Abstract:

Purpose. To assess an influence of climatic factors on properties of the reactive flame retardant coating “FENYKS STS” for analyzing steel building structures fire resistance for their use in coal mining.

Methodology. Scientific generalization and systematization, analysis of regulatory requirements for building structures fire resistance. Experimental study methods regarding the reaction of samples to heating, regulated by the regulations about fire protection DSTU–N–P B V.1.1–29:2010. Fireproofing of building constructions and general requirements and control methods. Mathematical and computer simulation of non-stationary heat exchange processes in “steel plate ‒ fire protection coating” system. Definition of thermophysical properties and protection ability of fire protection coatings based on solving direct and inverse heat conduction problems.

Findings. Based on developed two-layered physical and simulation models of fire protected steel plate, there was determined a coefficient of thermal conductivity of the “FENYKS STS” coating, which depends on temperature. The stable volumetric heat capacity has been defined. The efficiency of this coating for the protection of metal constructions has been proved. The influence of climatic factors on thermophysical properties of the coating and its fire protection ability is shown.

Originality. For the first time, the value of thermal conductivity for the “FENYKS STS” coating was determined after the influence of climatic factors during 3 years. The conclusion is that the fire protection ability of this coating does not change during that time.

Practical value. The results will allow making more accurate estimation related to fire resistance of fire protected steel constructions for a long-term use. The studies will be useful for designers and fire-retardant manufacturers, since they will allow calculating an effective fire-resistance thicknesses of the covering taking into consideration its time of use.
