Investigation of the processes of titanium dioxide dispersion in the presence of various surfactantsAn essential factor affecting the effectiveness of protective and decorative properties of paint and varnish compositions due to the use of surfactants with inhibitory activity in their formulations, as well as the ability to form permanent (cohesive, adhesive), decorative, insulating films based on their selective adsorption, seems to be a promising improvement of the coating performance characteristics.The mechanism of their physico-chemical effects on the interface and the dispersed medium as a whole depends on the nature of the surfactants and the contacting phases, as well as their quantitative ratio.The paper presents the results of experimental studies of the regularities of the processes of titanium dioxide disaggregation in an aqueous dispersion medium in the presence of three types of surfactants.Introduction of three versions of surfactants intensify processes of disaggregation of particles of titanium in an aqueous dispersion medium.The maximum dispersing effect with respect to titanium dioxide is set for sodium polyacrylate solution.The average diameter of the solid-phase particles in comparison with the characteristics of the base composition decreased from 13 to 4 microns, when this modified additive was introduced at the level of 0.25 g/L.
