摘　　要：纳米红外节能涂料是由优质的抗氧化物质经超细化处理制得的高辐射材料,将此材料涂覆于经表面处理后的格子砖表层,可提高格子砖的发射率,提高其蓄热能力。实验室试验表明,600℃时,蓄热量提高率为9.93%。1200℃时,蓄热量提高率为18.30%,岩相分析表明,涂料与格子砖呈渗态结合。工业应用表明,格子砖表层涂覆微纳米红外节能涂料可提高热风炉送风混前温度30℃,降低煤气消耗8%。The nano infrared energy conservation coating material is a strong radiation coat which made of high quality oxidation-resisting matter by uhrafine treatment. When the surface of checker brick is coated hy this material after treatment, its emissivity and regenerative capacity can be increased. Test results in laboratory show that the regenerative capacity is increased by 9.93% at 600℃ and hy 18.30% at 1200℃. Petrographical analysis shows that the coating material permeates into the interval of the choker brick, industrial application shows that the blast temperature of the hot-blast stove is increased by 30℃ and the gas consumption is decreased by 8% after the surfare layer of the checker brick is coated by the nano infrared energy conservation coating material.
