Purpose. Mathematical modeling of the interaction of aeroions with multi-fraction dust particles of fibrous carbon composites of undefined geometry, which include both matrix elements and carbon fiber fractures. Method. The modeling was carried out by deriving new predicted dependencies of the interaction of aeroions with dust elements, which is based on the application of aerodynamics, electrostatics and mass transfer equations, taking into account the peculiarities of the dust and fractional composition of the air space of the working environment, as well as the empirical method during the field experiment and analytical analysis of the obtained results. Results. The obtained results make it possible to evaluate the aeroionic composition of the air and the effect on the dust concentration of the artificial ionization of the air in the working area. Scientific novelty. The mathematical model took into account the peculiarities of dust formation during the processing of fibrous carbon composites, the geometric shape of the formed dust particles and the speed of interaction of individual dust components containing elements of the matrix and fibers of the composite material with aeroions of the air during artificial ionization of the working space. Practical value. The use of artificial ionization of the air in the working area allows you to accelerate the deposition of industrial dust, which is formed as a result of the mechanical processing of fibrous composite materials, which allows you to reduce the negative impact of carbon dust on the health of workers.Downloads
