Spacing between sub-electrode controls at 1mm-10mm.
As a modification of the present invention, in step s 2, during carrying out plasma discharge treatment,
Described grid translational speed in described treatment box is 0.5 m/min-8 ms/min.
As a modification of the present invention, described grid is the grid for spirally wound lead acid battery,
And described grid is to draw in the net plate with the. g., lead tape using casting and rolling process to obtain for prepared by grid base material
Grid or punching press grid are drawn in the net in grid, punching.
Use technique scheme, the method have the advantages that
By using plasma discharge treatment to form nitrogen oxidation film on the surface of grid, existing not changing
In the case of production technology, effectively raise the adhesion of the electrode active materials such as lead plaster and grid,
Grid can be improved simple with the adhesion of lead plaster and technique, the mechanicalness of grid can also be improved simultaneously
Energy and decay resistance.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described further.
The lead acid accumulator plate grid surface treatment method that the present embodiment provides, comprises the following steps:
S1, being carried out grid, remove the surface smut of grid, in the present embodiment, grid is
For the grid of spirally wound lead acid battery, and grid is the. g., lead tape using casting and rolling process to obtain
Grid or punching press grid are drawn in the net in draw in the net grid, the punching prepared for grid base material, and this kind of grid surface is more
Smooth, poor lubricity and corrosion resistance are high, it is difficult to be directly combined with the electrode active material such as lead plaster.
Preferably, in the present embodiment use ultrasound wave grid is carried out, ultrasonic waves for cleaning time
Between be 0.5 minute-5 minutes, the concrete time can be determined according to practical situation, as long as can
Guarantee that grid can be cleaned.The cleanout fluid that ultrasonic waves for cleaning is used can be clear water or
