively isolated, protecting the drying cylinders from erosion.
3. Improve thermal conductivity: By using materials with good thermal conductivity, such as aluminum and copper, for thermal spraying, the heat transfer efficiency of the drying cylinder can be enhanced, the drying speed of paper can be accelerated, and productivity can be increased.
4. Repair and Renovation: For old or slightly damaged drying cylinders, thermal spraying technology can be used for local or overall repair, restoring dimensional accuracy and flatness, saving the cost of replacing new drying cylinders, and achieving effective utilization of resources.
