Controls coating thickness. However, when the spray gun is moved, good results cannot be obtained by controlling the coating range by the viscosity of the paint, and unnecessary overcoating or film breakage occurs.

Based on the relationship between the ratio, the spray gun height (distance to the surface to be sprayed, and the coating area), the height of the spray gun is controlled according to the specific gravity of the paint used to obtain a predetermined coating area. This is a method of painting steel plates.

た。(Function) The present inventors have stabilized the primary anti-rust coating of steel plates, etc.
As a result of experiments and studies, we have found that, in order to ensure smooth operation, the temperature of the paint can be adjusted by making the runway gutter of the spray gun to which the spray gun is attached movable, instead of making the main body of the spray gun movable up and down. It was discovered that even if coating properties change due to changes in brand, etc., coating can be done stably and smoothly.
しかしながら、スプレイガンの位置が変化する
と、塗装範囲（塗布面積）は単に塗料の粘度をも
とにしては制御が不能で、これの制御因子が塗料
の比重であることを知見した。この関係を第１図
に示す。 However, when the position of the spray gun changes, the coating range (applied area) cannot be controlled simply based on the viscosity of the paint, and it has been found that the controlling factor is the specific gravity of the paint. This relationship is shown in FIG.
塗装範囲（塗布面積）は、スプレイガンが一定
している時は、塗料の粘度が同じであつても、そ
の比重が異なると差を生じ、理由は定かでない
が、粘度２０の塗料より粘度１０の塗料の方が、
その変化の巾は大きい。 When the spray gun is fixed, the coating range (coated area) will differ if the specific gravity of the paint is different even if the viscosity is the same.For reasons that are not clear, a paint with a viscosity of 10% is less than a paint with a viscosity of 20%. The paint of
The range of change is large.
