Title:
MEASURING METHOD AND MEASURING APPARATUS OF SOLUBILITY PARAMETER, AND SOLUBILITY PARAMETER CALCULATION PROGRAM
Document Type and Number:
Japanese Patent JP2019138779
Kind Code:
A
Abstract:
To measure the Hansen solubility parameter of a particle having a high density or a large particle of a micron order.SOLUTION: A measuring method of determining Hansen solubility parameters (δd, δp, δh) of a particle P includes: a classification process of classifying at least three types of solvents Sinto good or bad of the particle wettability of each solvent using a penetration speed method; a process of determining a Hansen particle in a three-dimensional space in which Hansen solubility parameters of the solvents Sare arranged in the position coordinates of (δd, δp, δh) on the basis of the classification result; and a process of deriving the position coordinates of the center of the Hansen particle as the Hansen solubility parameters (δd, δp, δh) of the particle P.SELECTED DRAWING: Figure 1
