Description

Technical Field

[0001] The utility model belongs to the technical field of aerogel drying, and specifically relates to a rice husk-based silica aerogel normal pressure drying device. Background Art

[0002] Silica aerogel is a nanoporous material whose network pores are filled with gaseous dispersion medium. It is precisely because of this special structure that it has unique properties, such as high porosity, large specific surface area, low density, small refractive index, low sound propagation speed, good insulation performance, low dielectric constant, etc. Therefore, it can be used as a thermal insulator, adsorbent, drying medium, catalyst carrier, etc., and has a wide range of application prospects. The nanoporous structure of aerogel effectively reduces the solid-state heat conduction of the material, and the nanopores can inhibit the effect of gas molecules on heat conduction. This silica aerogel and its composite material based on it have very low thermal conductivity and is a new type of thermal insulation material. However, the raw materials and supercritical equipment of silica aerogel are relatively expensive, which limits its application and large-scale production. The preparation of silica aerogel at home and abroad generally adopts the sol-gel method, which is to mix the silicon source with an appropriate amount of solvent, and under the action of water and a catalyst, use the acid-base two-step method or the one-step method to synthesize the wet gel, and then use supercritical drying technology or atmospheric pressure drying technology to prepare it. The silicon source generally uses ethyl orthosilicate, water glass, rice husk ash, etc.
