This invention belongs to the field of scintillator material preparation technology, specifically relating to a method for purifying high-purity cesium iodide and its application in the preparation of cesium iodide scintillator screens. The method involves sequentially mixing and heating cesium iodide-containing waste and residual materials to dissolve them, filtering and removing impurities, adsorption and removing impurities, concentrating and temperature-controlled crystallization, centrifuging, drying, and vacuum packaging. This process comprehensively removes solid particulate impurities, elemental iodine, and various trace metal ions from the raw materials, effectively preventing oxidation and deterioration during purification. The method is simple to operate, highly industrially feasible, and can purify waste materials to a high purity level that meets the requirements of high-performance applications. It allows for the reuse of waste materials at the same purity level, reducing production costs, alleviating raw material supply pressure, and complying with environmental protection requirements. Applying the high-purity cesium iodide obtained by this method to the preparation of cesium iodide scintillator screens using a vacuum thermal evaporation process ensures the excellent performance of the scintillator screens, making them suitable for high-end fields such as medical imaging and non-destructive testing.

The water-based stripping solution comprises a coupling agent, pure water, a polarity enhancer, an alcohol ether compound, an amine compound and a corrosion inhibitor. The water-based stripping solution provided by the application effectively reduces the volatilization of the polarity enhancer, the alcohol ether compound, the amine compound and the pure water by adding the coupling agent in the system, reduces the operation risk in the process, enhances the stability of the water-based stripping solution, maintains the original stripping effect, and increases the service life of the water-based stripping solution. After ensuring the stripping effect of the water-based stripping solution, the use amount of the water-based stripping solution in the photoresist removal process is reduced, the sewage discharge amount is also reduced, and the manufacturing cost and the sewage treatment cost are reduced in the whole.

The application belongs to the field of preparation of carbon nanotubes with special structure, and relates to a high-conductivity carbon-coated single-walled carbon nanotube carbon net, a preparation method and application. The method uses plasma arc discharge to prepare single-walled carbon nanotubes, uses in-situ arc discharge or high-temperature chemical vapor deposition to form a high-crystallinity carbon layer on the surface of the single-walled carbon nanotubes after treating a gaseous carbon source, and obtains a high-conductivity carbon-coated single-walled carbon nanotube carbon net with a macroscopic filamentous structure. The method can increase the purity of the product by more than 2 times and the yield by more than 3 times. Meanwhile, the high-crystallinity carbon coated on the surface of the carbon nanotubes can effectively improve the conductivity and dispersibility of the product, and the powder conductivity can reach 1.3*10 4 S·m ‑1 This method greatly saves the production cost, reduces the acid consumption for purifying unit mass of product, reduces the environmental pollution caused by waste acid, and has important application value in conductive paste and the like due to the high conductivity and good dispersibility of the product.
