Abstract

Abstract: Blanket insulators which can reduce heat transfer through reduction of solid conduction, gas convection and radiation, would be the most appropriate insulation materials. Due to the importance of insulating issues, especially in terms of energy saving, properties improvement of this blanket is considered. To improve the thermal properties of the insulation blankets, aerogel as a super insulator material that has a nano metric structure, low density and high specific surface area demonstrated exceptional properties added to blanket. As a result of this work, the thermal properties of polyester mat blanket insulator were improved by embedding in sol of aerogel materials. The thermal diffusivity (α) and thermal conductivity (K) are obtained 2.45×10 -7 (m 2 /s) and 0.04238 (W/m.K) for aerogel blanket insulator, and these coefficients for the polyester mat blanket are 9.26×10 -7 (m 2 /s) and 0.0676 (W/m.K).
