Description
剥離工程では、図1（A）の陰極板表面に電着した電気銅表面である図1（Ｂ）に温水洗浄をすることにより電解液及び殿物等の汚れを除去している．その後、フレキシングで陰極板から電気銅を剥離し、チゼリングで図1（A）の陰極板と電気銅陰極対面である図1（Ｂ´）との間にチスを入れ、ダウンエンダで陰極板から電気銅を切り離す。その後、電気銅を山積みし、系外へ抜き出している。
（１）パーマネントカソード法により得られた電気銅を剥離機により陰極面から剥離後、山積みした該電着銅をスプレー洗浄し、付着している電解液に伴う不純物を除去する電気銅の品質向上方法。
を提供する。
（１）剥離工程にて図1(B‘)の電気銅陰極板面に付着した電解液の除去ができることから屋外保管の際、雨天時に電気銅に付着した電解液不純物が、周辺等へ流れ出る恐れがなくなる。
ここでは、図2（C）のエッジストリップの中空部である図2（C‘）に入り込んだ電解液は洗浄しきれない。
電気銅を陰極板から剥離する際に、エッジストリップ内部の電解液が陰極板の挟み口部より溢れ出し電気銅陰極面に付着するため、電気銅を汚染する。
剥離機から剥離された電気銅のプレスされたものを山積みし、洗浄装置に配置した。3.9ｔ/山の電気銅を2山用意し、常温にてスプレー洗浄した。
その結果、表１に示すように、電気銅中の全イオウ約2ｐｐｍ、ニッケル分0.4ｐｐｍ低減した。
Claims (1)
- パーマネントカソード法により得られた電着銅を洗浄し、剥離機により、陰極板両面から剥離し、該電気銅の陰極面側が上向きとなるように山積みした後、該電気銅のエッジストリップサイドをスプレー洗浄し、該電気銅の陰極面側の表面に付着した電解液を洗浄し、電解液に伴う汚染物を除去することで、電気銅からイオウ分を２ｐｐｍ以下、ニッケル分を０．４ｐｐｍ以下に低減することを特徴とする電気銅の品質向上方法。
