Functional Protective Coatings for Steel Architectural Construction Panels

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.

Chemically Resistant Glass-Enamel Coating for the Protection of Steel Pipelines

At present, the problem of obtaining a defect-free corrosion-resistant glass-enamel coating for steel pipelines is extremely urgent. In this paper, the development of a corrosion-resistant glass-enamel coating for steel pipelines is presented, as well as the technical and operational properties of synthesized glass-enamel coatings are investigated. The composition of the enamel coating is developed, which has a high adhesion index, chemical resistance to aggressive media and can be recommended for introduction in the production of enameled pipes.

Crystallization Peculiarities of White Glass-Enamel Coatings for Steel Products

The aim of the research was to study the influence of small additives on the crystallization of titanium-containing phases in glass and the influence of the process parameters on the whiteness of the covering glass enamel coatings. A number of compositions of initial glasses (frits) were synthesized to produce glass coatings with high whiteness. Their physical and chemical properties were analyzed. A titanium-containing glass enamel coatings were developed, the composition of which contains compounds that promote bulk crystallization, which ensures a high whiteness index.

Glass-Ceramic Materials and Coatings Providing Steel Household Products with the Desired Properties

The possibility of production of white cover glass-enamel coatings for steel products has been considered. A number of compositions of glass-enamel coatings has been worked out. The obtained samples have been subjected to tests for corrosion resistance, temperature resistance and whiteness index. The peculiarities of crystallization in white cover glass-enamel coatings have been revealed. It is shown that the produced cover glass-enamel coatings for steel products conform to all requirements of GOST R 52569-2006. The application of RGB color model has been considered to determine the color hues of the white enamel coatings.
