傷は除去される。同時に白化部が形成される。First, in the present invention, a flaw is polished and ground with a sandpaper or a grinding drill. Such a process can be performed in the same manner as the conventional repair method. By the polishing / grinding process, cuts and scratches are removed as shown in FIG. At the same time, a whitened portion is formed.

処理を採用することが出来る。Next, in the present invention, before the hot air heating process described later, the internal water content of the above-mentioned polishing / grinding processing section is reduced by 200%.
A drying process is performed to reduce the concentration to less than ppm. The feature of the present invention resides in this point. By the drying treatment, the generation of bubbles due to the evaporation of water during the hot air heating treatment is eliminated, and therefore, the high-temperature hot air heating necessary for sufficiently clearing the whitened portion is performed. Processing can be employed.

Such a treatment can be performed using a hot dryer or the like in the same manner as the conventional repair method. However, in the present invention, unlike the conventional repair method,
The generation of air bubbles inside the resin does not matter at all, and the hot air temperature can be sufficiently increased. Although the specific hot air temperature is not particularly limited, it is usually 200 to 350 ° C., preferably 250
~ 300 ° C. As shown in FIG. 1 (d), the fine rough surface formed in the polishing / grinding section is smoothed and the whitened section is made transparent by the hot air heating treatment in the polishing / grinding section.

The scratches on the surface of the container were polished using the respective sandpapers of No. 0 in order. Next, the container was left for 3 hours in a hot air dryer set at a temperature of 120 ° C. to be dried. The moisture in the container material before drying was about 800 ppm, and the moisture after drying was about 100 ppm. Then, the polishing section was taken out of the dryer and immediately heated by a hot drier at an outlet hot air temperature of 260 ° C. for 30 seconds. By the hot air heating treatment, the fine rough surface formed in the polishing treatment part was smoothed, and the whitened part was made transparent. Of course, no bubbles were generated inside the resin. Therefore, the repair marks were not noticeable.
