The use of refractory materials in the artistic painting of glass panels

Abstract

Based on the analysis of the glass use evolution in architecture and construction, the need to improve or search for new types of glass as an element of the interior or exterior and ways to decorate them and the feasibility of using artistic painting was shown. The purpose of this work was its use in the manufacture of decorative elements for architectural and construction purposes with different surface textures and relief of polished float sheet glass while providing significant resource and energy savings with the use of refractory materials. The equipment and materials which were used included: Z. Bavelloni grinder; muffle furnace CGB-100.150.55-10- 380 for painting and annealing; sprayer type LVLP 1.3 mm INTERTOOL PT-0132 for spraying fine kaolin suspension; degreasing solution; panels from the polished float glass with the following chemical composition, wt. %: SiO2 — 73.0; Al2O3 — 1.0; Fe2O3 — 0.1; CaO — 8.6; MgO — 3.6; Na2O — 13.4; SO3 — 0.3 and 6 mm thick; refractory plates LYTX—264B and heat-resistant paper LYTX—236B from ceramic fibers. The coefficient of thermal linear expansion of glasses and refractories was determined using a quartz vertical dilatometer. As a result of the carried out researches the possibility of obtaining the set texture and three-dimensional relief of the surface of architectural and construction decorative products from polished float glass sheet by artistic painting with the use of refractory materials was shown. The factors that are decisive in the choice of such materials and their effectiveness were identified. Significant simplification and cheapening of the method of making decorative glass by artistic painting has been achieved due to the fact that to obtain each effect on the surface of the product it is enough to replace the refractory fragments of the composition and their arrangement instead of making new support plates. Further research of forming processes and phase generations in compositions based on applied and new refractory materials and their waste will contribute to a significant expansion of the range and areas of use the artistic and decorative glass products use.
