The invention provides a new preparation technology of a ceramic antibacterial agent capable of resisting high-temperature sintering. The new preparation technology is characterized in that the antibacterial active agent is subjected to surface coating by the nano inorganic material so that the coated antibacterial active agent has obvious high-temperature resistant property. The adopted coated material is silicon oxide, zirconium phosphate, or multicomponent inorganic material such as 0.5xAl2O3-(2-0.75x)SiO2-1.0ZnO-2.0CaO(x is 0.0-1.0), and antibacterial active center is silver oxide. After the coated antibacterial active material is calcinated for 30 minutes at 1250 DEG C to 1350 DEG C, the antibacterial activity is still evident, the defect of bad high-temperature resistant property of the existing antibacterial agent is overcome, and the quantity of the antibacterial active agent added to glaze can be obviously reduced. The coated antibacterial active material can be directly added to glaze water and is uniformly mixed for direct glazing, and high-temperature calcination is finally carried out to prepare antibacterial ceramic. The antibacterial ratio of the prepared antibacterial ceramic to common viruses and bacteria such as escherichia coli, staphylococcus aureus is more than 99%.

The invention relates to a 3D printing mud and a preparation method thereof, comprising: mixing a filler, a polysiloxane, a coupling agent and an activator according to a certain proportion; heating and reacting to form a 3D printing mud. This method utilizes the reaction between the coupling agent and the reactive polysiloxane to increase the viscosity between the printing paste and the paste, and then adjusts the relationship between the coupling agent and the polysiloxane by adding an activator. The breaking and repairing of the chemical bonds of the hollow ions greatly reduces its specific gravity through the introduction of hollow ions, so that it is light in weight, smooth and easy to shape, lubricated and soft, non-slippery, non-sticky, non-slagging, and has a long service life. Effectively inhibit bacteria and mold and other excellent properties.

The invention relates to a fast diffusion welding connection method for a skutterudite thermoelectric material and an electrode, and relates to a diffusion welding connection method. The purpose is to solve the problems of Sb element volatilization and element diffusion when the existing skutterudite thermoelectric material is connected with electrodes. Method: Take the electrode and clean the surface to be welded, plate an alloy barrier layer on the surface of the electrode to be welded, clean the surface to be welded with skutterudite thermoelectric material, and perform diffusion welding. The present invention prepares the barrier layer by electroplating on the electrode side, and then realizes diffusion welding with the skutterudite thermoelectric material at a relatively low pressure and relatively low temperature, and there is no element diffusion between the weld element and the skutterudite in the process , can prevent the volatilization of Sb element and the occurrence of element diffusion. The invention is suitable for welding skutterudite thermoelectric materials and electrodes.

The present invention discloses a process for preparing a solid versatile adhesive, which comprises the steps of: 1) filtering a slurry of the solid versatile adhesive by a filter screen with 80-100 mesh; 2) spraying the slurry of the solid versatile adhesive after filtration from step 1) onto a base film under pressure to a thickness of 1-2 mm; 3) transporting the base film coated with the slurry of the solid versatile adhesive from step 2) to an oven at 40-85 ºC and drying for 1-5 min; 4) laminating a top film to the solid versatile adhesive layer on the base film from step 3) by using a film laminator under a pressure of 60-80 N / cm2 for 5-30 s, to obtain a solid versatile adhesive in a thin film form; 5) subjecting the solid versatile adhesive from step 4) to edge-cutting and sealing. The product made by the present process is in the form of film, which enables the end user to manufacture it in any shape as required. Such product is uniformly coated and can be used quickly and conveniently.

The invention discloses a one-step zinc smelting method of spraying zinc concentrate in a molten pool, which comprises the following steps: a. mixing the zinc concentrate with a flux and drying to obtain a mixed material; b. drying the mixed material obtained in the step a Spray directly into the molten pool of the jet smelting zone through the side blowing lance, react with oxygen-containing gas to oxidize and desulfurize, and obtain high-grade zinc slag and smelting flue gas; c, send the high-grade zinc slag obtained in step b into the electrothermal reduction zone for reduction to obtain Zinc vapor and slag. In the method of the present invention, by changing the feeding mode of the material, the mixed material is directly sprayed into the molten pool of the jet smelting zone by using a side-blown spray gun after drying, so that the zinc content in the flue gas in the smelting zone is significantly reduced, and the direct absorption of zinc is greatly improved. Yield, the zinc content of the slag obtained after reduction can be reduced to less than 0.1%. The slag yield is low and the amount of slag is small. It can be directly sold as general solid waste. The production capacity of a single series of zinc can meet the requirements of 5-50 million tons / year. kind of scale.
