Description

A cleaning method and system for avoiding cavitation corrosion of cutting tools

【Technical field】

The invention relates to the technical field of metal materials, in particular to a cleaning method and system for avoiding cavitation corrosion of cutting tools.

【Background technique】

Industrial production kitchen knives must be cleaned before they can enter the market. Ultrasonic cleaning uses the cavitation of ultrasonic waves to impact and peel off the dirt on the surface of the object to achieve the purpose of cleaning. Ultrasonic cleaning has the characteristics of high cleanliness and fast cleaning speed. Therefore, the combination of ultrasonic cleaning agent and water is usually used for cleaning in industry. Although ultrasonic cleaning reduces the cost and improves the efficiency, the thickness of the blade of the kitchen knife is only a dozen or even a few microns. During the cleaning process, the blade is cavitated and corroded, causing the blade to become dull and sharpness to decrease. Cavitation corrosion refers to the phenomenon of damage to the solid surface caused by the collapse of the cavitation formed in the liquid existing on the solid surface and resulting in a strong impact force. The document "Effect of Ultrasonic Cleaning on Cavitation Corrosion of Aluminum Parts" shows that aluminum alloy parts have different degrees of cavitation corrosion and even pitting corrosion marks during the ultrasonic cleaning process. Therefore, it is very important to keep the blade of the kitchen knife free from cavitation corrosion during the ultrasonic cleaning process, which is related to one of the most important properties of the kitchen knife - the maintenance of sharpness.

At present, the industry mainly uses the combination of ultrasonic wave and clean water for cleaning, which produces cavitation corrosion on the cutting edge, which causes the cutting edge to become dull and the sharpness decreases.

Therefore, it is necessary to study a cleaning method and system for avoiding cavitation corrosion of tools to deal with the deficiencies of the prior art, so as to solve or alleviate one or more of the above problems.
