This paper describes the technology and properties of pre-anodized aluminium, a material ideally suited to aiding energy conservation in lighting and other applications. Reflectors are a natural application for aluminium as it has the highest reflectivity of all metals commercially available at economic cost. SUMMARY. Electro-chemical conversion of aluminium to its oxide during anodizing grows a protective layer which is transparent and intimately linked on an atomic scale to the metal itself. This gives the advantage that there are no problems with de-lamination, undercutting or peeling of the coating. The optical properties of pre-anodized Aluminium depend partly on the characteristics of the metal from which it is made and partly on the optical behaviour of the coating. The oxide film grown in anodizing is transparent and has a refractive index of approximately 1.6. Hence light falling on the surface will penetrate the surface of the oxide and be refracted in towards the aluminium surface. It therefore passes twice through the thickness of the clear anodic film during reflection and film purity and properties are very important. Control of these is critical for top quality material and, working with their suppliers, The Buchholz Group have developed ways of maximising spectacular refectance to allow optimum light control. Since it is produced in flat sheet, the optical properties of Anofol material can be measured accurately by a number of instruments to characterise light output from the surface...Ver documento.
