COATING MATERIAL MIXING DEVICE, AND COATING MATERIAL MIXING METHOD

摘要

[Problem] To provide a coating material mixing device which is capable of adjusting the stirring speed (rotational frequency) of a stirring device in accordance with the weight (capacity) of a coating raw material within a mixing tank, and which can have a relatively simple explosion-proof structure when being used, for example, in a dangerous region in which dangerous objects are handled because unlike conventional stirring devices, the coating material mixing device is not driven by means of an electric motor and so there is no fear of the coating raw material catching fire. To also provide a coating material mixing method. [Solution] A coating material mixing device provided with multiple air pressure adjustment valves for adjusting the air pressure supplied to an air motor in accordance with the weight of a coating raw material within a mixing tank, control valves for switching between the air pressure adjustment valves in accordance with the weight of the coating raw material within the mixing tank, and a control unit for switching between the control valves by selecting a control valve in accordance with the weight of the coating raw material within the mixing tank.
