Abstract
|
|
|
The dyeability of chromate-conversion-treated coating on the zinc electroplated was discussed according to the dyeing method of anod-oxide-coating in aluminum.
And the effects of dyeing were investigated by measuring the absorbed amount of dyestiff by means of spectrophotometry.
The results are as follows:
1. The absorbed amount of dyestuffs was increased when the concentration of dyeing solution was increased and the temperature of it rose higher.
2. The absorbed was amount of dyestuffs tended to be decreased in the case of over 10 g/l and 50℃.
3. The absorbed amount of dyestuffs was increased in accordance with the length period.
4. The adjustment of pH was very significant, the best result was ganinde while it was approximate to pH10. And while it was pH(6 and pH)11, chromate film was corrded.
