[0021] The embodiments of the present application provide a method of making a ceramic piece, Figure 1 A flowchart of an embodiment of a method of making a ceramic piece of the present application, the method of making a ceramic piece comprising steps S110 to S130.

[0022] In step S110, a slurry brush is attached to a nylon mesh filter cloth, wherein the nylon mesh filter cloth is a 120-mesh nylon mesh filter cloth.

[0023] In step S120, the surface on which the nylon mesh filter cloth is arranged is kept in a longitudinal arrangement state, so that the slurry is dried to obtain a filter cloth assembly.

[0024] In step S130, the filter cloth assembly is fired so that the filter cloth assembly is converted into a ceramic piece.

[0025] In the embodiment, the slurry for making the ceramic piece includes the following raw materials: kaolin and water in a mass ratio of 3:2; water glass accounting for 0.3% of the total mass of the raw materials; sodium humate accounting for 0.3% of the total mass of the raw materials; defoaming agent accounting for 0.05% of the total mass of the raw materials; dispersant accounting for 0.1% of the total mass of the raw materials; suspending agent accounting for 0.5% of the total mass of the raw materials; paper pulp accounting for 0.2% of the total mass of the raw materials.

[0026] According to the above-mentioned slurry for making the ceramic piece, the slurry includes the following raw materials: kaolin and water in a mass ratio of 3:2; water glass accounting for 0.3% of the total mass of the raw materials; sodium humate accounting for 0.3% of the total mass of the raw materials; defoaming agent accounting for 0.05% of the total mass of the raw materials; dispersant accounting for 0.1% of the total mass of the raw materials; suspending agent accounting for 0.5% of the total mass of the raw materials; and paper pulp accounting for 0.2% of the total mass of the raw materials. The slurry is formed by mixing the above-mentioned raw materials.

[0027] The water glass and the sodium humate as additives can affect the dynamic viscosity of the slurry, and after being applied to the nylon mesh filter cloth, the weight causes pulling, thereby affecting the thickness of the ceramic piece. The water glass accounting for 0.3% of the total mass of the raw materials and the sodium humate accounting for 0.3% of the total mass of the raw materials as additives can make the slurry have good gelation, which can make the slurry of kaolin and water in a mass ratio of 3:2 have the effects of flowing and pulling, while ensuring the viscosity and concentration of the slurry, so that the ceramic piece can be as thin as 1 mm, and the thickness of the ceramic piece can be stably ensured to be below 2 mm.

[0028] The ratio of the dispersing agent and the suspending agent in the slurry can affect the uniformity of the particles in the slurry, and the ratio of the defoaming agent, the dispersing agent and the suspending agent can affect the defoaming effect. When the dispersing agent and the suspending agent in the slurry increase, the uniformity and the suspending property increase. For the slurry with the mass ratio of kaolin and water being 3:2, when the dispersing agent increases to 0.1% of the total mass of the raw materials and the suspending agent increases to 0.5% of the total mass of the raw materials, the uniformity and the suspending property meet the requirements for manufacturing ceramic pieces with a thickness of less than 2 mm, and the uniformity and the suspending property have reached a good effect. When the dispersing agent and the suspending agent continue to increase, the uniformity and the suspending property do not obviously increase. When the mass ratio of the defoaming agent, the dispersing agent and the suspending agent is 1:2:10, for the slurry with the mass ratio of kaolin and water being 3:2, the observable foam has been eliminated. Therefore, in the embodiments of the present application, the slurry has 0.05% of the total mass of the raw materials of the defoaming agent, 0.1% of the total mass of the raw materials of the dispersing agent and 0.5% of the total mass of the raw materials of the suspending agent, which can make the slurry and the pulp particles more uniform, and ensure the surface flatness of the manufactured ceramic pieces.

[0029] When the ceramic piece is thin, it is prone to cracking. In the embodiments of the present application, the slurry has 0.2% of the total mass of the raw materials of the pulp, which can solve the cracking problem. When the slurry has 0.2% of the total mass of the raw materials of the pulp, the pulling degree between the particles in the slurry can be enhanced, thereby enhancing the strength of the manufactured ceramic piece, and the problem of the thin ceramic piece being prone to cracking can be well solved. When the proportion of the pulp is 0.2% of the total mass of the raw materials, the problem of the manufactured ceramic piece being prone to cracking can be solved, and the manufactured ceramic piece still has better hardness, thereby avoiding the problem of the ceramic piece being too brittle and fragile.

[0030] When the slurry meets the above raw material ratio, the slurry has higher fluidity, lower viscosity and higher stability, thereby meeting the needs of manufacturing thinner ceramic pieces, and can be suitable for manufacturing thinner ceramic pieces.

[0031] In the embodiments, the nylon mesh filter cloth is a 120-mesh nylon mesh filter cloth, which can better ensure that the slurry is fully adsorbed and adhered in the gaps of the nylon mesh filter cloth, and further ensure that the slurry is not easy to demold before firing. In addition, during the drying process of the slurry, the surface on which the nylon mesh filter cloth is arranged is kept in a longitudinal arrangement state, the slurry can fully flow, and the thickness of the slurry is further reduced in the flowing and pulling, thereby further reducing the thickness of the obtained ceramic piece.

[0032] In the embodiments, the water glass is R2O·nSiO2, wherein R2O is an alkali metal oxide; and the molecular formula of the sodium humate is C9H8Na2O4.

[0033] The defoaming agent, the dispersing agent and the suspending agent can use the defoaming agent, the dispersing agent and the suspending agent known in the art for ceramic manufacturing processes.

[0034] Preferably, in the present embodiment, the defoaming agent has a molecular formula of C31H39N4O10, i.e. GP330, the dispersant has a molecular formula of C18H29NaO3S, i.e. 3-dodecylbenzenesulfonic acid sodium salt, and the suspending agent has a molecular formula of C11H15N3O, i.e. high-molecular polyvinylpyrrolidone.

[0035] In some embodiments, the clay paste for making the ceramic piece further comprises 10% of the mass of the kaolin of a medium-temperature transparent glaze powder. The water absorption of the ceramic piece can represent the vitrification degree thereof. When the proportion of the medium-temperature transparent glaze powder is too high, the water absorption is reduced, the vitrification degree of the surface of the ceramic piece is higher, and the original texture of the ceramic piece is significantly changed, so that the light reflection degree of the surface of the ceramic piece is uncontrollable. In the above embodiments, the clay paste further comprises 10% of the mass of the kaolin of a medium-temperature transparent glaze powder. The medium-temperature transparent glaze powder at the above proportion can protect the ceramic surface when the clay paste forms the ceramic piece, enhance the durability of the ceramic piece, and at the same time, can ensure that the ceramic piece retains the original texture to a greater extent, facilitating more stable post-processing in the later stage.

[0036] In some embodiments, the step S110 of applying the clay paste to the nylon mesh filter cloth comprises: tensioning the nylon mesh filter cloth in the frame; and applying the clay paste to the nylon mesh filter cloth when the nylon mesh filter cloth is in a suspended state. The frame is for example a wooden frame, which is enclosed in a closed shape and has a receiving space in the middle. The nylon mesh filter cloth can be tightly arranged in the receiving space. In one example, the clay paste is applied to the nylon mesh filter cloth by using a brush to dip the clay paste when the nylon mesh filter cloth is in a suspended state.

[0037] In some embodiments, the step S120 of keeping the surface on which the nylon mesh filter cloth is arranged in a longitudinal arrangement state so that the clay paste is dried to obtain the filter cloth assembly comprises: standing the frame upright and leaving it stationary so that the surface on which the nylon mesh filter cloth is arranged is in a longitudinal arrangement state, and after the clay paste is dried, the nylon mesh filter cloth together with the dried clay paste attached to the surface forms the filter cloth assembly; and detaching the filter cloth assembly from the frame.

[0038] In some embodiments, before the step S120, the method for making the ceramic piece further comprises: removing the clay paste exuded from the back of the nylon mesh filter cloth.

[0039] In some embodiments, before the step S110, the method for making the ceramic piece further comprises: soaking the paper pulp raw material for a preset time period, crushing the paper pulp raw material to obtain crushed material, and drying the crushed material to obtain the paper pulp used as the raw material of the clay paste. In some embodiments, the preset time period is 1.5 to 4 hours. In one example, the paper pulp raw material is soaked for 2 hours, crushed to obtain the crushed material, and then left to dry to obtain the paper pulp used as the raw material of the clay paste. Through the above processing, the paper pulp can be uniformly distributed in the formed clay paste, and the structural strength of the obtained ceramic piece can be stably ensured.

[0040] In the present embodiment, the filter cloth assembly is fired in step S130, so that the filter cloth assembly is converted into a ceramic piece. In one example, the filter cloth assembly is placed in a kiln for firing at 1270°C.

[0041] Figure 2 A flowchart of another embodiment of the method for manufacturing a ceramic piece of the present application, in another embodiment, the method for manufacturing a ceramic piece comprises steps S210 to S260.

[0042] In step S210, the slurry is applied to a nylon mesh filter cloth, wherein the nylon mesh filter cloth is a 120-mesh nylon mesh filter cloth.

[0043] In step S220, the surface on which the nylon mesh filter cloth is kept in a longitudinal arrangement, so that the slurry is dried to obtain a filter cloth assembly.

[0044] In step S230, the filter cloth assembly is fired, so that the filter cloth assembly is converted into a ceramic piece.

[0045] In the present embodiment, the slurry for manufacturing a ceramic piece comprises the following raw materials: Kaolin and water in a mass ratio of 3:2; Water glass accounting for 0.3% of the total mass of the raw materials; Sodium humate accounting for 0.3% of the total mass of the raw materials; Defoaming agent accounting for 0.05% of the total mass of the raw materials; Dispersing agent accounting for 0.1% of the total mass of the raw materials; Suspending agent accounting for 0.5% of the total mass of the raw materials; Paper pulp accounting for 0.2% of the total mass of the raw materials.

[0046] In some embodiments, the slurry for manufacturing a ceramic piece further comprises: medium-temperature transparent glaze powder accounting for 10% of the mass of the kaolin.

[0047] In step S240, the edges of the ceramic piece are polished. In one example, a micro-polishing tool, such as a super-fine grinding wheel, is used to finely polish the edges of the ceramic piece. Without affecting the overall thickness of the ceramic piece, the edges of the ceramic piece are polished to be smoother and more rounded, reducing the generation of micro-cracks at the edges of the ceramic piece.

[0048] In step S250, based on the size and shape of at least part of the edges of the ceramic piece, a flexible frame matching at least part of the edges of the ceramic piece is manufactured, and one side of the flexible frame is provided with a mounting groove.

[0049] In step S260, the flexible frame is mounted to at least part of the edges of the ceramic piece, wherein the edges of the ceramic piece are inserted into the mounting groove.

[0050] Figure 3 ,Figure 4 FIG. 13 is a perspective view of a ceramic piece according to an embodiment of the present application, and FIG. 14 is a partial cross-sectional view of the ceramic piece. In one example, in step S250, a flexible frame 120 is made to match a portion of the edges of the ceramic piece 110. For example, the ceramic piece 110 is polygonal, and the flexible frame 120 matches a portion of the edges of the ceramic piece 110.

[0051] In some embodiments, the flexible frame 120 is made of elastic material, and in the unstressed state, the width of the slot of the mounting slot 121 is less than the thickness of the edge of the ceramic piece 110. In some embodiments, the flexible frame 120 is made of elastic silicone material.

[0052] Because the ceramic piece 110 obtained according to the embodiments of the present application is very thin, the use of traditional adhesives or mechanical fixing methods will cause additional stress on the ceramic piece, increasing the risk of damage to the ceramic piece. In the above embodiments, the edges of the ceramic piece 110 are polished first, and then the flexible frame 120 is mounted at least a portion of the edges of the ceramic piece. The flexible frame 120 is provided with a mounting slot 121 capable of accommodating at least a portion of the edges of the ceramic piece, thereby providing protection to at least a portion of the edges of the ceramic piece. The flexibility of the elastic material can absorb stress during installation and prevent the ceramic piece from being directly impacted, thereby greatly reducing the risk of damage to the ceramic piece. In the unstressed state, the width of the slot of the mounting slot 121 is less than the thickness of the edge of the ceramic piece 110. After the edge of the ceramic piece 110 is inserted into the mounting slot 121, the slot of the mounting slot 121 is tightly fitted with the ceramic piece 110, so that the inside of the mounting slot 121 is sealed, forming a slight negative pressure environment, improving the stability of the connection between the ceramic piece 110 and the flexible frame 120, and no longer needing adhesives to fix the ceramic piece, thereby reducing the additional stress on the ceramic piece.

[0053] Figure 5 FIG. 15 is a flowchart of another embodiment of a method for making a ceramic piece according to the present application. In another embodiment, the method for making a ceramic piece includes steps S310 to S380.

[0054] In step S310, a mud brush is attached to a nylon mesh filter cloth, wherein the nylon mesh filter cloth is a 120-mesh nylon mesh filter cloth.

[0055] In step S320, the surface on which the nylon mesh filter cloth is arranged is kept in a longitudinal arrangement state so that the mud is dried, and a filter cloth assembly is obtained.

[0056] In step S330, the filter cloth assembly is fired so that the filter cloth assembly is converted into a ceramic piece.

[0057] In this embodiment, the mud used to make the ceramic piece includes the following raw materials: Kaolin and water in a mass ratio of 3:2; 0.3% of sodium silicate by total mass of raw materials; 0.3% of sodium humate by total mass of raw materials; 0.05% of defoaming agent by total mass of raw materials; 0.1% of dispersing agent by total mass of raw materials; 0.5% of suspending agent by total mass of raw materials; 0.2% of paper pulp by total mass of raw materials.

[0058] In some embodiments, the clay for making the ceramic piece further comprises: 10% of medium temperature transparent glaze powder by mass of the kaolin.

[0059] In step S340, the edge of the ceramic piece is polished.

[0060] In step S350, a flexible frame matching the at least part of the edge of the ceramic piece is made based on the size and shape of the at least part of the edge of the ceramic piece, and one side of the flexible frame is provided with a mounting slot.

[0061] In step S360, the flexible frame is mounted on the at least part of the edge of the ceramic piece, and the edge of the ceramic piece is inserted into the mounting slot.

[0062] Figure 6 FIG. 1 is a perspective view of a ceramic piece in another embodiment of the method for making the ceramic piece. In this embodiment, the flexible frame matches all edges of the ceramic piece, the flexible frame is in a closed shape around the edges of the ceramic piece, and the mounting slot is arranged on the inner side of the flexible frame. For example, the ceramic piece is circular or elliptical, and the flexible frame is in a ring structure around the edges of the ceramic piece. Therefore, in step S360, the flexible frame is mounted on all edges of the ceramic piece, and the edges of the ceramic piece are inserted into the mounting slot.

[0063] In some embodiments, the flexible frame is made of elastic material, and in the state without force, the width of the slot opening of the mounting slot is smaller than the thickness of the edge of the ceramic piece. In some embodiments, the flexible frame is made of elastic silica gel material.

[0064] As shown in FIG. 1, the flexible frame 120 is arranged on the edge of the ceramic piece 100, and the edge of the ceramic piece 100 is inserted into the mounting slot of the flexible frame 120. Figure 6 In this embodiment, the outer wall of the flexible frame 120 is provided with a through hole 122 communicating with the mounting slot. The number of the through hole 122 can be single or multiple, and when the number of the through hole 122 is multiple, the through holes 122 can be uniformly distributed along the extension direction of the flexible frame 120.

[0065] In this embodiment, after step S360, the method for making the ceramic piece further comprises steps S370 and S380.

[0066] In step S370, the vacuumizing device is communicated with the through hole 122 and the mounting slot is vacuumized.

[0067] In step S380, after the vacuumizing process is completed, the through hole 122 is sealed.

[0068] In some embodiments, when the mounting groove is subjected to the vacuumizing process, the vacuum degree in the mounting groove is detected by the vacuumizing device to reach a preset value, so that excessive vacuumizing is avoided to generate greater pressure on the edge of the ceramic sheet.

[0069] In the above embodiments, the outer wall of the flexible frame 120 is provided with the through hole 122 communicating with the mounting groove. After the assembly of the flexible frame 120 and the ceramic piece is completed, the mounting groove is subjected to the vacuumizing process through the through hole 122, so that the stability of the connection between the ceramic piece 110 and the flexible frame 120 is further improved, and the adhesive is no longer needed to fix the ceramic sheet 110.

[0070] According to the method for manufacturing the ceramic piece in the above embodiments, the thickness of the manufactured ceramic piece is extremely thin. For the ceramic piece with extremely thin thickness, there is no suitable coloring method in the related art, so that the artistic creation of the ceramic piece is limited.

[0072] Figure 7 A flowchart of another embodiment of the method for manufacturing the ceramic piece of the present application is shown in the figure. In this embodiment, the method for manufacturing the ceramic piece includes steps S410 to S460.

[0073] In step S410, the slurry brush is attached to the nylon mesh filter cloth, wherein the nylon mesh filter cloth is a 120-mesh nylon mesh filter cloth.

[0074] In step S420, the surface on which the nylon mesh filter cloth is arranged is kept in a longitudinal arrangement state, so that the slurry is dried to obtain a filter cloth assembly.

[0075] In step S430, the filter cloth assembly is fired to convert the filter cloth assembly into a ceramic piece.

[0076] In this embodiment, the slurry for manufacturing the ceramic piece includes the following raw materials: kaolin and water in a mass ratio of 3:2; water glass accounting for 0.3% of the total mass of the raw materials; 0.3% of humic acid sodium based on the total mass of raw materials; 0.05% of defoaming agent based on the total mass of raw materials; 0.1% of dispersing agent based on the total mass of raw materials; 0.5% of suspending agent based on the total mass of raw materials; 0.2% of paper pulp based on the total mass of raw materials.

[0077] In some embodiments, the slip for making the ceramic piece further comprises: 10% of medium-temperature transparent glaze powder based on the mass of the kaolin.

[0078] In step S440, the color powder of overglaze new color is ground after being mixed with frankincense oil to obtain a first mixture.

[0079] In step S450, the first mixture is sprayed on the ceramic piece.

[0080] In step S460, the ceramic piece is shaded by banana water.

[0081] In one example, the color powder of overglaze new color is ground after being mixed with frankincense oil to obtain a first mixture, the first mixture is filled into a spray gun, the ceramic piece is colored by spraying through the spray gun, and then the ceramic piece is shaded by banana water, thereby realizing the decoration process of the ultra-thin ceramic piece.

[0082] In the above embodiments, the color powder of overglaze new color can be fully adsorbed on the surface of the ceramic piece, and the ceramic piece has richer color tone and levelness on the basis of basically not affecting the thickness of the ceramic piece. According to needs, the ultra-thin ceramic piece can have good light transmission and color transmission, and the flexibility of creation on the ultra-thin ceramic piece is improved.

[0083] According to the method for manufacturing the ceramic piece, the mud for manufacturing the ceramic piece comprises the following raw materials: kaolin and water in a mass ratio of 3:2; water glass accounting for 0.3% of the total mass of the raw materials; sodium humate accounting for 0.3% of the total mass of the raw materials; defoaming agent accounting for 0.05% of the total mass of the raw materials; dispersing agent accounting for 0.1% of the total mass of the raw materials; suspending agent accounting for 0.5% of the total mass of the raw materials; and paper pulp accounting for 0.2% of the total mass of the raw materials. The mud is formed by mixing the above raw materials. The water glass accounting for 0.3% of the total mass of the raw materials and the sodium humate accounting for 0.3% of the total mass of the raw materials serve as additives, so that the mud has good gelation, and the mud with the kaolin and water in a mass ratio of 3:2 has the effects of flowing and pulling, and the viscosity and concentration of the mud are ensured. When the mud contains the paper pulp accounting for 0.2% of the total mass of the raw materials, the pulling degree between the particles in the mud is enhanced, so that the strength of the ceramic piece manufactured is enhanced, and the problem that the ceramic piece is prone to cracking when the ceramic piece is thin is solved. When the mud contains the defoaming agent accounting for 0.05% of the total mass of the raw materials, the dispersing agent accounting for 0.1% of the total mass of the raw materials, and the suspending agent accounting for 0.5% of the total mass of the raw materials, the mud and the paper pulp particles are more uniform, and the surface flatness of the ceramic piece manufactured is ensured. When the mud satisfies the above raw material ratio, the mud has higher fluidity, lower viscosity and higher stability, so that the demand for manufacturing thin ceramic pieces is met, and the mud can be applied to the manufacturing of thinner ceramic pieces.

[0084] According to the method for manufacturing the ceramic piece, the mass ratio of the kaolin and water is 3:2, and the mud contains the water glass accounting for 0.3% of the total mass of the raw materials and the sodium humate accounting for 0.3% of the total mass of the raw materials. The electrolytes in the water glass and the sodium humate have better gelation on the mud, so that the mud with the kaolin and water in a mass ratio of 3:2 has better flowing and pulling effects on the nylon mesh filter cloth, and the viscosity of the mud is ensured. The mud is attached to the nylon mesh filter cloth. Compared with other support medium materials such as paper, gypsum and wood board, the voids in the nylon mesh filter cloth can ensure the sufficient adsorption and adhesion of the mud, and the melting point of the nylon material is low, so that the nylon mesh filter cloth will not cause additional damage to the thin mud during the melting process at high temperature. When the filter cloth assembly is fired, the nylon mesh filter cloth is turned into ash, and the ceramic piece manufactured from the mud has a small thickness. The nylon mesh filter cloth provides a support medium for the mud for manufacturing the thin ceramic piece, and does not cause additional damage to the ceramic piece during the firing.

[0085] According to the method for manufacturing the ceramic piece, the paper pulp accounts for 0.2% of the total mass of the raw materials. In the related art, when the paper pulp is not included in the slurry for manufacturing the ceramic piece, the ceramic piece is prone to cracking due to the thin thickness and large area of the ceramic piece and the poor strength of the ceramic piece due to the thin thickness. In the embodiment of the present application, when the paper pulp accounts for 0.2% of the total mass of the raw materials, the pulling degree between the particles in the slurry can be increased, the strength of the ceramic piece can be increased, and the problem that the ceramic piece is prone to cracking when the ceramic piece is thin can be solved.

[0086] According to the method for manufacturing the ceramic piece, the nylon mesh filter cloth is a 120-mesh nylon mesh filter cloth, which can better ensure that the slurry is fully adsorbed and adhered in the gaps of the nylon mesh filter cloth, and further ensure that the slurry is not easy to be demolded before firing. In addition, during the drying process of the slurry, the surface on which the nylon mesh filter cloth is arranged is kept in a longitudinal arrangement state, the slurry can fully flow, and the thickness of the slurry is further reduced in the flowing and pulling, so that the thickness of the obtained ceramic piece is further reduced.

[0087] In some embodiments, the slurry for manufacturing the ceramic piece further includes 10% of the mass of the kaolin of the medium-temperature transparent glaze powder, and the proportion of the medium-temperature transparent glaze powder can protect the ceramic surface when the slurry forms the ceramic piece and enhance the durability of the ceramic piece.

However, the present application is not limited to the order of the above steps, that is, the steps can be performed in the order mentioned in the embodiments, or different from the order in the embodiments, or several steps are performed simultaneously.

[0089] The above merely illustrates the specific implementation of the present application, and those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the system, module and unit described above can refer to the corresponding process in the foregoing method embodiments, which will not be described herein.
