Description
Technical field
The invention belongs to refractory material saggar field, more particularly to a kind of modified form saggar and preparation method thereof.
Background technology
Saggar is one of kiln furnitures.During firing ceramics device, to prevent gas and harmful substance from being broken to base substrate, glaze
Go bad and be stained, ware and base substrate are placed in the container that refractory material is made and are calcined, this container is to claim saggar, also known as casket
Son.
Using saggar firing ceramics device, can not only improve dress burning amount, product 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, it is different according to implements shape.China dragon
The eggshell black pottery that mountain culture period fires, using 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 earliest saggar.The saggar that later age finds, 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 fewer in the use of Domestic ceramic enterprise as supporting body.But casket
Alms bowl is still very universal in the application of ceramic pigment enterprise as charge vessel, in recent years, due to raw material, fuel, artificial etc.
Cost is risen steadily, and the price of saggar is also increased substantially, despite this, the service life of saggar is but in reduction, saggar makes
With breakage rate per kiln up to 16~22%, the serious wasting of resources and economic loss are caused.Saggar access times how are improved, are dropped
Low saggar uses breakage rate, reduces solid waste discharge, improves the performance of enterprises, be present urgent problem to be solved.
The content of the invention
The technical problems to be solved by the invention are the above-mentioned technical problem present in existing saggar and provide one
Plant service life length, modified form saggar of light weight and preparation method thereof.
The technical problems to be solved by the invention can be achieved through the following technical solutions：
A kind of modified form saggar, it is prepared from by the raw material of following parts by weight：Magnesia 10~13 parts of mud, black talc 10~
12 parts, 33~35 parts of fire clay, old 10~12 parts of sand, 4~6 parts of ballstone, 4~6 parts of aluminium powder, 5~7 parts of bauxite, fine purifiation mud 17
~19 parts, 90-160 parts of mullite, 22-35 parts of cordierite powder, 8-12 parts of attapulgite, 8-12 parts of calcined kaolin.
In a preferred embodiment of the invention, the modified form saggar is prepared from by the raw material of following parts by weight：
Magnesia 11.22 parts of mud, 10.21 parts of black talc, 34.15 parts of fire clay, old 11.18 parts of sand, 4.65 parts of ballstone, 4.23 parts of aluminium powder,
6.24 parts of bauxite, 18.12 parts of fine purifiation mud, 122 parts of mullite, 25 parts of cordierite powder, 9 parts of attapulgite, calcined kaolin 9
Part.
The preparation method of above-mentioned modified form saggar, comprises the following steps：
1) will each raw material mix after carry out forming powder after wet ball grinding, ball milling that to cross 60 mesh sieves standby；
2) pressed compact is molded, and powder after ball milling is molded through granulation, pressed compact, compressing under 60Mpa pressure, insulation 2.5
Hour, the demoulding obtains saggar body；
3) by base substrate pre-burning at 500-600 DEG C, water quenching is then carried out, base substrate is quickly put into water, the time is 22-
35s；Then the base substrate after water quenching is put into 50-60 DEG C of oil, oil cooling 22-35s；
4) base substrate after processing is dried into 10-22h under field conditions (factors), is put into kiln and is burnt till, firing temperature is
1160-1350 DEG C, firing time is 10-16 hours.
As a result of technical scheme as above, the present invention is constituted by optimizing the raw material of saggar, to improve the heat of saggar
Stability, anti-pressure ability, corrosion resistance and the performance such as not easy to crack so that saggar has service life long, light weight it is excellent
Point.The raw material that the present invention is used is cheap, and the simple environmental protection of preparation technology can industrializing implementation.
