Study on the Key Technology of Intelligent Energy-Saving Building Glass by Nanometer Method

Abstract:

At present, doors and windows are still weak parts of building envelope structure in building energy-efficiency, and these energy-saving glasses applied currently do not have the intelligent adjustment function according to temperature, that is not conducive to building energy saving. In this paper, the key technologies to make energy saving glass with intelligent regulatory functions were studied: the preparation of nanopowder with regulatory insulation function and the dispersion of the nanopowder. The results show that: the long-term stable and uniform ATO dispersion can be batch produced by choosing a suitable dispersant, applying of rod mill combined with ultrasound process. Using industrial sulfuric acid oxygen vanadium, ammonium bicarbonate and sodium tungstate as raw material the nanometer VO2 synthesized can undergo phase change at room temperature. During the phase transition it has the obvious hot optical switching characteristics, and so it has the potential to achieve intelligent control functions of building glass.
