[0025] Example 1

[0026] See Figure 1 to Figure 3 As shown, the high-throughput ceramic micro-reactor provided by the present invention includes a reactor ceramic body 1, a rubber gasket 2, a ceramic cover plate 3. The reactor ceramic body 1 and ceramic cover plate 3 pass ceramic light It is formed by curing, printing and sintering, and the sintering temperature is 900°C to 1750°C; the shape and size of the reactor ceramic body 1, the rubber gasket 2, and the ceramic cover plate 3 match; the reactor ceramic body 1 There are 4 to 225 reaction micropores 11 distributed in an array with a spacing of 2 to 5 mm. Each reaction micropore has a diameter of 5 mm to 10 mm and a depth of 10 mm to 40 mm. The reaction micropores 11 can be subjected to high temperature, high pressure or high pressure. The chemical reaction test under corrosive conditions, and different chemical reaction tests can be performed in different reaction micropores 11; the rubber gasket 2 has a thickness of 1 to 4...

[0029] Example 2

[0030] The first step is to use UG software to design a 3*3 9-hole micro-reactor model. Each hole has a depth of 20mm, a hole diameter of 10mm, a hole wall thickness of 2.8mm, and a hole spacing of 3mm. The corresponding rubber gasket has a protrusion diameter of 10mm, a protrusion height of 2mm, and a gasket thickness of 2mm. The thickness of the ceramic cover is 3mm, and it is fixed with 8 M2 screws, the screw length is 16mm. The second step is to export the model to STL format, and then import it into a DLP ceramic light-curing printer for printing after slicing. The printing material is zirconia slurry. The printed green body is like Figure 5 Shown. In the third step, the green zirconia microreactor is placed in a high-temperature furnace for degreasing and sintering, with a maximum temperature of 1450 degrees, and holding for 2 hours. The fourth step is to prepare 10mL of Ca(NO3)2·4H2O solution (0.1mol / L), add quantitative (NH4)2HPO4 (to ensure that the...

Abstract

The invention discloses a high-flux ceramic micro-reactor. The high-flux ceramic micro-reactor comprises a reactor ceramic main body, a rubber gasket and a ceramic cover plate, and the reactor ceramicmain body and the ceramic cover plate are formed by photocuring printing of ceramic, degreasing and sintering; and the reactor ceramic main body is provided with a plurality of reaction micro-pores,a chemical reaction test under high-temperature and high-pressure or strong-corrosion conditions can be carried out in the reaction micro-pores, the rubber gasket is laid on the top surface of the reactor ceramic main body, bulges in one-to-one correspondence with the reaction micro-pores are formed on the rubber gasket and are used for plugging openings of the reaction micro-pores to ensure the sealing degree of the chemical reaction in the reaction micro-pores and avoid the outward leakage of a reaction liquid in the reaction micro-pores, and the ceramic cover plate covers and presses the rubber gasket and is fixedly connected with the reactor ceramic main body through screws. The high-flux ceramic micro-reactor has the advantages of good high temperature resistance, good acid and alkalicorrosion resistance, good wear resistance, high flux and the like, and is especially suitable for researching micro-reactions at a high temperature, such as a hydrothermal reaction.

Description

technical field [0001] The invention relates to the technical field of ceramic printing and microfluidic synthesis, in particular to a high-throughput ceramic microreactor. Background technique [0002] Microfluidics is the technology and science of manipulating nanoliter to picoliter volume fluids in micron-scale structures. It is a new interdisciplinary subject that has risen rapidly in the past 10 years. Compared with chemical reactions carried out in conventional reaction vessels (flasks or reactors), microfluidic reactors have the characteristics of short intermolecular diffusion distances, large specific surface areas, fast heat and mass transfer rates, and less dosage. At the same time, the high-throughput, large-scale, and parallel characteristics of microfluidic reactors make the integration and parallel operation of multiple or a large number of microreactors possible, thereby improving the efficiency of synthesizing new substances and screening new drugs, and grea...
