Description
Technical field
The present invention relates to a kind of ceramic coating, more precisely, relate to a kind of high-emissivity ceramic paint that can improve furnace thermal efficiency, can be applicable to oil, chemical industry, metallurgy, electric power, other chemical industry and civilian stove, boiler etc.
Background technology
Ceramic coating is applied in a lot of industry; it can be used in the heat absorbent surface of various industrial furnace and civil boiler as refractory materials; utilize coating to the principle of thermal-radiating high-absorbility and high emissivity; raising High Temperature Furnaces Heating Apparatus kiln lining body or boiler tube wall are to the absorption of furnace flame heat; improve the heat exchange conditions of burner hearth; body of heater is dispelled the heat decline; add the thermo-efficiency of energy utilization; to burner hearth substrate material, there is good provide protection simultaneously, extend the work-ing life of stove and boiler, reduce maintenance workload.In addition, by strengthening Radiative heat transfer in furnace, the homogeneity of temperature field in furnace and the heating quality of heated object can also be improved.
High-emissivity ceramic paint is made up of high temperature resistant base-material, high emissivity additive and tackiness agent usually.Normally used high temperature resistant base-material has zirconium white, zirconium silicate, aluminum oxide, pure aluminium silicate, silicon-dioxide etc.High emissivity additive is most typical is transition metal oxide, such as, and chromic oxide (Cr
20
3), cobalt oxide (CoOx), ferric oxide (Fe
20
3) and nickel oxide (NiO).In some coating, high temperature resistant base-material and high emissivity additive are same material.
Following factor should be considered: under high temperature, there is metastable high emissivity during high-emissivity ceramic paint design; Suitable particle size; With the thermal expansion matching of matrix, mechanical bond, chemical binding; The hot properties of coating, erosion resistance and wear resistance; There are good sticking power and rheological under normal temperature, are easy to construction; Finally also have the cost of coating, if the cost of coating is far away higher than the energy recovery of plan, so this coating is without any economic implications.
Have developed the high-emissivity ceramic paint of multiple formulations and purposes at present both at home and abroad.But when application of paints is to higher temperature, or when carrying out work for a long time under multicomponent atmosphere, the performance of coating can be subject to great impact, coating efficiencies declines and even lost efficacy.
Summary of the invention
The object of this invention is to provide one in temperature more than 1400 DEG C, to work under multicomponent atmosphere for a long time, be easy to construct (spray gun can be used to spray), economical and practical high-emissivity ceramic paint.This coating can be applicable to oil, chemical industry, metallurgy, electric power, other chemical industry and civilian stove, boiler etc., and can improve the thermo-efficiency of stove.
Following technical scheme is adopted: a kind of high-emissivity ceramic paint, is characterized in that: comprise base-material, additive, tackiness agent, softening agent and solvent for realizing object of the present invention, wherein:
Described base-material and additive be selected from gahnite powder, manganese-aluminium spinelle powder, boron nitride, norbide, ferric oxide, five kinds of yttrium oxide or all;
Described tackiness agent is made up of liquid phosphoric acid aluminum dihydrogen, liquid phosphoric acid dihydro magnesium.
Preferably, described softening agent is selected from yellow starch gum and/or carboxymethyl cellulose.
Preferably, described solvent be selected from silicon sol, water one or both.
Preferably, the weight percent of described base-material and additive is 5%-78%, and the weight percent of tackiness agent is 5%-30%, and the weight percent of softening agent is 0.5%-3%, and surplus is solvent.
Preferably, described high emissivity additive is nano material.
Coating of the present invention contains gahnite powder, makes coating not only improve the emittance of coating, and coating can use for a long time in acid-basicity atmosphere.Additive of the present invention is nano material, and specific surface area is large, and the ability of absorb photons is high, and scattering power is little, further increases the emittance of coating.Coating of the present invention is made by Powdered base-material and additive, softening agent, liquid adhesive and solvent, when low temperature brushing or spray to stove matrix on or on metallic conduit, by using after 100 DEG C of dryings, construct simple and convenient.Coating of the present invention can use at the temperature more than 1400 DEG C, and maximum operation (service) temperature can reach nearly 2000 DEG C.High-emissivity ceramic paint of the present invention is applicable to various matrix, and to the strong adhesion of matrix, be applicable to soda acid multicomponent atmosphere, long-term durability is good, heat shock resistance ability to bear is strong, improves energy utilization thermo-efficiency, reduces substrate temperature, wear-resisting and good corrosion resistance is little to environmental influence, easy to use.
