Problems solved by technology

[0003] At present, the polishing of stainless steel metal products still uses the traditional mechanical polishing process. This polishing process is usually high-temperature pickling after degreasing. The pickling solution often contains chromic acid, hydrofluoric acid, nitric acid and other toxic substances. , the main function of the pickling solution is to remove scale and improve the finish of metal products, but the high-temperature pickling takes a long time, which not only makes the production cost high, but also the toxic acid contained in it is highly volatile, which is easy to pollute the environment and corrode equipment

Embodiment 1

[0019] A stainless steel polishing process, comprising the following steps:

[0020] (1) Surface stain cleaning: soak the stainless steel workpiece to be polished in acetone for 30 minutes, then take it out, rinse the surface with potassium bicarbonate solution for 5 minutes, and dry to constant weight;

[0021] (2) Ultrasonic cleaning: Soak the stainless steel workpiece treated in step (1) in sodium sulfite solution for 10 minutes, and then use ultrasonic treatment for 3 minutes. After taking it out, rinse the surface with deionized water for 3 minutes, and dry to constant weight;

[0022] (3) Surface activation: Put the stainless steel workpiece treated in step (2) into a closed impregnation tank, vacuumize the tank to -0.12MPa, then inject the activation solution into the impregnation tank, and immerse the stainless steel workpiece. Treat for 2 hours, then take out the stainless steel workpiece, rinse the surface with sodium carbonate solution for 3 minutes, and dry to cons...

Abstract

The invention discloses a polishing technology for stainless steel and relates to the technical field of stainless steel processing. The polishing technology comprises steps as follows: (1) surface stain cleaning, (2) ultrasonic cleaning, (3) surface activation and (4) chemical polishing. Compared with the prior art, the polishing technology has the advantages as follows: more environment-friendlymaterials are adopted, components of different action mechanisms are reasonably matched, and on the basis that environmental protection is guaranteed and the cost is reduced, a stainless steel product has the better mirror effect; and besides, deep surface flaws can be removed without advance machining with the preparation method, the apparent effect is improved, and the technology is simple.

Description

technical field [0001] The invention belongs to the technical field of stainless steel processing, and in particular relates to a stainless steel polishing process. Background technique [0002] With the improvement of people's living standards, stainless steel metal products are increasingly entering kitchen utensils, tableware, etc. in family life, which requires higher and higher requirements for stainless steel metal products. The appearance should be mirror-bright, delicate and pleasing to the eye. Most stainless steel metal products are processed by high temperature such as hot rolling, forging, heat treatment, welding, etc. During the processing, thick oxide skin will appear on the surface. In addition, due to the different geometric shapes of stainless steel metal products, the gray film produced during welding , black slag, etc. remain on the surface of metal products. For this reason, stainless steel metal products must be polished after processing. [0003] At p...
