Abstract

The problem of using fabric products for building structures for the storage and transportation of explosives is to ensure their resistance to fire and durability during operation, but it is necessary to take into account the change in their fire-resistant properties. Reducing the flammability and developing non-flammable and non-flammable materials is one of the main areas of preventing fires and solving the problem of expanding the scope of application of these materials. Treatment with fire retardants has a significant effect on the spread of the flame, allows you to significantly reduce the smoke-generating capacity and heat generation. Therefore, the object of research was canvas fabric, which was fireproofed with an intumescent coating. Simulations were carried out and dependences were obtained, which allow to calculate the value of the heat flow at the boundary "pinocoke layer - fabric" depending on the effect of temperature. It has been proven that in the process of thermal impact on the fabric, the process of transfer of high temperature and its ignition takes place. On the basis of the obtained results of field tests to determine the process of transferring high temperature of the flame through the coating, it was established that when the flame acts on untreated model samples of tent elements made of canvas fabric, it ignites at 45 C and the flame spreads over the surface, which leads to complete combustion for 108 s. The pattern of burning for a model sample of tent elements, which is treated with a fire-resistant intumescent coating, showed the absence of flame propagation after the fire burned out, and the swelling of the protective coating was recorded, reaching 7...8 mm. The practical value lies in the fact that the obtained results of determining the properties of canvas fabric fire-resistant with an intumescent coating make it possible to establish the conditions of operation of products and building structures based on it.
