Graphite powder can be fed into a high-temperature furnace through an inlet and an outlet, then the high-temperature furnace and a heating piece are operated, the high-temperature furnace heats graphite in the high-temperature furnace, meanwhile, the heating piece heats a connecting rod and an arc-shaped piece, and part of the graphite is attached to the bottom of the high-temperature furnace; the high-temperature furnace can directly transfer heat to the part of graphite, the part of graphite can make contact with the arc-shaped piece, so that the part of graphite can be subjected to double-face heating, and during heating, the rotating driving assembly can be operated to drive the multiple sets of internal heating assemblies to rotate through the first rotating shaft; the other part of graphite falls into the upper portion of the arc-shaped piece in the rotating process of the internal heating assembly, the graphite material of the part can be heated through the connecting rod and the upper portion of the arc-shaped piece, and when the scraper moves, graphite powder attached to the lower surface of the interior of the high-temperature furnace can be scraped and moved, so that the high-temperature furnace does not heat the same batch of graphite materials all the time.

This invention discloses a cefoperazone sodium and sulbactam sodium composition and its preparation method, comprising the following steps: preparing a chitosan-β-glycerophosphate sodium colloidal solution; mixing dry ice and sorbitol evenly, then adding the mixture to the colloidal solution, freezing, heating, and drying under reduced pressure to obtain chitosan-β-glycerophosphate sodium nanospheres; slowly adding cefoperazone sodium, sulbactam sodium, and chitosan-β-glycerophosphate sodium nanospheres to water for injection, stirring to dissolve; adjusting the pH to 7.1-7.5, adding an adsorbent for adsorption and filtration, adding dry ice; freeze-drying to obtain a cefoperazone sodium and sulbactam sodium mixed powder. The nanospheres of this invention, with a certain size gradient, are beneficial for the uniformity of the mixed powder of cefoperazone sodium and sulbactam sodium, resulting in a longer-lasting efficacy, better stability, lower hygroscopicity, and also playing an antibacterial role.

The invention belongs to the technical field of superconducting material processing, and discloses an NbTi film for a superconducting coaxial cable and a preparation method of the NbTi film. NbTi superconducting powder, a dispersing agent, a binding agent and a solvent are subjected to ball milling and mixing to obtain slurry, the dispersing agent is phosphate, the binding agent is polyvinyl butyral, the solvent is butyl carbitol, the NbTi superconducting powder can be evenly dispersed in the slurry through the auxiliaries, and then the high-uniformity NbTi thin film is obtained through coating, drying and sintering. According to the low-temperature stepped drying scheme and the rapid thermal annealing sintering scheme, decomposition and volatilization of the auxiliaries can be promoted, NbTi particles are sintered to form a continuous network structure, and the NbTi thin film with the excellent superconducting performance is formed. The NbTi film preparation method provided by the invention is controllable in Nb / Ti design ratio, low in process cost and high in finished product uniformity, and has a wide application prospect in NbTi films for superconducting coaxial cables.

According to the anti-sticking coating for sintering, TiN or TiC serves as an anti-sticking and blocking material, MgO serves as a shell forming agent, MgO and a TiO2 oxide film formed on the surface of the TiN or TiC form a magnesium titanate (MgTiO3) ceramic phase through a solid-solid diffusion reaction, the magnesium titanate ceramic phase is connected with coarse TiN or TiC particles after high-temperature sintering, and the anti-sticking coating for sintering is obtained. A relatively hard TiN or TiC shell is formed, so that the friction resistance and scratch resistance of the coating are improved, and the service life of the coating is prolonged. According to the sintering tray coated with the anti-sticking coating for sintering, the surface of the coating is free of peeling, cracking and other defects after sintering, the coating is completely reserved, the good and stable barrier effect is achieved, and the problems that impurities are likely to be introduced into an existing sintering anti-sticking coating, the sintering anti-sticking coating reacts with sintered alloy at the high temperature, and the performance of a sinter is deteriorated are solved.
