The invention discloses a method for preparing ultra-pure hydrogen. The electrolytic hydrogen production process is adopted in the method. Softened water before electrolysis is pretreated, the softened water is heated, and various sorts of gases like N2 and Ar dissolved in the softened water are removed completely; high-purity oxygen is supplied for pressure maintaining; and then the ultra-pure hydrogen meeting 'GBT 3634.2-2011 pure hydrogen, high-purity hydrogen and ultra-pure hydrogen' requirements can be produced by the adoption of the catalyst catalytic deoxidation and molecular sieve dehydration process, filtering dust removal process and steel cylinder drying treatment process. The method for preparing the ultra-pure hydrogen has the beneficial effects that the defects that a palladium alloy diffusion film (pipe) separation method is high in cost and small in production amount, a hydrogen storage alloy absorbing and desorbing method is short in hydride service life and instable in production, a low-temperature adsorption method needs to use liquid nitrogen and thus the requirements for equipment are high are overcome successfully; and the characteristics of being low in production energy consumption, high in flow-path efficiency, simple in process, stable in production and the like are achieved.

This invention discloses an activator used in large-doping-amount finely ground slag concrete. The activator is composed of: gypsum 60-81 wt.%, naphthalin high-performance water reducer 7-10 wt.%, hydroxyl compound 0-0.02 wt.%, surfactant 0-0.002 wt.%, and finely ground slag 9-30 wt.%. The activator can replace 4-6% of cement in large-doping-amount finely ground slag. The concrete added with the activator has such advantages as high mixability, high pumpability, and high volume stability. With the activator, the doping amount of finely ground slag in the concrete can be increased to 70%.

The invention provides a method for extracting red pigment from a fruit of Viburnum sargentii, and relates to the method for extracting pigments from the fruit of Viburnum sargentii. The invention solves the problem that no prior method is specially for extracting the red pigment from the fruit of Viburnum sargentii. The red pigment of the fruit of Viburnum sargentii is extracted according to thefollowing steps: acetic acid-sodium acetate solution, pectinase, and the fruit of Viburnum sargentii are put in a mixer and broken to homogenate, infused to a 15 mL plug pipe, and then put in a thermostat water bath; enzymolysis is conducted; the enzymolysis liquid is filtered; the filtrate is rotationally evaporated to remove the solvent, and cooled and dried; and red pigment powder of Viburnum sargentii is acquired. The method uses the pectinase to extract the red pigment of Viburnum sargentii, thereby avoiding the problems of low production rate, low purity, residual solvent, difficult solvent recycling, and long production cycle produced when a solvent method is used to extract the red pigment. The method has the advantages of high production rate and short production cycle; and the acquired red pigment belongs to flavonoid naturalpigment, has no harm to a human body, and can be used for coloring food.

The invention belongs to the field of material preparation, and discloses a device and method for preparing aluminum foam by using a bottom blowing powder spraying method. The powder spraying system transports foaming gas and fluidized additive particles to slit-type breathable bricks through a blowing pipeline. The foaming gas and particles are blown into the molten aluminum from the bottom of the foaming chamber by the slit-type breathable brick, and the two processes of adding particle stirring and blowing foam in the traditional aluminum foam preparation process are simplified to blowing gas and particles together Aluminum liquid, the bubbles float up to form foam, which is collected, cooled, annealed and rolled by the rolling system to realize the continuous production of foamed aluminum; the device for preparing foamed aluminum by the bottom blowing powder spraying method includes powder spraying system, blowing pipeline, Slit-type air-permeable bricks, crucibles, agitators and rolling systems; the invention uses the method of bottom blowing and powder spraying to blow gas and particles into the aluminum liquid at the same time, so that the particles are evenly dispersed and not easy to agglomerate, and the particle dispersibility is improved. The performance of the aluminum foam material is improved, and the production power consumption is reduced at the same time.

The invention discloses a finishing rolling unit in ESP endless rolling and a rolling method, and belongs to the field of steel and iron material engineering. The finishing rolling unit in the ESP endless rolling of the invention comprises a plurality of finishing mills arranged in the order of a finishing rolling process, and is characterized in that one of the finishing mills is a standby finishing mill for replacing the worn finishing mill; a spray header is arranged in front of the preceding finishing mill in the standby finishing mill and the worn finishing mill by the order; and the spray header spray cold water to cool a strip plate to complete the transformation process of austenite to ferrite. According to the invention, the full-continuous non-stop flexible rolling technology canbe realized, the productivity drop caused by the forced stop of the production line due to the downtime and roll change of the finishing rolling unit is avoided, and the output is also improved; andthe roll temperature rise can be reduced, so that the fatigue cracking and fracturing of the roll due to the thermal stress are reduced, the wear of the roll is reduced, the surface quality of endlessrolled products is improved, and the production cost is significantly lowered.

The invention discloses a dynamic variable procedure ferrite rolling method based on endless rolling. A cooling channel is arranged between induction heating and a finishing rolling mill group, and the temperature matching is adjusted and controlled between the induction heating and the cooling channel, so that the finishing rolling mill group realizes austenite zone rolling and ferrite zone rolling in the dynamic variable procedure correspondingly. The ferrite rolling method realizes continuous non-stop production under the condition that an existing production line is basically unchanged. Meanwhile, through the cooperative use of the induction heating and the cooling channel, full continuous non-stop flexible rolling can be realized, the yield is further improved. In addition, during andafter the process of dynamic variable procedure of the endless rolling, lower heating temperature is adopted by the induction heating, the temperature rise of a roll can further be reduced, thus thefatigue cracking and fracture of the roll caused by thermal stress are reduced, the roll abrasion is reduced and the surface quality of endless rolling products is improved, the heating energy consumption of enterprises can be greatly reduced, and an important role in energy conservation, environmental protection and improving economic benefits of the enterprises is played.
