Full textThesis for a Doctor of Science Degree in Specialty 05.17.11 – Refractory Non-Metallic Materials Technology, State Higher Educational Institution "Ukrainian State University of Chemical Technology", National Technical University "Kharkiv Polytechnic Institute", Kharkiv, 2019. The dissertation is devoted to creation of physicochemical bases of technology of ecologically safe protective and decorative glass-enamel coatings of wide color scale on steel and non-ferrous metals, development of principles of regulation and prediction of their color. As a result of the research on the topic of dissertation the following scientific results were obtained: - scientifically substantiated and experimentally proved that the production of lead-free enamel coatings on non-ferrous metals is possible on the basis of the Na₂O – BaO – B₂O₃ – SiO₂ glasses, by the complex of defined properties and the ability to form the highest quality coatings on a copper basis the selected region of the base system, mol %: Na₂O – 24,2–40,5; BaO – 5.0–10.0; B₂O₃ – 15.2–30.5; SiO₂ – 24,0–53,5, which in comparison with the limits of these components in known compositions of lead-free enamels, is characterized by a 2-fold increase in the content of B2O3 and a relatively small content of SiO₂; - the basic tendencies of color change of glasses of Na₂O–BaO–B₂O₃–SiO₂ system has been established, which differ significantly in chemical composition and has colored by ionic dyes, taking into account the structural features of glasses and their acid-basic properties. They has been evaluated by two calculated structural parameters: fSi is the degree of connectivity of the silica framework and Ψв is an indicative index of the coordination state of Boron in the structure of the glass. It had proved that there is a significant correlation between the colors λ and Ψv had proved for glasses colored CuO r * = - 0,83 and CoO r * = - 0,87 and weak – for glasses colored K₂Cr₂O₇, -r * = 0,5; - the patterns of coloring of one glass matrix and enamel coatings on its basis in the system R₂O–BaO–ZnO–Al₂O₃–B₂O₃–TiO₂–SiO₂ by a series of ionic dyes has been founded. Regardless of the content of the dyes, they give the same color tone to the glass and coatings based on these glasses, namely: CuO (1.0–3.0 wt%) λ = 489–494 nm (blue-green), Fe₂O₃ (0.5–2 wt%) λ = 575–585 nm (yellow), K₂Cr₂O₇ (0,5–2.0 wt%) λ = 570–576 nm (yellow-green), CoO (0.5–1.0 wt%) λ = 441–463 nm (blue-violet), NiO (0, 5-1.0 wt.%) λ glass = 559′ – 571 nm, λ coatings = 598–629 nm (brown). It has been proved that in the degree of color intensity of glasses and coatings based on them, the dyes has been arranged in the following sequence: CoO> NiO> CuO> K₂Cr₂O₇ > Fe₂O₃; - for the first time, the mechanism of silencing of transparent matrix enamel glass in R₂O–BaO–ZnO–TiO₂–Al₂O₃–B₂O₃–TiO₂–SiO₂ system with the introduction of MoO₃ has been established, which results in the phenomenon of opalescence, namely: due to diffraction at propagation of waves in micro inhomogeneous medium in which the particle size of molybdenum (VI) oxide is 0.05-0.15 μm less than the wavelength of white light; - for the first time, the dependence of the diffuse reflection coefficient (CDR) of enamel coatings on the chemical composition of enamel frits, obtained by processing the experimental sample 471 of the enamel frit composition by multiple correlation analysis, which is presented in the form of a mathematical model that allows you to calculate the chemical composition of the enamel coatings with a given CDR; the correlation coefficient between experimental and calculated values is 0.98; - using the idea of introducing into any material (glass, pigment, sitall, metal) certain components in a small amount to modify its properties, the following has been first discovered: "small addition" of Fe₂O₃ in the amount of 0.25 wt.% in the composition of lead-free enamel glasses based on the base system Na₂O–BaO–B₂O₃–SiO₂ and 1 wt.% in the composition of fluorless glass enamels based on the basic system Na₂O–B₂O₃–SiO₂ activates the processes of differentiation of the segregation-dropping structure of glass, which allows to increase the intensity of opaque coatings by 1.5–2.5 times, as well as to improve the optical-color characteristics of pigment-colored glass coatings, in particular, red. "Small addition" of ZrO₂ in the amount up to 1 wt.% in the composition of low-fluoride titanium enamel promotes the active release of anatase in the coating during firing and improving its optical characteristics; -with the help of a dedicated COLOR GLASS computer program that automatically calculates color coordinates x y, color tone λ, color purity P, and maps the color characteristics of materials to the СIE graph, it has been first demonstrated that the picture of the location of the color points, first, you can make predictions about the equilibrium that is formed between the ionic coloring complexes during the melting of glass, and secondly, about the color potential of the pigment mixture. - for the first time in the field of technologies requiring high temperatures, the dependences of the color coordinates of the enamel coatings on the composition of the pigment mixture in the form of polynomial mathematical models has been established, which made it possible to solve the complex material-coloristic problem of finding the ratio of pigments to reproduce the color of the sample with the specified color characteristics. The practical significance of the obtained results: - the compositions of enamel glasses for non-ferrous metals, which do not contain Plumbum - one of the most harmful for the environment element, had been developed; the basics of technology of obtaining products with their use had offered. New enamels of a wide range of colors with varying degrees of transparency had been created on the basis of matrix transparent enamel and they had characterized by the same firing interval of 780-820 °C, which makes the technology of obtaining artistic and jewelry easier. Enamels had been tested and recommended for implementation in the production of artistic products in the workshop, which locates in the structure of the Museum of Ukrainian Painting (Dnipro), as well as at the jewelry company, Diadema, Vinnytsia. The enamel coatings palette and their products had presented during a report at the 24th International Congress of Enamels in Chicago in 2018. According to an international agreement between the Ukrainian State University of Chemical Technology (Dnipro) and Richemont International SA Varinor SA, Delmont, Switzerland, enamel glass powder and enameled copper samples had been made and handed over to the customer; - a catalog of color samples, which presents the glass base, the number of dyes, opacifiers, reducing agents and the optic-color characteristics of enamel coatings which do not contain Plumbum, has been created. The color name was set in accordance with the color name of the RAL system. The palette of designed enamels of jewelry and artistic purpose includes transparent matrix enamel and 53 colors: yellow-red, blue-green, olive-mustard, pastel and brown-black; - a series of compositions of white and light-colored titanium enamels containing reduced amount of Fluorine, has been developed, also the composition of fluorless frites to obtain brightly colored enamel coatings pigmented way of color, which were fused and passed extensive testing in production conditions factories for the production of enameled household products, has been synthesized. Technological features of production of the enamels offered permits to carry out high-temperature operations of melting at 100oC below the known ones, and firing of coatings – by 30-50 °C, which is very relevant in the era of total saving of fuel and energy resources. Low-fluoride light-colored cream and gray-blue enamels has been introduced at "Novomoskovsk dishes"; - for the first time for the technology of enamel coatings on steel, a method of color modeling has been developed, through which a color triangle-nomogram has been constructed for the production glass base and pigments of yellow, red, blue, by which the required color is specified and the necessary ratio of pigments is calculated. The color modeling method is versatile and can be applied to a wide range of silicate materials: glazed ceramic coatings, colored building materials, and more. The introduction substantiates the relevance of the dissertation topic, formulates the main purpose and objectives of the work, presents the scientific novelty and practical value of the obtained results. The first section provides an analysis of the patent and scientific and technical literature concerning the production of environmentally safe enamels of a wide color range, the current state of production of colored enamels and the control of their color indices, the mechanisms of color of glass and enamels and factors affecting color formation. The second section provides the basic concepts and definitions used in the work, as well as methods for investigating the physicochemical properties and structure of glasses and coatings and their color characteristics. The third section presents studies on the development of environmentally safe enamels for copper and the prediction of their color characteristics. The fourth section presents the results of research on the development of fusible titanium enamel which would meet the requirements of current standards and be burned in resource- and energy-efficient production conditions and be the most environmentally safe for the environment. The fifth section is devoted to the research on the development of enamel frits that do not contain Fluorine and used to produce brightly colored enamel coatings for household products. The sixth section presents the results of the development the color modeling method. Reproduce, and even more so predict, color with predetermined color characteristics is an extremely complex multifaceted material science problem, even if glass and coating formulations, modes of melting and firing are known. In the seventh section the results of industrial testing, realization and implementation of the received materials has been presented.
