AbstractAbout AuthorsReferences
The necessity of thorough mixing of the ceramic mixture components, which ensures the staining of wall ceramics without stains and color streaks, is shown. The main reasons for the dominance of the plastic molding technology of ceramic bricks at the present stage are considered. Prospects for semi-dry pressing of ceramic products with the use of lean silty loams, waste and by-products of industrial production in the technology of volume staining ceramic bricks are substantiated. A brief description of raw materials for ceramic mixture obtaining for the factory tests is given. Medium plastic clay, slime iron ore wastes were used as the basis, manganese and vanadium-containing technogenic additives were used as dyes. The processes of press powders granulation according to the patented technology and production of wall ceramics at working brick factory of semi-dry pressing are described. The results of the study of decorative and physical and mechanical properties of fired bricks, depending on the composition of the ceramic charge, are presented. The compliance of the obtained ceramic brick with the requirements of State Standard 530–2012 for grades M150–200 and its volume staining in brown and dark gray has been established. An assessment of the radiation safety of volume-stained ceramic materials is given according to the value of the total specific effective activity of natural radionuclides. An assessment of the effectiveness of the developed technology of volume-stained wall ceramics with a matrix structure, based on the results of the experimental-industrial testing in the factory, is given. The developed flow sheet of ceramic bricks production from clay and technogenic manganese concentrate is presented. The main stages of the full cycle of obtaining ceramic products in accordance with the process regulations for the design of the production of volume-stained ceramic bricks with a matrix structure are given.
