The main difference between chemical degreasing and electrolytic degreasing lies in their basic principles and operation methods.
Chemical degreasing is the process of removing oil stains on the surface of parts by using the saponification and emulsification of hot alkaline solution on grease. This method mainly relies on the action of alkaline substances (such as sodium hydroxide, sodium carbonate, etc.) and surfactants to remove oil stains through saponification reaction and emulsification. The advantages of chemical degreasing are simple process, easy operation and low cost, but the degreasing effect may not be as thorough as electrolytic degreasing.
Electrolytic degreasing is the process of using electrolysis to enhance the degreasing effect. In an alkaline solution, the part is used as the anode or cathode, and the gas (hydrogen and oxygen) generated by electrolysis is stirred by direct current to remove oil stains and promote the emulsification process. The advantages of electrolytic degreasing are fast speed and good effect, but it requires more complex equipment and operating conditions, and there are safety hazards.
In summary, chemical degreasing is suitable for small batches and simple degreasing needs, while electrolytic degreasing is suitable for large batches and high-quality degreasing requirements. Although electrolytic degreasing is more expensive and complicated to operate, it has a more thorough degreasing effect and is particularly suitable for high-demand industrial production environments.
