Metallpulver som Pigment foer Laegemissiv Faerg (Metallic Powder for Low Emissive Paint).

摘要

A study of the use of metallic powder for use in binder in order to reduce the emittance of painted surfaces has been carried out with respect to the optical properties. Powders of silver, copper and iron had their surfaces modified by an oxidation process. The oxidized surfaces showed low metallic gloss in the visible region and a reflectance level in the infrared which indicates low emissive properties. This study indicates that it is possible to produce a low emissive paint without an increase of the metallic gloss. The work has not focused on optimization of the process parameters. Consequently, a systematic study of the influence of the oxidation time and powder particle size on the optical properties can result in an improved wavelength selectivity with respect to the optical properties.
