A technology for the production of pigment based on spinel Co 1– x Mg x Al 2 O 4 is developed, where 0.67 ≤ x ≤ 0.80. The pigment has a bright blue color and is identical to the reference standard, although its cobalt content is 2 – 3 times lower.
A method for melting glass in a direct monohomogeneous thin flow of mechanochemically activated batch is proposed, which makes it possible to obtain homogeneous defect-free glass melt and intensify all stages of the glass-melting process.
Data on the improvement of the main technical and economical parameters of glass-melting furnaces in the leading countries and at the Salavatsteklo company are given. The authors consider the issues of upgrading the furnace design and operating regimes, which can increases the thermal and...
A method for the development of an environment management system using the process-oriented approach is considered taking the Borskii Refractory Works as example.
The optimum compositions of lead-free fluxes and enamels based on them are determined; their physiochemical properties are analyzed. The quantitative transformation of the enamel coating into solutions depending on the duration of the reactant effect is determined.
The factors affecting the efficiency of depositing glass enamel by electrophoresis is considered. It is established that the densest and most uniform coating are obtained on steel samples with preliminary deposited nickel. An optimum composition of slip is obtained and the conditions of...
Various designs of screw feeders for glass-batch components operating in the “precise” and “rough” proportioning modes are considered.
It is found that when clays are fired at underpressure, the reactions with the formation of volatile components proceed at a lower temperature, and the gaseous medium is reducing. At the same time, the sintering mechanism is modified, and the physicomechanical properties of the products obtained...
The formation of nanoparticles of semiconducting lead sulfide in silicate and borosilicate glasses matrices is investigated. The dependence of the size of PbS particles on the temperature-time heat-treatment conditions is identified. The effect of clarification arising in theses nanostructural...
A wide spectrum of traditional aluminosilicate refractory materials (chamotte, mullite-silica, mullite, mullite-corundum) for the construction and repair of glass-melting furnaces produced at the Borovichskii Refractory Works is considered.
