The application provides a high-solid-content fireproof glue and a preparation method thereof. The raw materials of the fireproof glue include aggregates, an anti-freezing agent, a dispersing agent, a curing agent and a defoaming agent. The aggregates include inorganic materials and metal oxides. The inorganic materials are silica sol and / or water glass, and the metal oxides are zirconium oxide and / or magnesium oxide. The mass of the dispersing agent is 1 wt% to 5 wt% of the mass of the fireproof glue, and the dispersing agent includes vitamin E succinate polyethylene glycol ester. The mass of the anti-freezing agent is 0.5 wt% to 5 wt% of the mass of the fireproof glue. The volume-mass ratio of the curing agent to the inorganic materials is 0.5 to 2 mL:10 g. The application uses vitamin E succinate polyethylene glycol ester (TPGS) as the dispersing agent, so that the solid particles of metal oxides with stable chemical properties, such as zirconium oxide and magnesium oxide, can be effectively added in the preparation process of the fireproof glue liquid. The problems that the salts containing zirconium and magnesium or the organic raw materials are prone to react or decompose in an alkaline environment are overcome, and the fire resistance and the heat insulation effect of the fireproof glue are significantly improved.

The application discloses a device for preparing heparin sodium without salt extraction, which comprises a preparation cylinder, a vertical rotating sleeve is arranged in the preparation cylinder, an arc-shaped tube is rotationally connected to the outer peripheral wall of the vertical rotating sleeve through a supporting tube, a magnetic supporting body is arranged on the outer wall of the arc-shaped tube close to the bottom of one end, a hanging shaft is arranged in the vertical rotating sleeve and can slide up and down, a filter screen plate is arranged at the bottom of the hanging shaft, an annular electromagnetic plate is fixedly connected to the outer periphery of the filter screen plate and is in sealing sliding connection with the inner wall of the preparation cylinder, and the annular electromagnetic plate is located below the magnetic supporting body. In the application, the arc-shaped tube is arranged in the preparation cylinder and can rotate and swing up and down, when the arc-shaped tube moves, the exchange resin accumulated above the filter screen plate in the preparation cylinder is drained and dispersed upward, so that the heparin sodium pretreatment liquid and the exchange resin are fully contacted, and the ion exchange efficiency is improved.

The application discloses a bearing for a vertical shaft, comprising an outer ring and an inner ring, two rows of retainers are arranged between the outer ring and the inner ring, rolling bodies are assembled in the retainers, the retainers comprise an upper edge part, a pocket part and a lower edge part, the upper edge part is arranged along the axial direction of the outer ring, the lower edge part is arranged along the radial direction of the outer ring, the pocket part is arranged obliquely, a plurality of pockets are arranged on the pocket part, pocket beams are formed between adjacent pockets on the pocket part, a plurality of outer convex ribs are arranged obliquely on the outer circumferential wall of the retainer, a plurality of inner convex ribs are arranged obliquely on the inner circumferential wall of the retainer, and the inner convex ribs and the outer convex ribs are arranged at positions corresponding to the pocket beams. The bearing has the advantages of simple structure, effective solution to the problems of uneven distribution of lubricating grease, double-row bearing lubricating grease flow and poor sealing reliability in the prior art, and effective improvement of the operation stability and service life of the bearing.

The invention relates to the technical field of compound fertilizers, and provides a high-temperature-resistant bacteria-containing compound fertilizer and a preparation method thereof.The preparation method comprises the following steps that nanoscale freeze-dried bacterial powder is prepared from bacillus, bacillus stearothermophilus and rhodopseudomonas palustris; mixing the nano TiO2 modified SiO2 composite aerogel, diatomite, the modified charcoal, sepiolite and pullulan to prepare a microbial inoculum protection composite carrier; and mixing the freeze-dried bacterial powder with a carrier, and drying to obtain the micron-sized capsule bacterial agent. Uniformly mixing a reinforcing agent, a plasticizer and a stabilizer to prepare a performance regulator; the preparation method comprises the following steps: melting choline chloride-containing urea and monoammonium phosphate to prepare molten slurry; mixing the molten slurry with a compound fertilizer to form uniform slurry; and mixing the slurry with a micron-sized capsule microbial inoculum and a performance regulator, and granulating to obtain the high-temperature-resistant bacterium-containing compound fertilizer. By optimizing the adaptability of a microbial agent embedding carrier and a melting system, the technical bottleneck of conflict between high-temperature inactivation of the microbial agent and physical properties of a product is solved.
