Embodiment 1
[0016] One embodiment of the present invention can be made of lead 2 wrapped around the carbon-based material 1 and then extruded, such as figure 1 The lead-coated carbon composite shown in 3.
[0017] Among them, the carbon-based material 1 can be powdered or rod-shaped as the matrix, and its main component can be activated carbon or carbon alloy material, and can also add conductive agent and binder, for example, can add copper powder, silver powder, aluminum powder, Graphite, superconducting carbon, graphite milk or conductive carbon black can be used as a conductive agent, and clay or resin can be added as a binder; lead 2 can be pure lead or alloy lead, and alloy lead can be lead-antimony alloy, lead-calcium alloy, lead-antimony alloy Arsenic tin alloy or lead calcium tin aluminum alloy.
[0018] combine figure 2 As shown, the thin lead skin can also be coated on the carbon powder or the carbon rod, or a certain thickness of lead can be cast on the carbon rod, and then...
