Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The main solution of the embodiment of the invention is as follows: acquiring the field information of a stainless steel welding line and the surface to be processed; adjusting the gear of 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 processed, and switching on an operation power supply of the processing equipment so as to enable the operation brush head and the electrode on the stainless steel welding seam and the surface to be processed to be changed alternately through an inverter in the processing equipment; and brushing the pre-prepared electrolyte on the stainless steel welding line and the surface to be treated through the operation brush head so as to remove oxides on the stainless steel welding line and the surface to be treated and generate a passive film. The electrolyte is coated on the stainless steel welding seam and the surface through the operation brush head of the treatment equipment, the electrodes between the treatment equipment and the stainless steel welding seam and between the treatment equipment and the surface are alternately changed under the control of the inverter, the electrolyte decomposes oxides on the stainless steel welding seam and the surface, the deoxidation effect is achieved, meanwhile, the electrochemical reaction quickly generates a passivation film, and the treatment efficiency of the stainless steel welding seam and the surface is improved.
The traditional pickling passivation process mainly adopts pickling passivation solution or pickling passivation paste and other strong-oxidability nitric acid as a main agent for chemical treatment, has strong corrosivity, can generate a large amount of acid mist in the pickling process, has strong irritation and corrosivity, and is necessary for operators to wear safety protection tools. Because the stainless steel water tank is a limited space, in order to prevent the acid mist from gathering and causing harm to personnel, the operating personnel adopt the alternate system, but the operating interval time is long, and the working efficiency is reduced.
Taking the acid-washing passivation paste as an example, the acid-washing passivation paste comprises the following main components: HF + HNO3(ii) a Weld surface oxides: Fe/Fe2O3+ NiO. The high strong acid in the pickling paste plays a role in cleaning dirt, floating rust, high-temperature oxide and the like on the surface of the stainless steel, and the reaction is as follows:
(1) acid pickling process
FeO/Fe2O3+HF+HNO3→Fe3++F-+NOX↑+H2O
Ni/NiO+HF+HNO3→Ni2++F-+NOX↑+H2O
Wherein the NOX gas is a harmful gas in the pickling and passivation process.
(2) Passivation process
The pickling passivation paste can oxidize Cr element in the stainless steel (Cr is more active than Fe and can be preferentially oxidized) to generate Cr on the surface of the stainless steel2O3The dense protective film isolates 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 pickling passivation paste is repeatedly washed and wiped clean by using clear water, if the pickling paste is not washed clean, the stainless steel is continuously oxidized, and the following chemical reactions occur:
Fe+HF+HNO3→Fe3++F-+NOX↑+H2O
the solution containing ferric ions forms "back-rusting" when it dries.
In order to guarantee the safety of stainless steel pickling and passivating operators and improve the working efficiency of pickling and passivating, the invention provides a solution for accelerating the reaction process of the oxide on the surface of the stainless steel and the electrolyte through electrolytic reaction, thereby playing a role in deoxidation and improving the working efficiency. 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 health and safety risks of personnel operation are reduced, and only a small amount of neutralizing liquid and B-grade demineralized water can be used for cleaning after the electrolyte is used, so that the wastewater discharge is reduced, and the pollution discharge cost is reduced.
