Additive for smelting aluminium alloy and preparation method and application method thereof

The invention relates to an additive for smelting aluminium alloy and a preparation method and an application method thereof, relating to the technical field of nonferrous alloy manufacturing with a special additive. The additive is composed of metal powder, cosolvent, heat-generating agent, detonating agent and moisture proof agent. The preparation method comprises the following steps: raw materials comprising the following by mass percentage, 70-81.5% of metal powder, 15-20% of cosolvent, 2-5% of heat-generating agent, 1-3% of detonating agent and 0.5-2% of moisture proof agent, are fully mixed evenly into compound powder with a ball mill, and the mixture is put into a mould, and is performed with cold pressing by a hydraulic pressure machine so as to obtain the additive for smelting aluminium alloy. The application method of the invention comprises the following steps: a graphite crucible filled with a pure aluminium pig is arranged in a resistance furnace to be heated until the aluminium pig is melted into aluminium liquid, and then the additive is added to react with the aluminium liquid so as to obtain aluminium alloy. Under the condition that the quality of aluminium alloy is not lowered, the additive solves the problems of high dissolving temperature, low absorptivity and unstable absorptivity of the additive.

Control device for fermenter

The present invention allows biomass and/or biomass-produced components to be obtained at high yields by executing numeric simulation of flow to reasonably identify the running conditions suitable for a fermenter. The control device according to the present invention comprises an input means for entering measured data from a measurement means, which measures nutrient components, the concentrations of oxygen, carbon dioxide, and biomass in a culture medium; a computation means for calculating nutrient components uptake rate, oxygen uptake rate and carbon dioxide exhaust rate per unit amount of biomass from the measured data entered at the aforementioned input means, as well as volumetric mass transfer coefficient kLa from turbulent energy k and a turbulent energy dissipation rate e, both of which are calculated by a transport equation, as well as a diffusion coefficient D, followed by calculating the concentrations of the nutrient components, dissolved oxygen, and dissolved carbon dioxide in any area in the fermenter using an algorithm to numerically integrate a differential equation describing variations in medium components over time from the calculated nutrient components uptake rate, the calculated oxygen uptake rate, the calculated carbon dioxide exhaust rate, and the calculated volumetric mass transfer coefficient kLa; and a display means for displaying concentration distributions of the nutrient components, dissolved oxygen, and dissolved carbon dioxide in the fermenter based on the concentrations of the nutrient components, dissolved oxygen, and carbon dioxide in any area of the fermenter calculated at aforementioned computation means.

Nano drug carrier particles for improving bioavailability of rapamycin and preparation method thereof

The invention discloses nano drug carrier particles for improving the bioavailability of rapamycin and a preparation method thereof, so as to carry out a drug effect optimization. The nano drug carrier particles are prepared in the following steps that according to the principle of an emulsion solvent evaporation method, a determined amount of PEG-PLGA and rapamycin are respectively dissolved in acetone; after being mixed uniformly, the PEG-PLGA, the rapamycin and the acetone are slowly added into water to be stirred by magnetic force; after a certain period of time, the obtained liquid is ultrasonically homogenated, and organic phase is removed in a vacuum dryer; the obtained water phase removes free medicine in a centrifugal tube; and then an ultrafiltration tube is used for concentration, and nano particles are obtained after freezing and drying. The method has the advantages of convenience in operation, simplicity and feasibility, good repeatability and the like. The prepared nano drug carrier particles can improve the utilization rate of the medicine by improving the absorptivity of the medicine and prolonging the cycling time in a human body. Meanwhile, the nano particles which are prepared through the method have good biocompatibility, and surface active groups can further modify ligands or targeted groups.
