The invention provides a milk source Kluyveromyces marxianus and application of the milk source Kluyveromyces marxianus in preparation of milk residues, the Kluyveromyces marxianus is preserved in the China Center for Type Culture Collection, and the preservation number is CCTCC (China Center for Type Culture Collection) NO: M20221259. Compared with other saccharomycetes, the kluyveromyces marxianus SY11 can more effectively decompose protein in cow milk to generate amino acid, generate a proper amount of alcohol and carbon dioxide, promote cow milk solidification and whey removal and form a uniform porous structure in the preparation of the milk residues, and compared with commercially available milk residues, the prepared milk residues are milky white in color and free of toxic and side effects. The taste and the texture are better.

The invention provides a carbon anode plate for fluorine preparation and a preparation method and application thereof, and belongs to the technical field of carbon anode plates. Eutectic prepared from aluminum fluoride, calcium fluoride and lithium fluoride is mixed with carbon nanotube / carbon black aggregate particles, needle coke and medium-temperature coal pitch, a carbon anode plate is prepared through a conventional carbon plate manufacturing process, carbon chemical vapor deposition and copper electroplating are performed on the surface, and the carbon anode plate for fluorine preparation is prepared. The preparation method of the carbon anode plate for fluorine preparation is simple, the generation of polarization of the carbon anode plate is prevented, and the carbon anode plate has the advantages of low porosity, low ash content, high mechanical strength, high volume density, obviously prolonged service life, low resistivity and the like, and has a wide application prospect.

The invention discloses a preparation method of porous catalyst slurry and a multi-layer microporous catalyst layer and application of the porous catalyst slurry and the multi-layer microporous catalyst layer in a membrane electrode. Solid catalyst particles are gradually added into water containing a buffer solution and a hydrophobic modified substance; the slurry suspension is placed in a ball mill to be subjected to homogenization treatment for preset time, and modified suspension is obtained; stirring the modified suspension in a container, and adding a high-molecular ionomer solution and a buffer solution; and carrying out primary stirring and secondary stirring through an eggbeater to obtain foamed porous catalyst slurry. Hydrophobically modified catalyst particle slurry is obtained, foaming is performed in a mechanical stirring mode, pores are formed in the slurry, the preparation mode is simple, pores in the formed slurry are uniform, the use amount of the catalyst can be greatly reduced under the condition that the catalytic efficiency is not affected, and by coating porous catalyst slurry with different pore diameters for multiple times, the catalytic efficiency of the catalyst is greatly improved. And gas molecules can be quickly generated and diffused, so that the catalytic active sites are prevented from being blocked.

This invention relates to the field of dialysis paper technology, and particularly to a fiber pretreatment method for dialysis paper and dialysis paper itself. The fiber pretreatment method for dialysis paper includes the following steps: Step 1, weighing softwood fibers, broadwood fibers, and regenerated fibers and placing them in deionized water, stirring thoroughly to obtain a mixture; Step 2, adding an initiator to the mixture, heating to 35-45°C, and mixing evenly; Step 3, adding modified nanoparticles to the mixture from Step 2, and stirring continuously for 4-6 hours; Step 4, after the reaction is complete, washing, filtering, and drying to obtain the pretreated fibers for dialysis paper. The fiber pretreatment method for dialysis paper proposed in this invention can uniformly attach nanoparticles to the fiber surface. When the nanoparticles are compressed by the fibers, they can aggregate towards the "gaps" between the fibers, preventing excessively large gaps between the fibers and avoiding the passage of bacteria or dust through the dialysis paper.

The application discloses a manganese-zinc ferrite and a preparation method thereof, and the method comprises the following steps: mixing manganese-zinc ferrite powder and a polyvinyl alcohol solution to obtain a mixture, and grinding the mixture; performing a compression molding treatment on the ground mixture to obtain a compression molding product; and performing a sintering treatment on the compression molding product to obtain the manganese-zinc ferrite; wherein the sintering treatment comprises a temperature rising treatment stage, and the temperature rising treatment stage comprises a plurality of temperature rising stages, at least two of which have different temperature rising rates. The manganese-zinc ferrite prepared by the application can have a high saturation magnetic flux density and a low residual magnetism while keeping a low loss at a high frequency, that is, the manganese-zinc ferrite with a large magnetic induction intensity change amount is prepared.
