Study on Thermal Insulation Performance of Silica Aerogel Thermal Insulation Blankets. [PDF]

Gels
In this paper, the thermal insulation performance of silica aerogel was studied. Aerogel heat insulation blankets can be widely used in the military, cold storage, aerospace, automotive and other industries. The heat insulation principle of aerogel was analyzed theoretically, and the heat transfer model of aerogel was established.
