Mironova G. Direct-on monofrit vitreous enamel coatings for steel water heaters

Object of reserch: technology for direct-on monofrit low-melting chemical and thermal resistant vitreous enamel coatings by powder electrostatic technology (POESTA) .Purpose of research: determination of physical and chemical properties and performance characteristics frit glass coatings performed using standard and special techniques described in the relevant section. Mathematical processing of experimental data and optimization of the glass-enamel made by methods of mathematical approximation and experimental design. Calculations physical and chemical properties of coatings glass-enamel conducted using computer processing (MathCAD). Physico-chemical properties and performance of materials research glass coatings determined in accordance with the requirements of existing regulations. Theoretical and practical results: theoretically and experimentally proved the possibility of obtaining monofrytnyh direct-on waterresistant low-melting glass-enamel coatings for technology POESTA by synthesis of chemically resistant glass matrix base with desired structure and properties and ensuring its maximum structural strength through the use of optimum ratios structurally modifying additives and components of complex adherence activator.Perfected technological parameters of melting frit developed warehouse receipt finely dispersed powder of hydrophobic kapsulyantom, mode of application and firing bezґruntovoho monofrytnoho fusible chemically and thermally stable skloemalevoho coverage. Novelty: set limit values ??of the effective concentration of modifier N4, which ensures compliance in glasses system R2O (Na2O + K2O) - RO (CaO + BaO) - Al2O3-B2O3-SiO2 most solid frame sklomatrytsi base and given the level of performance properties strukturnozalezhnyh through established relationships skloutvoryuvachiv and modifiers. The degree of approbation: Based on the positive results of pilot tests developed bezhruntovoho monofrytnoho cover held at LLC "DSO and EPA" (c. Donetsk) and enterprise EMO FRITE (m. Celie, Slovenia) recommendations for implementation in the production of water heaters enamel steel tanks.
