Title:
DRYING METHOD
Document Type and Number:
Japanese Patent JP2005037017
Kind Code:
A
Abstract:
To provide a drying method capable of preventing the disorder of a coating film surface, and obtaining a precise coating surface.
The temperature difference between a face side and a back side of a coating film is suppressed to be small by heating a base material 1 not only from a coating surface side but also from a back surface side, and the coating film is dried under a condition that the Marangoni number Ma and the Rayleigh number Ra in the coating film do not exceed respective critical numbers. Disorder of the coating film surface is prevented to obtain a precise coating surface by suppressing generation of Marangoni convection and Benard convection in the coating film.
