[Abstract]:The principle, characteristics, application and progress of supercritical fluid technology in the field of surface finishing are reviewed. The cleaning of silicon wafers by supercritical CO_2, supercritical extraction and purification of electroplating and chemical intermediates are emphasized. Nanocrystalline particles prepared by supercritical fluid, electrodeposition and chemical deposition of supercritical fluid, supercritical water oxidation technology is used in the treatment of various refractory organic wastewater, industrial sludge, waste printed circuit board and so on. And the development of supercritical fluid treatment equipment. The facts show that supercritical fluid technology has a broad application prospect in the surface finishing industry, it is the ancient surface finishing industry to the technology more advanced, the technology is more environmentally friendly. A new way to improve the quality of coating.
