Abstract
Currently, enameled steel products are becoming very popular in construction, since they have a number of valuable properties that noticeably distinguish enameled architectural and construction panels against the background of other facing building materials. Also, extremely urgent is the problem of obtaining glass enamel coatings for architectural and construction panels with high properties. In the work, glass-crystalline enamel coatings in the system R2O–RO–B2O3–Al2O3–SiO2–TiO2–P2O2–F- were studied, the features of their formation on facing steel panels were revealed. The physicochemical and aesthetic-consumer properties of the developed enamel coatings have been investigated. The influence of the chemical composition of titanium-containing glass and the crystallization process on the whiteness index of white coating glass-crystalline enamels and the characteristic color shade was studied using a spectrophotometric method using an RGB color measurement model. This method made it possible to accurately determine the shades of the obtained glass-crystalline enamel coatings for steel.
Highlights
Nowadays, energy saving is becoming increasingly important
The analysis of the obtained experimental data made it possible to establish that high indicators of whiteness, color and gloss of coatings are provided by the structural and morphological features of glass enamel having a glass-crystalline structure and containing a crystalline phase represented by titanium dioxide and a glassy phase represented by alkalialuminosilicate glass
The resulting colors make it possible to expand the scope of application of enamel coatings, improve their aesthetic and consumer properties
Summary
Energy saving is becoming increasingly important. In countries located in northern latitudes, in particular, Russia, this problem is especially acute, since they are characterized by a rather harsh climate and large temperature drops. To reduce heat loss and increase noise insulation, composite facing enameled panels with an internal porous filler in the form of a cellular polymer material or foam glass are used. The use of such panels is possible for cladding residential buildings, and for commercial and industrial real estate. These panels are resistant to high temperatures, while not emitting toxic substances; have high resistance to vandalism, namely abrasion, scratching and other mechanical influences; combine the strength of steel and the corrosion resistance https://doi.org/10.10 51/matecconf /202134602041 of glass; quite easy to maintain, which allows them to be used in metro stations, tunnels and underpasses
