Description

Downconversion frequency shift infrared radiation enhanced coating and preparation method thereof

Technical field

The present invention relates to a kind of infrared radiation coating and preparation method thereof.

Background technology

Infrared radiation coating is applied to various industrial furnaces and civil boiler heat absorption surface; Utilize coating to thermal-radiating high-absorbility and high emissivity principle; Can improve stove lining body or boiler tube wall to the absorption of furnace flame heat, improve burner hearth heat exchange condition, increase thermo-efficiency; The provide protection that simultaneously burner hearth lining body material is had good resistance to high temperature oxidation, the work-ing life of prolongation stove and boiler, minimizing maintenance workload.In addition, conduct heat, improve the temperature homogeneity of thermal field in the stove and the heating quality of heated body through strengthening radiation of burner hearth, thereby people's attention extremely.Infrared radiation coating is as a kind of energy-conservation novel material, the today in that the energy and carrying capacity of environment increase the weight of day by day, demonstrates great vitality and application prospects.

Ir radiation is a section in the electromagnetic spectrum, its wavelength region 0.760～1000 μ m, correspondent frequency scope 4 * 10 ¹⁴Hz～3 * 10 ¹¹Hz, corresponding photon energy range 1.66eV～1.26 * 10 ^-5EV.Ir radiation is called thermal radiation again, but itself does not have thermal properties, but in its range region by material absorbing, make electronics or ion in material molecule and the atom produce the heat effect that receives to compel resonance and cause.All objects all can emit infra-red radiation when temperature is higher than zero absolute temperature; When object is black matrix; Its radiation intensity depends on radiation wavelength and object temperature; And for the actual object of non-black-body, its radiation intensity not only depends on the temperature of radiation wavelength and actual object, and is also relevant with the emittance of actual object.

Heat passagely mainly contain three kinds of modes: conduction, convection current and radiation.For the heat of industrial furnace, be main mainly with radiative transfer, i.e. the heat of fuel combustion or electric pyrogenicity mainly passes to workpiece and stove lining body with the radiating mode.

When hertzian wave runs into object in radiation propagation, produce reflection and refraction at body surface.And prior art still is difficult to realize the specular reflection of stove lining surface, thus anti-its road capable it, reduce serving as a contrast the surface reflectivity, improve surperficial specific absorption.According to Kirchhoff's law, the emittance of any object all equals its specific absorption under uniform temp and the same terms.

A kind of so just functional materials of infrared radiation coating: make infrared energy in the burner hearth be converted into the heat effect of coating with high specific absorption, with high emittance heat is melted down thorax with the form emission of ir radiation again.Therefore, fail to be shifted once more and passing to workpiece through the infrared radiation coating of stove lining surface by the directly timely radiations heat energy that absorbs of workpiece.It is thus clear that the key of infrared radiation coating is to improve the specific absorption and the emittance of stove lining surface, wherein, specific absorption relates to lining surface coating to the infrared receptivity of fuel combustion, and produces thermo-effect of infrared radiation; Emittance relates to lining surface coating and improves the ability to burner hearth feedback emit infra-red radiation because of thermo-effect of infrared radiation causes temperature.

Its Heating temperature of common industrial furnace can be divided into: high temperature: 1200～1900 ℃; Middle temperature: 800～1200 ℃; Low temperature:＜800 ℃.Fundamental law according to electromagenetic wave radiation can know that the stove radiating hertzian wave of differing temps has its corresponding spectral distribution characteristic, and wave spread corresponding with it and peak emission wavelength are promptly arranged.Drawn by Wien's displacement law: high temperature (1200～1900 ℃) stove peak emission wavelength scope is 0.94～2.37 μ m; Middle temperature (800～1200 ℃) stove peak emission wavelength scope is 1.57～3.10 μ m; Low temperature (＜800 ℃) stove peak emission wavelength scope＞2.30～3.10 μ m.The industrial furnace of differing temps, although adopted different refractory lining bodies, mostly in 0.4～0.7 scope, this provides possibility for utilizing infrared radiation coating to improve emittance to its high temperature lower surface emittance.

The material that ir radiation is had high emissivity has usually: MOX, carbide, nitride, boride etc.But different infrared radiant materials, its emittance not only change with radiation wavelength, and with temperature variation, this various just infrared radiant material emittance substantial differences place.

In sum, the following factor of design considered of infrared radiation coating: 1. mate and use different infrared radiant materials, make it under corresponding temperature and wavelength, have the comprehensive emittance of metastable height according to stove working temperature and peak emission wavelength; 2. the particle size of powder body material has considerable influence to electromagnetic scattering and receptivity, and particle size is more little, and it is high more to the absorption of electromagnetic wave ability, and scattering power reduces.But too much reduce particle size to corresponding ir radiation wavelength, may have a negative impact to preventing particulate material oxidation and thermostability, and improve the material prepn cost.In addition, suitable particle size and grating design, and can improve the compactness of coating, reduce the consumption of coating; 3. its thermal expansivity of different infrared radiant materials has than big-difference, and the infrared radiation coating components do match should be taken into account lining body material coefficient of thermal expansion property, to improve the coating thermal shock resistance; 4. between the infrared radiation coating component particles, between particle and the stove lining body, at high temperature has the good binding performance, to prevent coming off of particulate coating; 5. infrared radiation coating should have good sticking power and rheological at normal temperatures, makes coating that good construction performance arranged.

To energy-saving and cost-reducing remarkable meaning, researched and developed the infrared radiation coating of multiple formulations and purposes based on the ir radiation technology both at home and abroad.As, the ET-4 infrared radiation coating of Britain CRC company, its radiation component mainly is zircon sand, silicon-dioxide, alchlor.The CRC-10A of U.S. CRC company, G-125 and SBE infrared radiation coating, its radiation component that is used for metal coating material mainly is silicon-dioxide and aluminum oxide; Be used for the refractory material furnace lining topcoating, its radiation component mainly is that zirconium white or zircon sand, silicon-dioxide, aluminum oxide are formed.The Encoat infrared radiation coating that the multinational joint operation of Britain Harbert Beven company and Europe Australia is released, its radiation component mainly adds protective agent by silit and forms.The CRC1100 and the CRC1500 infrared radiation coating of Japan CRC company, its radiation component mainly is CoO, Cr ₂O ₃, Fe ₂O ₃And MnO ₂Deng composition.The infrared radiation coating of these offshore companies is not reported its coating composition and relevant design thinking; But known application message shows; Its component has mainly adopted MOX and high emissivity materials such as resistant to elevated temperatures zirconium white, aluminum oxide and silit, and as the silicon-dioxide spectrum ir transmitting material of sticker and inhibitor.In addition, the data report, the grand first-class of wide husband in high island and high fields of Japan is used oxide compound, as: Fe ₂O ₃: 80%, MnO ₂: 15%, CoO:5%; MnO ₂: 80%, CoO:10%, CuO:10%; MnO ₂: 60%, Fe ₂O ₃: 20%, CuO:10%, CoO:10% etc. behind 1150 ℃ of reaction sinterings, have high ir spectra emittance in 2～5 mu m waveband scopes, sintering again behind the trichroite of admixture 50%, its ir spectra emittance does not subtract basically.
