摘　　要：介绍了一种加热炉表面保温修复技术中的应用,包括气凝胶隔热保温涂料应用、保温结构设计、保温涂装施工工艺及隔热效果评价。结果表明:采用自研气凝胶隔热保温涂料对加热炉表面保温失效区域进行修复,可以明显降低炉体表面温度,有效减少热量向外界的散热损耗,进而提高加热炉热效率;与原有保温涂层相比,修复用气凝胶保温涂层隔热性能及机械性能更加优异;在保温结构设计方案中,保温涂层与防护面层之间设计的界面剂粘接层可显著提高配套体系耐水、耐盐雾性能,降低保温层下腐蚀风险。In this paper,a repair technique of thermal insulation coating on heating furnace surface was introduced,including the application of aerogel thermal insulation coatings,the design of thermal insulation structure,the construction technology of thermal insulation coating and the effect evaluation of thermal insulation.Results showed that when the failure area on the furnace surface was repaired by the self-developed aerogel thermal insulation coatings,the surface temperature of furnace outer wall could be reduced significantly,and the thermal efficiency of furnace was improved effectively through reducing the heat loss.Compared to the original thermal insulation coating,the self-developed coatings showed better performance in thermal insulation and mechanical properties.In the proposed scheme of thermal insulation structure design,the adhesive layer composed of interfacial agent located between thermal insulation layer and protective surface layer could increase the water and salt spray resistance of the supporting system,and further reduce the risk of corrosion under insulation。
