Embodiment

[0030] Embodiment: first process the track disk, the track disk is made of stainless steel, the length is 20m, and the thickness is 10mm. There are 9 semicircular tracks, the diameter of the semicircular track is 5mm, and the distance between two adjacent semicircular tracks is 5mm. mm, carry out sandblasting treatment on the surface of the orbital disk, the surface roughness of the orbital disk after sandblasting is less than 1.6μm, and then paste a heating tape on the surface of the orbital disk and spray hydrophobic paint, so that the heating belt can heat the orbital disk at 80°C 3h, drying the hydrophobic coating.

[0031] Then prepare raw materials, weigh ZrO with an average particle size of 0.1 μm 2 Powder 800g, and according to the mass percentage, weigh the ZrO 2 The total mass ratio of the powder is 2.3% of acrylamide, 0.25% of N-N'methylenebisacrylamide, 1.2% of ammonium polycarboxylate, 0.45% of ammonium persulfate and 0.17% of tetramethylethylenediamine ; Add acry...

Abstract

A method for directly titrating and forming ceramic microspheres through gel casting of a track comprises the following steps: firstly, processing a track disc with a plurality of semicircular tracks, pasting a heating belt on the surface of one side, opposite to the semicircular tracks, of the track disc, spraying hydrophobic coating on the surfaces of the semicircular tracks, and drying the hydrophobic coating through the heating belt; then preparing ceramic slurry; and finally, carrying out titration forming, obliquely placing the track disc, enabling an included angle of 10-15 degrees to be formed between the track disc and the horizontal direction, enabling the semicircular tracks to face upwards, placing the titration disc at the top end of the track disc, enabling a plurality of titration needle cylinders of the titration disc to be respectively aligned with the top ends of the semicircular tracks, and then heating the track disc at 120-150 DEG C by using the heating belt, and then injecting the ceramic slurry into the titration disc, so that ceramic slurry liquid drops roll downwards on the semicircular track and are heated and cured into ceramic microsphere blanks. The preparation method has the advantages of low process cost, few procedures and easiness in realization of automatic production, and the prepared ceramic microspheres are high in sphericity and uniform in internal structure.

Description

technical field [0001] The invention relates to the field of forming ceramic microspheres, in particular to a method for directly titrating and forming ceramic microspheres through orbital gel injection molding. Background technique [0002] Ceramic microspheres refer to spherical structures or functional materials with a diameter of less than 1mm, usually 0.1mm~1mm. The commonly used types of ceramic microspheres include grinding media such as ZrO2 ceramic microspheres, which are used for grinding powder in sand mills; functional types For example, Gd2O2S, lithium ceramics, ZrN and other ceramic microspheres are used for new cold storage materials in G-M ultra-low temperature refrigerators and tritium-producing cladding functional materials and inert matrix materials in the nuclear industry. The existing ceramic microsphere molding technology mainly includes rolling method and conventional titration method. Among them, the rolling method requires many processes such as cor...
