| Popis: | This paper reports results of research into the application of pharmaceutical glass waste, which is a mixture of medical ampoules, in the production of ceramic tiles. Disposal of such waste reduces the negative impact on the environment and contributes to saving mineral raw materials. At the same time, environmentally safe handling of ampoule forms of pharmaceutical glass waste at the disposal stage implies the removal of drugs’ residues from them. The appropriateness of using glass ampoules cleaned from drug residues as a fluxing component of engobe coatings for glazed ceramic granite is experimentally and theoretically substantiated. Comparative analysis of the charge composition of engobes of various manufacturers and of different chemical compositions of fluxing materials, which are components of these engobes, was carried out. The chemical composition of pharmaceutical glass waste was found to suggest the similarity of the basic properties of melts of these wastes and engobe glass frit. The paper considers the dependence of viscosity of the melts of engobe glass frits on the temperature. It was found that by the estimated values of viscosity of melts and experimentally determined characteristics of fusibility, glass waste can serve as substitutes for expensive engobe frits, when used with other traditional components of engobes. The chemical composition of the waste and of the basic engobe frit was determined by the method of X-ray spectrometry. Fusibility characteristics were explored using the thermoscope MISURA. Temperature coefficient of linear expansion of glass materials was determined with the use of the dilatometer LIL402PC. The research into the development of engobe coatings using pharmaceutical glass waste for the technology of glazed ceramic granite at firing temperature of 1185°C was carried out. The rational charge composition of glazed engobe with a whiteness of 76% was determined, which contains 30% by weight of glass waste. The engobe tiles with water absorption of 0.3–0.4% and the limit of flexural strength of 52–54MPa were obtained |
