Description
Technical field
The present invention relates to a kind of ceramic kiln heat radiation coating, more precisely, relate to a kind of high emissivity coating that can improve furnace thermal efficiency, can be applicable to roller kiln, tunnel furnace, the shuttle kiln of ceramic industry.
Background technology
Ceramic kiln is applied with heat radiation coating in a lot of industries; it can be used as refractory materials and uses the heat absorption surface at various industrial furnaces; utilize the principle of coating to thermal-radiating high-absorbility and high emissivity; improve the absorption of High Temperature Furnaces Heating Apparatus kiln lining body to furnace flame heat; improve the heat exchange condition of burner hearth, body of heater heat radiation is declined, increased the thermo-efficiency of energy utilization; burner hearth substrate material is had to good provide protection simultaneously, extend stove work-ing life, reduce maintenance workload.In addition,, by strengthening Radiative heat transfer in furnace, can also improve the homogeneity of temperature field in furnace and the heating quality of heated object.
Ceramic kiln is comprised of high temperature resistant base-material, high emissivity additive and tackiness agent conventionally with heat radiation coating.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, for example, and chromic oxide (Cr
2o
3), cobalt oxide (CoOx), ferric oxide (Fe
2o
3) and nickel oxide (NiO).In some coating, high temperature resistant base-material and high emissivity additive are same material.
When designing with heat radiation coating, ceramic kiln should consider following factor: under high temperature, there is metastable high emissivity; Suitable particle size; With the thermal expansion matching of matrix, mechanical bond, Chemical bond; The hot properties of coating, erosion resistance and wear resistance; Under normal temperature, there are good sticking power and rheological, are easy to construction; The cost that finally also has coating, if the cost of coating far away higher than the energy recovery of plan, so this coating is without any economic implications.
Researched and developed at present the ceramic kiln heat radiation coating of multiple formulations and purposes both at home and abroad.Yet in application of paints during to higher temperature, or while carrying out work for a long time under multicomponent atmosphere, the performance of coating can be subject to great impact, coating decrease in efficiency even lost efficacy.
Summary of the invention
The object of this invention is to provide a kind of can work for a long time in temperature over 1400 ℃ under multicomponent atmosphere, be easy to construction (can use spray gun to spray), economical and practical ceramic kiln heat radiation coating.This coating can be applicable to oil, chemical industry, metallurgical furnace kiln, and can improve the thermo-efficiency of stove.
For realizing object of the present invention, adopt following technical scheme: a kind of ceramic kiln heat radiation coating, is characterized in that: comprise base-material, additive, tackiness agent, softening agent and solvent, wherein:
