1.Product description of insulation fire clay brick
Lightweight refractory clay insulation bricks are made of top local refractory clay materials at high temperatures according to the latest international standards, featuring uniform bulk density, high strength, low thermal conductivity and low impurities. The temperature is 1200-1400°C. These components are mixed with water to make a plastic material or slurry, extruded or poured shape slurry, dried and burned at 1250-1350°C in an oxidized atmosphere. Commonly used clay bricks have a capacity of 0.75-1.2 g/cm3. In fact, 1.0 or more lightweight refractory clay bricks insulation brick index is the most concise way to judge its performance.
