Vacuum aluminum plating of aluminum powder prepared by the technology research

Abstract: At present aluminium powder is widely used in industrial coatings,automobile coatings, printing ink and chemical industry, etc. Its demand for more and more big, the domestic production of aluminum powder method is more, this article will focus on the study on preparation of vacuum aluminum plating aluminium, and proceeds to the vacuum plating aluminum film stripping technology exploration, can effectively will vacuum plating of nano aluminum particles membrane stripping method, obtain nanometer aluminum powder. Through soaking peel test implementation of a variety of organic solvents, compared the different organic solvents in the detachment, to the difficulty of the obtained with tetrahydrofuran as the main body of the organic solvent system to deal with the vacuum aluminum plating film, to achieve the success of aluminum film on aluminum particles, at the same time through the centrifugal technology to deal with the solution obtained separation, implements the powder recovery of aluminum particles.
