Description
Technical Field
The invention relates to the technical field of flat ceramic preparation, in particular to a phase inversion casting machine for preparing a ceramic flat green body and a method for preparing the ceramic flat green body by using the same.
Background
The phase inversion process starts in the sixties of the twentieth century and comprises at least 3 materials: polymers, solvents, and non-solvents. Wherein the polymer is soluble in the solvent and insoluble in the non-solvent, the solvent and the non-solvent being mutually soluble. When the polymer solution (wet film) is immersed in the coagulation bath (non-solvent), the solvent and non-solvent in the wet film will undergo interdiffusion through the interface where the wet film is in contact with the non-solvent, and when the diffusion exchange reaches a certain degree, the wet film becomes a thermodynamically unstable system, causing phase separation to occur. After the wet film system phase separation, solvent and non-solvent exchange proceeds, film pore coagulation occurs, phase-to-phase flow and polymer curing film formation occurs. In the phase transition process, an asymmetric structure containing a finger pore layer and a sponge pore layer is formed due to the rapid exchange of the solvent and the non-solvent. This particular structure makes the phase inversion method widely applicable in the field of ceramic film green body preparation.
At present, the phase inversion molding mode mainly comprises extrusion molding and casting molding. The phase inversion tape casting method is to coat the organic slurry containing ceramics on a flat substrate, then manually transfer the slurry into a flocculating agent, and then cut the slurry after solidification, and the whole preparation process is complex and has poor controllability. The existing industrial casting machine is widely applied to the preparation of flat ceramic green bodies, but the whole casting table surface is basically plane or a cast film belt cannot be automatically transferred into a flocculating agent, so that the requirement of efficient phase inversion casting production cannot be met.
