Tungsten Oxide

Adipic acid is mainly used for nylon 66 engineering plastics and raw materials, and in the production of various ester products. Adipic acid is also used for polyurethane elastomer material, acidifier various foods and beverages, sometimes its better than citric acid and tartaric acid. Adipic acid has many functions and a huge demand, but it is a big polluter. The industrial process mainly uses nitric acid to oxidize cyclohexanol and cyclohexanone (KA oil). The method has high yield, but nitric acid seriously damages the equipment and produces a large amount of nitrogen oxides which pollute the environment seriously. With the improvement of human environmental protection consciousness, people urgently need to find environmental protection and pollution-free solutions to solve the problem of adipic acid production. In recent years, Cao Fabin, a scholar, has proposed that adipic acid is used as catalyst to synthesize adipic acid, according to previous experience, he uses tun

There are many inhibitors of scheelite flotation, but the most popular and widely used is sodium silicate , which is recognized by industry as the most effective and cost effective inhibitor. Sodium silicate , commonly known as water glass , the molecular formula Na 2 SiO 3  is a water-soluble silicate, is a kind of mineral binder, non-sulfide ore, especially a typical inhibitor of silicate minerals. Sodium silicate is selected in the floating scheelite and playing two main functions: one is to make the silica gel modified by physical adsorption on mineral surface, two is the adsorption of SiO 3 2- , HSiO 3 - , OH -  and H +  on the surface of quartz and silicate minerals, which increases the electronegativity and hydrophilicity of the mineral surface. In scheelite flotation process, sodium silicate was inhibited in quartz, calcite and silicate, generally speaking, sodium silicate is selective when used in low dosage, but using too much will lose the selectivity. There

Cesium tungsten bronze (Cs x WO 3 ) is synthesized by solid phase method or liquid phase method with cesium carbonate and sodium tungstate as raw materials. Therefore, cesium tungsten bronze is also called cesium tungstate. Cesium tungsten bronze Cs x WO 3  has the function of oxygen compounds in eight face special structure, with low resistivity and low temperature superconducting propertiesaterials. It mainly used to make high-temperature insulation coating, building glass, Low-E glass, automobile insulation film, plant planting shed, LCD screen and so on. Synthetic of cesium tungsten bronze can be obtained by solid phase method and liquid phase method. In the earlier period, most of cesium tungsten bronze was prepared by solid phase synthesis, such as vapor phase reduction and hydrogen reduction, but the synthesis of solid phase is difficult and the cost is too high. Therefore, with the increasing attention of cesium tungsten bronze, more and more scholars began to study t

Cesium tungsten bronze (Cs x WO 3 ) is a kind of tungstate powder synthesized by solid phase method or liquid phase method with cesium carbonate and sodium tungstate as raw materials. Cesium tungsten bronze is also called cesium tungstate.  As everyone knows, the sun's heat is mainly concentrated in the two part of the visible light and near infrared light, cesium tungsten bronze Cs x WO 3  particles can ensure good visible light transmittance, and can cover most of the near infrared caused by heat, and cesium tungsten bronze is an ideal material for manufacturing automotive insulation film. However, in the manufacture of cesium tungsten bronze Cs x WO 3  heat insulation film, it is found that Cs x WO 3  particles are difficult to disperse in solution, and attached to the heat insulation film. In order to realize the near infrared shielding function of cesium tungsten bronze Cs x WO 3  particles, the dispersion and stability of particles in slurry must be improved, partic
