寸たは酢酸ニッケル系の封孔剤により行なわれている。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning method σzuki Yuyoshi after sealing treatment of a single anode oxide film applied to the surface of an aluminum Uno. The surface of the oxide film (including dyeing, natural coloring, and electronic coloring) becomes a porous layer, so it is necessary to seal the pores and improve corrosion resistance and physical properties. It is well known that hole processing is performed. Generally, there are two methods for sealing, one using pressurized steam and the other using boiling water, and the present invention particularly relates to the latter. When sealing the anodic oxide film with boiling water (including temporary sealing), generally the treatment PJA degree is 80 to 100.
The process is carried out using ion exchange water or a nickel acetate sealant under conditions of a treatment time of 10 to 40 minutes at 1°C.

・It is pulled out and moved to the next process, but at that time, due to the high temperature in the tank, it dries quickly 2, so the eluted aluminum oxide UNO and the components of the sealant are on the surface of the anodic oxide film. If stains, unevenness, or peeling occur when you apply a piece of paper to the fabric, wiping it with cloth in the subsequent process is a good idea. Furthermore, in cases where the 7Ij deviation is significant, such as -S, it may be impossible to remove it, resulting in product defects.

The object to be treated is cooled to ~50°C and then sealed using a solenoid or the like before drying. Things never dry out. It was used for the hole sealing process. ζ, which is the same as the liquid, is drawn from the tank, 1 and 1.
There is no reaction to the treatment liquid applied to the surface of the object. It can remove aluminum oxide and other substances. Next, after pouring water 6,
By immersing it in carboxylic acid water (water solution), it is cleaned to a uniform surface and a homogeneous surface is obtained, and the surface appearance is improved from the original. 1. Therefore, the surface of the 1 hot water printing oxide film that has been washed by the present invention will be clean and free from defects such as stains and uneven dimensions/ζ.

Increasing the bath temperature can speed up the cleaning process and shorten the soaking time, but raising the temperature above 80°C can have a negative impact on the skin. The temperature J7 and the time four times are also determined by taking into account the consistency of the stains and stains on the film 1, as well as the acid 411.Furthermore, as the determinant of the brown color of these treatments, The quality of the oxide film, that is, the quality of the oxide film, the Jji of the electrolytic bath of the oxide film, the film thickness, the chemical forming bath temperature, etc. are different, and these four times are combined for treatment. The conditions are determined. Note that if the v/* time is set to 20 minutes or more, the anodic oxide film will be dissolved.
