Description

Technical Field

[0001] The invention belongs to the technical field of handicraft preparation, and specifically relates to a ceramic powder sintering process method. Background Art

[0002] One of the main processes in producing ceramic products is to heat the ceramic body according to a certain thermal system, so that the body undergoes physical and chemical reactions under specific conditions of high temperature, and finally becomes a ceramic product with a fixed volume and a specific shape or performance. This production process is called ceramic firing. Common firing methods include primary firing and secondary firing, but the common firing method is to first make the ceramic into a shaped clay body and then fire the clay body at high temperature. Due to the high temperature of the firing process, the quality requirements for the clay body will also be high, otherwise the clay body will crack during the firing process, resulting in unqualified quality of the ceramic finished product. At present, most of the ceramic products on the market are hollow products, because the solid clay body is very easy to crack or even explode during the firing process. In addition, due to the limitation of the technological level, it is difficult to see thin and flexible ceramic products on the market, and even if there are, they are often expensive.

[0003] In summary, it is necessary to propose a new process that is different from the traditional ceramic firing method. Summary of the invention

[0004] The purpose of the present invention is to provide a ceramic powder sintering process method and a ceramic product prepared by the method, which partially solves or alleviates the above-mentioned deficiencies in the prior art. The present invention specifically adopts the following technical solutions.

[0005] In one aspect, the present invention provides a method for preparing a solid ceramic product.

[0006] A method for preparing a solid ceramic product based on sintering ceramic powder comprises the following steps: S01: Take the raw ceramic material, burn it in the range of 600-800℃ to obtain clinker, and further grind it into powder to obtain ceramic clinker particles with a particle size of less than or equal to 60 mesh; S02: Take a raw ceramic material, add water to prepare a clay body, and make a mold as needed, wherein the mold includes a hollow mold capable of loading the clinker particles or a solid mold capable of loading the clinker particles; for example, a hollow mold can be prepared by a wheel throwing process; or a solid base mold can be prepared by a slip casting process; and a release agent is coated on the mold; S03: filling the harvested ceramic clinker particles into the hollow mold to form a semi-finished product; or piling the harvested ceramic clinker particles onto the solid mold to form a semi-finished product; S04: placing the semi-finished product into a kiln for firing, the firing temperature range is 1200-1300°C (depending on the porcelain-forming temperature of the porcelain clay or pottery clay used), keeping the temperature for 10-30 minutes, and the entire firing time is 8-10 hours; S05: After firing is completed, the mold is removed to obtain the solid ceramic product.

[0007] Furthermore, the ceramic raw material includes porcelain clay, jade clay or pottery clay.

[0008] Furthermore, the isolation agent is aluminum oxide; and aluminum oxide is coated on the inner surface of the hollow mold or the outer surface of the solid mold.

[0009] Furthermore, the ceramic clinker particles are compacted when they are filled into the hollow mold. Optionally, the ceramic clinker particles are surface modified.

[0010] Furthermore, when the ceramic clinker particles are piled onto the solid mold, the ceramic clinker is compacted and the outer surface is trimmed (to make it as smooth and flat as possible).

[0011] When the ceramic clinker particles are piled on the solid mold, they have a certain height, for example, the pile height is above 0.5 cm.

[0012] Another aspect of the present invention provides a method for preparing a thin and light ceramic product.

[0013] A method for preparing a thin and light ceramic product based on sintering ceramic powder comprises the following steps: S01: Take the raw ceramic material, burn it in the range of 600-800℃ to obtain clinker, and further grind it into powder to obtain ceramic clinker particles with a particle size of less than or equal to 60 mesh; S02: fully and uniformly mixing the water-soluble sticky powder with water to obtain a sticky auxiliary material; S03: uniformly mixing the viscous auxiliary material and the ceramic clinker particles at a mass ratio of 2:1-2:1.5 to obtain a viscous ceramic raw material; S04: Take an elastic sheet carrier, and apply the sticky ceramic raw material to one side surface of the sheet carrier, wherein the applied sticky ceramic raw material needs to completely cover the sheet carrier and the applied weight does not exceed 5 times the weight of the sheet carrier; S05: Drying the sheet-shaped carrier coated with the sticky ceramic raw material so that the surface thereof is non-sticky and has a foldable hardness; S06: Put the dried sheet carrier into a kiln for firing, the firing temperature range is 1200-1300°C (depending on the porcelain temperature of the porcelain clay or pottery clay used), keep warm for 10-30 minutes, and the whole firing time is 8-10 hours; after the firing is completed, the thin ceramic product is obtained.

[0014] The invention provides a new material, namely a mixture of ceramic clinker and viscous auxiliary material. After the ceramic clinker and the viscous auxiliary material are mixed in a specific ratio, a light, thin and flexible ceramic product can be prepared.

[0015] It is understandable that the elastic sheet carrier will be burned during the firing process. The raw material is coated on the elastic carrier, and shrinkage and deformation will occur after firing. The present invention finds that using clinker can solve this problem well.

[0016] Furthermore, the ceramic raw material includes porcelain clay, jade clay or pottery clay.

[0017] Furthermore, the elastic sheet-like carrier is a fiber cloth, including polyurethane fiber, polyether ester elastic fiber, nylon or Lycra.

[0018] Furthermore, the water-soluble sticky powder includes polyvinyl alcohol powder, carboxymethyl cellulose powder or glutinous rice flour.

[0019] Furthermore, the sheet-like carrier coated with the sticky ceramic raw material is shaped as needed before firing; including spreading it on a predetermined mold before drying, or folding it into a predetermined shape after drying.

[0020] Beneficial technical effects: The present invention proposes a method for preparing solid ceramics and thin ceramics based on a ceramic powder sintering process. The present invention aims to explore the possibility of preparing the thickest ceramic process and the thinnest ceramic process (extreme to extreme) based on the same core process. Specifically, the process method of the present invention has the following advantages: (1) The drying process of traditional ceramic blank making is reduced, which alleviates the problems of blank cracking and simplifies the entire production process.

[0021] (2) After firing, the ceramic surface will have a special texture due to the shrinkage of the clay powder, which will have richer visual effects and high artistic value.

[0022] (3) By using simple methods and convenient materials, it is possible to prepare expensive and thin ceramic products. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The sheet-like carrier coated with the sticky ceramic raw material is shaped as required before firing, including laying it on a predetermined mold before drying, or folding it into a predetermined shape after drying.

[0040] See the process flow chart Figure 2 .

[0041] Example 2 This embodiment provides a specific example of a ceramic powder sintering process method.

[0042] S01: Prepare clinker: Jade clay (e.g. jade clay from Jingdezhen), burn the jade clay at 800℃ for 4-8h, and after it is burned into clinker, grind it into powder using a ball mill or a manual grinding mortar, and pass it through a 60-mesh sieve to harvest jade clay clinker particles with a particle size less than or equal to 60 mesh.

[0043] S02: Use refractory gypsum or ordinary pottery clay or porcelain clay to make a clay body, and then make a mold by throwing. The mold is a hollow mold, and then alumina is applied to the inner surface of the mold.

[0044] S03: Fill the clinker particles prepared in S01 into the hollow mold, compact them to form a green body, and then put the green body into a kiln for firing. The firing temperature range is 1240°C, the heat preservation time is 20 minutes, and the entire firing time is 8 hours.

[0045] S04: removing the outer mold of the ceramic product obtained after firing, and obtaining a columnar solid ceramic product. Figure 3 .

[0046] As a comparison, this embodiment also provides a ceramic finished product preparation in which alumina is not applied to the inner surface of the mold in S02, see Figure 4 As can be seen in the figure, the inner surface of the mold is not coated with alumina, and the clinker powder adheres to the mold.

[0047] As a comparison, this embodiment also provides an example of directly preparing solid ceramics with raw materials in S01, see Figure 5 The specific process is as follows.

[0048] S01: Prepare filling raw materials: jade soil (such as jade soil produced in Jingdezhen), grind it into powder using a ball mill or a manual grinding mortar, pass it through a 60-mesh sieve, and harvest jade soil clinker particles with a particle size less than or equal to 60 mesh.

[0049] S02: Use common pottery clay or porcelain clay to make a clay body, and then throw the clay body to form a mold, wherein the mold is a hollow mold.

[0050] S03: Fill the raw material particles prepared in S01 into the hollow mold, compact them to form a green body, and then put the green body into a kiln for firing. The firing temperature range is 1200°C-1250°C, the heat preservation time is 20 minutes, and the entire firing time is 8 hours.

[0051] S04: removing the outer mold of the ceramic product obtained after firing to obtain a solid ceramic product.

[0052] The results of this embodiment show that when raw materials are used to prepare solid ceramics, the ceramics will crack significantly after firing.

[0053] Example 3 This embodiment provides another specific example of a ceramic powder sintering process method.

[0054] S01: Prepare clinker: sinter the ceramic raw materials at 800℃ for 4-12h. After ensuring that the raw materials are sintered into clinker, grind them into powder using a ball mill or a manual grinding mortar, pass through a 60-mesh sieve, and harvest jade clinker particles with a particle size of less than or equal to 60 mesh. Ceramic raw materials include porcelain clay, clay, jade clay, etc.

[0055] S02: Prepare auxiliary materials: Heat and mix glutinous rice powder and water in a mass ratio of 1:1 to prepare a viscous auxiliary material (paste). Pour the paste on a glass plate and use a scraper to squeeze vigorously to ensure that the large particle powder and water are fully mixed.

[0056] S03: Evenly mix the prepared viscous auxiliary material and the clinker in a mass ratio of 2:1-2:1.5 (using a stirring tool to stir) to obtain a viscous ceramic raw material.

[0057] S04: Use ordinary pottery clay or porcelain clay to make a mold. The mold prepared in this embodiment is hemispherical. Spread the fiber cloth evenly on the mold. Use a scraper to scrape the sticky ceramic raw material on the fiber cloth. During the scraping process, ensure that the ceramic raw material is evenly coated and the coating should be as thin as possible. For example, the coated sticky ceramic raw material needs to completely cover the fiber cloth and the coating weight should not exceed 5 times the weight of the fiber cloth to ensure lightness; small amounts and multiple coatings can be used. After the sticky ceramic raw material is coated, place it in a ventilated place to dry or dry it in the sun, and the sticky ceramic raw material on the surface is not sticky, so as to obtain a fiber cloth coated with sticky ceramic raw material.

[0058] S05: The fiber cloth coated with the sticky ceramic raw material is removed from the hemispherical mold and placed in a kiln for firing. The firing temperature range is 1240°C, the heat preservation time is 20 minutes, and the entire firing time is 8 hours.

[0059] The process diagram of preparing the ceramic product in this embodiment and several other ceramic products prepared by the same method are shown in Figure 6 and Figure 7 , and obtain ceramic products similar to paper shape.

[0063] S03: Evenly mix the prepared viscous auxiliary material and the clinker in a mass ratio of 2:1-2:1.5 (using a stirring tool to stir) to obtain a viscous ceramic raw material.

[0064] S04: Take the fiber cloth, and use a scraper to scrape the sticky ceramic raw material onto the fiber cloth. During the scraping process, ensure that the sticky ceramic raw material is evenly coated, and the coating should be as thin as possible. The coated sticky ceramic raw material needs to completely cover the fiber cloth and the coating weight should not exceed 5 times the weight of the fiber cloth to ensure lightness; small amounts and multiple coatings can be used. After the sticky ceramic raw material is coated, place it in a ventilated place to dry or dry it in the sun, and the sticky ceramic raw material on the surface is not sticky, so as to obtain a fiber cloth coated with the sticky ceramic raw material.

[0065] S05: According to design requirements, the fiber cloth coated with the sticky ceramic raw material is folded into a predetermined shape.

[0066] S06: Put the fiber cloth folded into a predetermined shape into a kiln for firing. The firing temperature range is 1200℃-1300℃, the heat preservation time is 20 minutes, and the entire firing time is 8 hours.

[0070] S02: A green body formed by gypsum grouting is made using jade clay (e.g. jade clay produced in Jingdezhen) as a base.

[0071] S03: Place the clinker particles prepared in S01 on the sieve and shake them to make them evenly fall on the surface of the green body.
