The utility model discloses a multifunctional vertical face spraying device, which belongs to the technical field of spraying and comprises a spraying panel and a clamping mechanism. The spraying panel is provided with a first horizontal sliding groove and a second horizontal sliding groove which are parallel. The clamping mechanism is provided with a first clamping plate and a second clamping plate which are perpendicular to the first horizontal sliding groove and the second horizontal sliding groove. The clamping plates can keep the included angle between the clamping plates and the first horizontal sliding groove and the included angle between the clamping plates and the second horizontal sliding groove unchanged. A linkage structure is arranged between the first clamping plate and the second clamping plate, so that a spraying worker moves the first clamping plate or the second clamping plate with a single hand, the first clamping plate and the second clamping plate can clamp or release a to-be-sprayed assembly, and one hand can be liberated for positioning the to-be-sprayed assembly; and therefore, one spraying worker can position and clamp the to-be-sprayed assembly, the working efficiency is greatly improved, and the labor cost is reduced.

The application belongs to the technical field of battery separators, and particularly relates to a battery separator and a preparation method thereof. The battery separator comprises a separator base material and a support layer, wherein the support layer comprises at least nanocellulose and hexagonal flake magnesium hydroxide, and the mass ratio of the nanocellulose and the hexagonal flake magnesium hydroxide is 1-10:20-100. The hexagonal flake morphology of the magnesium hydroxide is easy to stack to form a flake layer structure on the surface of the base material, thereby supporting the base material. The fiber skeleton structure of the nanocellulose plays a connecting role, and keeps the interface stability of the coating while avoiding the risk of coating cracking and peeling caused by excessive rigidity of the coating.

The application belongs to the technical field of wafer processing, and discloses a polishing method of a cadmium zinc telluride wafer. The method comprises the following steps: cutting a crystal bar into a wafer; etching a single crystal area on a 111B surface of the cut wafer, and recording the position of the single crystal area; rough polishing the 111B surface and a 111A surface of the etched wafer; first fine polishing the 111B surface of the rough polished wafer; using a wafer scriber to cut out the single crystal area of the first fine polished wafer according to the recorded position of the single crystal area; second fine polishing the 111B surface of the single crystal area of the wafer; and cleaning. The polishing method is simple in process and convenient to operate, and the edge collapse and TTV problems of the prepared cadmium zinc telluride wafer are obviously improved.
