The wet coating exchanges heat with the monotonous hot gas, absorbing the heat of the monotonous air, and the liquid on the surface of the coating Glue spreader continually evaporates into steam into the air, and the vapor is carried away by the monotonous air.
When the liquid content of the wet coating is relatively high (above the critical moisture content), the speed of the vaporization of the Glue spreader depends on the following factors: the air velocity of the surface of the AGlue spreader; the humidity of the monotonic air of B; the temperature of the monotonic air of the C . When the coating is monotonous until its moisture content reaches the critical moisture content, the vaporization rate of the Glue spreader's appearance depends on the looseness of the liquid inside the coating Glue spreader.
The internal liquid loose process of the Glue spreader, because of the vaporization of the coating Glue spreader, the concentration of the liquid on the surface of the coating Glue spreader becomes smaller, and the liquid inside the coating Glue spreader is continuously loosened to the surface of the Glue spreader. The coated coating in the transition stage enters the monotonic box, and the Glue spreader appearance of the membrane gradually lowers the temperature due to the vaporization endotherm of the solvent or water, and there is a leveling process.
