[0028] b. Preparation of zirconium-based conversion liquid: add 1-7g / L zirconating agent, 2-8g / L oxidizing agent, 0.2-10g / L complexing agent and 0.2-1.5g / L accelerating Agent, mix evenly and let stand;
[0029] c. Preparation of zirconium-based conversion film: Put the prepared zirconium-based conversion liquid in a container, add a pH regulator dropwise at room temperature to adjust the pH value of the zirconium-based conversion liquid to 3.8-4.2, then add water to a constant temperature water bath, and Place the container containing the zirconium-based conversion solution in a water bath and heat it. When the zirconium-based conversion solution reaches 23-27°C, keep the temperature constant, and hang the pretreated substrate in the zirconium-based conversion solution for zirconization treatment for 1-5 Minutes, the zirconium-based conversion solution is continuously stirred during the treatment process, the substrate is taken out after the treatment is completed, washed with...
