Abstract
The present invention relates to a kind of synthesis high quality synthetic diamond platelet manufacturing methods of brilliant bed, it is by raw material being repeated the process of crushing and compacting, realize the screening to brilliant bed raw material, made brilliant bed is more suitable for high quality synthetic diamond platelet, and the synthesis of platelet is carried out using crystalline substance bed made from this method, it is ensured that the degree of purity of brilliant bed.Brilliant bed of the invention, to the repeatability of high grade platelet is synthesized preferably, the platelet synthesized is pale yellow without inclusion enclave color, and the transparency of platelet is good, and quality is good, it can be achieved that producing in batches and production cost is low.
Description
Technical field
The present invention relates to a kind of synthesis high quality synthetic diamond platelet manufacturing methods of brilliant bed.
Background technique
The manufacturing process of diamond platelet is to cause have inclusion enclave inside platelet due to brilliant bed, a synthesis
Crystal varies inconsistent phenomenon in block, and the platelet color synthesized is deeper, synthesis technology poor repeatability, and block rate of giving up is higher
The problem of.In order to synthesize high quality synthetic diamond platelet, useless block rate is reduced, improves the repeatability of synthesis technology, spy is to crystalline substance
Bed production method optimizes, and reduces production cost.
Summary of the invention
The present invention provides a kind of synthesis high quality synthetic diamond platelet manufacturing methods of brilliant bed, it passes through to raw material
The process of crushing and compacting is repeated, realizes the screening to brilliant bed raw material, it is artificial that made brilliant bed is more suitable for high grade
Diamond platelet, and using the synthesis of the progress platelet of crystalline substance bed made from this method, it is ensured that the degree of purity of brilliant bed.
The present invention realizes that above-mentioned purpose uses following technical scheme:
A kind of manufacturing method of the brilliant bed of synthesis high quality synthetic diamond platelet, it uses high-purity mangesium oxide magnesium powder for original
Distilled water is added wherein and is mixed, is then suppressed for material；It is crushed after the completion of compacting and is granulated and is sieved using sieve
Then choosing is suppressed screening object again；It is fired after screening and compacting repeatedly.
The purity of the high-purity mangesium oxide magnesium powder is 99.99%, and the mesh number of the magnesia powder as raw material is 300 mesh.
In the cyclic process suppressed and crushed, the pressure of pressing process successively reduces the magnesia powder.
A kind of manufacturing method of the brilliant bed of synthesis high quality synthetic diamond platelet, it the following steps are included:
(1) distilled water that its weight 2% is added in the magnesia powder (300 mesh) for being 99.99% by purity mixes；
(2) magnesia powder of mixing is pressed into four-column press with 15Mpa pressure to the cylindrical body of 3-4 millimeters thick；
(3) it will be pressed into after cylindrical body is crushed and be granulated into fine grained in mortar, and cross the sieve of 80 mesh；
(4) screenings is pressed into four-column press with the pressure of 10Mpa to the cylindrical body of 3-4 millimeters thick；
(5) then entering to dry case with 1400-1600 degree fire 4-8 hour as finished product.
The present invention has the advantages that by adopting the above technical scheme
By carrying out compacting and broken screening repeatedly to raw material, there is brilliant bed made by the raw material can in use
The useless block rate of the reduction of effect, guarantees the quality of obtained platelet；Also, this manufacturing method is applied to synthesize the high artificial gold of grade
Among the production of hard rock platelet, it can successfully synthesize the light yellow platelet of high cleanliness, and repeatability is preferably, production cost is low,
The market competitiveness of raising company.
Specific embodiment
A kind of manufacturing method of the brilliant bed of synthesis high quality synthetic diamond platelet, it uses high-purity mangesium oxide magnesium powder for original
Distilled water is added wherein and is mixed, is then suppressed for material；It is crushed after the completion of compacting and is granulated and is sieved using sieve
Then choosing is suppressed screening object again；It is fired after screening and compacting repeatedly.
The purity of the high-purity mangesium oxide magnesium powder is 99.99%, and the mesh number of the magnesia powder as raw material is 300 mesh.
In the cyclic process suppressed and crushed, the pressure of pressing process successively reduces the magnesia powder.
The present invention is further illustrated for set specific embodiment below.
The preparation of brilliant bed is carried out using the magnesia powder that purity is 99.99% as raw material, the mesh number of magnesia powder is 300
Mesh.
Specific preparation process is as follows:
(1) distilled water that its weight 2% is added in the magnesia powder (- 300 mesh) for being 99.99% by purity mixes；
(2) magnesia powder of mixing is pressed into four-column press with 15Mpa pressure to the cylindrical body of 3-4 millimeters thick；
(3) it will be pressed into after cylindrical body is crushed and be granulated into fine grained in mortar, and cross the sieve of 80 mesh；
(4) screenings is pressed into four-column press with the pressure of 10Mpa to the cylindrical body of 3-4 millimeters thick；
(5) then entering to dry case with 1400-1600 degree fire 4-8 hour as finished product.
Of light color, the pure interior that is manufactured that brilliant bed synthesizes diamond platelet under such condition, grade are high.
