Abstract

A spray gun comprising a combustion chamber for generating a combustion jet and a barrel which the generated combustion jet is passed through and blown out from. The combustion chamber has an inactive gas supply port for supplying an inactive gas for adjusting the combustion temperature of the combustion jet. The barrel has a supply port for supplying coating particles made of a resin into the combustion jet, and blows out the temperature-adjusted combustion jet together with the coating particles from a blowout port. The spray gun is characterized in that the distance (L) from the supply port to the blowout port is so set that the heating time (t) within the barrel may satisfy the following expressions (1) and (2). Also provided is a control system for this spray gun. In formula (1) herein, α: the coefficient of thermal diffusion of the particles (m2/s), t: the heating time within the barrel (s), r: the radius of the particles (m). In the formula (2) herein, Tav: the average temperature of the combustion jet within the barrel (˚C), Tcp: the critical temperature of particle attachment(˚C)
