Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The main solutions of the embodiments of the present invention are: acquiring field information of a stainless steel weld joint and the surface to be treated; gear adjustment is carried out on processing equipment according to the field information, wherein the processing equipment comprises a grounding wire clamp, an operation brush head and an inverter; connecting the grounding wire clamp with the stainless steel welding seam and the surface to be treated, and switching on an operation power supply of the treatment equipment so as to enable the operation brush head to alternately change with the electrode of the stainless steel welding seam and the surface to be treated through an inverter in the treatment equipment; and brushing the pre-configured electrolyte on the welding seam and the surface of the stainless steel to be treated through the operation brush head so as to remove the oxides on the welding seam and the surface of the stainless steel to be treated and generate a passivation film. The electrolyte is coated on the stainless steel welding seam and the surface through the operation brush head of the treatment equipment, and electrodes between the treatment equipment and the stainless steel welding seam and the surface are alternately changed under the control of the inverter, so that the electrolyte decomposes oxides on the stainless steel welding seam and the surface, thereby having the deoxidization effect, and simultaneously, the passivation film is rapidly generated through the electrochemical reaction, so that the treatment efficiency of the stainless steel welding seam and the surface is improved.
The traditional pickling passivation process mainly adopts nitric acid with strong oxidizing property such as pickling passivation solution or pickling passivation paste as a main agent for chemical treatment, has strong corrosiveness, can generate a large amount of acid mist in the pickling process, has strong irritation and corrosiveness, and operators must wear safety protection tools. Because the stainless steel pool is the restricted space, in order to prevent the acid mist from gathering and causing injury to personnel, the operating personnel adopts alternate system, but can lead to operation interval time to be long, work efficiency reduces.
Taking pickling passivation paste as an example, the main components of the pickling passivation paste are as follows: hf+hno 3; weld surface oxide: fe/Fe 2O3 + NiO. The high acid in the pickling paste plays a role in cleaning dirt, rust, high-temperature oxide and the like on the surface of stainless steel, and the reaction is as follows:
(1) Acid washing process
FeO/Fe2O3+HF+HNO3→Fe3++F-+NOX↑+H2O
Ni/NiO+HF+HNO3→Ni2++F-+NOX↑+H2O
Wherein NOX gas is harmful gas in the pickling passivation process.
(2) Passivation process
The pickling passivation paste can oxidize Cr element in the stainless steel (Cr is preferentially oxidized compared with Fe with the chemical property), and a Cr 2O3 compact protective film is generated on the surface of the stainless steel to isolate the stainless steel from air.
Cr+HF+HNO3→Cr2O3+F-+NOX↑+H2O
(3) Cleaning process
After the pickling passivation paste is brushed for 1 hour, the cleaning water is used for repeatedly flushing and wiping clean, and if the pickling paste is not flushed clean, the stainless steel is continuously oxidized, and the following chemical reaction occurs:
Fe+HF+HNO3→Fe3++F-+NOX↑+H2O
The solution containing iron ions forms a "rust return" when dried.
In order to ensure the safety of stainless steel pickling and passivation operators and improve the working efficiency of pickling and passivation, the invention provides a solution, and the reaction process of oxide on the surface of stainless steel and electrolyte is quickened through electrolytic reaction, so that the deoxidization effect is achieved and the working efficiency can be improved. Because the main components of the electrolyte are weak acids (citric acid and phosphoric acid), compared with strong acids (hydrofluoric acid and nitric acid), the electrolyte reduces the risks of personnel operation health and safety, and can be cleaned by only a small amount of neutralization liquid and B-stage desalted water after use, thereby reducing the wastewater discharge and the pollution discharge cost.
