Editor's note: Pressure-sealing sealing medium--leaf stone is an important material for synthesizing diamond by static pressure method. After more than 40 years of mining application, the resources of pyrophyllite suitable for static pressure synthesis in China have been surpassed. Less, it has attracted the attention of entrepreneurs and scientific and technological workers engaged in the research and development and production of synthetic diamonds in China. They have prepared for the research and development of pyrophyllite substitutes. Shaoguan Saipu Superhard Material Technology Co., Ltd., under the leadership of General Manager Zhang Zhan, conducted a systematic study on the substitutes of pyrophyllite and made significant progress. Now they have produced the pressure-transfer medium standard powder and Beijing. The performance of Mentougou pyrophyllite is as follows for reference. Comparison of the performance of pressure-transfer medium standard powder and Beijing Mentougou pyrophyllite 1. Stability: The pressure-transfer medium standard powder is blended with relatively pure single-component materials, and there is no significant difference in performance between batches; Beijing Mentougou pyrophyllite The stability of the direct use after crushing and grading is subject to the distribution of each component in the original ore; the stability of the standard powder of the pressure transmitting medium is better than that of the Beijing Mentougou pyrophyllite. Second, pressure transfer: the same size, the same cavity, the pressure medium of the standard powder made of synthetic blocks than the Beijing Mentougou pyrophyllite after the crushing and classification of the synthetic block used on the same press using a low pressure of 2.5%, pressure transmission The pressure transfer property of the medium standard powder is better than that of the Beijing Mentougou pyrophyllite. Third, the sealing property: a single component material with a very high rebound coefficient is added to the standard powder of the pressure transmitting medium, and the component plays a decisive role in the sealing property of the pressure transmitting medium, and the adjusted standard powder is interrupted in the initial stage of the synthesis. The rear section has a good seal. 4. Insulation: A large number of insulator materials are intentionally added to the standard powder of pressure-transfer medium. The insulator components are evenly distributed in the standard powder of pressure-transfer medium. The insulation coefficient of the composite block made of standard powder is larger than that of the single-leaf stone. . V. Insulation: The thermal insulation of the standard pressure-transfer medium is better than that of the Beijing Mentougou pyrophyllite. When the high-pressure synthesis is performed on the same press in the same cavity, the heating power used by the former is about 3% lower than the latter. The pressure-transmitting medium standard powder has good heat insulation. 6. Operationality: The standard process of pressure-transfer medium is the same as that of Beijing Mentougou pyrophyllite when making the synthesis fast, but the prepared synthesis is not heated to 120-140 °C before loading into the press. The former oven temperature can be controlled at 60-70 ° C, and the standard powder has good operability. 7. Cost-effectiveness: When the synthetic quick size is the same, the standard powder dosage is less than 5% of the Beijing Mentougou pyrophyllite. When the two prices are the same, the pressure-transmitting medium standard powder is cost-effective.
