When the blade dryer is used for a long time, the blade dryer will appear the phenomenon of corrosion, then, what is the cause of this phenomenon?

• • A the corrosion of the biaxial blade dryer is mainly due to the fact that the production material of the biaxial blade dryer is metal, and the chemical activity of metal is relatively high. When the metal is exposed to humid air for a long time, the metal will undergo oxidation reaction, and then there will be corrosion. The metal materials of the two shaft blade dryer are different, and their oxidation reaction is different.
  • B The more pure the metal, the less likely the biaxial blade dryer is to be corroded. The more impurities in the metal, the more likely the biaxial blade dryer is to be corroded.
  • C when the shape of the parts inside the two-shaft blade dryer is more complex and the surface is more rough, then its corrosion resistance is worse. When the corrosion of the internal parts occurs, it will soon cause the metal in contact with the parts to corrosion, and the corrosion rate is very fast.
  • D when the working environment of the biaxial blade dryer is high in temperature and humidity, or there are more oxygen and chloride ions in the environment, it is easy to have a chemical reaction with the biaxial blade dryer, and accelerate the corrosion degree of the biaxial blade dryer.

Our company has successfully applied wet-resistant, corrosion-resistant and high-temperature tungsten carbide coating to the blade shaft, blade and tank of sludge dryer made by Mitsubishi Heavy Industries in Japan through supersonic spraying, which has greatly improved the service life of the parts after continuous use and tracking by customers.
