Abstract
The present invention relates to a technology for producing press blocks of composite pyrophyllite-dolomite powder. The press blocks are made from the raw materials of pyrophyllite and dolomite which are pulverized, sieved, mixed, stirred, sealed, stored, molded, pressed, dried and cooled. The press blocks have the advantages of low resultant current, low resultant pressure, low top hammer consumption, good repeatability and stable production, and eliminate a gap between a dolomite pipe and the pyrophyllite. Diamond made from the press blocks has the advantages of good quality, pure color, no bubble, good crystal form, high transparency, few impurities, no generation of black particles and obvious improvement of economic benefits, so that the press blocks are ideal materials which are used for producing the diamond and are warmly welcomed by users.
Description
The present invention relates to a kind of manufacturing process of pyrophillite dolomite composite powder briquetting, relate to a kind of manufacturing process specifically pyrophillite and white clouds madreporic canal, powder pressure ring combined pressure pyrophillite dolomite composite powder briquetting together.
At present, along with the fast development of national economy, market competition is also more and more fierce, and people are also more and more higher to the requirement of various product qualities.Especially more and more higher to the requirement of synthesis of artificial diamond quality, people require the synthesis of artificial diamond color pure, no bubble, and crystal formation is good, the transparency height, impurity is few, does not have black particle to produce.And existing for the briquetting that the cubic apparatus synthesis of artificial diamond is specially pressed and insulation is worth, be generally two kinds: a kind ofly be the briquetting of pure pyrophillite piece; Another kind of for adding the briquetting of white clouds madreporic canal, still, the briquetting that adds the white clouds madreporic canal is too many because of its annex, assembling is complicated, and the gap is too big, the top hammer consumption height, economic benefit is low, so the existing briquetting that adds the white clouds madreporic canal is still not ideal enough to producing diamond, does not have the value of promoting and using.
The object of the present invention is to provide a kind of manufacturing process,, overcome the deficiencies in the prior art to improve its use value with pyrophillite piece and white clouds madreporic canal, powder pressure ring combined pressure pyrophillite dolomite composite powder briquetting together.
The object of the present invention is achieved like this: it is made up of pyrophillite and dolomite raw material, forms through pulverizing, sieve, mix, stir, seal up for safekeeping, go into mould, compacting, baking, cooling, it is characterized in that manufacturing process is as follows:
1. pyrophillite is pulverized, crossed the 10-40 mesh sieve, get pyrophyllite powder, promptly get the raw material of pyrophillite piece, standby,
2. dolomite is pulverized, crossed the 80-120 mesh sieve, get dolomite dust, promptly get the raw material of white clouds madreporic canal, standby,
3. pyrophillite is pulverized, crossed the 40-100 mesh sieve, get the raw material of powder pressure ring, standby,
4. above three kinds of standby raw materials are stirred by following percentage by weight proportion liquid sodium silicate (being called for short sodium metasilicate later on) between 50-52 respectively and 20 ℃ the time,
Sodium metasilicate 6% pyrophyllite powder 94%
Sodium metasilicate 10% dolomite dust 90%
Sodium metasilicate 10% pyrophyllite powder 90%
5. with above-mentioned three kinds of raw materials that stir, seal up for safekeeping more than 24 hours with bucket respectively,
6. again with the above-mentioned raw material of sealing up for safekeeping, put into pipe mold and ring mould respectively, be pressed into the white clouds madreporic canal, be made into the powder pressure ring with 5 tons of stampers with 25 t hydraulic press,
7. make the composite powder briquetting,
A, make the composite powder briquetting of band step: during making, in mould, put the powder pressure ring earlier, after put
The white clouds madreporic canal,
B, make not composite powder briquetting: during making, in mould, put the powder pressure ring earlier, again with step
Put the white clouds madreporic canal, after put the powder pressure ring,
8. the hydraulic press with the 40-60 ton is pressed into the cubic block that has through hole with white clouds madreporic canal and powder pressure ring,
9. with infrared oven baking 6 hours, wherein keep 100 ℃ 2 hours, 200 ℃ 3 hours, 250 ℃ 1 hour, cooling naturally in baking oven, 50 ℃ are taken out and pack, and promptly get pyrophillite dolomite composite powder briquetting of the present invention.
The present invention compared with prior art utilizes its resultant current low, and synthesis pressure is low more than the form at 2-10, at 30kg/cm
2About, top hammer consumption is low, about 20-30%, good reproducibility has been eliminated the space between white clouds madreporic canal and the pyrophillite, produces stable, the diamond quality that uses it to produce is good, and color is pure, no bubble, crystal formation is good, the transparency height, and impurity is few, there is not black particle to produce, economic benefit obviously improves, and is that a kind of desirable diamond that receives praises from customers is produced material, has higher promotion and use value.
