摘要:
To obtain an accurate concentration of nonvolatile contents promptly and easily, an electrodeposition paint of which pH, temperature, and organic solvent concentration are in specified ranges is irradiated with ultrasonic waves, and its damping factor is measured, and on a basis of the result from the measurement, the concentration of nonvolatile contents in the electrodeposition paint is determined.

A single chamber type coating and baking apparatus which includes a chamber having one opening through the ceiling and two openings through the floor. A means for discharging the air within the chamber to the outside is connected to one of the openings through the floor. There are means for generating and directing hot wind toward the opening in the ceiling, and a means for recycling the air in the chamber to the hot wind generating means which is connected to the inlet side of the means for generating hot wind at one end and at the other end to one of the openings in the floor part of said chamber. Also, a means is provided for introducing fresh air into the system and is connected to the recycling means.
