Description

Technical Field

[0001] The invention relates to the technical field of silicon dioxide aerogel powders, and in particular to a silicon dioxide aerogel powder mixing device and a use method thereof. Background Art

[0002] Silica aerogel powder is a new type of nanoporous material. Its surface area can usually reach hundreds of square meters per gram, or even higher, which makes it have a strong adsorption capacity and can adsorb a large amount of gas, liquid molecules, etc. The porosity can be as high as 90% or more. The pore size distribution is uniform, and most of them are nanoscale pores, which makes it have extremely low density and good thermal insulation performance. The density can be as low as tens of kilograms per cubic meter. It is one of the lightest solid materials in the world. Its light weight makes it have important application value in aerospace and other fields. The thermal conductivity at room temperature can be as low as 0.013W / (m·k), or even lower, which is much lower than the thermal conductivity of air. Therefore, it has excellent thermal insulation and heat preservation performance, which can effectively prevent the transfer of heat. There are a large number of tiny interconnected pores inside. When sound waves enter its interior, friction will continue to occur in the pores, thereby consuming the sound wave energy and achieving the effect of sound insulation and noise reduction. When mixing operations are required when using silica aerogel powder, mixing equipment is required. Therefore, we need a silica aerogel powder mixing device and a method for using it.

[0003] However, the currently used silica aerogel powder mixing device and its use method cannot perform quantitative feeding during operation, and cannot improve the efficiency of stirring and mixing the silica aerogel powder. At the same time, the feeding rate cannot be controlled and adjusted. There is no certain storage space for the silica aerogel powder mixture, and the inner wall of the device cannot be quickly cleaned. Summary of the invention
