を劣化させてしまうといった不都合が生じる。In the system in which the heat of the heater is applied to the surface of the work as radiant heat and dried as described above, even if the temperature of the heater itself is strictly controlled, or the work is heated. Even if the distance between the work and the heater is strictly controlled, it is impossible to keep the surface temperature of the work in such a narrow range due to changes in the environment, etc. If the temperature is lower than this range, the evaporation rate of the solvent decreases, the coating film surface is cured first, and the coating material evaporates after curing, which causes the problem of pinholes on the surface of the coating film. If the temperature is higher than this temperature range, excessive solvent evaporation, that is, an overbaking, may occur and the coated surface may be deteriorated.
