Résumé : |
The time-shift process makes it possible to measure the size of droplets of atomised waterborne paint in specific locations and gives a new insight into atomiser designs and parameters. |
Note de contenu : |
- Measuring transparent and non-transparent droplets
- Analysis of four waterborne base coats
- Bell serration influences the droplet size in specific locations
- A better understanding of atomisation processes
- Fig. 1 : The measurement device allows the atomisation process for paints to be investigated in detail
- Fig. 2 : Diagram of the size measurement of paint droplets using SpraySpy and measurement of a paint's spray during high-speed rotary atomising
- Fig. 3 : Transmission measurements for dry coatings of paints M1 to M4 with a thickness of 10 µm. NT (%) = proportion of non-transparent droplets from the SpraySpy measurements
- Fig. 4 : Correlation between the droplet diameter (D) and the droplet speed at different atomiser speeds for paints M1 to M4
- Fig. 5 : Influence of bell serration on the droplet speeds at specific locations for a selected waterborne paint |
