In parallel, requirements are growing due to ever stricter regulatory specifications. In addition to cleaning and drying processes designed to meet specific requirements and suitable technology, the software and the cleaning environment must also be adapted accordingly.

Reduction of air bubbles in spray-applied coatings / Matthew S. Gebhard in JOURNAL OF COATINGS TECHNOLOGY (JCT), Vol. 66, N° 830 (03/1994)

Langues : Américain (ame) Tags : Peinturage  Pulvérisation  'Bulle  air'  'Peinture  eau'  Défaut  'Etude  expérimentale'  'Photographie  rapide'  'Technique  vidéo' Index. décimale : 667.9 Revêtements et enduits Résumé : Microfoam (i.e., tiny (10 μm) air bubbles) in spray-applied coatings is a frequently encountered problem which may be aggravated in water-based coatings. This paper describes recent work to understand the dynamics of the microfoam formation and dissipation process. The data indicate that the majority of microfoam does not form by the splashing of atomized drops on the building liquid film. In fact, the atomized drops arrive at the substrate with numerous air bubbles, and poor atomization is observed to be a key to the problem. It is found that air bubbles dissipate through a dissolution mechanism and not the generally accepted rise and rupture mechanism. The dissolution is driven by surface tension and is mediated by diffusion through the liquid. The experimental data are found to agree with the Epstein and Plesset model, with lower diffusion coefficients, lower air solubility, and lower surface tension reducing the dissolution rate. This study has led to a novel solution to the problem and involves using carbon dioxide (CO2) as the driving gas instead of air. It is found that this leads to a significant reduction in entrapped air in conventional, high volume low pressure (HVLP), and air-assisted airless spray techniques. This approach is found to work because of the much higher solubility of CO2 in water versus air in water.

Surface functionalization of polymer nanofibers by ITO sputter coating / Qufu Wei in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 7, N° 4 (07/2010)

Atomic force microscopy (AFM) was employed to study the morphology of the nanofibers, respectively. The AFM results indicated a significant change in the morphology of the nanofibers before and after the ITO sputter coatings. The light transmittance and surface conductivity of the ITO-deposited nanofibers were also investigated. It was found that the surface resistivity of the PA6 nanofiber with the ITO deposition had a significant drop and the ITO deposition obviously affected the light transmittance of the PA6 nanofibers.
