Regenerator 2~5g/L.
Wherein, described etching promotor is preferably hydrogen peroxide; Described regenerator is preferably hypochlorous acid; Described thiocarbamide is as inhibiter and anti-lateral erosion agent.
In addition, another object of the present invention then is to provide a kind of stainless steel etching technique, and its technology is simple, and is easy to operate.
Chemical milling is to utilize the corrosive nature of chemical solution that unwanted metal is dissolved the process of removing fast by chemical reaction.
This kind stainless steel etching technique provided by the invention, its step is as follows substantially:
1. pre-treatment, it mainly comprises steps such as degreasing, activation, it is in order to clean initial stainless steel work-piece, to remove the wet goods cleaning surfaces;
2. coating, this step can comprise steps such as making luxuriant and rich with fragrance continuous heavy rain, exposure imaging, making web plate, silk-screen, and, carry out the exposure of photoresists according to the processing pattern more normally with its surface-coated photoresists of the stainless steel work-piece after the above-mentioned processing, then develop and the post bake processing;
3. etching, the exposing metal position that utilizes the stainless steel etching solution of above-mentioned preparation to corrode this stainless steel work-piece;
4. demoulding is treated above-mentioned eroding to a certain degree, its surperficial remaining glued membrane is removed with lysate again, and last water cleans up and obtains etching and processing workpiece product.
Therefore, stainless steel etching technique provided by the invention merges stainless activation and etching and carries out, make technology become simpler, in addition, in the stainless steel etching solution, add etching promotor, to accelerate etching speed, cooperate again simultaneously and add suitable inhibiter and anti-lateral erosion agent, improve precision, add regenerator again, make this etching solution repeatedly to use.Thus, it is fast that this technology has etching speed, the precision height, and characteristics such as etching solution is renewable, and processing procedure is simple are with a wide range of applications.
