CsxWO3 may be applied for preparing thermal insulation dispersion liquid. What should be noted is that the CsxWO3 powder used is nanopowder - CsxWO3 nanopowder modified by suitable interface. And the obtained dispersion is a new type of heat insulating nano dispersion. As you may know, before introducing the interface modification technology concept, we usually use a three-roll mill, disperser, bead mill, agitator mill and other dispersive grinding equipment to disperse and grind the material to the micron or sub-micron level. However, these devices are difficult to grind the powder into nanopowder. Why?
Since the particle size of the material is dispersed and ground by mechanical materials, the specific surface area of the powder increases sharply, the van der Waals force effect and the Brownian motion are more obvious, so the powder is easily reaggregated. And at this time, no matter how the grinding is done, the particle size is difficult to reduce.
In order to solve this problem, experts have found a very effective method - chemical mechanical process. The method is mainly to prepare a good interface modifier, and use a high-speed stirring bead mill as a tool to modify the nanopowder to avoid re-agglomeration, and then disperse the grinding until the particle size reaches the requirement. In other words, to apply CsxWO3 powder to the heat insulating nano dispersion, the cesium tungsten bronze powder needs to be appropriately modified by the interface and dispersed to the nano particle size.
