| 摘要 |
The present invention effectively prevents, in an electrodeposition system, deterioration of finished coating quality caused by a paint-containing aqueous solution flowing out of steel-plate fitting portions when performing drying treatment, while avoiding secondary problems such as an increase in the size of the system, increases in initial costs and running costs, a loss of reliability, and so forth. A washing zone that follows an electrodeposition zone in which a coating film is formed on a surface of an object to be coated by immersing the object to be coated in an electrodeposition paint solution is provided with: a hot washing bath in which the object to be coated is washed by being soaked in a high-temperature washing liquid in the bath; and a spray washer that, following washing in this hot washing bath, sprays a high-temperature washing liquid onto steel-plate fitting portions in the object to be coated. |
