Title of the articleAnalysis of fracture flue brick industrial pipes
Abstract.Problem statement. The aim of this research work was to determine the causes of the destruction of the brick flue industrial pipes after repair of one of the organizations of Kazan in Tatarstan. Results. In the operation of the repaired pipe of these facilities in the winter-spring period, there have been significant damage in the walls from the outside. Experience of working on the evaluation of materials and structures [1, 2, 3] allowed to assume that one of the causes of these defects could be insufficient water vapor permeability also organic compositions. Another reason may be the application of paint to wet, not previously drained surface of the wall. Mode industrial chimneys do not preclude the occurrence of condensation, and the temperature difference between inside and outside of the pipe promotes mass transfer of moisture in a direction toward the outer wall surface. Conclusions. The results of this test, at sites close to the outer surface of the water vapor is condensed and crystallized at low temperatures, which leads to the destruction of the brickwork.
Keywords.organosilicate composition, vapor permeability, resistance to water vapor transmission, adhesion, cohesion.
