The invention discloses a method for preparing a metal surface laser strengthened coat, which comprises the following steps: preparing uniformly mixed powder of titanium dioxide hydrate and graphite powder by using a wet chemistry method; pre-placing the mixed powder on the surface of a basal body; and irradiating the surface of the basal body by using laser as a heat source under an argon atmosphere to form a molten pool, performing a carbon-thermal chemical reaction on the pre-placed mixed powder under a high-temperature environment to generate titanium carbide, and finally forming a titanium carbide composite coat on the surface of the basal body. In the same way, the method is also suitable for preparing a TiN enhanced composite coat by mixing hydrated oxide thereof and graphite by the wet chemistry method, then mixing the mixture and urea to form pre-placed powder and cladding the pre-placed powder on the basal body by laser. The surface of the enhanced coat prepared by the technical scheme is smooth, and has no cracks or pores; enhancing particles are uniformly distributed in the coat; the enhanced coat and the basal body are metallurgically combined; and the mixed powder prepared by adopting the wet chemistry method is uniformly mixed, ensures complete reaction, and is suitable for industrial popularization and application.

The invention relates to a charge roller and a preparation method thereof. The charge roller comprises a metallic axle. The metallic axle is adhered with a polyurethane elastomer. The surface of the polyurethane elastomer is coated with a conductive surface layer the thickness of which is 10 to 40Mum. The polyurethane elastomer is made of prepolymer-R solution or prepolymer-P solution. The prepolymer-R solution contains conductive substances the weight percentage of which is 2 to 8 percent. The prepolymer-P solution comprises TDI the weight percentage of which is 50 to 70 percent. The charge roller of the invention is made of prepolymer materials. Therefore, the invention has the advantages of proper elasticity, good wear resistance, good heat resistance, good chemical stability and low compression deformation rate and is not likely to pollute the OPC drum.

The invention discloses an anti-siphon structure for a water inlet valve. The anti-siphon structure comprises an inner core pipe, a water inlet pipe, a waterstop mechanism, a sealing gasket and a sealing socket, an air inlet hole is formed in the sealing socket, the sealing socket and the sealing gasket are arranged in a matched manner, the inner core pipe is sleeved in the water inlet pipe, a water inlet channel is formed in the inner core pipe, the waterstop mechanism controls a water outlet of the water inlet channel to open or close, a water outlet channel is formed between the inner core pipe and the water inlet pipe, and a fitting surface is formed on the inner core pipe. When water enters, a water inlet of the inner core pipe is separated from the waterstop mechanism and opened, the sealing gasket and the fitting surface are opened, the air inlet hole in the sealing socket is plugged, so that a transitional channel is formed, and the water inlet channel is communicated with the water outlet channel by the transitional channel. When the water stops entering, the water inlet of the inner core pipe is plugged by the waterstop mechanism and closed, the sealing gasket returns and is fitted with the fitting surface, and an airflow channel is formed between the sealing gasket and the fitting surface. The anti-siphon structure is simple, fine in anti-siphon effect and accurate in CL (center line) marking.

The invention discloses a naringinase fermentation culture medium, a preparation method and a usage method thereof. The naringinase fermentation culture medium has following composition: 20 to 30g / L of starch, 2 to 10g / L of naringin, 0.5 to 6g / L of yeast extract, and 0.5 to 10g / L of bean powder, etc. In the preparation, most parts of starch, yeast extract, bean powder and other raw materials are weighed according to the weight ratio and added into water that occupies 2 / 3 to 3 / 4 of the total volume of a fermented fluid, pH value of the solution is adjusted to be 6.0, and the solution is sterilized and prepared into an initial fermentation culture medium; extra starch, yeast extract, bean powder and all the naringin are added into water that occupies 1 / 4 to 1 / 3 of the volume of a final fermented fluid, and the solution is sterilized and prepared into a material supplementary fluid. The culture medium and the preparation method can be used for preparing high-yield naringinase with the yield of 1100U in each milliliter of the fermented fluid or 55000U in each gram of a solid medium.

The invention discloses a metal material surface ultrasonic strengthening treatment device, specifically relates to the technical field of metal surface processing, comprising a support plate and feet, four corners of the bottom end of the support plate are fixedly connected with feet, the bottom of the support plate The end is equipped with a dust-proof mechanism. The invention utilizes the metal material to frictionally drive the rubber wheel to rotate during the reciprocating motion. During the rotation, the rubber wheel is driven to drive the second friction wheel to rotate due to the friction force, and the second friction wheel friction drives the first friction wheel to rotate, thereby making the first friction wheel rotate. Wheel friction drives the hopper to rotate, and the fan blades installed in the hopper agitate the airflow to flow downward, accelerating the dust to move down to the dust-proof mechanism, so as to prevent the dust from spreading to the periphery of the hopper, and during the rotation of the hopper, the material rod will be scraped The inner wall of the receiving hopper can be cleaned through the inner wall, which is convenient for cleaning and collecting the dust falling into the receiving hopper.

The invention discloses a method for immobilizing organophosphorus ester of pollutants during co-pyrolysis. The method is characterized in that a mixed solution of CaCl2 and MgCl2.6H2O is sprayed onto a mixture of lignin-containing biomass and plastics, the mixture is dried to be used as a feeding material, and then the material is subjected to pyrolysis at 400-600 DEG C. According to the method, free radicals generated by pyrolysis of lignin in biomass react with thermal decomposition products of organophosphorus ester, so that organophosphorus ester is immobilized in charcoal in a plastic and biomass co-pyrolysis process through pyrolysis temperature control; more organophosphorus ester can be immobilized in charcoal under the strengthening effect of CaCl2 and MgCl2.6H2O, the risk that phosphorus containing pollutants are released in the environment is reduced, and environment pollution is avoided; the operating method is simple and easy to implement, and the method provided by the invention can be applied to organophosphorus ester containing waste plastic treatment.
