| Résumé : |
Recent advances in pigmentation technology have allowed formulators to achieve a greater infrared reflectivity in functional coatings compared to traditional pigmentation technologies. The technology also maintains the appropriate light absorption in the visible spectrum, to impart colour.
The ability of functional infrared reflective coating systems to lower heat build-up results in reduced thermal warpage, reduced thermal cycling degradation, lower energy costs related to cooling and improved comfort and functionality of dark colour exterior objects such as park benches, hand railings and even polymer concrete.This paper will explore advances in infrared pigmentation technology to the reader, and explore potential new applications of infrared reflective pigmentation technology in composites.
Rising energy costs continue to drive advances in new technologies designed to improve energy efficiency. One such technology is the use of specialty infrared reflective pigments used to impart colour to an object and reflect the invisible heat from the object to minimise heat build-up, when exposed to solar irradiance. Ultimately, the reflection of infrared energy lowers the heat build-up resulting in a reduction on the load of the cooling system and therefore achieving cost savings.
In order to understand and maximise the functional mechanisms and effects of infrared reflecting pigmentation technologies, one musts understand the sciences regarding solar radiation, black and gray body radiation, emissivity, reflectance, total solar reflectance, light scattering, light absorption, and relevant test methods. |
