What is JM26 insulating fire brick

Mullite brick is also called mullite lightweight brick or mullite thermal insulation brick. Mullite thermal insulation brick – It is a fireproof material with high alumina content, the main crystalline phase of which is mullite (3Al2O3 2SiO2). Usually, Alumina content ranges from 40% to 75%. In addition to mullite, the mineral composition contains a small amount of glass phase and cristobalite with a low alumina content and a small amount of corundum with a high alumina content. Mullite insulating fire brick JM26 – This is a type of mullite brick.

Features of k26 insulating fire brick

Being a fire-resistant material with excellent performance characteristics, K23 insulating fire brick has a high melting point, high temperature strength, low coefficient of thermal expansion, excellent resistance to thermal shock, etc., making it a fire-resistant material in many industrial applications.

Three Classification Methods for Mullite Insulation Bricks

• Mullite insulation bricks are divided into JM23, JM26, JM28 and JM30 depending on brand.

• Mullite insulation bricks are divided into light mullite insulation bricks and corundum mullite insulation bricks (also known as heavy mullite insulating bricks) depending on their density.
• Mullite thermal insulation bricks are divided into 1350 mullite thermal insulation bricks, 1450 mullite thermal insulation bricks, 1550 mullite thermal insulation bricks, etc.. depending on different operating temperatures, a 1550 mullite thermal insulation bricks can directly contact with the flame and have high heat resistance and thermal conductivity. The coefficient is small, and the energy saving effect is remarkable.

Raw material composition of mullite

Mullite Insulation Brick – This is a high quality insulating brick, Made from high quality high alumina bauxite clinker as main raw material, mixed with appropriate amount of clay, ingredients and water to obtain a plastic solution, extruded and high temperature fired insulating bricks.
