For the first time, the results of studies on the development of a scale of desirability for assessing the competitiveness of wall building materials with glassy protective and decorative coatings are presented. The quality indicators of wall building materials with glassy protective and decorative coatings, obtained by the method of plasma reflow, have been studied. Using the relative indicators of properties, a complex quality indicator was calculated, which characterizes the technical level of quality of the glassy protective and decorative coatings under study, obtained by the method of plasma reflow.

It is noted that maintaining within a given level of the content of iron oxides in glass and the optimal ratio between oxides of ferrous and ferric iron increases the efficiency of glass furnaces. More stringent requirements for the quality of raw materials for the production of float glass have been formulated. The magnitude of fluctuations of iron oxides in the raw material and its influence on the stability of the melting and glass production process have been revealed and analyzed. The technique of introducing an iron-containing component (crocus) into the charge to smooth out sharp fluctuations of iron oxides in the raw material is described. The relationship between changes in the temperature of the gas space, molten glass in the furnace and the total consumption of gas fuel with the nature of changes in the amount of FeO and Fe
2 O
3 is indicated.

Some methods of statistical analysis used to control the quality of glass batch are considered, and factors influencing its temperature and humidity are determined. An assessment of the accuracy of the charge moistening process was carried out and a causal diagram of the moisture instability of a multicomponent mixture of raw materials was constructed. The use of a circular graph-radar for the analysis of the chemical composition of glass by deviations in the content of basic oxides is proposed.

The technological factors have been studied that have an intensifying effect on the processes of hardening and structure formation in the system of quartz sand - liquid glass. Optimized temperature and humidity conditions for the hardening of the compositions, the dispersion of the filler, the type and amount of the modifying additive, the quantitative ratio of the components of the raw mixture. High-silica liquid-glass composites for construction purposes with increased mechanical strength and water resistance have been developed.

The influence of the quality of such a main component of the charge as cullet on the final product - float glass is shown. The analysis of the quality of cullet (own and imported), the constancy of its quantity loaded into the furnace, for the quality of float glass was carried out. Based on the analysis, it was concluded that it is necessary to create centralized production facilities for the collection and processing of float glass scrap using advanced technology and high-performance equipment to provide high-quality cullet for the glass industry enterprises of the Russian Federation.
