Background technique
Zirconium oxide (ZrO2) fiber is a kind of lightweight polycrystalline fibre material that temperature-resistance thermal-insulation is had excellent performance, long-term use temperature
Up to 2200 DEG C, maximum operation (service) temperature is thermally conductive in all metal-oxide fiber refractory materials up to 2300 DEG C in short-term
Coefficient is minimum, and heat-proof quality is best, and has stable high-temperature performance, is non-volatile, is pollution-free, therefore ZrO2Fiber and its products are (such as
Fiberboard, fiber cloth, fibrofelt etc.) it is had broad application prospects in industries such as aerospace, metallurgy, petrochemical industries.ZrO2
Fiber is mainly used for the reinforcement etc. of superhigh temperature thermal insulation layer, ceramic matric composite in space shuttle；ZrO2Fiberboard is mainly made
For high-temperature electric resistance furnace burner hearth materials'use, such as it is used for crystal growing furnace, super high sintering temperature furnace.
Porous class heat-barrier material, generally refers to be formed or be sintered by mesoporous aeroge or microporous oxide powder and forms
Heat-barrier material such as SiO2Aeroge, Alumina Foam Ceramics etc..Nanoporous heat-barrier material is to be less than gas using the aperture of material
The characteristics of body molecule mean free path, it is suppressed that the mutual collision between gas molecule, to reduce gas thermal conductivity.In addition,
The unique superfine nano particle connection structure of aeroge reduces contact heat conductien to reducing solid-state thermal conductivity, red by adding
Outer opacifier can further decrease radiant heat conductanc.Therefore, the major advantage of porous heat insulation material is that thermal conductivity is smaller, matter
Amount is a kind of high temperature insulating material of comparative maturity compared with light, craftsmanship is preferable.
The porous heat insulation material of relatively early stage is mainly by micropore SiO2Powder is pressed after adding infrared light screening agent and reinforcing fiber
It makes, typical product has the tandem product of Belgian Microtherm company, can be processed into various shape, such material
Material can achieve 1000 DEG C using temperature, density 0.32g/cm3, due to infrared light screening agent (TiO2Powder) additional amount it is larger, institute
It is very low with high-temperature heat conductivity.But such material is SiO due to its matrix2, it can not be used above at 1000 DEG C, while the material
Compression strength is low.Currently, porous heat insulation material research is mainly aerogel heat-barrier material and froth inorganic stock.Aeroge
Heat-barrier material can be divided into SiO according to compositional classification again2、Al2O3、SiO2-Al2O3、ZrO2With Si-C-O etc., wherein about SiO2Gas
The most study of gel heat-insulation material, has been realized in industrialization at present.But SiO2The long-term use temperature highest of aeroge
It is 650 DEG C, in short-term using up to 800 DEG C.It common are silicon carbide, silica, aluminium oxide in inorganic foamed ceramic material
Foamed ceramics etc..The common advantage of these foamed ceramicses is use intensity and temperature all with higher.According to microcosmic reason of conducting heat
By the heat transfer of porous material is broadly divided into solid phase heat transfer, radiant heat transfer, gas heat-transfer and convective heat transfer.Though this kind of foamed ceramics
The right porosity is high, but stomata average diameter is 100~200 μm, is much larger than air mean free path 70nm, therefore high-temperature heat conductivity
It is higher.At present the zirconium oxide fiber board density that has prepared all >=1.0g/cm3, use zirconium colloidal sol as binder more, intensity is low,
And picking is serious.And influence of the high-temperature infrared to its thermal conductivity is not all considered.
