Abstract
The utility model provides a compounded pyrophyllite block for the filed of metallurgy technology; the utility model is mainly characterized in that the inner wall of a pyrophyllite sleeve is embedded with a sleeve-shaped liner tube formed by prepressing dolomite and graphite; the pyrophyllite block out of the liner tube is formed by packing and compound pressing two semi-sleeve pyrophyllite blocks. The dolomite powder and the graphite are mixed with a weight proportion of 100:2, and the NaSO4 solution of ( 6 plus 0.6) percent is added, finally, the liner tube is produced by prepressing; moreover, the pyrophyllite powder is mixed according to thick, medium and thin weight proportion of 8:15:7, and the NaSO4 solution of ( 6 plus 0.6) percent is added, finally, the pyrophyllite block is produced by prepressing. Compared with the prior art, the compound pyrophyllite block not only can solve the phase change problem in high pressure and high temperature, but also have perfect heat preservation, pressure transferring and sealing effect, and the utility model is good for the long-time synthesis of high-quality diamond, as well as reduces the hammer consumption.
Description
Technical field:
The utility model belongs to the synthetic facility technology field of diamond, is a kind of compound pyrophyllite in lumps.
Background technology:
Pyrophillite is the requisite transmission medium of diamond synthesis on the cubic hinge press, and the formation of high temperature, high-pressure chamber is left it and can't be realized, its main effect is sealing, pressure transmission, insulation, insulation and support.Traditional pyrophyllite in lumps is by single pyrophyllite ore, after cleaning, being broken into different grain size, sieving out carse, medium and small three kinds of granularities, allotment and NaSO4 solution mix vexed the putting 24 hours in back by a certain percentage, top die guarantees to be pressed into the pure pyrophyllite in lumps that different cavitys need, and promptly can be used for assembling, synthetic through roasting again.This traditional pyrophyllite in lumps satisfies the synthetic usefulness of hanging down the product grade diamond of slice catalyst substantially.But along with the development of diamond industry, pure pyrophyllite in lumps can not satisfy the needs of the long-time synthesis technique of high grade diamond, weak point mainly contain following some:
1, under high temperature, high pressure, the pyrophyllite crystallization water impels pyrophyllite to be phase-changed into kyanite, Ke Yingshi, and the heat-insulating property of pyrophyllite, the equal variation of pressure transmission performance, thus synthetic cavity diamond film environment is offset, cause diamond internal soundness instability.
2, along with synthesis technique time lengthening, the phase change layer thickness of pyrophyllite cavity internal layer thickens, and the pyrophyllite sealing property is weakened, and the probability of split hammer, blowing out increases, and the top hammer consumption amount increases.
3, pyrophyllite is direct contacts with synthetic post in the cavity, and the crystallization water pollutes the diamond film environment, and the diamond underbead crack is increased, and has hoary hair's diamond to generate.
Summary of the invention:
The purpose of this utility model provides and a kind ofly can improve the diamond internal soundness, stablizes phase change layer and insulation, pressure transmission, good seal performance, is beneficial to the synthetic NEW TYPE OF COMPOSITE pyrophyllite in lumps of long-time high grade diamond.
Realize that the technical scheme that the purpose of this utility model is taked is improved on the basis of original sleeve shaped pyrophyllite in lumps,, be nested with bushing pipe at pyrophyllite sleeve inwall.This bushing pipe becomes sleeve shaped by dolomite, graphite precompressed; The outer pyrophyllite in lumps of bushing pipe is compositely suppressed to form by two and half sleeve pyrophyllite in lumps cover bag, and bushing pipe is by dolomite dust, graphite, and the weight portion proportioning by 100: 2 adds (6+0.5) %NaSO4 solution, and precompressed forms; Pyrophyllite in lumps by carse, medium and small 8: 15: 7 weight portion proportioning, adds (6+0.5) %NaSO4 solution by pyrophyllite in powder, and precompressed forms.
The compound pyrophyllite in lumps of making according to such scheme, can not only solve the phase transformation problem under high pressure, the high temperature, and obviously be better than pure pyrophyllite in lumps at aspect of performances such as insulation, pressure transmission, sealings, be beneficial to the synthetic of long-time, high grade diamond, simultaneously, reduced top hammer consumption, drawn stone to compare with pure leaf, myriagram draws hammer consumption decline 2～3Kg.Use this compound pyrophyllite in lumps, adamantine internal soundness is improved greatly, crackle, bubble reduce, and can stop the adamantine generation of hoary hair.
Utilize accompanying drawing to further describe embodiment of the present utility model below;
Description of drawings:
Fig. 1 is a general assembly structural representation of the present utility model;
The specific embodiment:
Compound pyrophyllite in lumps of the present utility model has the pyrophyllite in lumps 1 that overlaps tubular, at pyrophyllite sleeve inwall 5, is nested with bushing pipe 2.This bushing pipe 2 becomes sleeve shaped by dolomite, graphite precompressed, bushing pipe 2 outer pyrophyllite in lumps 1 are compositely suppressed to form by two and half sleeve pyrophyllite in lumps upper and lower sleeve bags, wherein, pyrophyllite in lumps 1 is by carse, medium and small 8: 15: 7 weight portion proportioning by pyrophyllite in powder, add (6+0.5) %NaSO4 solution, batch mixing 20 minutes, vexed putting 24 hours, the moon screen cloth that dries in the air, sieves is 10 orders; Bushing pipe 2 is by dolomite dust, graphite, by 100: 2 weight portion proportionings, adds (6+0.5) % NaSO4 solution, batch mixing 15 minutes, and vexed putting 24 hours, the screen cloth that dries, sieves is 12 orders; At last, with half of compound pyrophyllite total amount, pack in the pyrophyllite in lumps pressing mold, shake up, the dolomite liner sleeve is contained on the core rod, be press-fit into place with the location gland, rolling is put down after reinstalling second half pyrophyllite, puts into seaming chuck, the start compacting, pressurize retreated mould in 3 seconds, can obtain required compound pyrophyllite in lumps.
