Cs doped tungsten oxide powder may be applied for producing a new environmentally-friendly thermal insulation dispersion liquid. The obtained nano dispersion liquid may be made into nano-slurry, and then be prepared into transparent nano heat insulation coating. As you may have known, the coating is widely used for the heat insulation of architectural glass such as exhibition halls. According to experts, it is necessary to carry out high-speed dispersion treatment of the coating. In this regard, the experts introduced this:

The high-speed dispersion method has been widely used in the research and development of cesium doped tungsten oxide nano heat insulation coating. The high-speed dispersion method refers to a method that adds nano powder, solvent, dispersion liquid and other auxiliary agents to a high-speed disperser reaction vessel, and set a high stirring rotation speed to uniformly disperse the slurry under high-speed stirring. During the process of the particles moving up and down on the surface of the slurry, under the action of high shear force, the aggregated nano aggregates are dispersed into agglomerated particles with smaller particle size. Under the action of high-speed dispersion and high shear force for a long time, the nano aggregates and emulsions in the slurry are fully dispersed by solid-liquid, and be mutually blended. The surface of the nanoparticles is coated with a dispersing agent, and depolymerized to form smaller particles and then coated with a dispersing agent, so that the external surface of nanoparticles is surrounded by a dispersing agent. And therefore it will not agglomerate with each other. And the nano slurry is successful prepared.
