ABSTRACT
Silica aerogel composites have promising applications in high-temperature heat storage insulation. However, the impact of high temperatures and moisture on their insulation performance remains unclear. To reveal influences temperature absorption property transfer silica composites, an experimental numerical study was conducted to explore micromorphology, thermophysical parameters, characteristics, response. The service limit composite has been clarified. Measurements for thermal conductivity, specific capacity, diffusivity, surface area, density, porosity, pore size distribution heated (at a 600, 800, 1000, 1100, 1200°C). characteristic curve at 20°C obtained. Thermal testing under varying heating content completed. Additionally, method developed calculate moist composites. with depends game between conductivity latent heat. Compared negative effect performance, positive influence evaporation is dominant situations involving higher than phase transition temperature.
