Data on studying atmospheric emissions and pollution of the working space by lead compounds in the production of glass and crystal glass articles are given. Various logistic and engineering measures that make it possible to reduce toxic emissions and improve the ambient medium are considered.
The process of chemical corrosion of glass is investigated using a methylene blue indicator. Kinetic and concentration dependences for adsorption of the colorant by silica acid gel are obtained, including the process on the bottle inner surface. Causes and the mechanism of origin of sediments in...
A porous ceramics based on strontium zirconate synthesized from zirconia of grade TsRO-2, baddeleyite powder of grade PB-1, and strontium carbonate with the use of a burning-off additive, namely, bead polystyrene, is described. It is shown that porous zirconate ceramics can be produced by a...
Certain regularities of the motion of glass melt flows in a highly efficient furnace for container glass are studied employing the method of physical modeling of the glass melt hydrodynamics.
Various phenomena and processes in glass production are considered taking into account surface and volumetric factors. Kinetic analysis of reactions of K 2 O – PbO – SiO 2 system glasses with a reducing flame and the molding process under isothermal and non-isothermal conditions is carried...
Data on the design and application areas of small-sized glass-melting furnaces for melting various-purpose glasses are supplied.
The experience of the Saratov Institute of Glass in replacing Tashlinskoe sand by local sand with a variable chemical composition in the production of light- and heat-protective float glass is described. Practical recommendations are presented.
Data on studying toxic emissions during container-glass melting based on various types of fuel are provided. It is demonstrated that emissions decrease when natural gas is used as the fuel.
The possibility of fabricating unfritted opaque glaze roasted at a high temperature (1200°C) for ceramic sanitarware is considered. The glaze contains finely disperse zircon and possesses high whiteness.
The principles of deposition of titanium nitride coatings on parts of glass-shaping machines using ion bombardment in vacuum are considered. Results of industrial testing of parts and tools are described.
