The invention discloses a process for preparing a V2O3 / ZnV2O3 total battery by simultaneously using vanadium oxide in a zinc ion battery as a positive electrode material and a negative electrode material, which comprises the following steps: reacting ammonium metavanadate with absolute ethyl alcohol by adopting a solvothermal synthesis method, washing, drying, and calcining in a tubular furnace to obtain V2O3; in the preparation process of the V2O3 positive electrode material, only V2O3, acetylene black serving as a conductive agent and PVDF serving as a binder are mixed in proportion and then are coated on graphite paper, other coating protection materials do not need to be introduced into a V2O3 / Zn negative electrode, and V2O3 is used as a protection layer to inhibit growth of zinc dendrites, relieve hydrogen evolution side reaction of the zinc negative electrode and reduce corrosion of zinc. Vanadium oxide V2O3 is directly used as a core positive electrode material, the zinc negative electrode coating is developed by utilizing the characteristics of the vanadium oxide V2O3, a material is formed, meanwhile, the performance optimization of the positive electrode and the negative electrode is realized, the used raw materials are simple and easy to obtain, the process is simple and easy to implement, and the preparation process is simple and easy to implement from V2O3 raw material synthesis to positive and negative electrode piece preparation to V2O3 / ZnV2O3 total battery assembly. And comprehensive improvement of positive and negative electrode performances of zinc ions is simultaneously realized by a single material.

The utility model discloses foamed ceramic pressing equipment, and belongs to the technical field of foamed ceramics. The mold mainly comprises a mold body, an opening is formed in the top of the mold body, and a containing cavity is formed in the mold body; the pressing plate is hinged to the interior of the containing cavity, and one end of the pressing plate is connected with a first air cylinder; the gate is arranged on one side of the accommodating cavity; the sweeping mechanism is arranged on the side, away from the gate, in the containing cavity, the sweeping mechanism comprises a second air cylinder, the second air cylinder is fixedly installed on one side of the mold, and the output end of the second air cylinder penetrates through and extends into the containing cavity; the push plate is fixedly mounted at the output end of the second air cylinder; and at least two groups of scraping strips. According to the foamed ceramic pressing equipment, the sweeping mechanism is arranged, so that materials on the inner wall of the containing cavity can be removed while pressed foamed ceramic is discharged through the push plate, and the whole operation process is cleaner and more efficient.

The electric scissors have the advantages that the stability and the fineness are increased, and the scissors are cleaner during operation.

The object of the present invention is to provide an antiseptic composition that can reduce the risk of an incise drape coming off from the skin, without adversely affecting microbicidal activity, even when the incise drape is affixed to skin surface after application of the antiseptic composition, and / or exerts more effective microbicidal activity. A composition comprising a microbicide and a sugar alcohol is used as the antiseptic composition.

The present invention discloses an unloading device, unloading system and control method for a low-temperature liquid tank truck. The unloading device includes a compressor, a regenerator, a cooling device, a control valve group, and also includes a low-temperature liquid storage tank interface and a tank truck interface. The control valve group selects to connect the storage tank interface with the second heat exchange outlet and / or the first heat exchange inlet of the regenerator, and connects the tank truck interface with the first heat exchange inlet and / or the second heat exchange outlet. The device, system and control method of the present invention are simple to operate, can efficiently realize normal temperature pressurized unloading, and are suitable for existing gas filling stations.

The invention provides a needle tube sampling method. The needle tube sampling method comprises the following steps: S1, communicating a first pipeline with a sampling needle and an oil discharge port; a second pipeline is communicated with the first pipeline and the waste oil tank, and a first switch valve is used for controlling on-off of the second pipeline; s2, an oil discharge outlet is opened, oil in to-be-detected equipment enters the sampling needle tube, after the oil entering the sampling needle tube reaches a preset volume, the oil discharge outlet stops discharging oil, a first switch valve is opened, a piston rod of the sampling needle tube is reversely pushed until the piston rod reaches a zero position, one-time cleaning is completed, and the cleaning steps are repeated until preset cleaning times are completed; s3, oil is discharged through an oil discharge port, oil in the to-be-detected equipment enters the cleaned sampling needle tube, after the oil entering the sampling needle tube reaches the preset volume, oil discharge is stopped through the oil discharge port, and sampling is completed. Compared with a conventional sampling mode, the sampling mode provided by the invention has the advantages that the insulating oil is not in contact with external air in the whole process, the final detection accuracy is ensured, and the waste is less.
