According to the technical scheme, the user and / or an administrator can edit different watermarkcontents so that the requirement of watermark management for the administrator can be met, and the personalized requirements of watermark setting for different users can be met.

The invention discloses a method for changing wettability of the surface of metallic nickel through hydrofluoric acid etching. The method comprises the steps that (1) an ultrasonic cleaning mode is adopted to wash the surface of the metallic nickel, and oil stains and impurities on the surface of metallic nickel sheets are removed; (2) the metallic nickel sheets are put into a hydrofluoric acid solution with the concentration being 40% or above, and then are put into a water bath with the temperature being over 30 DEG C to be subjected to chemical etching for 7-28 hours, and in the etching process, the surfaces of the metallic nickel sheets are turned once every one hour; and (3) the etched metallic nickel sheets are taken out, flushed and dried, and the metallic nickel sheets with the wettability being changed are obtained. The surface of the metallic nickel is subjected to etching treatment through the hydrofluoric acid solution, rough microcosmic structures are formed on the surface of the metallic nickel, and accordingly the wettability of the metallic nickel is changed only in the mode of improving the surface roughness, hydrophobicity of the surface of the metallic nickel is improved, then the service life of the metallic nickel under the wet or vapor condition is effectively prolonged, and the application range of the nickel is widened.

The invention relates to a brick cutting machine, in particular to a building brick cutting machine. The invention aims to provide the building brick cutting machine, wherein the building brick cutting machine is characterized by being capable of replacing workers to cut off bricks, so that labor is saved, and hands cannot be knocked and hurt by a tool. According to the technical description scheme, the building brick cutting machine comprises a base, a workbench, a first mounting plate, an elastic plate, a mounting rod, a pressing cutter, a first limiting block, a motor, a first rotating shaft, a swing rod, rollers and the like; and the workbench for placing the bricks is fixedly connected to the middle of the top of the base, the first mounting plate is fixedly connected to the rear partof the right side of the top of the base, and the first mounting plate is located on the rear side of the workbench and is in contact with the workbench. According to the building brick cutting machine, the bricks are placed on the workbench, the motor is started to rotate forwards, so that the bricks can be pressed and fixed by a pressing plate, then the pressing cutter moves downwards to cut off the bricks, so that the bricks are fixed without holding the tool with the hands by people, more labor is saved, and the hands can be prevented from being knocked and hurt by the tool.

The invention discloses a time-delay fuse. The fuse comprises an outer box, power connection sheets penetrate through and are inserted into two symmetrical side walls of the outer box, and an adsorption plate is fixed to the inner wall of the outer box. A conductive rod is inserted into the side wall of the adsorption plate in a penetrating manner, power connection plates are fixed to the two endsof the conductive rod, and a battery is fixed to the inner wall of the outer box. A contraction spring is fixed to the side wall, away from the adsorption plate, of the power connection plate, and aconductive plate is fixed to the end, close to the adsorption plate, of the contraction spring. The time-delay fuse has the advantages that the conductive plate is in contact with the power connectionplate, an external power utilization circuit is electrified through the connection of the contraction spring, when a fault current of the circuit is increased, the contraction spring can complete contraction action at the moment when the current is increased, so that the conductive plate is separated from the power connection plate, the external circuit is rapidly disconnected, the external circuit and an electric appliance are prevented from being impacted by a high current, and the external circuit and the electric appliance are protected.

The invention discloses an ELISA (enzyme-linked immunosorbent assay) plate coating liquid and an ELISA plate confining liquid. The ELISA plate coating liquid contains a carbonate buffer solution with pH of 9.6 and G-6-PD, and the ELISA plate confining liquid contains a phosphate buffer solution with pH of 8.0, NADP<+> and G-6-P. The invention further discloses a method for manufacturing a pre-coated ELISA plate through matching use of the ELISA plate coating liquid and the ELISA plate confining liquid. According to the method for manufacturing the pre-coated ELISA plate, G-6-PD and a to-be-coated antigen or antibody are coated together in the coating process, NADP<+> can be reduced into NADPH during closing, coating uniformity of G-6-PD can be indirectly detected through detection of NADPH, then the coating uniformity of the antigen or antibody is reflected, accordingly, an unqualified pre-coated ELISA plate is identified in a manufacturing process, and the quality of the pre-coated ELISA plate can be guaranteed.

The invention discloses a spraying device for a copper rod. The spraying device comprises a storage box and a spraying mechanism connected with the storage box, wherein the spraying mechanism comprises a hollow columnar shell; an upper connecting and guiding opening is formed in the top of the shell; a lower connecting and guiding opening is formed in the bottom of the shell; the upper connectingand guiding opening and the lower connecting and guiding opening are coaxially arranged; a nozzle connected with the storage box is arranged in the shell; and a power mechanism is arranged on the storage box. According to the spraying device, a thin anti-oxidation layer can be formed on the surface of the copper rod, the problem that the copper rod is exposed in air for a long time and is oxidizedcan be effectively solved, and the appearance and quality of subsequent products are guaranteed. The invention further discloses an online spraying system. The anti-oxidation spraying device is arranged between a traction mechanism and a rod throwing mechanism, transferring labor is saved, transferring time is shortened, transferring cost is reduced, and efficiency is improved. Meanwhile, the whole process is continuous, under the condition that normal production of a copper rod continuous rolling machine is not affected, the problem that the copper rod is exposed in air for a long time and is prone to being oxidized is solved, efficiency is high, and cost is low.
