Method and production line for rapidly preparing aerogel through radio frequency radiation

Abstract

The invention relates to method and production line for rapidly preparing aerogel through radio frequency radiation. The aerogel production line comprises a main machine for rapidly preparing the aerogel through radio frequency radiation, an original auxiliary material system, an inert gas system, a heat supply system, a recovery system and a three-waste treatment system. The main machine for rapidly preparing the aerogel through radio frequency radiation comprises a sol-gel station, an ageing station, a replacement modification station and a drying station. The main machine is provided with a radio frequency generator, a monitoring device and an automatic control device. The main machine is provided with an inner container which is through front and back, a crawler is arranged in the inner container and used for material conveying, a channel is formed in the inner container and can be communicated with or disconnected from other systems outside the main machine. Multiple forms of products such as aerogel powder, aerogel particles, aerogel felt, aerogel plates, aerogel cloth and aerogel films can be continuously produced, the extremely high production efficiency and automation degree are achieved, the aerogel industry is powerfully promoted to achieve production automation, large scale and intelligence.

Description

technical field [0001] The invention relates to an airgel preparation method and a production line, in particular to a radio frequency radiation rapid preparation airgel method and a production line. Background technique [0002] Airgel is a new type of nanoporous material. Due to its unique properties such as ultra-low thermal conductivity, low density, low dielectric constant, low refractive index, high specific surface area, high insulation, and high light transmission, it is widely used in thermal, The fields of optics, electricity, chemistry, and acoustics have shown many miraculous properties, and are known as miraculous materials that change the world. [0003] The current production technology of airgel mainly includes supercritical drying production technology and normal pressure drying production technology. Although after more than 10 years of development, the production process has been continuously improved and perfected, and the production efficiency has been c...

Problems solved by technology

[0004] The intermittent semi-automatic production method not only hinders the improvement of production efficiency, but also is not conducive to the control of product quality and labor cost due to the many links between the workshops and the number of on-site operators. During the production process, it is easy to cause misoperation by personnel or leakage of organic substances such as ethanol. Safety accidents caused by equipment failures or equipment failures pose a threat to the safety of on-site personnel
