Photocuring aluminum oxide ceramic paste and atomization cavity integrated forming method thereof
The invention discloses a photocuring aluminum oxide ceramic paste and an atomization cavity integrated forming method thereof. The paste comprises ceramic powder, stearic acid powder, premixed liquid and a dispersing agent. The forming method comprises the following steps: printing the photo-cured aluminum oxide ceramic paste into an atomization cavity structure, and then performing degreasing and sintering; and adjusting atomization cavity structure parameters, printing process parameters and degreasing sintering process parameters. The atomization cavity structure parameters comprise the overall wall thickness and the connecting fillet radius of an atomization cavity; the printing process parameters comprise a printing support gap, printing laser power, layer thickness and curing depth; and the degreasing sintering process parameters comprise heating rate, powder burying amount, pre-sintering temperature, degreasing temperature point and heat preservation time. By optimizing the components of the photocuring aluminum oxide ceramic paste, the structure of the atomization cavity and the post-treatment process, the performance (strength, corrosion resistance and the like) of the aluminum oxide atomization cavity is improved, the cracking deformation of the atomization cavity in the preparation process is reduced, and the preparation yield of the atomization cavity is further improved.
