Example Embodiment

[0075] Example one:

[0076] Such as figure 1 As shown, the preparation of treatment solution 11: Add quantitative pure water in the treatment solution pool, and add Na in the ratio of 1% to 2% 2 SO 4 , Stir well to get Na 2 SO 4 Solution.

[0077] Discharge acid 12: Open the acid discharge valve at the bottom of the chemical conversion tank after the chemical conversion is completed, drain the acid in the chemical conversion tank into the electrolyte density adjustment tank, and use a small amount of pure water to wash away the remaining acid at the bottom of the chemical conversion tank .

[0078] Add treatment solution 13: Close the acid discharge valve, open the treatment solution valve, and add the prepared 1% to 2% Na in the chemical conversion tank 2 SO 4 Solution until the positive and negative plates are completely submerged.

[0079] Discharge 14: Put the chemical transformation charging power supply into the discharge state, and discharge the chemical transformation el...

Example Embodiment

[0083] Embodiment two:

[0084] Such as Figure 4 As shown, the preparation of treatment solution 11: add quantitative pure water to the treatment solution pool, and add Na in the ratio of 1% to 2% 2 SO 4 , Stir well to get Na 2 SO 4 Solution.

[0085] Fabrication of processing tank 21: The non-welded chemical conversion tank of the same size as the chemical conversion is used as the processing tank, and the non-welded chemical conversion frame is placed in the tank. The lead alloy busbar is inserted at the corresponding position of the lower part of the chemical conversion frame, and the lead alloy grid is used as the positive electrode Plate, insert it into the corresponding tooth slot, and weld it firmly to the forming bus bar to form a positive plate group.

[0086] Adding treatment solution 13: Add the prepared 1% to 2% Na in the treatment tank 2 SO 4 Solution, the amount added should be able to ensure that the negative plate is completely submerged when the negative plate is...

Abstract

The invention discloses a discharge washing-free treatment process for lead-acid accumulator formation plates, which comprises the steps of formulating treatment fluid, exhausting acid liquor, adding treatment fluid, discharging, treating a negative plate, treating a positive plate and cyclically formulating treatment fluid and the like in turn. The invention further discloses a reverse charging washing-free treatment process for lead-acid accumulator formation plates, which comprises the steps of formulating treatment fluid, making a treatment tank, adding treatment fluid, inserting the negative plate, inversely charging, treating the negative plate, cyclically formulating treatment fluid and washing the positive plate and the like. The utility model treats the formation plates with the discharge or reverse charging processes, which can reach the required treatment effects without washing, and has extremely low water consumption in the process of treatment, can realize the cyclical utilization, reaches zero emission effect, and greatly relieves the pressure of environment protection. The plates can generate PbSO4 to attach on the surface of plate holes in the process of discharge, which can play the role of protection, and prevents the negative plate from further being oxidized, thereby increasing the dry-charged property of plates.

Description

technical field [0001] The invention relates to a treatment method for forming a polar plate of a lead-acid battery, in particular to a washing-free treatment method for forming a polar plate of a lead-acid battery. technical background [0002] In the production of batteries, formation is a very joint link. In this process, the components (PbO, PbSO) of the solidified plate (green plate) will be completed. 4 , PbO·PbSO 4 , 3PbO·PbSO 4 ·H 2 O, 4PbO PbSO 4 ·H 2 O) In the dilute sulfuric acid solution, feed the specified amount of electricity to make it into the chemical and electrochemical transformation of the positive and negative working active materials, that is, the electrochemical oxidation reaction of the lead paste on the positive plate produces PbO 2 At the same time, the electrochemical reduction reaction occurs on the negative plate to generate porous sponge-like Pb. The components of the plates are externally formed and internally formed. Externally, the pla...
