Description of the invention: [Technical field to which the invention pertains] The present invention relates to a ceramic luxury body and a glue which are respectively mixed with water and heated, and in particular, a method for solidifying a ceramic powder into a ceramic body; ”:::The precision of the internal density of the mold with capillary pores 复杂 Complex, surface smoothing and [prior art] φ Multi- and high-mold forming method has been used to form the pottery _===== The tiny capillary of the holed mold will use the mud's moisture: 5 疋 疋 疋 模具 而 而 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 The high pressure is used to press the water of the slurry into the open pores in the resin mold to solidify the slurry. The above two components are removed by the open pores, so that the crucible is formed quickly and the slurry is solidified. The advantages of the house. But there are still many defects that need to be changed. The injection molding method is the moisture adsorption of the hair of the Xiang model body and thus achieves the effect of curing the body. Therefore, the number of capillaries of the gypsum body will be Capillary, the capillary of the body Good or bad, the number of big 1 and the number of knives 1 is determined by the mixing of water and gypsum. The ratio of water to gypsum is artificially modulated. In practice, the ratio of paste to water is easy to produce errors, resulting in differences in the pottery produced. In addition, in order to reduce the drying shrinkage rate of the body, the deformation rate 'must add an additive, but the external additive of the carcass and the polymer 5 200936530 = 3 can not be too fine, because the particles are too thin to block the second Capillary pores not only make the molding time of the pottery and scorpion body "the number of times of use and the problem of difficulty in demoulding, but if the pottery: = is thin enough", it is impossible to make a ceramic-changing object with high dimensional precision. Furthermore, the current casting of gypsum molds = thinner and smallerer Taur, for complex shaped two = ❹ ceramic objects, m贱 or thicker is the substrate 'has difficult to form. The reason for this is that a mold having a complicated shape is produced, and the capillary of the plaster mold body is difficult to mold in the case of a ceramic change (four) which requires a large amount of moisture absorption. Generally, the thicker part (4) requires a large amount of water to absorb the body's moisture, but the plaster mold can only absorb the moisture of the slurry part. This phenomenon will lead to the arrangement of the later stage of the pottery grain during the process of perfusion molding. (4) The arrangement of the four bodies is different, resulting in the stratification of the four bodies. When sintering, it is easy to cause the body to crack. The high-pressure injection molding method and the gypsum injection molding have similar molding methods and restrictions, so the problem caused by the plaster casting molding may also occur in high-pressure injection molding. In view of this, in order to improve the above-mentioned shortcomings, the ceramic molding method can not only manufacture precision ceramics, but also effectively improve the yield of the ceramic products, and the inventors have accumulated many years of experience and continuous research and development improvements, and have the production of the present invention. ^. SUMMARY OF THE INVENTION The main object of the present invention is to provide a ceramic powder and a glue separately mixed with water, and after heating to form a jelly-like body, to coagulate fine ceramics 6 200936530 particles, and can be sintered into a precision pottery Research on the formation method.舆水=: powder, _ separate chain material molding = surface smoothing and uniform internal density of the ceramics Another object of the present invention / 4 + ^ luxury billet can be solidified molding of bad ceramics (four) recycling Use to save the natural resources of the ceramics forming method. 2 For the purpose of the above invention, the pottery forming method of the present invention mainly comprises the following steps: a. providing a mixture of ceramics and water - a mixture of diterpenes; b. providing a mixture of knee and water Forming a second mixture and preheating; C. mixing the first mixture with the second mixture into a third present compound for injection into a mold having no capillary pores; and d.
