酸鉛鉛被膜形成させるもので。Here, when performing the K base treatment on the steel plate (2), a so-called chemical reaction method has conventionally been used. This chemical reaction method involves pouring a zinc phosphate-based chemical dissolved in water onto the surface of a steel plate, causing a chemical reaction with the surface of the steel plate to form a lead phosphate coating on the surface of the steel plate.
これによると被膜の形成に時間（通常３分程度の反応時

いる。After that, the steel plate (2) is transferred to the coating booth (4!l) of the coating device α9 that fires the process αG.In the coating booth 09, polyester powder paint colored in a predetermined color is transported from the tank mark. The powder coating is passed through the pipe 6〃, passed through the pulp (c) by the pump 62, and is blown out from the nozzle 54), and the powder coating is applied to the upper surface of the steel plate (2) to a predetermined thickness (35μ to 40μ). Electrostatic painting is carried out.The air inside the booth μs is constantly exhausted by a blower engine through a filter (49), which creates a slight negative pressure inside the booth (49), which prevents paint from leaking.

する。The steel plate (2) coated in the booth (4ω) is then transferred to the baking dryer 6η that performs the process 0υ, where it is heated by a plurality of far-infrared heaters, and the coated powder is heated. The paint melts, dries, and hardens.Then the steel plate (2)
is transferred to cooling device (2) which executes step α2. Outside air is circulated inside the cooling device by a blower, which lowers the temperature of the steel plate (2) and finishes the painting.

Furthermore, since the powder coating is applied and cured by heating, it is easy to ensure the thickness of the coating film, and it is possible to achieve a so-called durable coating. In particular, in the present invention, the base treatment agent uses an inorganic compound as a binder to give it an appropriate viscosity and is applied to the steel plate using a roll coater, so the process can be completed in a shorter time than when the base treatment is performed by a required chemical reaction. be able to. Therefore, it is possible to reduce the amount of painting equipment and time at the equipment manufacturing site.
