Method for determining droplet size distribution during spraying and method of sorting based on it in paint development

摘要

The present invention relates toAt least including steps (1) to (3);A method of determining the droplet size distribution and / or uniformity of the spray in the spray formed during spraying of the coating material composition;EspeciallyAtomizing the coating material composition by atomizerCreate a sprayStep (1) and2. Optical trapping of droplets of droplets formed by traverse optical measurements and(3) including at least one characteristic variable of the droplet size distribution in the spray and / or the uniformity of the spray based on the optical data obtained in accordance with the processMethodAndIt is performed on the basis of the method described above when developing a paint compoundThe present invention relates to a method of compiling an electronic database and selecting a coating material composition.
