Background
The insoluble Ti-base anode is one with Ti as matrix and surface of Ti matrix as anode material with catalytically active coating. In the electrochemical process, the titanium anode has good corrosion resistance and higher catalytic activity, can keep stable size and shape in the electrolytic process, and has been widely applied to the fields of electroplating, chlor-alkali industry, wastewater treatment, organic synthesis, cathodic protection and the like.
In the pretreatment step in the titanium anode production process, cutting, sand blasting, thermal calibration, acid cleaning, brushing and sintering are usually performed in a minor order. For a titanium anode with a thickness of 1mm, since the substrate is a titanium plate with a thickness of 1mm only, deformation of the titanium plate is often caused in the sand blasting process, thereby causing the following problems: (1) the titanium plate is often required to be subjected to repeated thermal correction treatment for many times after sand blasting, so that the production efficiency is reduced; (2) multiple times of thermal correction treatment can enable thicker titanium oxide skin to be formed on the surface of the titanium plate, so that the subsequent pickling step needs to be carried out for multiple times, the oxide skin can be cleaned, and the production efficiency is reduced.

(3) Performing cold correction treatment on the titanium matrix processed in the step (2);
(4) Performing thermal correction treatment on the titanium matrix treated in the step (3);
(5) Performing laser cleaning treatment on the titanium matrix treated in the step (4);
(6) And (3) carrying out acid washing treatment on the titanium substrate treated in the step (5).

Preferably, the sand blasting method in the step (2) is any one of manual sand blasting and automatic sand blasting.
Preferably, the cold-forming in the step (3) is performed by using a forming machine, the number of pressure points of the forming machine is 4-20, the pressure range is 0.3-1 Mpa, and the rotating speed of the roller is 50-300 r/min.

2. The invention performs the calibration treatment of the calibration machine before thermal calibration, namely, external pressure is applied by a mechanical method, so that the titanium matrix after sand blasting can be initially calibrated to reach a relatively flat state; on the one hand, the titanium matrix can be better overlapped and placed during thermal correction, so that a better thermal correction effect is achieved; on the other hand, the number of times of thermal correction can be reduced, the production time is greatly reduced, and the production efficiency is improved; in addition, thicker oxide skin is avoided from being generated due to multiple times of thermal correction, so that the frequency and time of subsequent pickling treatment are reduced, and the production efficiency is improved.
3. According to the invention, the titanium substrate after thermal calibration is subjected to laser cleaning and descaling treatment, and under the condition that the roughness of the titanium substrate is not affected, the scale on the surface of the titanium substrate is cleaned and removed, so that the subsequent time for pickling and removing the titanium scale is reduced, and the production efficiency is improved.
