“…A several compositions for fire-resistant curtains have been developed (table 1). Hypothesis is that the charred layer which forms as a result of exposing an intumescent composition to high temperatures should increase the fire resistance limit of the curtain due to the charred layer's high thermal durability [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. An intumescent compound swells and increases in volume as a result of heating; swelling coefficient is used to measure the efficiency of a compound.…”

The paper overviews the way by which intumescent fire retardant compositions act as fillers in fire-resistant automatic curtains. A several intumescent compositions, which form a heat-isolating charred layer when they are exposed to high temperatures, were produced and applied to the mineral-fabric basis of the curtain. Fire-protective properties of produced materials were assessed and compared with foreign specimens. Swelling coefficient and material’s fire durability were considered as operating parameters. The developed specimen which performed the best during fire tests was sent to accredited laboratory. It was proven, using standardized methods, that it’s fire resistance limit reaches 30 minutes. This proves an effective contribution of an intumescent compound and opens new ways of using them in fire curtains manufacturing.

“…Fireproofing charring compositions are frequently used and well-known: first patents were published in 1930s [1,2]. A significant amount of researches [3][4][5][6][7][8][9] which purpose is to improve fire resistance of building constructions and materials shows that the work on enhancing the properties of swelling compositions continues nowadays. As intumescent materials exist for such a long period of time, researchers have found the optimal technological complex for producing intumescent compositions which ensure effective fire protection of constructions and materials.…”

The enhancement of operating properties of intumescent fire-protective compositions

et al. 2018

The paper overviews the operational properties of charred layers which are forming as a result of thermolytical synthesis of intumescent coatings, and the ways of enhancing those properties using different additives mixed with initial intumescent composition. Methods including differential thermal analysis, thermogravimetric analysis, microscale calorimetry and scanning electron microscopy were used to investigate the modified intumescent compositions and the properties of charred layers formed from them. Results show that additives tend to change the microstructure of char which undergoes some transformations; it is proven by increase in volume and stability. Also it is shown that melamine-aldehyde resin was detected in the microstructure of char, and it is a step forward in forming a holistic conception of intumescents operating.

“…At present, there is a world trend in the high-rise construction development. Such buildings are subject to special requirements for ensuring fire safety, especially in terms of the construction material quality control and the organization of effective evacuation measures [1][2][3][4]. Particular attention is also paid to space-planning solutions [5], the flame effects on the structures operation [6][7][8][9] and the need for additional fire protection [10][11][12][13][14][15].…”

The article explores a new phased evacuation algorithm for high-rise buildings and structures. The necessity of using this evacuation type is justified by reducing of the human flow density, which minimizes the people injury risks and the crowd formation during the movement process. This type of evacuation prevents the appearance of clusters in local narrowing places (the floor entrance), as well as on stairway. The calculation model is made in Pathfinder PC. The scheme of organizing a phased evacuation is based on the separation of the evacuating people flows and the prevention of their crossing. The design scheme is given for the twenty-story section of a high-rise building. A detailed instruction describes the process of dividing a section into stages and determining the sequence of evacuation floors. The time delays table is calculated for each floor of the simulated twenty-storey section.
