Specifically, after degreasing and acidification are carried out on the polished titanium product, an oxide film is removed, generation of spots and the like is avoided and reduced, and the quality of the oxidized and colored titanium product is improved.
In the present embodiment, the power supply for limiting the dc voltage stabilization of the electrolysis means is 10 to 55V, and 5V is used as the voltage interval. If the voltage is less than 10V, the early color change is slow, the color forming is poor, and the finished product efficiency is influenced, while if the voltage is more than 55V, on one hand, the voltage is too large, and the operation safety hidden trouble exists, and on the other hand, the color can be basically realized within the range, and the voltage is too large, so that the resource waste is caused.
