Abstract

The invention provides a polishing treatment technology for a stainless steel packaging box. The polishing treatment technology comprises the following steps of carrying out oil removal; carrying outwashing in flowing water; carrying out acid pickling; carrying out water washing; carrying out electrochemical polishing; carrying out cold water cleaning; carrying out chemical passivation; and carrying out drying. The polishing treatment technology has the advantages that the problem that in the prior art, the original color and lustre of the stainless steel packaging box is damaged due to external reasons can be solved, the surface of a part can be guaranteed to reach the smoothness degree of a mirror plane, the service life of an electrochemical polishing solution can be prolonged, and thequality stability of the stainless steel packing box can be ensured.

Description

technical field [0001] The invention relates to the field of chemical polishing of metal surfaces, in particular to a polishing process for stainless steel packaging boxes. Background technique [0002] Human society is constantly progressing, and there are more aesthetic choices. In some packaging fields, people choose to use various metals to decorate stainless steel packaging boxes or stainless steel packaging boxes to hold some food and cosmetics. Stainless steel packaging boxes are exposed to the atmosphere or are in contact with the atmosphere. After human sweat is in contact, it will gradually change color as time goes by. The degree of corrosion mainly depends on the pollutants, humidity and temperature in the environment, and is also related to the atmosphere, such as the climate in the south or north, industrial atmosphere or marine atmosphere. Etc., the metal discoloration situation is also quite different, and the way to prevent corrosion discoloration is the pro...
