[0021] The following is a detailed description of the specific implementation process of reducing the fluorine residue on the pickling surface of the nuclear zirconium alloy tube with a specification of Ф13×1mm. The specific implementation steps are:
[0022] a) with NH 4 HCO 3 Solution immersion, the Ф13×1mm zirconium alloy tube after pickling is immersed in NH at a constant speed at an angle of about 45 degrees between its length direction and the horizontal plane 4 HCO 3 After being in the solution, swing up and down, and the soaking time is 75 seconds, of which NH 4 HCO 3 The volume ratio of each component in the solution is: NH 4 HCO 3 : Demineralized water = 1:10;
[0023] b) Rinse with NaOH solution, and use NH 4 HCO 3 The Ф13×1mm zirconium alloy tube after dipping in the solution is immersed in the prepared NaOH solution at a constant speed at an angle of about 45 degrees between its length direction and the horizontal plane, and then swings up and down.
