Description
Technical field
The invention belongs to refractory material saggar field, particularly to the preparation method of a kind of compound saggar.
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 16～22% 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.
Compound saggar is that the one of the more hot topic of research now is combined saggar, such as CN104692812A ternary material lithium
The preparation method burning saggar contained by battery, using mullite synthesizing as major ingredient, accounts for the 70% of the total proportioning of quality, makees synthesis of dichroite
For major auxiliary burden, and add wax intermixture, account for the 30% of the total proportioning of quality；Major ingredient and major auxiliary burden are passed sequentially through and prepares sand powder
Device carries out particle and pulverizes and grating, and then by being previously charged into the mixed pulp device of wax intermixture, mixing and stirring is complete
Become the preparation of product idiosome slurry, then by shaped device stir further, extracting vacuum, discharge bubble and be cooled to
Type, is then discharged the composition of wax intermixture in product idiosome, is then entered product idiosome by sintering equipment by de-waxing device
Row sintering, then carries out surfaces externally and internally process by surface processing device to product idiosome, is finally dried process again, finally
Can be derived that ternary material lithium battery is contained and burn saggar.The technical scheme that the present invention provides can effectively reduce saggar cost, improves and produces
The quality of product and life-span.
Present invention mainly solves technical problem is that: for the deficiencies in the prior art, provide the preparation of a kind of compound saggar
Method, is formed by optimizing the raw material of this compound saggar, uses mullite and cordierite as main material, with attapulgite, forge
Burning kaolin, diopside, fused magnesite, red mud, nano-aluminum hydroxide colloidal sol, silicon powder and reinforcing fiber is 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 the preparation method of a kind of compound saggar.
A kind of preparation method of compound saggar, including following preparation process:
