Research of Aerodynamic Characteristics of Asbestos-Cement Dust in the Ventilation Emissions to the Atmosphere

摘要

The article describes the chemical properties of asbestos-cement dust and its effect on the human body. The main sources of dust emission at the enterprise for the production of asbestos-cement have been determined. Also in this research were determined the aerodynamic properties of particles of asbestos dust at the plant for the production of asbestos by method of fractional sedimentation. In the course of the experiment, the dispersion composition of dust was determined by the method of sedimentometry and analysis by means of a microscope and a PC. The dependence of the dust settling rate on the equivalent diameter of a particle in a probability-logarithmic grid is revealed.
