Diagnostics of Polymeric Materials Coloring Systems

摘要

The diagnostics of the color formation systems of thermosetting plastics LasilCast4, Synthene PR 403, Synthene PR 2000 was carried out. The process of selection the concentrations of coloring media for coloring thermosetting plastics in bulk is considered. An approach for improving the coloring of polymers using colour management systems based on the use of subtractive coloring media (CMY + K) is proposed. The cause-effect relationships of the influence of colorimetric parameters of pigment pastes on the process of polymers coloring were established. To describe the reproducible colors, it is proposed to construct a body of color gamut based on the data on the color-forming components. The results of the color gamut of the multicomponent polyurethane color formation system using viscous pigment pastes are presented. The technique of diagnostics coloring systems for polymers-thermosetting plastics is proposed, which provides visual clarity and high accuracy in predicting color reproduction during polymer coloring. The accuracy is confirmed by the experimental data and the calculated values of the color difference. It is shown that the system of color formation on the basis of the Synthene PR 403 polymer has the broadest color gamut.
