摘要： A steel sheet for a large structure according to the present invention is a steel sheet for a large structure having a film of a primary rust-proofing paint containing a silicate type binder and zinc powder as a rust-proofing pigment formed on the surface thereof, a mean dry film thickness of the film is 3 to 10 mu m, and a variance index of the film thickness is not greater than 0.18. An application method of a primary rust-proofing paint according to the present invention can form a thin homogeneous film allowing high speed fillet welding at a rate exceeding 100 cm/min on the surface of a steel sheet for a large structure by causing an inorganic zinc primary rust-proofing paint to exhibit its excellent rust-proofing property to maximum. A coated steel sheet for a large structure according to the present invention is produced by forming a powder paint film on the thin homogeneous film of the primary rust-proofing paint formed on the surface on the steel sheet for a large structure. This coated steel sheet can prevent the occurrence of air bubbles inside the powder paint film at the time of baking of the powder paint film, the occurrence of pin-holes on the surface of the powder paint film and cohesive failure of the inorganic zinc primary rust-proofing paint in a coating layer at the time of curing of the powder paint film, that have been the problems in the past, by fully displaying excellent rust-proofing property of the inorganic zinc primary rust-proofing paint. Therefore, the coated steel sheet is excellent in rust-proofness and productivity.

摘要： PURPOSE: To form a homogenous coating film by repeatedly performing a process applying a primary rust preventing coating material to the surface of a steel panel unidirectionally or reciprocally by using a coating line wherein a plurality of spray tips are arranged along the advance direction of the steel panel to be coated for a large-sized structure and the direction crossing the steel panel at a right angle so as to leave an interval between the spray tips. CONSTITUTION: A large-sized structure such as a ship or a bridge is constructed using a steel panel preliminarily subjected to rust preventing treatment and coated with a primary rust preventing coating material. When the primary rust preventing coating material is applied to the steel panel 1 for the large-sized structure, a coating line wherein a plurality of spray tips are arranged along the width direction of the steel panel 1 so as to leave an interval between the spray tips is used. In this case, the interval between the spray tips in the width direction of the steel panel is set to 1/n (n; integer of 2 or more) the width of a spray pattern. After the spray coating with the primary rust preventing coating material is applied to the steel panel 1 while the steel panel is unidirectionally advanced, a process wherein the spray tips are moved in a reverse direction in synchronous relation to the advance speed of the steel panel is repeated to form homogeous film thickness wherein average dry film thickness is 10-50μm and the irregularity index of film thickness is 0.18 or less.

摘要： PURPOSE:To provide a zinc shop coat primer for use in high-speed welding, which has excellent weldability, workability, rustproofness, etc., by mixing a soln. of colloidal silica in an org. solvent with polyvinyl butyral and then mixing the mixture with an extender pigment, a suspending agent and zinc powder. CONSTITUTION:A soln. of colloidal silica in an org. solvent is mixed with polyvinyl butyral in a weight ratio of pref. 100:0-35 on a solid basis. The mixture is mixed with a conventional extender pigment, a conventional suspending agent and zinc powder in such an amount that the amount of zinc powder accounts for 50-70% of the resulting dry coating film, thus obtaining the desired zinc shop coat primer for use in high-speed welding. The org. solvent is evaporated from the coating film of the org. solvent type colloidal silica, whereby the dry film is converted into a completely inorg. matter which contains no hydrogen source. Since polyvinyl butyral has a low heat decomposition point and is heat-decomposed during welding and converted into a material which contains less hydrogen sources, the resulting zinc shop coat primer has excellent weldability.
