An integrated model of the raw material mixture high-temperature treatment process to produce foam glass. Problem statement

Abstract

The paper considers the demanded porous building materials, as well as the main stages of their production technology. The advantage of block foam glass as a porous building material compared to other building materials is shown, and the basic technologies for its preparation are considered. It is noted that the priority technology for the foam glass production is a two-stage powder production technology. A schematic diagram of the foam glass production according to the two-stage powder technology is presented, where the cycle of heat treatment of the raw mix for producing foam glass is noted and the sequential steps of the process are considered, in which the raw material charge is exposed to high temperature. The physical and chemical features of the phenomena inherent in the individual phases of the raw mixture transition from heating, foaming and annealing to the finished material (foam glass) are analyzed. Fragmentation of the scientific ideas about the foam glass heat treatment process is noted; it hinders the adequate and optimal technological modes’ development for the foam glass production, which directly affect its further cost. The necessity of developing a general methodological approach to the study and modeling of high-temperature maintenance regimes of the raw material mixture TT for producing foam glass, the creation of rational technological approaches to the producing block foam glass process as a part of its production concept, the identification and study of the TT high-temperature maintenance regimes laws with such models and predicting the final operational properties of the finished material are emphasized.
