Abstract
A kind of sintering method of infrared radiant material is a feature with the material composition.At least contain zircon sand 26-70%, ferric oxide 3-7%, chromic oxide 4-7%, Suzhou potter's clay 23-33%, lapis amiridis 27-41%, cobalt oxide 1-5% in the powder raw material, again and go into 10-13% clear water aftershaping, after 1150-1350 ℃ of sintering form.
Its emittance of this material is more than 0.88, and secondary is not cracked repeatedly to be chilled to 20 ± 5 ℃ from 650 ℃, and the life-span is longer.
Description
The present invention is in International Patent Classification (IPC) (the 5th edition), and belonging to the composition is the ceramic shaped articles of feature, the classification range of ceramic composition.
Radiator is the core of well heater, warmer.Its material composition has determined indexs such as its infrared emittance and hot cold sudden turn of events stability.National standard requires the emittance of infrared device more than 0.83.Institute of the Chinese Academy of Sciences technology of selling-polycrystalline mineralising black ceramic, with zircon sand, silicon carbide, ore deposit iron powder, titanium-iron powder etc. as main component.It is introduced, the radiative material that utilizes this prescription to make, its infrared emittance 〉=0.9, from 650 ℃ be chilled to 20 ℃ repeatedly three times not cracked, working life reached more than 20000 hours.Know that simultaneously this institute has applied for patent of invention (accept, but do not announce) to Patent Office of the People's Republic of China.Assign during technology implementation by above-mentioned, earlier raw material is mixed and stir into chemical paste, put, advance klining system then if in a hour aftershaping., burn till product and former base is far from each other, become the scum shape, can't assemble, more can not use.Several times test all fails.
Task of the present invention provides a kind of sintering method of infrared emission material, mainly is to determine its raw material composition prescription, makes its infrared emittance greater than national standard, promptly 〉=0.83.
Task is to realize like this.
Get the raw materials ready by following prescription requirement.Earlier powder raw material is mixed, sieve and stir evenly and the clear water of going into powder weight 10-13% mixes and stirs, make granule then, with this granule compression molding; After dry in the shade, repaired biscuit, sintering and obtain finished product.
Major ingredient is as follows at least:
Zircon sand 26-30%; Ferric oxide 3-7%;
Chromic oxide 4-7%; Suzhou potter's clay 23-33%;
Lapis amiridis 27-41%; Cobalt oxide 1-5%.
According to the infrared radiant material that the present invention program makes, sample measured result 2.5-20 μ m section ε in the time of its infrared emittance 〉=0.88(600 ℃
N1=0.88; 4-20 μ m section ε
N2=0.90; 5-20 μ m ε
N3=0.91); Be chilled to 20 ± 5 ℃ from 650 ℃, secondary is not cracked repeatedly; Working life is more than 20000 hours.
With example, its implementation method is described with the radiator (be commonly called as and be case) of lamp shape electric heating infrared radiation warmer below.
Get 200 order zircon sands 28%, 200 order ferric oxide 5%, 200 order chromic oxide 4%, 300 order Suzhou potter's clay 28%, 120 order lapis amiridiss 33%, 300 order cobalt oxides 2%, mixing together, sieve with 100 order nylon mesh, with the clear water of going into above-mentioned powder weight 13%, stir three times, make blank granule (for example on 24 order iron sieves, wipe) again, put it into and leave standstill 24 hours in the encloses container with blank.Use this blank granule compression molding then, get former base.This former base is through drying in the shade, being put into loading of kiln sintering in the fire-resistant alms bowl that is covered with thick quartz sand behind the repaired biscuit, and sintering temperature is 1150-1350 ℃.In 20 cubic metres the kiln of falling the cigarette, when being warmed up to about 500 ℃, kept about 8 hours, be raised to 1150-1350 ℃ then, kept the nature of ceasing fire at last cooling, air blast cooling kiln discharge after general 48 hours about 64 hours.
The method for making of the material composition of other radiatoies and technology and above-mentioned case is basic identical, and the key distinction is the mould and the demoulding.
Claims (3)
1, a kind of sintering method of infrared radiant material mainly is the composition of raw material, with the powder raw material mixing, sieve after and go into clear water and make granule, moulding then, dry in the shade, repaired biscuit, sintering form, it is characterized in that containing at least in the said powder:
Zircon sand 26-30%;
Ferric oxide 3-7%;
Chromic oxide 4-7%;
Suzhou potter's clay 23-33%;
Lapis amiridis 27-41%;
Cobalt oxide 1-5%.
2,, it is characterized in that and the weight of going into clear water is the 10-13% of powder as the sintering method of the said infrared radiant material of claim 1.
3,, it is characterized in that sintering temperature is 1150-1350 ℃ as the sintering method of claim 1 or 2 said infrared radiant materials.
