Description
Technical field
The present invention relates to a kind of process that can improve resin-diamond monolithic production capacity, belong to superhard material synthetic technology
Field.
Background technology
In artificial diamond's Stone technique, the most ripe and obtain wide application is static pressure method (high temperature and high pressure method), it is main
It is that the high temperature that the Static pressure utilizing hydraulic pressure cubic hinge press to produce and electric current produce makes graphite undergo phase transition under the effect of catalyst
Being converted into polycrystalline diamond, polycrystalline diamond is compared with single-crystal diamond, and granule is irregular, is better than it on refining applications
Its superhard material product, is used for the products such as resin bond wheel, so this polycrystalline diamond is also referred to as resin-diamond.
Resin-diamond is affected by synthesis technique at present, and synthetic cavity is Φ 30-Φ 35mm, and monolithic yields poorly, and additionally closes
Becoming overlong time, temperature, pressure requires height, causes large-scale production relatively costly, and production efficiency is low.
Summary of the invention
In order to overcome drawbacks described above, the present invention provides a kind of process that can improve resin-diamond monolithic production capacity.
To achieve these goals, the technical scheme is that a kind of work that can improve resin-diamond monolithic production capacity
Process, described process is: the Synthetic block that will be equipped with catalyst and raw material is inserted in press, through High Temperature High Pressure synthetic resin gold
Hard rock, pressure curve is as follows: boost to 42-45MPa within the 58-65 second, afterwards the pressurize 58-62 second, then boosts in the 10-20 second
To 46-48MPa, pressurize 215 seconds-230 seconds, finally within the 30-45 second, blood pressure lowering is 0；
Heating power curve is: began to warm up when 45 seconds-55 seconds, and heating power is 4.8-5.2Kw, is incubated 58-62 second processus aboralis
Reducing to 4.1-4.3Kw, insulation 115-125 second processus aboralis reduces to 0 afterwards.
Preferred as one, above-mentioned heating power curve is: began to warm up when 50 seconds, and heating power is 5Kw, is incubated 60
Second processus aboralis reduces to 4.1Kw, and 120 seconds processus aboralis of insulation reduce to 0 afterwards.
In order to be able to obtain the highest quality product, the catalyst employed in the present invention includes boron-containing compound；
In order to adapt to and stablize the process of the present invention, the pyrophillite in Synthetic block of the present invention by the following method and
Raw material is made: Absoulute Black pyrophillite carries out batch mixing by large, medium and small granularity 5:4:1, large, medium and small grain graininess be respectively 2mm,
1mm, 0.3mm, it is molded that the water glass adhesive additive of interpolation 10% carries out powder, it is ensured that pressure transmission, heat-insulating property meet technique needs,
And effectively solve large cavity resin-diamond High Temperature High Pressure building-up process occurs split hammer consumption problem.
The invention has the beneficial effects as follows: the process of the present invention can be widely used in the production of large cavity monolithic, improves
The yield of monolithic and the production capacity of equipment, the polycrystalline diamond utilizing this technique to produce is inserted or Ma Saike shape, has relatively
High heat stability and high grinding efficiency, fabulous self-sharpening energy.Additionally, power bust after heating 60 seconds, effectively improve
The self-sharpening of resin-diamond.
