Claims (5)
- 洗浄槽内に、フッ素系溶剤、塩素系溶剤、又はフッ素系溶剤と塩素系溶剤との混合溶剤から成るとともに水より比重が大きい非水系の洗浄溶剤と、水とを収納することにより、洗浄溶剤の層の上面に水の層を被覆配置し、下層側に位置する洗浄溶剤にて被洗浄物に付着した油分を除去する脱脂洗浄を行った後、この脱脂洗浄によって被洗浄物に付着した洗浄溶剤を、水にて物理的に除去する溶剤除去洗浄を行うことを特徴とする被洗浄物の脱脂及び溶剤除去洗浄方法。
- 非水系の洗浄溶剤は、加水分解が困難な洗浄溶剤であることを特徴とする請求項1の被洗浄物の脱脂及び溶剤除去洗浄方法。
- 上記溶剤除去洗浄は、脱脂洗浄後の被洗浄物を洗浄槽内の水の層に浸漬して行うか、又は脱脂洗浄後の被洗浄物に水を噴射することにより行うことを特徴とする請求項1の被洗浄物の脱脂及び溶剤除去洗浄方法。
- 上記脱脂洗浄の前に、洗浄槽内の水に被洗浄物を接触させ、この被洗浄物に付着した油分を上記水にて物理的且つ大まかに除去する予備洗浄を行うことを特徴とする請求項1、または2の被洗浄物の脱脂及び溶剤除去洗浄方法。
- 上記溶剤除去洗浄の後、被洗浄物を温風、熱風、エアブロー、または水切りにて乾燥することを特徴とする請求項1、2、または3の被洗浄物の脱脂及び溶剤除去洗浄方法。
