Abstract
The utility model relates to a composite pyrophyllite powder pressing block, which comprises a main body (1), mould cavity holes (4) arranged on the main body, and dolomite linings (5) arranged in the mould cavity holes. The utility model is characterized in that lining rings (7) are arranged in the mould cavity holes arranged on the upper part of the linings (5); inner rings (8) are arranged in the lining rings (7); the center of the inner rings (8) is provided with through holes (9) which is provided with electric conduction poles. Because the utility model is provided with lining rings (7), carbon sheets and catalyst sheets arranged in the utility model can not deviate from the center of mould cavities.
Description
The utility model relates to chemistry or physical method, for example: katalysis, colloid chemistry; Its relevant devices.Be particularly related to and utilize the method that barometric point makes material generation chemistry or physical change that is below or above, and relevant devices.
The fissile-wax stone briquetting be static must use when producing man-made diamond with the overflow mould of fissile-wax stone as transmission medium, briquetting has a die cavity, the die cavity two ends are porose, the built-in conducting electrode in hole, built-in (graphite) sheet of die cavity and catalyst during work make in the die cavity by electrode pair die cavity energising and to heat, to six pressurizations of briquetting, pressure can reach in the die cavity, and under the High Temperature High Pressure effect, carbon plate can change into diamond.
Though fissile-wax stone is more satisfactory as transmission medium, when High Temperature High Pressure, still have some character not meet the demands, for example:
Fissile-wax stone can produce phase transformation and mineral density is increased under the high temperature of diamond synthesis, volumetric shrinkage, thereby cause die cavity to increase, internal pressure descends.Simultaneously, after the phase transformation, frictional coefficient and intensity all increase and are rigidity, influence the pressure transmission effect under the High Temperature High Pressure.
And for example, at high temperature, the crystal water of fissile-wax stone can be separated, and may resolve into hydrogen and oxygen or hydroxide radical, and these resolvents transform very harmful to graphite to diamond.
Now invented another kind of transmission medium, be rhombspar, it does not at high temperature have the reversible phase transformation, and its coefficient of expansion big than fissile-wax stone, be three times of fissile-wax stone, at high temperature, fissile-wax stone produces phase transformation and volumetric shrinkage, and the coefficient of expansion descends, and the rhombspar coefficient of expansion is constant, then the difference of both coefficients of expansion at high temperature is just very big, and the heat-conduction coefficient of rhombspar also is lower than fissile-wax stone, therefore helps the raising of temperature in the die cavity.
But rhombspar can scatter under High Temperature High Pressure when being used for diamond synthesizing process, can not finish the pressure transmission task, so can not make overflow mould separately.
For addressing the above problem, the applicant has applied for a kind of compound fissile-wax stone briquetting, body with fissile-wax stone, in die cavity is arranged, there is the through hole that cooperates with conducting electrode the die cavity lower end, there is the fissile-wax stone ring of the conducting electrode of putting the upper end, mould intracavity wall has the lining of dolomite made, liner sleeve length is less than the length in the hole on the body, therefore put the fissile-wax stone ring on the lining, in the hole of the body of lining upper end, have one section not have lining, when being higher than lining as the carbon plate that loaded or catalyst sheet, carbon plate that exceeds or catalyst sheet can depart from the center of die cavity, when putting into the fissile-wax stone ring of conducting electrode again, be empty while the fissile-wax stone ring can be pressed in above the carbon plate, cause electrode and carbon plate and catalyst sheet loose contact, temperature is not enough, and a hammer pressure can not well reach carbon plate.
The purpose of this utility model provides a kind of composite fissile-wax stone flour briquetting that can make carbon plate and catalyst sheet can not depart from the die cavity center.
The purpose of this utility model realizes by following technical scheme, the body that composite fissile-wax stone flour briquetting has fissile-wax stone system, intrinsic cavity hole, the through hole that matches with conducting electrode of one end of cavity hole, the lining of the dolomite made in the cavity hole, it is characterized in that in the cavity hole above said lining grommet being arranged, have interior ring in the grommet, there is the through hole that matches with conducting electrode at interior ring center.
This composite fissile-wax stone flour briquetting when filling carbon plate and catalyst sheet, installs lining and grommet earlier in cavity hole, charging then, because grommet is arranged, so carbon plate and catalyst sheet can not depart from the die cavity center, put into ring and conducting electrode again, conducting electrode can be pressed on the carbon plate fully.
Below in conjunction with drawings and Examples composite fissile-wax stone flour briquetting of the present utility model is explained in detail.
Fig. 1 is the sectional view of the utility model composite fissile-wax stone flour briquetting;
Fig. 2 is the sectional view of the utility model composite fissile-wax stone flour briquetting along A-A face among Fig. 1.
As Fig. 1, Fig. 2, composite fissile-wax stone flour briquetting has the body 1 of fissile-wax stone system, this body profile is square, four sides can be the planes, also can have the concave station 6 that matches with diamond press top tup portion, cavity hole 4 is arranged in the body, cavity hole 4 one ends have the through hole 3 of placing conducting electrode, the other end is a clear opening, the lining 5 that removable (as running fit) or fastening are equipped with dolomite made in the cavity hole 4, the endoporus of lining 5 is a die cavity, the length of lining 5 is less than the length of cavity hole 4, so that place the fissile-wax stone ring of dress conducting electrode at the through hole end of cavity hole 4, when the carbon plate of the die cavity of packing into and catalyst sheet are higher than lining 5, they will depart from the die cavity center and influence the correct installation of fissile-wax stone ring, for carbon plate that is higher than lining and the catalyst sheet that makes the die cavity of packing into can not depart from the center, the grommet 7 that above lining 5, has fissile-wax stone system, its external diameter is identical with lining 5 with internal diameter, one end and lining 5 join, the other end is top equal with body 1, ring 8 in also having in the grommet 7, the internal diameter running fit of its external diameter and grommet 7, there is the through hole 9 that matches with conducting electrode at the center, when dress carbon plate and catalyst sheet, lining and grommet are together put into the cavity hole of body, so carbon plate can not depart from the center.
When use has the conducting electrode of stretching out the ring limit, the concave station 2 that has the ring limit with this kind conducting electrode adapt in the outside of through hole 3, the concave station 10 that has the ring limit with this kind conducting electrode adapt in the outside of the through hole 9 of interior ring 8, four sides of body 1, can be the plane, also can have the concave station 6 that matches with the top tup portion of diamond press.
