Description
Technical field
The invention belongs to the ceramic making technical field, be specifically related to a kind of high technology ceramics with jade quality and preparation method thereof.
Background technology
Pottery is the general name of pottery and porcelain.Chinese have just invented pottery as far back as B.C. approximately 8000-2000 (Neolithic Age).Stupalith is oxide compound, nitride, boride and carbide etc. mostly.Common stupalith has clay, aluminum oxide, kaolin etc.Along with the progress of science and people's growth in the living standard, pottery is the requisite of people's daily life, again the artistic craft product, to be the working people gather materials on the spot and make product take manual production as main a kind of technique for adapting to living needs and esthetic requirement for it, nowadays is more and more to be paid attention to by common people and like.Its uniqueness is that it is science and technology and plastic arts, decorative art three's unification, and any ceramic process works all are to be combined by the quality of stupalith, moulding, decoration three parts.
Modern Ceramics gets involved in people's life by variety of way from multi-angle, comprises home room and carry-on ornaments.In recent years, along with improving constantly of people's aesthetic conceptions, people require also more and more higher for pottery quality, moulding, decoration, the pottery that traditional technology is made has high reserve value, but in the demand that gradually can not satisfy Modern Decorative aspect quality, moulding and the decoration.
In addition, existing ceramic process is for the performance of the quality, moulding and the decoration aspect that improve product, often must add organic shaping additive on the composition, and these organic shaping additives still will remove before pottery burns till, produce easily dusty gas when removing, to environment, be not inconsistent the requirement of environmental protection.
Summary of the invention
For overcoming the defective of prior art, the object of the present invention is to provide a kind of making method with high technology ceramics of jade quality, do not contain dusty gas, environmental protection in the whole technological process expellant gas; And the surperficial texture and the exquisite degree that have jade by the pottery that the method obtains.
Another object of the present invention is to provide a kind of high technology ceramics with jade quality, be made by making method of the present invention, make its outward appearance with jade and performance.
Another purpose of the present invention is to provide a kind of ceramic degreasing biscuiting equipment, solves the exhaust gas emission problem in the manufacturing method of ceramic.
The technical solution adopted in the present invention is as follows for achieving the above object:
A kind of making method with high technology ceramics of jade quality may further comprise the steps:
1) mixing granulator: main raw material and auxiliary material are added hot milling in mixing roll, granulation after the cooling obtains feed particles;
2) ejection formation: be injected in the metal die after with the feed particles melting with Jet forming machine, cooling obtains green compact;
3) degreasing biscuiting: green compact are put in the debinding furnace, debinding furnace is provided with second heating apparatus, between second heating apparatus and the debinding furnace vacuum fan is housed, vacuum fan also is equipped with at the top of debinding furnace, green compact are degreasing in debinding furnace, the waste gas that skimming processes produces is pumped in the second heating apparatus by the vacuum fan between second heating apparatus and the debinding furnace, changes into carbonic acid gas and water, and discharges by the top blower fan of debinding furnace;
4) high temperature sintering: when treating that debinding furnace is cooled to 50-60 ℃, the green compact after the degreasing are transferred to carry out high temperature sintering in the high temperature sintering furnace.
In order to make the pottery that obtains not only have the outward appearance of jade, and can improve hardness and the toughness of pottery; Preferably, main raw material described in the above-mentioned technique is a kind of in the mixed powder of alumina powder, Zirconium oxide powder, aluminum oxide and zirconic mixed powder, silicon oxide and aluminum oxide; Described auxiliary material is one or more mixing in binding agent, lubricant or the plasticizer; Wherein the fineness of main raw material is 0.3-1 μ m, and binding agent is the plastic grain of diameter 3-7mm, and lubricant is that fineness is the 0.1-1mm fine particle, and plasticizer is liquid or cured shape or grease-like, and main raw material and auxiliary material volume fraction are:
Main raw material 50%-60%
Binding agent 30%-50%
Lubricant 0%-5%
Plasticizer 0%-10%
More than the volume summation of each component be 100%.If the ceramic raw material powder too slightly can cause product to be difficult to moulding in the above-mentioned technique, and the product surface texture behind the sintering does not reach requirement, and material too carefully can cause difficult forming, and the fineness that therefore is chosen in raw material can have the advantage of easy-formation and easy-sintering simultaneously concurrently at the 0.3-1 micron.
Described binding agent is one or more mixing among PS, PE, PP, PEO, PEG, EVA, PVB, the PMMA; Described lubricant is stearic acid or calcium stearate; Described plasticizer is a kind of among paraffin, DOP, the DBP.
In the above-mentioned technique, can to mix in order making between main raw material and the auxiliary material, further to improve surperficial texture and the fineness of product, preferably, add hot milling in the step 1) more than twice, the temperature of mixing roll is 100-200 ℃, and each mixing time is 4-6 hour.
In the above-mentioned technique, the temperature of degreasing biscuiting is 200-400 ℃ in the step 3), and the temperature in the second heating apparatus is 600-1200 ℃; The time of degreasing biscuiting is controlled at 12-48 hour.In the temperature-rise period of debinding furnace, when temperature reaches 200 ℃, green compact begin obvious degreasing, go out the part organic gas, these organic gass are pumped into to pass through in the second heating apparatus by rear vacuum fan and discharge after second-heating resolves into carbonic acid gas and water again, prevent that effectively obnoxious flavour is discharged in the air.
The temperature of high temperature sintering is 1250-1700 ℃ in the step 4), and the time is 10-24 hour.
In order to remove as much as possible having and auxiliary material in the product, improve the hardness of product, manufacturing method of ceramic with jade quality of the present invention also is included in step 2) and step 3) between the step of chemical degreasing: when ejection formation is cooled to 50-65 ℃, soaks with organic solvent and to slough the part tackiness agent in 1-15 hour.The solvent that adopts is this area solvent commonly used, such as normal hexane, dimethylbenzene etc.
In order to obtain the ceramic product of different pattern, satisfy different needs, manufacturing method of ceramic with jade quality of the present invention also is included in the glazing step between step 3) and the step 4): or/and glaze, the green compact after the glazing carry out high temperature sintering again to colorant on the green compact that cool off after the degreasing biscuiting.
A kind of high technology ceramics with jade quality, it is to be made by the above-mentioned making method of the present invention.
A kind of ceramic degreasing biscuiting equipment, it comprises debinding furnace, and debinding furnace is provided with second heating apparatus, between second heating apparatus and the debinding furnace vacuum fan is housed, vacuum fan also is equipped with at the top of second heating apparatus, and it also comprises the temperature control unit that is connected with second heating apparatus respectively at debinding furnace.
Compared to existing technology, beneficial effect of the present invention is: the making method environmental protection with high technology ceramics of jade quality of the present invention, pollution-free, and the surperficial texture and the exquisite degree that not only have jade by the pottery that the method obtains, and can also improve hardness and the toughness of ceramic product, the hardness of the ceramic product that obtains can reach Mohs 8-9 degree, and toughness can reach the toughness scope of jadeite.Pottery with jade quality of the present invention has outward appearance and the performance of jade.
