Equipment for making painted steel plate

Abstract

Abstract PURPOSE:To separately prepare painted steel plates having a plurality of characteristics by single paint, by successively arranging an electron beam or ultraviolet ray irradiation treatment apparatus and a plasma surface modifying apparatus to the post stage of a painting apparatus. CONSTITUTION:Production is performed by usual painted steel plate making equipment up to a top coat painting apparatus and the paint adhered to a steel plate after painting is irradiated using an ultraviolet ray or electron beam irradiation apparatus 8. Whereupon, the constitutional molecules of the synthetic resin contained in the paint are excited to generate polymerization and the paint is cured. At this time, polymerization is generated corresponding to the quality of irradiation beam or ray and the quantity of irradiation energy and the characteristics of paint film changes. When the film after the curing of the paint is subjected to plasma treatment by a plasma surface modifying apparatus 9 using C2F6 gas, only the uppermost surface layer part of the film is further cured. As a result, the scratch resistance, antistaining property and chemical resistance can be imparted to the uppermost surface layer part while the processability of the inner surface of the film is held.
