|Abstract:||In the coating processes, the formation of bubbles and microbubbles is relatively frequent inside the coating layer. Such bubbles,
which are formed as a consequence of air retention, are difficult to remove and specifically in high-speed (quick-drying) industrial application
where they cause permanent imperfections in the homogeneity of the layer.
High-intensity air-borne ultrasound may represent a clean means to improve homogenization by quickly breaking the bubbles just
when they are formed inside the coating film.
This paper deals with the direct application of air-borne high-intensity ultrasonic radiation at a frequency of about 21 kHz over coating
layers just immediately they have been deposited over wood substrates. Such novel process has been implemented and experimentally
studied at laboratory and semi-industrial stages.|
