Suitable for rapid repair of industrial furnaces combined with silica mullite potting

The present invention discloses a silica sol suitable for rapid repair of industrial furnaces binding potting mullite, refractory technical field belongs. Potting material from the following components in weight percent composition: mullite particulate material 50 ~ 60%; Mullite 10% to 20%; corundum powder, 5 ~ 10%; α- activated alumina powder 4 to 15%; oxide magnesium 0.6 to 1.0%; 0.7% dextrin, 0.5 ~; 10 ~ 16% silica sol; dispersible alumina 1 ~ 2%. Sol separate packing; remaining ingredients were weighed into a dry form by uniformly mixing ratio of aggregate by mechanical stirring; at the construction site, and individually packaged dry silica uniformly shaped by the ratio of aggregate weighed, mixed and stirred uniformly after construction pumped. The present invention perfusion cuisine of excellent performance, good construction performance, the use of pumping construction, saving manpower and resources to meet the need for rapid repair of industrial furnaces, is an adaptation of a strong high-quality refractory maintenance.
