摘要:
This method for painting a surface (S62) of a component (6) with a pattern includes at least the following steps consisting in applying a first coating product on at least a portion of the surface, automatically applying at least one portion of a mask (12) on a portion (Z62) of the surface, applying a second coating product and on the surface and removing the mask (12). Preferably, the mask (12) is at least partially automatically applied in the form of at least one layer (122, 124, 126) of non-atomized fluid, the layer being obtained by moving (A1) an applicator (16) delivering the non-atomized fluid along the portion (Z62) of the surface (S62) where the mask (12) is to be applied.
摘要:
A paint baking oven (1) is provided which comprises an oven body (10) and a hot air supplier (20) that supplies hot air into the oven body. The paint baking oven bakes a wet coating applied to a vehicle body (B) while conveying the vehicle body. The vehicle body includes a body exterior part and a narrow portion (N1, N2). The oven body (10) is configured to include a spot baking region (122) in which the hot air is blown primarily toward the narrow portion to locally bake a coating film applied to the narrow portion.
摘要:
A coating that contains acid-modified polypropylene and that contains 5 mass% or more of nonvolatile matter is applied to a traveling metal strip in a state in which the surface temperature of the metal strip is 60°C or lower. Next, the coating applied to the metal strip is baked at 80-250°C, and a coating film having a film thickness of 0.3 µm or greater is formed on the traveling metal strip. The proportion of acid-modified polypropylene to resin total mass in the coating film is 40 mass% or higher. The traveling metal strip is then wound after being cooled to a surface temperature of 80°C or lower.
