Light thermal insulation castable is a kind of granular and powdery material made of refractory materials with quantitative binder. Has high fluidity, and is suitable for amorphous refractory materials formed by pouring. It has the advantages of low thermal conductivity, good thermal insulation performance, small linear shrinkage, high drying strength and good integrity. Light heat-insulating castable can significantly improve the airtightness and integrity of the chimney lining wall and the anti-erosion ability of the lining, which can save energy and protect the environment. According to different customers' requirements, the lightweight heat insulation castables are processed into lightweight castables at low temperature, medium temperature and high temperature by optimizing the combination of aggregate and binder. Aggregate has great influence on the properties of lightweight castable. Generally, the smaller the bulk density of aggregate is, the smaller the bulk density of lightweight castable is. But the strength of aggregate decreases with the bulk density decrease. Reducing the size of pores in aggregate and making pores evenly distributed in aggregate will improve the strength and reduce the thermal conductivity. In addition, there are a lot of open pores in the aggregate which is widely used at present, and some cement and water will enter the pores, which increases the cement consumption. Therefore, uniform pore distribution, small pore size and closed pores are the goals pursued by lightweight aggregate. Application: It is mainly used for thermal insulation lining of thermal equipment such as high temperature industrial kiln. High chimney, high temperature flue and air duct lining.
