Light Weight Thermal Insulation Brick is a revolutionary brick type developed using advanced manufacturing processes and high-quality alumina as additive to meet the different temperatures. This brick is provided with unmatched features of low thermal conductivity, high strength and excellent heat preservation properties. In addition to this, it shows minimum linear change on reheating. It is available in different specifications to serve the needs of metallurgy furnace, casting furnace, pottery kiln, etc. It is characterized by the occurrence of huge amount of porosity.
Production of Light Weight Thermal Insulation Brick:It is developed using premium raw-materials such as vermiculite, diatomite, ash, hollow sphere corundum, etc. These raw materials are taken in the right quantities and then mixed with water to pour into the mold. After that, the material is dried and put in the fire into a furnace to develop a ceramic bond. This is made employing the process of thermal decomposition that enables the production of pores in the insulating firebricks. Decomposition materials having minimum ash content are needed for preventing the negative impacts on the hot properties.
