When we process products, we generally use mechanical polishing, chemical polishing, electrochemical polishing and other methods to achieve mirrorstone luster according to the complexity of stainless steel products and user requirements.
Here are the advantages and disadvantages of the three methods:
Mechanical polishing: good leveling, bright labor intensity, serious pollution, complex parts difficult to process, luster decline, investment and cost of high simplex
Pieces, medium, small products, complex parts can not be processed. The luster of the whole product is not consistent, and the luster retention time is not long
Chemical polishing: less investment, complex parts can be thrown, high efficiency, fast speed, insufficient brightness, polishing liquid to humidify, gas overflow, need for wind
Equipment. Complex products, brightness requirements are not high products can choose small batch processing more cost-effective
Electrochemical polishing: mirror luster, long-term maintenance, process stability, less pollution, low cost, good pollution prevention. Large one-time investment, complex parts to install tooling, auxiliary electrodes, mass production to cool pollution products, requiring a long time to maintain mirror light, bright products. Stable process, easy to operate,
Can be widely promoted use
Stainless steel coloring not only endowed with various colors of stainless steel products, increase the variety of products, and improve the wear resistance and wear resistance of products.
Stainless steel coloring methods are as follows:
Ion deposition oxide or oxide.
2 high temperature oxidation method.
Chemical oxidation method.
Electrochemical oxidation.
Gas phase cracking
A brief overview of the various methods is as follows:
1 ion deposition oxide or oxide method, that is, stainless steel workpiece in vacuum coating machine for vacuum evaporation plating:
For example: titanium plated hand case and watch strap. It is usually golden yellow. This method is suitable for processing large quantities of products. Because investment is big, cost is high, small batch product is uneconomical.
2 High temperature oxidation method is in a specific molten salt, immersed in the workpiece to maintain a certain range of technology, so that the workpiece forms a certain thickness of oxide film, and presents a variety of color.
3 chemical method is in a specific solution, through chemical oxidation to form the color of the film, generally have “because can be used more, but to ensure the consistency of a batch of products, it must be controlled by reference telegraph.
The electrochemical method, which is used in a particular solution by electrochemical oxidation to form the color of the film, is used in this commercial application.
Gas phase cracking method is more complex and seldom used in industry.
Mechanical polishing, chemical polishing, electrochemical polishing and other methods can be used to achieve mirror stone luster according to the complexity of stainless steel products and user requirements.
