A kind of preparation method of gem type Sharipu
Technical field
The invention belongs to experimental science field.
Background technology
After humans and animals is cremated, the main component of remaining bone ash is calcium phosphate, and its microstructure is the fluffy state in many holes, if meeting the environment of humidity, then easily by the moisture absorption in air, the time one is long, and microorganism or antibacterial will take advantage of the occasion to corrode, pollute bone ash, allow bone ash go bad, produce abnormal flavour.
The bone ash of powdery itself is not easy to preservation, once be landed by dispelling, it is difficult to recover.For to the respect of ghost with cherish the memory of, people collect at home after generally putting it into cinerary casket, but this always contradicts with the decorative effect of modern house again.
In order to solve the problems referred to above, there is Crinis Carbonisatus to understand a kind of " manufacture method of Buddhist bone relic product ", and applied for patent (patent No.: 200910010807.2).This invention is dead ash, crystal and goods and silicate metal to develop the color abrasive lapping to 200-300 order;Grinding human bone ash, the wet base of Buddhist bone relic product is made in the kneading that adds water mold pressing, drying, add silicate metal colour developing material spraying dipping, dry, preheating, then through sintering, be slowly cooled to room temperature the upper picture of printing and admonition under 1300 DEG C of oxidizing conditions;Qualified it is Buddhist bone relic product through checking.
This Buddhist bone relic product solves bone ash and goes bad and be difficult to the problem collected, but its quality is bright not, and the china of similar thick glaze, less attractive, collection is intended to also not high, it is difficult to flatter into the exquisite ornaments interspersing household, dress ornament, artware.
In Korea S, Crinis Carbonisatus is had again to understand the patent (patent announcement number: KR20100108503) of " method manufacturing Sharipu with bone ash ".The purpose of this invention, there is provided a kind of method by mankind's bone ash to manufacture crystalline material, the variously-shaped artificial crystal material formed by the method, has the color as sapphire or old jade.Making step is: the dispensing of dead ash, by weight 60-70, mica sheet 15-20, Gypsum Fibrosum powder 10-20, Maifanitum 5-15, these mixture are cast in mould and fashion into spherical, oval or beans shape, melting 1 hour 20 points in the electric furnace of 1000-1500 DEG C Celsius again, after cooling, it is artificial crystal material.
This beautiful artificial crystal material as matter, brighter than the quality of the Buddhist bone relic product of thick glaze china type, but it is such Sharipu will to be made the gem that can appear glare color, melting can only be carried out at present, it is important to allow main in dispensing, to be most difficult to again fusing silicon crystal be warming up to liquefaction state, then add Qinghua agent, coloring agent with the synthetic cut stone glass furnace of specialty, clarified, homogenizing, discharge the foreign gas through chemolysis and physical vapor, finally cool down, make cameo glass.
But when the main equipment of such tonnage level, it is used for making a small amount of Sharipu technology and does not still become reality, not only valency high energy consumption is big, and the bone ash consumption often driving a stove wants big accordingly, need numerous human or animal's bone ash blendings just can be made into equivalent together, this, for Sharipu, has again impure, respectful meaning.
Summary of the invention
The concrete grammar realizing the present invention is: dispensing used by gem type Sharipu includes: granularity is the rare earth compound (CeO of 325 order-400 mesh sieve screenings2/Co2O3/ Co2O) 0.1-0.5wt%, quartz sand (SiO2) 20-25wt%, bone ash (Ca3(PO4)2) 56-59wt%, dolomite dust (CaCO3) 0.3-1wt%, Borax (Na2B4O7·10H2O) 0-0.5wt%, natural ore powder (BaSO4/CaO·Al2O3·6SiO2) 0-1wt%, chemical pure lead oxide (B2O3) 3-5wt%, potassium oxide (K2O) 1-2-wt%, with waterglass (the Na2O nSiO of 0.5-1 (1Pa.s) viscosity2) after 5-10wt% is blended into base mud, be placed on again in graphite template, enter 0:10-0:15min in enameling furnace, drying, be preheated to 250-300 DEG C after, it is incubated 0:05min again, then change to experimental furnace while hot, experiment furnace temperature is slowly increased to 1500-1600 DEG C, heating-up time 1:10-1:40min, keep 0:20min again, adopt the high up in the air method melting erected in furnace tank interlayer of base mud template simultaneously, last natural cooling, gem type Sharipu.
Wherein adopt base mud template smelting equipment of erecting high up in the air in furnace to be: a kind of gem type Sharipu prepare stove, burner hearth is provided with interlayer, become with shelf pin bank by graphite template, shelf pin is 1 layer 4, including 2, the left side and 2, the right, 2, this left side shelf pin is inserted in burner hearth left wall with being respectively perpendicular, and 2, the right shelf pin is inserted on the right wall of burner hearth with being respectively perpendicular, and every layer of 4 shelf pins position are put and kept symmetrical;It is characterized in: described interlayer adds and is set as 2-5 layer, between each interlayer, keeps plane-parallel;Thickness >=1cm≤the 4cm of described graphite template;The cross section of described shelf pin is that rectangle is circular or oval;Described cross section is the outer surface corner angle of rectangle is circular arc chamfering shape, the radius >=0.5cm of chamfering.
The present invention solves the problem that Sharipu quality is mentioned the more high grade of transparency and hardness preferably.
The present invention also solves the problem that can improve work efficiency and function in identical experiment stove preferably.
This invention address that its technical problem adopted ground technical scheme be: the sand material (except chemical pure) in Sharipu dispensing used, all adopt 325 orders and the granularity of 400 orders combination sieve screening, mix rare earth compound, melting furnace temperature is brought up to 1500-1600 DEG C, and is placed in furnace tank interlayer the method melting erected high up in the air by the template of base mud.
The invention has the beneficial effects as follows: when identical experimental furnace, better gem type Sharipu quality can be clarified, homogenizing, toning, bone ash and impurity is made can successfully to gasify effusion, reduce impurity gem type Sharipu within, while can also improve the yield of gem type Sharipu or share 1-5 times.
Preferred as one, gem type Sharipu sand shape dispensing used is 325 orders and the granularity of 400 orders combination sieve screening.
The sand grains diameter of 325 orders is 0.045mm, and 400 purposes are 0.037mm, and 300 purposes are 0.05mm.
Because the quartz (SiO of mineral aggregate2) fusing point is 1710 DEG C, according to burn-off rate constant (τ) formulaIn it can be seen that (k1) be glass ingredient molten temperature constant, Bu Huibian;And cube being inversely proportional to burn-off rate constant (τ) of the quartzy radius (r0) of sand grains, so quartz sand grains is more thin, burn-off rate reaction is more fast, temperature required also more low, is typically in 1300-1500 DEG C;But, when the granule of quartz sand or other sand shape material is directly through < 0.006mm, i.e. powdering, the silica flour periphery of partial amt can too fast heat multiviscosisty, become bulk bulky grain by sealed knot, this not readily dissolves on the contrary, form internal dross, affecting Sharipu quality, and easily cause powder to fly upward during powder operation, it is so adopting the combination sieve of 325 order-400 orders.
Preferred as one, dispensing has rare earth compound.
The quality of the gem type Sharipu of the present invention wants transparency, is not by the conventional chemical reaction in glass manufacture stove like that, mixes sufficient Natrii Sulfas (Na2SO4·10H2O) ratio is clarified, homogenizing, the raising thermal efficiency, because Natrii Sulfas is easily damaged stove brick after meeting high-temperature gasification, but mainly by expensive, but the rare earth compound that relative usage is little.Rare earth compound has homogenizing, integrates the function of molecular structure, not only instead of the effect of Natrii Sulfas, and furnace temperature when making to be melt into liquefaction state can relative reduction, also improve intensity and the hardness of gem type Sharipu quality.It is demonstrated experimentally that rare earth compound is in processing technology process, the combination sieve of granularity 325 and 400 order is adopted to be preferred.
It addition, rare earth compound can also adjust color, for instance: add the cobalt oxide (Co of trivalent2O3) after silicon crystal in blueness;Add the cobalt oxide (Cu of tetravalence2O) take on a red color after;Add cerium oxide (CeO2) it is then decolorising agent, silicon crystal can be allowed to become light yellow green from aeruginous.
Preferred as one, experimental furnace furnace temperature is brought up to 1500-1600 DEG C and carries out melting.
Because the various impurity gasification allowed as much as possible in melting in Sharipu in silicon crystal is discharged, but the molten temperature of some natural impurity is higher, such as: barite (BaSO4) molten temperature 1580 DEG C;Anhydrite (CaO Al2O3·6SiO2) molten temperature 1550 DEG C;Deng, only reach 1600 DEG C of these temperature, silicon crystal liquation could be allowed rarer thick, reach the laminar flow effect to turbulent flow, thus promoting the impurity vaporization effusion of system point;Can to the homogenizing of crystalline solid inner structure, integration plus rare earth element, also catalytic impurities gasification, goes back relative reduction smelting temperature.
Preferred as one, when testing melting in burner hearth, also adopt and allow the template of Sharipu base mud be placed in burner hearth the method for smelting erected high up in the air.
Make us outside prediction: put furnace tank interlayer into what graphite template did not land, not only make use of the space in burner hearth, energy multilamellar puts the template of Sharipu base mud, increase yield, graphite template also can be allowed to become the heating effect of three-dimensional position fire up and down at freeze profile, reduce because of bottom Sharipu with the temperature difference of surface liquation, make bottom fluid layer not remain in a standstill, can rise fully and chemically and physically react, allow depositing contaminants gasification overflow.
Preferred as one, in experiment burner hearth, it is provided with one group of interlayer, graphite template becomes with shelf pin bank.
This template putting Sharipu base mud is the graphite template of nano fabrics, is resistant to the high temperature of 3000 DEG C.It is that shelf pin bank becomes owing to putting the shelf of graphite template, the shielded area of graphite template reverse side is few, so the intensity of a fire below graphite template is still fierce.That sets up in melting burner hearth that 1-5 layer keeps plane-parallel puts template pin, can soar aloft to shelve the graphite template of 1-5 layer, say, that can also improve the yield of Sharipu or share 1-5 times simultaneously.Additionally, this multilamellar template is the method for smelting erected high up in the air in furnace tank interlayer, it is thus also avoided that the touch opportunity of Sharipu and stove brick, especially uppermost one layer, the oxide skin(coating) foreign material on stove brick can be blocked and arch drips, the foreign material that come off of zircon liquation etc., it is ensured that the quality of all lower floors Sharipu.
Preferred as one, the thickness (4) of graphite template >=1cm ,≤4cm.
Crossing thin graphite template easy fracture in high temperature cooling process, the blocked up heat that can affect again is transmitted.
Preferred as one, keep plane-parallel between each interlayer.
Gem type Sharipu temperature of melting in stove of the present invention is 1500-1600 DEG C, and it is aqueous for can making the silicon crystal in Sharipu, if not keeping plane-parallel between each interlayer, silicon crystal solution can be made to overflow graphite template, destroy and make achievement.
