What is the JM26 insulating firebrick

Mullite brick is also called mullite lightweight brick or mullite thermal insulation brick. Mullite thermal insulation brick is a high alumina refractory material with mullite (₃Al2O₃·₂SiO₂) as the main crystal phase. Generally, the alumina content is between 40% a 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. JM26 mullite insulating firebrick is a kind of mullite brick.

Features of k26 insulating firebrick

As a refractory material with excellent performance, k23 insulating firebrick has a high melting point, high-temperature strength, low thermal expansion coefficient, excellent thermal shock resistance, etc., making it a refractory material in many industrial fields.

Three classification methods of mullite insulation bricks

• Mullite insulation bricks are divided into JM23, JM26, JM28, and JM30 according to the grade.

• Mullite insulation bricks are divided into light mullite insulation bricks and corundum mullite insulation bricks (also known as heavy mullite insulation bricks) according to 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. according to different operating temperatures, a 1550 mullite thermal insulation bricks can directly contact flames, and have high-temperature resistance and thermal conductivity. The coefficient is small, and the energy-saving effect is remarkable.

The raw material composition of mullite

Mullite insulation brick is a high-quality insulation brick made of high-quality high-alumina bauxite clinker as the main raw material, mixed with an appropriate amount of clay, ingredients, and water to make plastic mud or mud, extruded and fired at high-temperature Thermal insulation bricks.

Insulating firebrick JM26 application

• In the metallurgical industry, mullite can be used for hot blast stove bricks or kiln furniture bricks;
• In the glass industry, mullite can be used in structures such as glass containers, water feeders, and the top of glass kilns; in the field of ceramics, mullite can be used in high-temperature structural ceramics;
• In the gas industry, mullite can be used in oil gasification equipment, coke ovens, and gas generators in all gasification workshops.
• Mullite bricks can be used as the main component of the lining of furnace kilns, oumu pupuhi, and continuous casting furnaces
