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.

DEFINITION OF EFFICIENCY OF POLYMETHYLPHENYLSІLOXANE-BASED FIRE PROTECTIVE COATINGS FOR STEEL BUILDING STRUCTURES

The article deals with the current problem of determining the fire resistance of protected steel elements of building structures. Based on the analysis of literary sources, the main methods for increasing the fire resistance of steel structures are considered, as well as the use of fire retardant coatings based on polymetallophenylsiloxane. Analytical studies were conducted to determine the time of fire protection of the coating, compared to unprotected structures. The results show that the limit of fire resistance of protected steel constructions is increased 2-4 times, depending on the thickness of the application.
