Abstract
The utility model discloses a pyrophillite piece heat preservation of ability self -constriction under high temperature high pressure state, dolomite layer including cyclic annular pyrophillite cavity and inside lining, pyrophillite cavity outer wall be equipped with outer cordierite layer, dolomite in situ layer be equipped with in the cordierite layer, outer, interior cordierite layer expose and be equipped with the magnesium oxide coating on the surface, pyrophillite cavity and outer cordierite layer between, dolomite layer and interior cordierite layer pass through water glass glue bond and be connected. Compared with the prior art, the utility model discloses a structure can reduce the inflation of pyrophillite cavity, and the effectual reduction synthesis temperature of ability reduces the synthesis pressure, increases the productivity to reducing cost consumption virtually, economic benefits is obvious.
Description
Technical field
The utility model relates to a kind of pyrophyllite block heat-insulation layer of energy self-constriction under high-temperature high-pressure state.
Background technology
Diamond fabrication industry diamond synthesizing mould used is pyrophyllite block, and pyrophyllite block mainly plays the effects such as sealing, pressure transmission, insulation.Suffered by pyrophyllite block inwall and synthetic rod connecting portion, temperature is the highest, can produce phase transformation under pyrophyllite block high temperature, uses dolomite material to do liner, play insulation effect so general.Refractory material at high temperature has certain coefficient of expansion, and when cubic hinge press pressurizes, inner dolomite outwards expands and can lose pressure.In fixing top hammer inclined design and pyrophyllite block dimensional configurations, synthetic cavity internal pressure is limited, even if raised pressure is also of no avail, and easily causes unnecessary cost consumption.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of pyrophyllite block heat-insulation layer of energy self-constriction under high-temperature high-pressure state.
The utility model is achieved through the following technical solutions:
A kind of pyrophyllite block heat-insulation layer of energy self-constriction under high-temperature high-pressure state, comprise the dolomite of ring-type pyrophillite cavity and liner, described pyrophillite chamber outer wall is provided with outer cordierite layer, described dolomite internal layer is provided with interior cordierite layer, described outer, interior cordierite layer exposed surface is provided with magnesium oxide coating, and between described pyrophillite cavity with outer cordierite layer, dolomite and interior cordierite layer bonded by water glass adhesive and be connected.
Compared with prior art, structure of the present utility model can reduce the expansion of pyrophillite cavity, can effectively reduce synthesis temperature, reduces synthesis pressure, and increase production capacity, and virtually decreasing cost consumption, economic benefit is obvious.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of pyrophyllite block heat-insulation layer of energy self-constriction under high-temperature high-pressure state, comprise the dolomite 2 of ring-type pyrophillite cavity 1 and liner, described pyrophillite cavity 1 outer wall is provided with outer cordierite layer 3, described dolomite 2 internal layer is provided with interior cordierite layer 4, described outer, interior cordierite layer exposed surface is provided with magnesium oxide coating 5, and between described pyrophillite cavity 1 with outer cordierite layer 3, dolomite 2 and interior cordierite layer 4 bonded by water glass adhesive and be connected.
This is novel utilizes the shrinkage ratio between unlike material and the inconsistent principle of the coefficient of expansion.
