Example Embodiment
[0017] Example 1
[0018] Combine figure 1 with figure 2 As shown, a grid manufacturing process of the present invention is to use carbon, aluminum or a conductive alloy to make a grid-shaped grid 1, and spray lead or lead alloy 2 with a thickness of 0.1mm-2mm on the grid after forming 1. For the surface layer of 1, the lead layer on the surface is adhered to the grid by strong extrusion, or the surface is strongly squeezed on the surface layer of the grid with a thin lead plate of 0.1mm-0.8mm thick, resulting in the surface layer The lead density is increased by more than 5 times.
[0019] Wherein, the main component of the carbon can be activated carbon, silicon carbon or carbon alloy material, and copper powder, silver powder, aluminum powder, graphite, superconducting carbon, graphite emulsion or conductive carbon black can be added to the carbon alloy material; The alloy is copper alloy, aluminum alloy or zinc alloy; lead can be pure lead or lead alloy, and lead alloy can be...
