Abstract
The kiln tools are made of cordierite (30-70 Wt.%), industrial alumina powder (10-35%), magnesic raw material (5-25), binding clay (12-30), microfine SiO2 powder (2-50) and inorganic adhesive (0.5-1.5), and feature high thermoshock stability and high-temp. bend strength.
Description
The present invention relates to the Mohrkete iolite kiln furnitures material that a kind of Mohrkete iolite kiln furnitures material, particularly fire porcelain are used.
Advanced ceramics industry forward is energy-conservation, high-quality, high yield direction develop, kiln furnitures to fire porcelain require harshness more, require kiln furniture material will have certain high temperature intensity, are difficult for flexural deformation, simultaneously, also should have thermal shock resistance and long characteristics such as work-ing life preferably.Present most high alumina cordierite, clay matter, high alumina matter of adopting of China's kiln furnitures, these kiln furniture materials, access times are few, and average about tens times, power consumption is high, and torsional deformation and influencing by the quality of burned product very easily in the use.Though the mullite cordierite is abroad arranged, and the kiln furniture material that recrystallized silicon carbide matter etc. are advanced can only satisfy some requirement of user, does not reach the unification of practicality, economy.
The objective of the invention is in order to adapt to the needs of ceramics development, the deficiency that remedies kiln furniture material provides that a kind of thermal shock resistance is strong, high-temperature bending strength is high, economy, the cordierite kiln furniture material that practicality is unified.
The object of the present invention is achieved like this: it by More Ke Te, commercial alumina powder, contain magnesium raw material, bonding clay, SlO
2Micro mist, inorganic bonding agent are formed.Each component content (weight %) is, More Ke Te 30-70, and commercial alumina powder 10-35 contains magnesium raw material 5-25, bonding clay 12-30, SlO
2Micro mist 2-50, inorganic bonding agent 0.5-1.5.
Purpose of the present invention can also reach by following measure: More Ke Te by mullite, contain the potassic glass phase composite, inorganic bonding agent is made up of phosphoric acid salt.The optimum value of above-mentioned each component content (weight %) is More Ke Te 35, aluminium sesquioxide 15, chlorite 25, clay 21.4, SlO
2Micro mist 2.5, phosphoric acid salt 1.1.
Below in conjunction with embodiment in detail the present invention is described in detail.
Material of the present invention by More Ke Te, commercial alumina powder, contain magnesium raw material, bonding clay, SlO
2Micro mist, inorganic bonding agent are formed.More Ke Te is added by mullite to contain potassium raw material synthetic.The potassium raw material that contains of the present invention refers to feldspar, contains the potassium clay.The present invention of commercial alumina powder can adopt aluminium oxide powder.The magnesium raw material that contains that the present invention uses is talcum powder and chlorite.Inorganic bonding agent adopts the high phosphoric acid salt of dispersity.
The physico-chemical parameter of each component is:
SlO
2Micro mist refers to all kinds of major-minor products, granularity≤0.1mm, SlO
2〉=85% fine powder.
Feldspar, contain potassium clay fineness≤0.05mm.
Phosphoric acid salt is powdery, and bonding clay is general clay.
Mullite and feldspar or the weight ratio that contains the potassium clay are 15: 1.
After above-mentioned raw materials stirred in proportion, burn till through 1300-1400 ℃ high temperature, optimum temps is 1380 ℃, 12 hours, is pressed into the refractory slab of 500 * 600 * 35mm then.Have following fundamental property:
0-1000 ℃ of thermal expansivity 2.6-3.3 * 10
-6/ K
Void content 20-30%
High temperature break resistant intensity (1250 ℃) 8-12MPa
Strength at normal temperature 15-20MPa
Load softening point 1390-1410 ℃
Optimum formula of the present invention is:
Prescription 1:(weight %)
More Ke Te 30, aluminium sesquioxide 20, chlorite 25, clay 21.4, SlO
2Micro mist 2.5, phosphoric acid salt 1.1.
Prescription 2:
More Ke Te 40, aluminium sesquioxide 13, chlorite 15, clay 25, SlO
2Micro mist 6, phosphoric acid salt 1.
Prescription 3:
More Ke Te 70, aluminium sesquioxide 10, talcum powder 8, clay 6, SlO
2Micro mist 4.5, phosphoric acid salt 1.5.
Compared to existing technology, the present invention has the following advantages:
1, thermal shock resistance is strong;
2, high-temperature bending strength height;
3, long service life is used＞300 times at health porcelain kiln (1250 ℃);
4, good energy-conserving effect.
