Abstract
PURPOSE:To pretreat a copper wire rod perfectly and to make plating treatment in succession to this uniform by heating said wire rod then immersing the rod in an aq. soln. contg. a reducing agent, and subjecting this to an acid treatment followed by a plating treatment. CONSTITUTION:A wire rod such as mild copper wire or hard copper wire is passed through a pipe 12 in a heating furnace 11 which is heated to about 400- 700 deg.C. This rod 17 is passed through a water tank 14 where the leading end 13 of the pipe 12 is located in a soln. contg. a reducing agent such as alcohol, so that the surface of the rod 17 is cleaned by reduction. This is passed through a pretreating tank 15, where it is applied with an acid treatment with aq. mixed solns. of zinc chloride and hydrochloric acid, after which it is plated in a plating tank 16 and is coiled as a plated wire rod 18. The pretreatment and the plating treatment are accomplished perfectly by such method. This plated copper wire is effective for applications such as lead wires of resistance capacitors and electronic wires.
