High-aluminum poly-light thermal insulation bricks are also called high-aluminum poly-light ball bricks, which are produced by poly-light loss-on-ignition method with super-grade blast furnace materials as the main raw material, supplemented by appropriate additives. The product has the advantages of high strength, good thermal stability, small change of reburned fiber, and low thermal conductivity. Features are as follows:
1. High temperature strength;
2. Good thermal insulation performance;
3. Resistance to corrosion in various atmospheres;
4. Features such as remarkable energy-saving effect;
5. Excellent thermal shock stability.
The high-alumina poly-light brick has reached various technical indicators of similar products, and it is a new material that must be selected in the design of industrial kilns. It is widely used in kiln lining (not corroded by solution) and insulation layer in metallurgy, machinery, ceramics and chemical industries. It is an ideal energy-saving product.
