The invention discloses a dry-wet combination method to prepare superfine calcined kaolin. After grinding by dry method, the kaolin raw ore grains are classified according to the grain size. The superfine with the grain greater than 1250 meshes can be made into a finished product by direct calcination. While for the meal with the grain less than 1250 meshes, dispersing agent, intercalation agent,and whitening agent can be added simultaneously under wet grinding, so as to improve the grinding efficiency, shorten the grinding time, and reduce the energy consumption during grinding process, as well as improve the mixing effect of the whitening agent and the kaolin. The meal scattered and dried after grinding, is sent into rotary kiln for calcinations. The kaolin is grinded again after calcination by wet grinding method. The dispersing agent and modifying agent are added simultaneously, to combine the superfine grinding and the modifying of product simultaneously. The modified powder is grinded to obtain the other finished product after drying and scattering. The invention allows superfine calcined kaolin with different specification during the same production line by the control of the process condition, thus reducing the working procedure, improving the added value of product, broadening the application field and product performance, so as to meet the requirements of different customers.

The invention discloses a surface treatment device used for machining a Nixie tube. The device comprises a rack, a worktable arranged on the upper end of the rack and used for bearing machining of a workpiece, feeding mechanisms which are located on the upper end of the worktable, symmetrically arranged and used for conveying the workpiece, and cleaning mechanisms located on the upper ends of thefeeding mechanisms and used for removingworkpiece surface pollutants. The bottom end of a second air cylinder is movably connected with a telescopic rod, the bottom end of the telescopic rod is fixedly connected with a push plate through a bolt, the bottom end of the push plate is fixedly provided with a brush through a bolt, the brush can treat the pollutants on the workpiece surface, when the second air cylinder is started, the second air cylinder pushes the telescopic rod to move downwards, the push plate moves the brush downwards to the workpiece surface to carry out surface treatment on the workpiece, the pollutants on the surface of the workpiece can be removedthrough the brush, the surface cleanliness of the workpiece in the next machining procedure can be improved, and the machining quality is improved.

The invention belongs to the technical field of gear manufacturing, and in particular relates to a preparation process of anti-friction and wear-resistant gear parts, a method for preparing a high-pressure anti-friction and wear-resistant hydraulic pump by performing surface carburization and coating treatment through physical vapor deposition technology, and the carbide Combining the coating, PVD method and carburizing technology, a carburizing diffusion layer is prepared between the carbide coating and the workpiece substrate by ion sputtering, that is, the surface of the workpiece is first carburized by ion sputtering. , and then use ion plating and magnetron sputtering composite method to deposit VCrWSiC / Cr carbide coating with gradient composition to slow down the difference in physical properties between the coating and the substrate material, improve the hardness of the substrate material, and enhance the coating and substrate. Adhesion performance, thereby improving the comprehensive performance of gear parts such as anti-friction and wear resistance, effectively improving the surface treatment efficiency and the service life of the workpiece.
