The invention discloses a vertically open ice-breaking high-voltage isolating switch. The upper part of the operating pull rod (11) is hinged to one end of the ice-breaking connecting rod (10), and the other end of the ice-breaking connecting rod (10) is hinged to breaking crampons (7); The inner side of the moving contact area of ​​12) is provided with ice-breaking claws (7) that can slide longitudinally along the surface of the moving contact of the conductive arm. The tail of the ice-breaking claws (7) is hinged with the ice-breaking connecting rod (10). One end is hinged with the operating pull rod (11). The invention makes use of the low shear strength of ice to drive the movement of the ice-breaking mechanism at the same time as the movement of the moving contact pull rod, so as to realize the ice-breaking of the moving contact during the closing process, and then the ice-free moving contact is operated by the operating mechanism. Then break the ice on the static contact. The structure is simple and reasonable, and the work is reliable, which can meet the requirements of fast ice breaking.

The present invention relates to the technical field of inkjet printing, in particular to a color-promoting ceramic ink-jet printing ink and a preparation method thereof. The color-promoting ceramic ink-jet printing ink comprises the following components: fused silica, calcined zinc oxide, water Aluminum stone, zirconium silicate, high-temperature frit, dispersant, defoamer and solvent, the ceramic inkjet printing ink that promotes color development is well combined with surface glaze and other color inks, in addition, the ceramic inkjet printing ink that promotes color development If printing ink is printed on the top glaze, it can also improve the whiteness of the top glaze without affecting the texture of the product. On the other hand, the amount of inkjet of color ink can be greatly reduced, which is beneficial to reduce the production cost of ceramic tiles. The preparation method of the color-promoting ceramic ink-jet printing ink has the characteristics of simple method, low production cost, and being applicable to large-scale industrial production.

The invention relates to a double-link rapid detection card for detecting and distinguishing O-type and A-type foot-and-mouth disease viruses and a preparation method thereof. The detection card uses the principle of double-antibody sandwich ELISA to detect antigens. The monoclonal antibody mAbI that can specifically recognize the O-type foot-and-mouth disease virus and the monoclonal antibody mAbII that can specifically recognize the A-type foot-and-mouth disease virus are sprayed onto the detection membrane (nitrocellulose membrane) ) at the T1 and T2 detection line positions to prepare a detection imprint; spray goat or rabbit anti-mouse IgG or SPA to the C line position of the quality control area of ​​the detection membrane to prepare a quality control imprint. The gold-labeled antibody fiber layer is divided into upper and lower layers, which are respectively adsorbed with colloidal gold-labeled monoclonal antibody mAbIII that can specifically recognize type O foot-and-mouth disease virus and monoclonal antibody mAbIV that can specifically recognize type A foot-and-mouth disease virus. The test strip can be used for rapid detection of O-type and A-type foot-and-mouth disease virus (FMDV) infection. By applying the invention, the operation is simple and fast, the result is clear and easy to argue, and is suitable for popularization at the grassroots level.

The invention discloses a method for preparing a gradient copper matrix composite material and for integrating a part. The method comprises the steps of preparing reaction flakes with different proportions; laminating the reaction flakes according to the Cu content gradient; subjecting the reaction flakes to cold pressing in a mould to obtain a prefabricated reaction block; fixing the prefabricated reaction block on the top part of the die cavity of a sand-type mould or a metal-type mould; melting pure copper in a pot resistance furnace and heating the pure copper to 1133 DEG C-1183 DEG C; and then casting to obtain the copper matrix composite material with Al2O3 content distributed in gradient on the surface of a part. The method utilizes high temperature Cu to ignite the prefabricated block containing Al powder, CuO powder and Cu powder in gradient lamination, realizes the integration of strengthening the part surface gradient and shaping the part, thereby reducing cost, strengthening the strength and the performance of high temperature creep resistance and abrasion resistance of the copper matrix composite material, and improving the quality of the part.
