Background
Gypsum slip casting, also known as cast molding, is a method of preparing ceramic powder into fluid slurry based on the physical property that a porous gypsum mold can absorb moisture, then injecting the fluid slurry into the porous mold (mainly a gypsum mold), forming a uniform slurry layer with a certain thickness after the moisture is absorbed by the mold (gypsum), and forming a blank with a certain strength in the dehydration and drying processes, which is called slip casting. The completion process can be divided into three stages: after the slurry is injected into the mould, water in the slurry is absorbed under the action of capillary force of the plaster mould, the water in the slurry close to the mould wall is firstly absorbed, and particles in the slurry begin to approach to form an initial thin slurry layer. The moisture is further absorbed, the diffusion power of the moisture is the pressure difference and the concentration difference of the moisture, the thin mud layer becomes thicker gradually, the moisture in the mud layer diffuses outwards, and when the thickness of the mud layer reaches the thickness of the injected piece, a young blank is formed. And (4) continuously absorbing the moisture by the gypsum mold, enabling the blank to shrink, enabling the moisture on the surface to evaporate, and demolding after the blank is dried to form a green body with certain strength to finish grouting forming. However, whatever material is used to make the molding, it is necessary that the material has water-absorbing properties and is subjected to complicated processing. This brings much invariance to the job and also increases the production cost.
