Abstract
In a manufacturing method for manufacturing a dispersion body, a plurality of types of solid particles, water, and a liquid dispersant are mixed. In the manufacturing method, at least two types of the solid particles and at least one type of the dispersant that are selected based on a material type selection method are used, and at least an optimal amount of the dispersant that is determined based on an optimal amount determination method is added and mixed. The material type selection method is based on a Hansen solubility parameter distance to water, Hansen spheres of the solid particles, and a Hansen sphere of the dispersant.

A manufacturing method for manufacturing a dispersion body by mixing a plurality of types of solid particles, water, and a liquid dispersant, the manufacturing method comprising:
- using at least two types of the solid particles and at least one type of the dispersant that are selected based on a material type selection method for selecting the solid particles and the dispersant such that Hansen spheres of at least two types of the solid particles and a Hansen sphere of at least one type of the dispersant mutually overlap, and a Hansen solubility parameter distance to water of at least one type of the solid particles of which the Hansen spheres overlap that of the liquid is greatest among all solid particles used in manufacturing of the dispersion body;
- and
- adding and mixing at least an optimal amount of the dispersant that is determined based on an optimal amount determination method for fabricating a mixture by mixing all materials that are used in the manufacturing of the dispersion body, excluding the dispersant, measuring viscosity when the dispersant is gradually added to the mixture while an added amount is increased, and setting, as the optimal amount, the added amount when changes in the viscosity begin to stabilize.
