For example, HFE is an abbreviation for hydrofluoroether and is a fluorine-based inert liquid represented by the chemical formula C 4 F 9 OCH 3 or C 4 F 9 OC 2 H 5 and has a low surface tension and low viscosity. It has excellent wettability with solid materials, has almost no compatibility with water, is thermally and chemically stable, has an ozone destruction coefficient of 0, and is practically harmless. Also, HF

These fluorinated inert liquids have a specific gravity greater than that of water, but hydrocarbon-based liquids used as drainage drying solvents having a specific gravity smaller than water specifically have a specific gravity of 0.7 to 0. A cleaning solution containing a single component of about 0.8 purified normal paraffin as a main component is suitable. These are solvents having a high flash point, an excellent drying property, a property of being easily regenerated by distillation, and a property of a liquid composition that is hard to change, and can be used in the same manner as the above-mentioned hydrofluoroether.

Next, the second requirement is that an appropriate amount of a surfactant is added to the draining and drying solvent to obtain a cleaning solution. In this case, it is appropriate to contain 1% by weight or less of an anionic surfactant. Further, it is preferable that such a cleaning liquid is heated to increase the cleaning efficiency. H
When FE is applied, it is particularly preferable to increase the activity of the cleaning solution by heating to the temperature at or near the boiling point.

In the present invention, since the cleaning liquid contains the surfactant, when the work is taken out from the cleaning liquid, the liquid flows smoothly and the liquid drops hardly remain. As well as playing, the effect of preventing rusting of the work after the cleaning process is obtained. Therefore, a remarkable advantage is obtained in that the rust prevention treatment step which was required in the case of the conventional washing water is not required.

The amount of the anionic surfactant added is:
Even at about 0.25%, a considerable effect can be obtained, but even if it exceeds 1%, no significant improvement in the draining effect is observed. The rust-preventing effect of this washing treatment was compared with the case of treatment with a commercially available water-based rust-preventive agent. In the case of a commercial product, rusting was observed after 3 days of standing, but in the case of the present invention, rusting was observed. Rust is left 2
After a week, a sufficient rust prevention effect was recognized. Since the surfactant adheres to the work and is taken out, it is preferable to replenish the surfactant sequentially to maintain its concentration.

Further, a third requirement is that, when cleaning the work, ultrasonic waves are irradiated by the ultrasonic vibrator 23 while being immersed in the cleaning liquid. This ultrasonic irradiation is an important operation, and when only immersion treatment is performed without using ultrasonic waves, it is recognized that salts such as sodium nitrate, which is an electrolyte component, remain as crystals in the work after drying. Can be This phenomenon is particularly noticeable in uneven portions such as processing scratches on the work surface, and causes poor cleaning.

What is necessary is just to prepare according to the washing | cleaning liquid 21 of the washing tank 2. Note that this rinsing cleaning is not necessarily essential, and may be arranged as necessary. When rinsing cleaning needs to be performed more completely, such rinsing washing tanks may be arranged in two to three stages. .

In the method of removing an electrolytic solution according to the present invention, in the cleaning step after the electrolytic deburring treatment, a draining dry solvent composed of a fluorine-based inert liquid or a hydrocarbon-based liquid is used as the cleaning liquid, and And irradiate ultrasonic waves at the same time to apply ultrasonic vibrations to the surface of the work, so that the electrolyte adhering to the work can be efficiently peeled off. Until then, the brought-in electrolyte can be reliably removed.

Since the boiling point of the cleaning liquid itself used in this method is very low, the cleaning liquid adhering to the work after the cleaning treatment is quickly volatilized and dried.
If the cleaning liquid is heated to near the boiling point and a cooling zone 22 is provided in a space above the cleaning liquid, only the cleaning work is temporarily retained in the cooling zone 22 when the cleaned work is taken out.
It can be dried very easily. Thus, the conventionally used heating and drying step becomes completely unnecessary, and the work can be transferred to the next step immediately after the cleaning treatment.

Next, another embodiment of the present invention will be described with reference to FIG. In FIG. 1, the electrolytic treatment tank 1
The electrolytic solution recovery tank 4 disposed between the cleaning liquid and the cleaning tanks 2 and 3 is for separating and recovering the electrolytic solution transferred to the cleaning liquid from the cleaning liquid. Taking the case where a fluorine-based inert liquid having a large specific gravity is used as the cleaning liquid as an example, the cleaning liquid 21 of the first cleaning tank 2 is led out to the electrolyte recovery tank 4 from above.
When the cleaning liquid stored in the electrolyte recovery tank 4 is allowed to stand, it is separated into a lower liquid phase 41 made of a fluorine-based inert liquid having a large specific gravity and an upper liquid phase 42 made of an electrolyte having a relatively small specific gravity. Will be.

However, depending on the degree of contamination of the impurities, the electrolyte may be returned after performing appropriate purification treatment as needed. Further, the lower liquid phase 41 can be set to be returned to the first cleaning tank 2 instead of the second cleaning tank 3.

When a draining dry solvent composed of a hydrocarbon liquid having a low specific gravity is used in place of the fluorine-based inert liquid as the cleaning liquid, an upper liquid phase 42 composed of a hydrocarbon liquid having a low specific gravity is used. Thus, the lower liquid phase 41 composed of the electrolyte having a relatively large specific gravity is separated. Therefore, contrary to the case of the fluorine-based inert liquid, the upper liquid phase 42 is returned to the first or second cleaning tank 2 or 3, and the lower liquid phase 41 is returned to the electrolytic processing tank 1. do it.
