Effect of Applied Methods and Materials on the Quality Control of Printed Coatings on Anodized Aluminium | Chapter 10 | Research Highlights in Science and Technology Vol. 6

 This division presents studies on the processes, measurements and doing parameters in the publication of anodized aluminium. Research results on treatment and anodization of commercially pure aluminium (AA1050) are bestowed, the properties of the publication inks and aluminium surface are examined, the publication parameters and calculations involved in characterization of used coatings on the aluminium surface are determined. The inspection concerns the influence of mechanical pretreatment of clean aluminium by different types of abrasive belts and other anodizing limits (type of electrolyte, concentration, temperature, used voltage or current mass, etc.) on the printing value. In addition, the role and limits that determine the characteristic possessions of the printed coatings are discussed. Two types of publication techniques were secondhand, namely the sign-jet digital publication and the screen printing. The influence of different types of publication plates and printing inks, to a degree UV-curing inks or binding material resin-located ones, in addition to their interaction with aluminium surface in the publication process are investigated. Besides, the effect of the adding of nanoparticles, such as silicon dioxide (SiO2) and titanium dioxide (TiO2) to the willing inks on the colorimetric properties and developing stability of the coatings are conferred. The results presented in this study display that a suitable qualification of the aluminium surface and the printing limits results in an improvement of the support, quality, and the outdoor opposition of the printed coatings. The present study shows that optimum scene of all observed effective parameters is of extreme importance from an academic and a commercial viewpoint, especially when features such as attachment, weatherability, and resistance against chemical compound are required in modern applications, such as barcodes, branding, panels, etc.
