摘要： The present invention relates to a method for effectively exfoliating a coating layer from the surface of the conductive substrate of a used electrode for electrolysis comprising an insoluble metal electrode having the coating layer containing electrode substance comprising noble metals and/or their metal oxides on the surface of the used electrode substrate comprising valve metals, such as titanium and tantalum or valve metal alloys, and then to recover the electrode substances and/or electrode substrate for recycling use. The method for exfoliating comprises the steps of treating the insoluble metal electrode surface having the coating layer, in succession, with an alkali treatment process using a caustic alkali aqueous solution, a heating and a baking process and an acid treatment process, the alkali treatment process being conducted by applying an alkali treatment solution prepared by adding thickener to the caustic alkali aqueous solution.

摘要： Prior to immersion of an object to be treated in a degreasing liquid, an aqueous solution 20 having a pH of 5.5 to 10. 0 is put into a sac-shaped portion of a vehicle body 2. Even when the vehicle body 2 is passed through the degreasing liquid, the aqueous solution 20 is not replaced with the degreasing liquid, and alkaline solid substances do not remain in the hemmed portion 2a. This prevents the water in the sac-shaped portion from having the high alkalinity even when water comes into the hemmed portion 2a later. The degreasing method can prevent the decrease in corrosion resistance of the joint portion of the object to be treated.
