What aspects caused erosion in the hollow blade dryer?

Metal characteristics: The key to the corrosion of hollow blade dryers is that the raw materials of hollow blade dryers are metal materials, which have high organic chemical properties. When metal materials are exposed to damp and cold gases for a long time, they will undergo oxidation-reduction reactions and corrosion. The ease of oxidation-reduction reactions varies depending on the metal composite materials made by hollow blade dryers.

Composition of metal materials: The purer the hollow blade dryer made of metal materials, the less susceptible it is to erosion. The larger the residue in the metal material, the more susceptible the hollow blade dryer is to erosion.

Part surface: The more complex the internal parts of the hollow blade dryer, the less smooth the surface, and the poorer the corrosion resistance. When internal parts are corroded, the metal materials in the contact area with the parts will also be rapidly corroded, and the corrosion rate is very fast.

Natural environment: When the working temperature and humidity of the hollow blade dryer are high, or there are many oxygen and chloride ions in the natural environment, it is easy to undergo exothermic reactions with the hollow blade dryer, accelerating the corrosion level of the hollow blade dryer.
