a. The corrosion of the double-shaft paddle dryer is mainly due to the fact that the double-shaft paddle dryer is made of metal, and the chemical activity of the metal is relatively high. When the metal is exposed to humid air for a long time, the metal will Oxidation occurs, and eventually corrosion occurs. The two-shaft paddle dryer is made of different metal materials, and their ease of oxidation reaction is different.
b. The purer metal made of double-shaft paddle dryer is less likely to be corroded. When there are more impurities in the metal, the double-shaft paddle dryer will be more easily corroded.
c. When the shape of the parts inside the double-shaft paddle dryer is more complex and the surface is rougher, the corrosion resistance will be worse. When the internal parts corrode, it will soon cause damage to the parts. The metal where it comes in contact also corrodes, and it corrodes very quickly.
d. When the working environment of the double-shaft paddle dryer is high in temperature and humidity, or if there are many oxygen and chloride ions in the environment, it is easy to have a chemical reaction with the double-shaft paddle dryer and accelerate the operation of the double-shaft paddle dryer. degree of corrosion.
