Insulating refractory slurries are made from heavy and light refractory raw materials and a certain amount of binder and external additives. It is a special mud for laying insulation and refractory products. This product is suitable for lightweight insulation brick masonry of industrial kiln in metallurgy, petrochemical, ceramic, electric power, machinery and building materials. This series of insulating refractory mud is bagged finished material, which is convenient for transportation and storage. When the site is constructed, it can be unpacked and stirred with water. It has good masonry performance, easy application, no drooling, small shrinkage, high bonding strength, low thermal conductivity, good thermal insulation performance and strong integrity. It can meet the requirements of high efficiency, energy saving and longevity of modern industrial furnaces.
