A decrease in the diameter of a droplet of a protective coating stream occurs in cases of a decrease in the diameter of the nozzle, an increase in the volumetric flow rate and the lower surface tension coefficient. To study the effect of droplet sizes on the quality of the protective coating, the conditions for obtaining droplets of different diameters were determined. During the experiment, it was found that the most significant parameters were those of the nozzle and the operating pressure of the installation. The change of these parameters caused the change of the size of the material droplets. To do this, replaceable nozzles with various diameters were installed and the supply pressure was also regulated.
