Nano Cs0.33WO3 is a type of infrared ultraviolet shielding material, which means that it can shield ultraviolet rays and near-infrared rays. It can be prepared by hydrothermal synthesis using Cs2CO3 and Na2WO4 as raw materials, and citric acid as a reducing agent. Preparation of Cs0.33WO3 Coating The Cs0.33WO3 particles were dispersed in an aqueous solution to obtain Cs0.33WO3 dispersion slurry, and 2.5% polyethylene glycol-400 was added as a wetting agent, and then 1mm zirconia balls were used for ball milling.…

Nano Cs0.33WO3 is a type of transparent thermal insulation material. As a kind of heat insulation means, the transparent thermal insulation material is of social and economic importance for industrial and civil use. Preparation of Nano Cs0.33WO3 by Liquid Phase Method The liquid phase method is the most widely used method for preparing nano materials. There are many liquid phase methods, such as chemical coprecipitation method, sol-gel method, hydrothermal method, and solvothermal methods, etc. Among them, hydrothermal and solvothermal methods…

Nano cesium tungsten bronze is a kind of infrared ultraviolet shielding material. As its name implies, it is a type of heat insulating material that can shield near-infrared rays and ultraviolet rays with good visible light transmittance. This type of heat shielding material is a good choice for building glass and auto glass. Visible light transmittance refers to the light outside enters the room. The higher the visible light transmittance is, the brighter the room is. The transparent aqueous dispersion…

Nano cesium tungsten bronze is a kind of transparent thermal insulation material, which can shield ultraviolet rays (UV) and near-infrared rays, and has good transmittance of visible light. Nano cesium tungsten bronze may be prepared by vapor phase method. Vapor phase method means that using gas as reaction raw material to perform chemical reaction or physical reaction, and the nano films or nano particles are obtained. The commonly used vapor phase methods are mainly divided into chemical vapor deposition method…

Nano cesium tungsten oxide may be used for the preparation of ceramic microsphere (dingal color master). It is a promising ceramic coloring method to use this type of ceramic color master to produce ceramic products. The advantages of nano cesium tungsten oxide ceramic microsphere: 1. Good dispersion in the ceramic products; 2. With bright color; 3. No color difference on the surface of ceramic products; 4. Convenient to exchange colors; 5. Lower cost than other pigments in the long run;…

Nano cesium tungsten oxide may be used to prepare nano-ceramic color master. Thus, this type of color master has a lot of advantages as follows: 1. With extremely high gloss and coloring power; 2. May maintain the chemical stability of pigments and other additives; 3. Uniformly dispersed in the ceramic products; 4. Easy to operate; 5. Protect environment from polluting; 6. With nice light resistance, it is suitable for outdoor applications. A Method for Preparing Nano Cesium Tungsten Oxide Use…

Nano cesium tungsten oxide (Cs0.33WO3) has excellent near-infrared shielding performance so that it can be used to produce nano-ceramic dispersion solution. Dispersion solution is a form of dingal nano coating. Near-infrared light is the main carrier of heat in sunlight. The higher the near-infrared shielding rate is, the better the heat insulation effect is. Are Cs0.33WO3 particles easy to disperse in solution? And what are important? The Cs0.33WO3 particles are difficult to disperse in solution, so, the dispersity and stability…

Nano cesium tungsten oxide is a type of transparent near-infrared shielding material that can shield most of the near-infrared rays and ultraviolet rays. In other words, cesium tungsten oxide nanopowder can block some of “heat” in hot summer and can guarantee high visible light transmittance so that it has potential applications for thermal insulation coating in architectural glass and auto glass. Preparation of Nano Cesium Tungsten Oxide by Solid Phase Method The preparation principle of this method is to burn…

Nano cesium tungsten oxide may be used as a thermal insulation film in heat insulating window glass. So, the window glass will has the following advantages: 1. Anti-glare, so that drivers have a clear vision, to ensure the safety of driving; 2. Shield 90% of the UV, to prevent in-car items such as plastic parts and rubber parts from fading and even aging; 3. Protect people from secondary damage of broken glasses. Nano cesium tungsten oxide heat insulating film used…
