The invention provides a core-shell quantum dot, and a preparation method and an application thereof. The preparation method comprises the following steps: 1, mixing a quantum dot core solution with asecond cationic precursor solution to form a second system; 2, adding a second cationic precursor solution and second fatty acid into the second system in batches at 210-280 DEG C when the average diameter of quantum dot cores in the quantum dot core solution is more than or equal to 2 times the minimum Bohr diameter of holes or electrons of a quantum dot core composition material to carry out epitaxial growth in order to obtain the core-shell quantum dot; or adding the second cationic precursor solution into the second system in batches at 210-280 DEG C when the average diameter of the quantum dot cores in the quantum dot core solution is less than 2 times the minimum Bohr diameter to carry out epitaxial growth, and adding the second fatty acid into the second system in batches after 0.5to 2 layers of a monolayer shell grow on every quantum dot core.

The present invention is the recipe of three component polyurethane resin for insole. The polyurethane resin includes one component A of active hydrogen-containing mixture comprising long chain polyol polymer, chain expanding agent, cross-linking agent, surfactant, foaming agent and other assistants; one component B comprising polyester or polyether modified MDI pre-polymer; and one component C or catalyst component of glycol solution of triethylidene diamine. The polyurethane resin has density as low as 0.25-0.30 g / cu cm, capacity of making the product firm and good in appearance, and other advantages.

The invention relates to a rice noodle preparation method of a household rice noodle machine and the household rice noodle machine. The rice noodles preparation method of the household rice noodle machine comprises the following steps: a feeding stage, namely driving a screw rod to rotate by a drive system and feeding raw materials into an extrusion grinding cavity by the screw rod; a curing and noodle-extruding stage, namely driving the screw rod to rotate by the drive system, grinding the raw materials by the screw rod, mixing, simultaneously curing the raw materials, and extruding into rice noodles from the ground, crushed, mixed and cured raw materials through a molding die head; and a once warming process, namely heating a extrusion crushing cavity by a heating device before the curing and noodle-extruding stage, so that the temperature of the extrusion crushing cavity ascends to T1, and the range of T1 is 80-110 DEG C, and feeding the rice material into the extrusion grinding cavity for curing after the once warming process is additionally added in the rice noodle preparation process, so that the hardness of the rice material is reduced, and the crushing of the rice material by virtue of a crushing, extruding and molding system in the curing and noodle-extruding stage is facilitated, and forming of the rice noodles are facilitated.

The invention discloses a preparation method of a compound microorganism bacterium agent for sludge treatment. The compound microorganism bacterium agent is prepared by mixing escherichia coli, bacillus, sulfur-oxidizing bacteria, actinomyces, nitrifying bacteria and lactic acid bacteria; meanwhile, the invention provides the preparation method of the compound microorganism bacterium agent for the sludge treatment. According to the preparation method disclosed by the invention, the adaptation activity of a compound bacterium colony to temperature can be improved through adding adamantanamine and diethylmalonylurea; the adding amount of the bacterium colony can be reduced and the composting efficiency also can be improved; the compound microorganism bacterium agent disclosed by the invention can be used for effectively killing harmful microorganisms and pathogens in sludge through composting fermentation; meanwhile, a large amount of evaporation of moisture is accelerated and the problem of treating residual sludge in a wastewater treatment system is solved so that the dehydration efficiency of the sludge is improved.

The invention relates to the field of feed, and especially discloses nursery piglet feed for producing antibiotic-free pork and a preparation method thereof. The nursery piglet feed includes a cured corn-soybean meal mixture, half-dried fermented biological feed, coconut oil powder, steam fish meal, intestinal membrane protein, expanded soybean, sucrose, vitamin compound premix, low-content coatedtrace element composite premix, amino acid, mountain flour, calcium hydrophosphate, calcium formate, sodium chloride, a mucosal barrier agent, an intestinal astringent, a natural antibacterial and antiviral complex, frankincense, a sweetening agent, choline chloride, tea polyphenols and phytase. The nursery piglet feed can promote piglets to eat, improve production performance, prevent diarrhea and prevent and resist diseases, and is antibiotic-free, efficient, green and safe; and therefore, the nursery piglet feed is antibiotic-free, clean and ecological and can be used for producing antibiotic-free pork.
