Analysis of the application of aerogel products in fire resistant components
As the country accelerates the"dual carbon"strategy and low-carbon transformation in the construction field,aerogel materials with extremely low thermal conductivity develop rap-idly.With the development of aerogel preparation technology,aerogel products began to appear and be applied.In order to study the fire resistance of aerogel products and explore their applicabil-ity in fire resistant building components,two fire resistant build-ing components,aerogel composite fire resistant glass and aero-gel expanded perlite door,were selected to test the fire resistance and other items according to the standard requirements.The re-sults show,aerogel composite fire resistant glass has excellent heat resistance,cold resistance and ultraviolet radiation resis-tance.Under high temperature conditions,it can maintain fire in-tegrity within 90 minutes,and lose fire resistance and heat insula-tion after 85 minutes.Aerogel expanded perlite smoke toxicity and combustion performance are in line with the requirements of GB 12955-2008,Fire Doors,and the doors can maintain fire in-sulation within 90 minutes.
