The invention discloses a wire hanging device suitable for unmanned aerial vehicle power pay-off, and relates to the technical field of unmanned aerial vehicle power pay-off, the wire hanging device comprises an unmanned aerial vehicle body and a support, and a pay-off assembly is arranged in the support. When the device is used, a first forward and reverse motor is started, a connecting rod and a long gear are driven to rotate, two toothed plates are driven to move relatively, a first wave clamp and a second wave clamp move relatively, two arc-shaped clamps move relatively, an electric wire is clamped, and double clamping and fixing of the electric wire are achieved. The wave-shaped characteristic of the first wave clamp and the second wave clamp can generate more contact points, the wave crests and the wave troughs can be tightly attached to the surface of the electric wire, the friction force to the electric wire is remarkably increased, the effects of buffering and dispersing external force can be achieved, and the possibility that the electric wire falls off is reduced. The rubber nails and the rubber gaskets effectively increase tightness and play a role in protection, and meanwhile the two sets of wire guide wheels limit the electric wire.

The invention relates to the field of batteries, in particular to a pole piece and a preparation method thereof, a battery and a power utilization device. The pole piece comprises a current collector, a conductive buffer layer and an active layer which are sequentially stacked, at least one of the conductive buffer layer and the active layer comprises a carbon material, and the carbon material comprises one or more of graphite, soft carbon and football alkene. The pole piece can slow down the extrusion effect of the active material in the active layer on the current collector and reduce the extension of the current collector, so that the extension difference between the current collector and the active layer is reduced, and the problems of edge collapse of the active layer and belt breakage due to winding are solved.

The invention relates to a cathodic disbonding resistant coating which comprises a component A and a component B. The mass ratio of the component A to the component B is 20: (3-5). The component A comprises the following components in parts by weight: 25-31 parts of bisphenol A epoxy resin; 4-5 parts of a reactive diluent; 0.5 to 1.5 parts of an anti-sagging auxiliary agent; 0.3 to 0.8 part of a dispersant; 8 to 12 parts of titanium dioxide; 2-5 parts of iron oxide red; 5-8 parts of an anti-rust pigment; 2-3 parts of polyamide wax; 28-37 parts of a functional filler; the component B is phenolic aldehyde amine resin; the cathodic disbonding resistant coating disclosed by the invention is simple in preparation method, excellent in corrosion resistance, capable of being thickly coated and suitable for a long-term application environment.

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.
