MODIFICATION OF SIO2-B2O3-NA2O SYSTEM WITH CAO, MG PHENATE BAO OXIDES AND THEIR PROPERTIES.
Author: Babaev Zabibulla Kamilovich, Matchanov Sherzod Kamilovich, Buranova Dinara
Abstract:
Тhe effect of alkaline earth oxides on the physicochemical properties of easy-melting vitreous enamels for architectural and building products are studied. It was established that with the increase of ionic radions of the elements of modifier introduced into the vitreous decreases the viscosity of the molten glass. Also, the dependence of surface tension on the vitreous content of alkaline earth oxides is increased while output modifiers limits up to 20%.

MODEL OF OPTIMIZATION OF TECHNOLOGICAL REGIMES OF OILEXTRACTION PRODUCTION FOR THE MINIMUM COSTS
Author: Abdullayeva G. K.
Abstract:
In the stochastic manufacturing process conditions and classification of end products of oil extraction production by intersecting quality areas, manufacturing costs can be reduced by varying the values for the number of modes and their coordinates. 25 Built in the model optimization mode technology is designed to surround the purposes of (current) planning production of oil extraction enterprise products.
DEVELOPMENT OF STRUCTURE OF CERAMIC BRICK WITH REGARD TO ENVIRONMENTAL FACTORS
Author: Babayev Z. K., Djumaniyazov Z. B., Yaqubov Y. X., Xudayberganov E. X.
Abstract:
Preliminary studies have established that the process of burning ceramic bricks containing coke-fines as burn-in additives proceeds much faster, with minimal energy expenditure than the traditional method. Also, under these conditions, it is established that the coke fines serve as a reducing agent and accompanies the decomposition of difficult to decompose salts (Na2SO4, CaSO4), which eliminates such negative phenomena as high education. The reducing medium also positively influences the reduction of iron oxides (Fe2+ to Fe+) contained in loess-like loam, the chemical ratio of which is Fe+ more active than Fe2+, which predetermines the acceleration of the formation of the liquid phase. Further heating of the sintered material layer leads to a decrease in the viscosity of the liquid phase, thereby enveloping the grain of the refractory component, or dissolves in them, forming new chemical compounds.
THE MODEL OF OPERATIONAL CONTROL OF THE PRODUCTION PROCESS IN COTTON PROCESSING ENTERPRISE
Author: Firnafas Y.
Abstract:
Mathematical formalization of the test process is reduced to the construction of the static model of operational control of technological progress of the
primary processing of raw cotton, thus it is considered a fixed process parameters and usage of digital technological modes.
