In addition to bell speed, paint flow rate is the second factor that affects the fineness of atomized particles. When other parameters remain constant, the lower the flow rate of the paint, the finer the atomized particles, but together they will also lead to an increase in the volatilization of solvents in the paint mist.
When the paint flow rate is too high and the bell cup is overloaded, the coating film at the edge of the bell cup is thickened to a certain extent, resulting in the groove pattern on the bell can not make the paint divert, and the layered patent leather appears, which will cause the undesirable phenomenon of bubbles or uneven size of paint droplets.
The paint flow rate of each spray gun of the spraying robot is related to the caliber of the high-speed bell and the density of the paint at the speed, and its upper limit is determined by the fineness of atomization and the effect of electrostatic coating. Practical experience dictates that the paint should be fed at a steady speed, and fluctuations in a small range will not affect the quality of the coating film.
In the actual spraying process, the spraying robot sprays different areas of each bell cup, and the flow rate of the paint is also different, and the paint flow rate of the bell is also changed due to the change of the shape of the coated object. Taking the spraying of the car body as an example, when spraying a large area such as the door panel, the amount of paint spit out should be large, and when spraying the door column and window column, the amount of paint spit out should be small, and the amount of paint spit out should be actively and accurately controlled in the spraying process, so as to ensure the uniformity of coating quality and coating film thickness, which is also one of the important measures to improve the utilization rate of coating.
