Description
Technical field
The invention belongs to refractory material saggar field, be combined the preparation method of saggar particularly to a kind of mullite-corundum.
Background technology
Saggar is one of kiln furnitures.During firing ceramics device, for preventing gas and harmful substance from breaking base substrate, glaze
Going bad and being stained, ware and base substrate are placed on roasting in the container that refractory material is made, this container i.e. claims saggar, also known as casket
Son.
Use saggar firing ceramics device, not only can improve dress burning amount, goods and will not bond, improve yield rate, and saggar
Also there is certain thermal conductivity and heat endurance, it is ensured that ceramic mass.The shape of saggar, different according to implements shape.China dragon
The mountain culture eggshell black pottery fired in period, has used special saggar.Once gathered in Shandong Province Zhucheng poplar home ruins
Two pieces fires the saggar of Longshan culture egg-shell pottery, and this is current known saggar the earliest.The saggar of discovery later age, to contain porcelain
Based on, Sui Dynasty Hunan kiln it has been found that.
With the application of clean energy resource, saggar is fewer and feweri in the use of Domestic ceramic enterprise as supporting body.But casket
Alms bowl is as charge vessel, still very universal in the application of ceramic pigment enterprise, in recent years, due to raw material, fuel, artificial etc.
Rising steadily of cost, the price of saggar also increases substantially, despite this, the service life of saggar is but reducing, saggar makes
Reach 15～20% with the every kiln of breakage rate, cause the serious wasting of resources and economic loss.How to improve saggar access times, fall
Low saggar uses breakage rate, reduces solid waste discharge, improves the performance of enterprises, be present problem demanding prompt solution.
Mullite-corundum is combined the one that saggar is the more hot topic of research now and is combined saggar, as CN103482993A is public
A kind of corundum, mullite composite material saggar and preparation method thereof are opened；Described saggar with fused white corundum, electrofused mullite,
Andalusite, sillimanite, a-aluminum oxide, fine silica powder, kaolin are raw material, become through Mold Making, blank mixing, green compact
Type, green compact integer, drying, high-temperature firing form, and also need to carry out machinery fine grinding further before finished product warehouse-in.The casket that the present invention makes
Alms bowl contains electronic devices and components half base during being mainly used in Electronic Components Manufacturing, during high-temperature firing, keeps stable
Electric property.Compare 95 porcelain saggars of original use, there is good shaking property of heat and erosion resisting and further increase electricity
The electric property of sub-components and parts, saggar brought up to six months from two months service life；Described saggar alumina content relatively low and
Manufacturing process changes so that manufacturing cost greatly reduces compared with 95 porcelain saggars；Utilize the saggar that the present invention makes for these reasons
Obtain the consistent accreditation of electronic devices and components producer, progressively instead of 95 porcelain saggars of original use.
Present invention mainly solves technical problem is that: for the deficiencies in the prior art, provides a kind of mullite-corundum to be combined
The preparation method of saggar, is combined the raw material composition of saggar, uses mullite and corundum as master by optimizing this mullite-corundum
Raw material, with albite, wollastonite, talcum, fused magnesite, red mud, zirconium silicate, silicon nitride and reinforcing fiber as auxiliary material, meanwhile,
In preparation process, use shrend, oil cooling and aftertreatment technology, improve the physical and chemical performance of prepared product, prepared saggar heat
Good stability, anti-pressure ability is strong, corrosion-resistant and not easy to crack.
Content of the invention
It is an object of the invention to, for the problems referred to above, develop a kind of mullite-corundum and be combined the preparation side of saggar
Method.
A kind of mullite-corundum is combined the preparation method of saggar, including following preparation process:
1) preparing mullite-corundum and being combined saggar raw material, the raw material of this saggar consists of: mullite 90-140 part；Corundum
Powder 20-30 part；Albite 8-10 part；Wollastonite 8-10 part；Talcum 8-10 part；Fused magnesite 1-8 part；Red mud 1-3 part；Zirconium silicate
1-3 part；Silicon nitride 1-3 part；Reinforcing fiber 1-3 part；
2) carrying out wet ball grinding after mixing each raw material, forming powder after ball milling, to cross 100 mesh sieves standby；
3) pressed compact shaping, by powder after ball milling through granulation, pressed compact shaping, compressing under 50Mpa pressure, insulation 2 is little
When, the demoulding, obtain saggar body；
4) by base substrate pre-burning at 500-700 DEG C, carrying out shrend subsequently, quickly putting into base substrate in water, the time is 20-
30s；Subsequently the base substrate after shrend is put in the oil of 50-60 DEG C, oil cooling 20-30s；
5) base substrate after processing is dried 10-20h under field conditions (factors), puts into kiln and burns till, and firing temperature is
1100-1300 DEG C, firing time is 10-15 hour；
6) it is combined saggar to the mullite-corundum after burning till to post-process, cuts some dilatation joints in side, swollen
Fill in ceramic wool at expansion joint (E.J.), mullite-corundum can be obtained and be combined saggar.
As preferably, the raw material of this saggar consists of: mullite 120 parts；Schmigel 25 parts；Albite 9 parts；Wollastonite 9
Part；9 parts of talcum；Fused magnesite 2 parts；Red mud 2 parts；Zirconium silicate 2 parts；Silicon nitride 2 parts；Reinforcing fiber 2 parts.
As preferably, step 4) for by base substrate pre-burning at 600 DEG C, carry out shrend subsequently, quickly put into base substrate in water,
Time is 25s；Subsequently the base substrate after shrend is put in the oil of 55 DEG C, oil cooling 25s.
As preferably, step 5) it is dried 15h under field conditions (factors) for the base substrate after processing, put into kiln and burn
Becoming, firing temperature is 1200 DEG C, and firing time is 12 hours.
The present invention is also claimed a kind of mullite-corundum and is combined saggar, it is characterised in that: it uses above-mentioned not coming
Prepared by the preparation method that stone-corundum is combined saggar.
Beneficial effects of the present invention:
Generally speaking, it is combined the composition of saggar by optimizing mullite-corundum, improve heat endurance, the resistance to compression of saggar
Ability, corrosion resistance and the performance such as not easy to crack；Traditional on the basis of the raw material of mullite and corundum, select
The composition of mullite is more than schmigel with the amount of about 3-7 times, so that the compressive resistance of base substrate is greatly improved；With
When, in the selection of auxiliary material, albite, wollastonite, talcum and fused magnesite and a small amount of silicon nitride can not only play increasing
Strong raw material anti-pressure ability and thermostable effect, meanwhile, in raw material sintering process, its not only with major ingredient phase reaction, reduce glass
Glass phase, meanwhile, optimizes sintering process so that prepared base substrate has more preferable consistency and heat endurance；And by adding
Enter the compound binding agent of red mud and zirconium silicate, improve binding ability and the plasticity of prepared saggar；And a small amount of increasing
Strong fiber is by forming horizontal shearing force between raw material, for the anti-pressure ability improving product and equivalence fruit not easy to crack
There is very important impact.
And for preparation technology, the present invention, on the basis of traditional preparation technology, opens up new employing pressed compact-water
Quench-oil cooling-and burn till-cut the techniques such as dilatation joint, by the sufficient inherent strain eliminating product, reduce its thermal coefficient of expansion,
Overall preparation technology is simple, but but produces great raising for the performance optimizing product.Prepared saggar compression strength
More than 15MPa, use continuously and still will not crack at least 15 times.
The cheaper starting materials that the present invention uses, the simple environmental protection of preparation technology, can industrializing implementation.
