Dryer mesh belt material selection performance characteristics

The dryer mesh belt is a friction-driven machine that transports materials in a continuous manner. There is a passivation film on its surface. In actual use, there are many factors that will damage the passivation film of the dryer mesh belt. Once this passivation film is damaged, the passive state of the stainless steel will be converted into an active state, resulting in a decrease in the corrosion resistance of the stainless steel, which in turn reduces the service life of the stainless steel dryer mesh belt. For stainless steel dryer mesh belts, the lower the surface roughness, the smoother the surface, the more difficult it is for foreign matter to attach, and the lower the probability of local corrosion of each part. Therefore, the dryer mesh belt should use a fine-machined surface as much as possible. In addition, the cleanliness of the stainless steel surface is also very important. The final cleaning after passivation should be carried out carefully, because the residual acid promotes the cathode reaction, causing the film layer to rupture, thereby activating the stainless steel and drastically reducing the corrosion resistance.
