The invention discloses nanometer antibacterial mildewproof coating. The invention comprises the following components according to the weight percentage of The invention of water-based coating, 3 to 7 percent of nanometer silver, 3 to 7 percent of nanometer copper or nanometer zinc occupies, and 4 to 11 percent of nanometer zinc oxide or nanometer titanium dioxide. The application of the nanometer antibacterial mildewproof coating is as follows: the nanometer antibacterial mildewproof coating is evenly painted on the medical instruments, the medical furniture and the indoor wall bodies of a hospital, such as hospital beds, bedside cabinets, hospital carts, office tables and chairs of a hospital, so as to ensure the surfaces of the articles to be covered through the coating, when harmful microorganisms in air or at the parts of human hands are contacted with the articles, the harmful microorganisms left on the articles are captured and killed through the metallic ions with positive charge in the nanometer antibacterial mildewproof coating, and therefore the invention prevents the cross spreading of the harmful microorganisms in the hospital.

The present invention discloses a method for reduction of beam section height by use of unbonded steel strand prestress, the method comprises reduction of the beam section height by use of external prestress and reduction of the beam section height by use of internal prestress, when the number of desired steel strands is not more than 6, or the number of desired steel strands is more than 6, but anchoring of both ends can be treated, an external prestress method is used; and when the number of the desired steel strands is greater, and anchoring of ends of the steel strands cannot be treated, an internal prestress method is used. The method is simple in construction, uninstall and additional arrangement of a temporary support are not needed, construction period is short, cost is low, an upper structure is not affected, and the method has the advantages that service life is synchronous with that of an original structure.

The invention provides a ceramic or enamel sterilization glaze material and a preparation method and application thereof. The ceramic or enamel sterilization glaze material is prepared from, by weight, 80-90% of ceramic or enamel glaze materials, 5-15% of silver powder and 5-15% of copper oxide powder or zinc oxide powder. By the adoption of the technical scheme, the surface of a ceramic or enamel product has the excellent sterilization and mould-proof ability, and the sterilization effect is kept synchronous with the service life of the ceramic or enamel product; the material components are environmentally friendly, and using safety of the ceramic or enamel product is ensured.

The invention relates to a baffle applied to a tundish of a profiled blank conticaster and a preparing method thereof, belonging to the technical field of the profiled blank continuous casting tundish process in ferrous metallurgy. A guide plate (2) adopts magnesium preformed unit. The baffle is of arc monolithic structure, the arc degree alpha is 90-95 degrees, and a dovetail groove (6) is arranged on the two sides. The guide plate (2) is arranged on the external side of a current stabilizer (1). The upper edge of the guide plate (2) is 120-150mm higher than the upper edge of the current stabilizer (1). Slag blocking dams (3) are respectively arranged between the external side of the dovetail groove (6) of the guide plate (2) and the external side of two sizing nozzles (4) of a middle casting flow. By the shunting function of the guide plate, the compositions and the temperature of molten steel in the tundish of the profiled blank are uniformed. The temperature difference of three casting flows of the profiled blank is lowered from 12 DEG C to 4 DEG C. Casting blank quality defects and steel breakout accidents caused by high molten steel temperature of the middle casting flow aresolved. Simultaneously, the upward floating elimination of inclusions is promoted. The qualified rate of the profiled blank is improved and reaches more than 99.7 percent.

The invention discloses a lightweight high-temperature-resistant heat-insulating board for metallurgy and a preparation method thereof. The board comprises the following raw materials by weight: 10 to70% of vitrified microbeads, 10 to 70% of floating beads, 0 to 30% of magnesia, 0 to 20% bauxite cement, 0 to 8% of Guangxi white clay, 0.02 to 5% of a binder, 0 to 10% silica micropowder, 0 to 15% of pyrophyllite powder and 0 to 3% of quicklime. The preparation method comprises the following steps: uniformly mixing the desired amounts of the raw materials with water in a mixer to obtain a mixture; placing the mixture in a mold for vibrating formation to obtain a molded product; storing the molded product with a mold at room temperature for 8 to 48 h; then putting the molded product with themold into an incubator with a temperature of 50 to 80 DEG C and maintaining the product at the temperature for 8 to 24 h; and then carrying out demolding, and drying the molded product in a drying boxwith a temperature of 120-200 DEG C for 8 to 48 h so as to obtain the lightweight high-temperature-resistant heat-insulating board. The board provided by the invention has the characteristics of light weight, high strength, excellent heat insulation performance and the like.

The invention relates to the technical field of rotary kiln liner fireproof materials, particularly to a repairing method of a rotary kiln liner fireproof material. The repairing method comprises the following steps of: 1. removing a ring formation layer on the surface of the rotary kiln liner fireproof material to avoid decompacting an unloosed part through excessive mechanical vibration force; 2. welding a metallic network frame structure, and fixing the metallic network frame structure onto a rivet of a kiln burnt brick or a casting strap through a U-shaped nail and a Y-shaped nail; 3. brushing a bond on a working surface, casting a fireproof material on the brushed bond to form a fireproof material casting strap, and arranging a furnace body shrinkage joint plate between the casting straps; 4. after finishing casting, curing for 65-80 hours to achieve the optimal cold strength of the fireproof material; and 5. preserving heat and baking a furnace in segments to the temperature of 600 DEG C. The repairing method of the rotary kiln liner fireproof material can effectively prevent the continuous falling-off of a rotary kiln liner and avoid the influence generated by hot spot accidents; and the high temperature segment and the low temperature segment of a rotary kiln are relatively synchronous, thereby prolonging the service life of the kiln liner.
