Oxidation resistant protection method for ears of pole plate of accumulator

Abstract

A procedure for producing pole plate includes steps: first, preparing metal sheet grating; manufacturing raw pole plates from sheet gratings; being installed into accumulator, raw pole plates are as chemical energy source to be activated; painting a layer of protective agent on plate ear of sheet grating after sheet grating being heated to 15-100 within 24 hours after sheet grating being produced; temperature of the protective agent is controlled at 180-80 deg.C. Boiling point of the protective agent is higher than temperature in each step of producing raw pole plates, and is lower than temperature when flow weld or burnt together are carried out between plate ear and bus bar. The said protective agent is prepared by using vacuum residue of microcrystalline wax as raw material through following steps: propane deasphalting, furfural refining, acetone-benzene dewaxing and deoiling, additional treatment of clay. Features are: high production rate, and preventing lead pollution.

Description

technical field [0001] The invention relates to a method for protecting the plate ear of a storage battery from oxidation and contamination during production. Background technique [0002] In the lead-acid battery production industry, the busbar is welded on the plate ear. The function of the bus bar is to gather the current generated by the chemical reaction on the plate and provide it to external electrical appliances, or to obtain current from the outside and distribute it to the plate to charge the battery. The bus bar acts as an intermediate medium for collecting current and is in a very important link. [0003] If the welding between the bus bar and the plate ear is not good, it will seriously affect the performance of the battery. What's more serious is that if there is false welding between the bus bar and the plate lug, resulting in an increase in resistance, it may cause the explosion of the hydrogen and oxygen mixture produced by hydrolysis accumulated during th...

AI Technical Summary

Problems solved by technology

The welding of the plate lug and the bus bar is not good, mostly because the oxide layer and dirt on the surface of the plate lug are not cleaned, so the oxide layer and dirt on the surface of the plate lug must be cleaned

[0005] In the current battery production, the welding of the busbar is usually cast welding or manual welding. It takes a lot of manpower and material resources to remove the oxide layer and dirt on the surface of the plate lug before welding, which increases the production process and removes During the process, a large amount of toxic lead particles and dust will be produced, which will pollute the environment and bring great harm to the health of production personnel.
