COATING-RECOATING METHOD OF STEEL MEMBER
PROBLEM TO BE SOLVED: To recoat coating from above its rust-preventive layer, and to recoat the coating by separately peeling the rust-preventive layer and an outer coating layer, by leaving the rust-preventive layer, when recoating the coating.SOLUTION: A first coating-recoating method of the present invention is a method for recoating coating by coating new paint on a remaining existing rust-preventive layer by peeling an outer coating layer in a sheet state by leaving the rust-preventive layer by softening a coating film by its heat by heating a steel member surface by induction heating. A second coating-recoating method of the present invention is a method for recoating the coating by coating new paint on the outside of its newly formed rust-preventive layer by forming the rust-preventive layer by coating a rust-preventive material on an exposed steel member by cutting and removing the remaining rust-preventive layer by a mechanical apparatus by peeling the outer coating layer in the sheet state by leaving the rust-preventive layer by softening the coating film by its heat by heating the steel member surface by the induction heating.SELECTED DRAWING: Figure 1
【課題】 塗装の塗り替えに際して、錆止め層を残し、その錆止め層の上から塗装を塗り替えられるようにすること、及び錆止め層と外塗り層を別々に剥離して塗装の塗り替えを行えるようにすること。【解決手段】 本発明の第一の塗装塗り替え工法は、誘導加熱で鋼部材表面を加熱してその熱で塗膜を軟化させ、錆止め層を残して外塗り層をシート状態で剥離し、残った既存の錆止め層の上に新たな塗料を塗って塗装の塗り替えを行う工法である。本発明の第二の塗装塗り替え工法は、誘導加熱で鋼部材表面を加熱してその熱で塗膜を軟化させ、錆止め層を残して外塗り層をシート状態で剥離し、残った錆止め層を機械器具で切削して除去し、露出した鋼部材に防錆材料を塗布して錆止め層を形成し、その新たに形成された錆止め層の外側に新たな塗料を塗って塗装の塗り替えを行う工法である。【選択図】図１
