Title:

FINE PARTICLE ARRANGEMENT CONTROL METHOD AND ITS DEVICE

Document Type and Number:

Japanese Patent JP2005118984

Kind Code:

A

Abstract:

To change the evaporation time of a dispersion medium, by extremely shortening the evaporation time of the dispersion medium, by holding a shape by controlling arrangement of fine particles in the two-dimensional direction and the three-dimensional direction on a base board.

This fine particle arrangement control method holds a controlled arrangement shape of the fine particles on the base board for increasing the fluidity of a mixture by uniformly dispersing a supercritical fluid by mixing the supercritical fluid in the mixture of the fine particles and the dispersion medium. When the supercritical fluid in the mixture is jetted in the atmosphere and rapidly expands and volatilizes when jetting the mixture on the base board from a nozzle, and when the fine particles collide with the base board or when the fine particles collide with each other when the dispersion medium evaporates and the fine particles are bared, energy is discharged, and the fine particles and the base board or the mutual fine particles are adhered by the energy. The fine particle arrangement control device is composed of a pressure adjusting part for adjusting supercritical carbon dioxide to pressure suitable for a spray, an agitating part for mixing the supercritical carbon dioxide, the fine particles and the dispersion medium, and a spray part for spraying the mixture of the supercritical carbon dioxide, the fine particles and the dispersion medium.
