The composite pyrophyllite powder briquette manufactured by the invention has good performances for sealing, pressure-transmitting, heat-preserving and insulating, provides a good environment for the nucleation growth of the superhard material, has stable flowing property and is easy for forming a sealing surface, thereby effectively reducing the phenomena of deflation and explosion during the superhard material synthesis, saving electrical energy due to the good heat preservation performance, improving the productivity due to the good pressure-transmitting performance and reducing the cost. Only South Africa owns the industrial pyrophyllite in the field of the superhard material in the world, and only Beijing Mentougou owns mineral resource in China which is insufficient. The composite pyrophyllite material is the substitute of the two and is better than the two.
Description
Technical field
The present invention relates to superhard material synthetic in employed hermetical and pressure madium material, particularly relate to a kind of composite pyrophyllite material.
Background technology
Agalmatolite is a kind of hydrous alumino silicates, acid volcano extrusive rock in being mainly, and molecular formula is AL
2[Si
4O
10] (OH)
2Agalmatolite have good seal performance, high pressure lower volume shrink little, thermal conductivity is low and mobile characteristics such as good, be superhard material man-made diamond, composite sheet or cubic boron nitride etc. synthetic in the general transmission medium (being commonly called as the pyrophyllite powder briquetting) of use of institute, in the superhard material height is pressed into, be used widely.
Yet facts have proved, in six-plane piercer synthesis of artificial superhard material production process, adopt single agalmatolite to exist tangible deficiency as transmission medium.Because contain planar water and crystal water in the agalmatolite, in the process of synthetic single crystal and composite sinter, the intravital temperature in chamber can reach 1200～1500 ' C, therefore in building-up process, agalmatolite can dewater, phase transformation, produce the thick shell of kyanite and coesite, thereby mineral proportion increases, volumetric shrinkage causes the decline of synthetic cavity internal pressure, produces pressure gradient, its heat-insulating property and pressure transmission performance be variation all, thereby the growing environment of superhard material in the synthetic chamber is changed, cause superhard material crystal mass instability, thereby had a strong impact on the generation of gem-quality crystal.
In addition, planar water in the agalmatolite and crystal water can decompose under high temperature, high pressure, separate out and resolve into hydrogen and oxygen or hydroxide radical, these hydrogen, oxygen impurities also might enter crystals or be present in the superhard material crystals with the oxide form of metal, influence giving birth to nuclear and growing up of superhard material, and then influenced the output and the quality of superhard material monocrystalline.Therefore, adopt single agalmatolite to make the pressure transmission thermal insulation medium and have many deficiencies.
The industrial compound seal transmission medium that generally adopts replaces single pyrophyllite material medium at present.The compound seal transmission medium generally is made up of agalmatolite and rhombspar, rhombspar is compared with agalmatolite, its inside does not contain crystal water, under High Temperature High Pressure, do not undergo phase transition, and its thermal expansivity is big, be 3 to 4 times of agalmatolite, heat-conduction coefficient is littler than agalmatolite, it is 73.6% of agalmatolite, therefore, the rhombspar of pressing close to carbon source and catalyst does not undergo phase transition under high temperature and high pressure, does not have volume change in the building-up process, avoid the pressure in the synthetic chamber to descend, can remedy the above-mentioned defective of agalmatolite with white clouds masonry transmission medium to a certain extent.But sealing, the heat retaining property of rhombspar are poor, so often the white clouds madreporic canal are embedded in the actual production and make a kind of composite powder briquetting in the agalmatolite.Pressure transmission, sealing, insulation, insulation are finished jointly by agalmatolite and rhombspar.So mutual collocation is maximized favourable factors and minimized unfavourable ones, and both are in conjunction with being easier to superhard material growth, and is all beneficial to the color of superhard material, grade etc.
In the composite powder briquetting, the main effect of agalmatolite is sealing, insulation.Present pyrophyllite powder briquetting is mainly by pyrophyllite deposit stone powder and tackiness agent compression molding, the quality instability, very easily blow out phenomenon in high temperature, high pressure building-up process, in case blow out, the building-up process of superhard material has not only terminated, and cause the top hammer of six-plane piercer all to scrap, once blow out and just will cause 3 to 40,000 yuan direct economic loss.The immediate cause that generation is blown out is exactly that composite pyrophyllite material in the composite pyrophyllite briquetting causes in that the High Temperature High Pressure current downflow is unstable.
Summary of the invention
Technical problem to be solved by this invention provides the composite pyrophyllite material in a kind of composite pyrophyllite briquetting, this material has sealing, characteristics that heat retaining property is high, and flowing property is stable, can form trim, for superhard material provides a good growing environment, and reduced the phenomenon of blowing out of superhard material building-up process effectively.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention provides a kind of composite pyrophyllite material, and it is made up of following raw materials by weight percent:
Agalmatolite 50%～60%;
Thin,tough silk cloud nurse stone 12%～20%;
Kaolinite 8%～15%;
Boehmite 5%～10%;
Tackiness agent 5%～10%.
Wherein agalmatolite, thin,tough silk cloud nurse stone, kaolinite and boehmite are respectively 40～100 purpose powder, and tackiness agent is a kind of in wood shavings alkali, 107 glue or the white glue with vinyl, generally adopts wood shavings alkali No. 51.
As mentioned above, a kind of prescription of the present invention is as follows: it is made up of following raw materials by weight percent:
Agalmatolite 58%;
Thin,tough silk cloud nurse stone 18%;
Kaolinite 9%;
Boehmite 8%;
Tackiness agent 7%.
Experiment showed, use that the present invention makes composite pyrophyllite briquetting advantage specific as follows:
The first, do not exit, do not blow out in synthesizing, stop the heating back with regard to fast pressure relief, improved production efficiency, the consumption of Wimet simultaneously also reduces significantly, can drop to the 0.5-1kg/ myriagram under the general situation and draw.The not bad top hammer of have even some months will make product cost descend greatly thus.
The second, process stabilizing, good reproducibility.
The 3rd, good heat insulating has reduced the thermograde of synthetic cavity, has built a superhard material nucleating growth environment preferably.
The 4th, the pressure transmission performance is good, reduces the 3-4 MPa than common agalmatolite under the equal conditions that the clavicorn degree is identical on the top, cavity is identical.Thereby can improve usage ratio of equipment.
Only with 59 millimeters of the cubes bottom surface length of sides, the composite powder briquetting that internal diameter is 39 millimeters is an example: use the coventional type agalmatolite to need the synthesis pressure of 100-105 MPa, the briquetting that adopts the present invention to make, under equal conditions pressure can reduce the 3-4 MPa, therefore can effectively prolong duration of service.In addition,, shortened the heat-up time when synthesizing because of good heat insulating, but saves energy 40%.
