DEVELOPMENT OF ADAPTIVE SYSTEMS FOR CONTROLLING THERMAL PORIZATION OF ALKALI-SILICATE THERMAL INSULATION PRODUCTS AND CLARIFICATION OF THE FEATURES OF ITS REPRODUCTION MODES

Abstract

The proposed research is aimed at developing and implementing an adaptive system for zoned control of heat treatment modes of the initial silicon-containing high-modulus raw mass and clarifying the conditions for reproducing highquality waterproof thermal insulation products with a rigid porous structure based on soluble glass and mineral fillers of technogenic origin (waste of the coal-energy complex). The innovativeness and relevance of the proposed technical solutions are based on the properties revealed by the authors, which are manifested by the compositions; operational features and efficiency of this type of inorganic insulation with a low value of relative density, thermal conductivity capable of maintaining sufficient structural strength; easy controllability of the foaming and hardening processes within a wide range of composition compositions. The proposed variant of the type of control, the reproduction of the conditions of technological transformation, its modes (sequence, duration, stages, temperature limits, intensity and speed) determine the peculiarities of the behavior of the processed alkalisilicate composite systems. This variant differs from the known solutions in the composition, recipe of the initial raw material mixture, sequence and modes, stages of formation of the target product, technological equipment, developed and applied means of controlling the production of products, hardware and software solutions for their management. The work performed consists of three interconnected search empirical stages, based on the practical implementation of the sequential methodology and results of obtaining target samples according to the developed thermal production regulations using the proposed complex of hardware and software. The metrological quality of the obtained results and their reliability at the stage of clarification and identification of functional properties and dependencies valuable for production were ensured by the use of programmable precision thermal control systems of our own design; on a production scale – by selecting appropriate serial means.
