Journalism Department popup.description2 The dependence of aggregative stability of titanium dioxide aqueous suspensions and zeta-potential of its particles on pH medium in the solutions of anionic surfactant and non-ionogenic surfactant and their mixtures has been investigated. The conformation changes of a macromolecular skein of polymethacrylic acid have been determined at its transition from solution to the solid surface. The redispersion process of powders of aluminum oxide and titanium dioxide in distilled water, 1,4-dioxane, ethyl alcohol and the industrial surfactants (DINORAM, E-30, EMAL-270D, OC-20) has been investigated and the influencing aggregate processes on granulation factors of suspensions have been estimated. The influence of the surfactants (TRITON CF-10, ATLAS G-3300, TAMOL-731) on compression of the package high-dispersion parts of the titanium dioxide, the vollastonite and the chalk into the sedimentation residues, which have been formed from theirs water suspensions have been studied. The role of the processes ofthe redispersion and the parts coagulation in the formation of the coagulation structure of the residuum is shown. The dependence of density of randomly formed structure of spherical particles of the different sizes on a ratio of particle sizes and their quantities has been studied using the method of physical simulation of random packing.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
