Description
Summary:The complex approach to estimation of efficiency of application of intumescent coating for wood, the peculiarity of which is investigation of flame retardant efficiency of a covering, installation of firehazardous properties and research of operational characteristics, is offered. The solution of this problem is carried out according to standard methods. It is revealed that for rough wood there is a rapid process of combustion of material and the release of a significant amount of heat, for fire-proof wood the temperature is lower than the temperature of ignition of wood. In order to establish fire protection efficiency in the application of coatings, studies have been carried out on determining the group of wood burning in terms of mass loss and increase in temperature of flue gases, and it was established that when the coating is treated, the wood passes into a group of heavy materials. Experimental studies have established that after placing a sample of wood in the test chamber, its ignition begins with the release of a significant temperature and the spread of the flame on the surface; instead, for a sample of fire-retarded wood there is a gradual decrease in temperature, that is, the work of the coating is fixed, and accordingly, the decrease in the smokeforming ability of the wood is flame retardant coating . It has been established that as a result of surface treatment with intuessent coating, products lose the ability to moisten and absorb water, which provides them with resistance to atmospheric factors and reduces the permeability of corrosion-resistant corrosion resistant sponge components several times.
