Abstract
The utility model relates to an electroconductive thermal insulating pressure transferring sheet for the artificial diamond production. The utility model is composed of electroconductive parts and a thermal insulating pressure transferring block which is made from dolomite powder. Both the production capacity and the quality of the diamond crystal body produced by the utility model are obviously improved, and simultaneously, the environmental condition requirement of the artificial diamond production is reduced. The utility model can effectively save the energy and reduce the energy consumption.
Description
The utility model relates to used parts in the diamond crystal building-up process.
Be used for the synthetic equipment of diamond in the prior art belt type press and cubic hinge press are arranged, the conductive heat insulation pressure transmission sheet that places the reaction cavity of press is to be used for the synthetic critical component of diamond, and the quality of its performance and diamond crystal synthetic has confidential relation.In actual production, the conductive heat insulation pressure transmission sheet that people use adopts the pyrophyllite material molded through turning or powder more, again through heat treatment, operations such as pressing make, at super-pressure, under the superhigh temperature synthesis condition, because the pyrophyllite material easily undergoes phase transition, generate phase-change product, be accompanied by the generation volume contraction, cause the high pressure chest internal pressure of press reaction chamber to descend and thermal loss, thereby cause synthesis pressure, the loss of power, can cause the deterioration of diamond synthesis condition like this, be unfavorable for the growth of diamond crystal, reduced the service life of cylinder pressure and top hammer greatly.
The purpose of this utility model is to provide that a kind of manufacture craft is simple, stable performance, cost is lower, synthetic effect is good conductive heat insulation pressure transmission sheet.
The purpose of this utility model is achieved in that conductive heat insulation pressure transmission sheet contains conductive component and heat insulation pressure transmission piece, and heat insulation pressure transmission piece adopts dolomite dust to add an amount of binding agent and is uniformly mixed into thick embryo powder, and repressed moulding is made through Technology for Heating Processing again; Heat insulation pressure transmission piece is compressed into corresponding conductive component, make product conductive heat insulation pressure transmission sheet of the present utility model, conductive component is cylindrical conductive steel ring or cylindrical conductive steel lid.
The material that the utility model adopts is a dolomite dust, and it is low and do not have the characteristics of phase transformation substantially under synthesis condition that it has thermal conductivity, thereby overcome the existing above-mentioned defective of pyrophyllite.The Technology for Heating Processing of conductive heat insulation pressure transmission sheet preparation process is also simplified greatly; Sintering after the repressed moulding of employing dolomite powder need not in mill processing; The conductive heat insulation pressure transmission sheet that makes more reaches unanimity in the physical property of all directions.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the Front view 1-1 of embodiment 1 conductive heat insulation pressure transmission sheet of the present utility model and overlooks Fig. 1-2
Fig. 2 is Front view 2-1, vertical view 2-2 and the upward view 2-3 of embodiment 2 conductive heat insulation pressure transmission sheets of the present utility model
Among Fig. 1 embodiment 1 of the present utility model: the cylindrical heat insulation pressure transmission piece that 1--cylindrical conductive steel ring 2--dolomite dust and small amount of binder are made
Among Fig. 2 embodiment 2 of the present utility model: the cylindrical heat insulation pressure transmission piece that 3--cylindrical conductive steel lid 4--dolomite dust and small amount of binder are made
Embodiment 1
As shown in Figure 1, the conductive component that conductive heat insulation pressure transmission sheet contains is cylindrical conductive steel ring 1 and heat insulation pressure transmission piece 2, and heat insulation pressure transmission piece 2 adopts dolomite dust to add an amount of binding agent and is uniformly mixed into thick embryo powder, and repressed moulding is made through Technology for Heating Processing again; Heat insulation pressure transmission piece 2 is compressed into corresponding cylindrical conductive steel ring 1, make product conductive heat insulation pressure transmission sheet of the present utility model.
As shown in Figure 2, the conductive component that conductive heat insulation pressure transmission sheet contains is cylindrical conductive steel lid 3 and heat insulation pressure transmission piece 4, and heat insulation pressure transmission piece 4 adopts dolomite dust to add an amount of binding agent and is uniformly mixed into thick embryo powder, and repressed moulding is made through Technology for Heating Processing again; Heat insulation pressure transmission piece 4 is compressed into corresponding cylindrical conductive steel lid 3, make product conductive heat insulation pressure transmission sheet of the present utility model.
The utility model conductive heat insulation pressure transmission sheet can be widely used in synthesizing of diamond on two sides top and the cubic hinge press.
Show that through the experimentation checking product of the present utility model can replace the corresponding goods that adopt the pyrophyllite material to make fully.Compare with the conductive heat insulation sheet that former pyrophyllite material makes, the production building-up process that the conductive heat insulation pressure transmission sheet that uses the utility model to make is used for diamond can make the synthetic required pressure of diamond crystal reduce, required synthetic power also reduces, and the grade of the diamond that generates increases, productive rate improves, and technology is more stable; The reduction significantly of synthesis pressure and power in the service life that helps improving cylinder pressure and top hammer, reduces cost.
In the preparation process of the utility model product, the consumption of water glass of binder will suit, and generally is advisable with 1～5% of total amount, and consumption can impact the generation of diamond crystal too much; Consumption influences bonding effect very little again.
Implementation result example 1, in the synthesis of artificial diamond process, when making conductive heat insulation pressure transmission sheet with the pyrophyllite material, the synthetic required pressure of diamond is 1875～1885 tons on 2500 tons of belt type presses, synthetic required power is 6.10～6.15KW.When adopting the utility model, the synthetic required pressure of diamond is 1810～1820 tons, and synthetic required power is 5.75～5.80KW.
It is cylindrical to have provided being shaped as of conductive heat insulation pressure transmission sheet among the embodiment of the present utility model, also can make other corresponding shape according to actual needs, as square etc., just makes corresponding changes according to same principle, can make.
