Based on the analysis of patent information, scientific and technical literature and developments of the Saratov Institute of Glass, a classification of protective nitrogen-hydrogen atmospheres by methods of their production has been compiled. The methods themselves are considered, and the main methods of cleaning gases from impurities are listed. A comparative analysis of the methods of obtaining a protective atmosphere is carried out, the advantages and disadvantages of each of them are revealed. Bibliography: 5 titles.
Information on modern glass compositions used for the production of continuous glass fiber in Russia and abroad is presented. The main physical and chemical properties of glass fibers and their areas of application are considered. Tab. 3, bibliography: 21 titles.
An analytical approach to determining the impact strength of laminated glass is considered. A method is proposed to reduce material consumption, energy consumption and the cost of a package through the use of glass with induced surface stresses. Tab. 2, ill. 2, bibliography: 4 titles.
Based on the analysis of patent information, scientific and technical literature and developments of the Saratov Institute of Glass, the influence of the gas environment on the physical and chemical processes of forming float glass was determined. Techniques for regulating physicochemical conditions in the melt bath are considered. The possibilities of purposefully changing the composition and properties of the float glass surface by exposure to a gaseous medium are shown. Il. 1, bibliography: 4 titles.
Using EPR, it was found that the main centers of accumulation of negative charge are electrically active phosphoric acid radical ions PO 3 of the electronic type. Most of the studied phosphate glasses are capable of accumulating such a charge. However, the most effective of the alkaline earth modifiers is magnesium. The results obtained make it possible with a high degree of reliability to design the compositions and technology of inorganic glasses with a given set of operational properties. Tab. 1, ill. 2, bibliography: 17 titles.
The results of studies on plasma spraying of glass from rods onto high-quality dishes are presented. It is shown that in the process of decorative plasma treatment, a coating with good consumer properties is formed. Tab. 3, ill. 1, bibliography: 4 titles.
The conditions for the distribution of the indicator - yttrium oxide, introduced with the charge, over the width and thickness of the glass ribbon during its production on the metal melt are considered. It is shown that in the thickness of the strip, the marked newly welded molten glass is located in the form of luminescent layers, the number of which increases with time up to a uniform distribution of the indicator in the strip. It was found that the decisive role in the distribution of the labeled molten glass in the glass ribbon is played by the transverse convection of the molten glass. Tab. 2, bibliography: 6 titles.
The proposed method for calculating the impact strength of triplex proved the possibility of further improving its design based on glass subjected to complex heat treatment. Il. 2, bibliography: 3 titles.
Possible stages of interaction of glass with a film-forming solution are considered. The influence of the amount of acid and water in the solution on the destruction of glass is shown. An analysis is given of the relationship between the amounts of Na 2 O and SiO 2 with each other and with the width of the transition layer. Tab. 1, ill. 3, bibliography: 5 titles.
Using the method of mathematical statistics, a model has been obtained in the form of a linear regression equation, which adequately describes the change in the light transmission of float glass colored in the mass in the visible and IR ranges, depending on the change in the main technological factors. Tab. 1, ill. 1, bibliography: 2 titles.
