Abstract
Description
まず、ヨウ素滴定により処理液(過硫酸塩の溶液S)中に含まれる全酸化剤濃度を測定する。このヨウ素滴定とは、過硫酸塩の溶液Sにヨウ化カリウム(KI)を加えてヨウ素(I2)を遊離させ、このI2をチオ硫酸ナトリウム標準溶液で滴定してI2の量を求め、そのI2の量から酸化剤濃度を求めるものである。次に、過硫酸塩の溶液Sの過酸化水素濃度のみを過マンガン酸カリウム滴定により求め、ヨウ素滴定値から過マンガン酸カリウム滴定値を差し引くことにより過硫酸濃度を算出した。
過硫酸塩の溶液Sにより親水化処理されたポリプロピレン樹脂板7に対し、下記表1に示す流れでめっき処理を施し、密着性試験用サンプルとした。
図1に示す装置を用いて、ポリプロピレン樹脂板7の表面処理を行った。処理槽2の仕様及び条件は次の通りである。
処理槽2の容積:40L
ポリプロピレン樹脂板7の大きさ:500mm×500mm×厚さ5mm
<過硫酸塩の溶液Sの性状と表面処理条件>
硫酸濃度:92wt%
過硫酸濃度:10g/L
処理温度:120℃
処理時間:60分
表面処理条件を表2に示すように種々設定を変更したこと以外は実施例1と同様にしてクロムめっきを施し、めっきの密着性を評価した。結果を親水化処理条件とともに表2にあわせて示す。
過硫酸塩溶液の代わりに、硫酸濃度92wt%の硫酸溶液を用いた以外は実施例1と同様にしてクロムめっきを施し、めっきの密着性を評価した。結果を処理条件とともに表2にあわせて示す。
