Studies of the properties and structure of mineral wool energy-efficient products /Scientific research of the SCO countries: synergy and integration
In the modern world, increased energy efficiency and reduction of energy intensity are especially important in the construction industry, which largely determines the development of production as a whole. Reduction of energy intensity can be achieved through the use of efficient thermal insulation materials and products based on them and, in particular, mineral fiber products: based on glass or rock wool. The properties of these products are significantly influenced by the type and method of introduction of binder, and one of the ways to reduce the energy intensity of their production is to reduce the temperature of heat treatment of these products. The purpose of the research presented in this scientific paper is to analyze the existing types and methods of introduction of binders, aimed at reducing the energy intensity of the manufacture of products based on stone wool. As a result, a digital model linking the strength of cured contact with varying factors is obtained and a nomogram for solving the forward and inverse problem of digital modeling is developed, as well as optimal intervals of values of the most significant factors are determined: binder consumption 3.75%; content of latent component in the range from 3.6 to 4.0% of the binder mass at the temperature of heat treatment 120-140 o C.
