JM26 단열 내화 벽돌이란 무엇입니까?

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) 주요 결정상으로. 일반적으로, 알루미나 함량은 40% 그리고 75%. 멀라이트 외에도, 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, 고온 강도, low thermal expansion coefficient, 우수한 내열충격성, 등., 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, 등. according to different operating temperatures, 그리고 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

뮬리트 단열 벽돌은 주요 원료로 고품질 고품질 고급 알루미나 보크 사이트 클링커로 만든 고품질 단열 벽돌입니다., 적절한 양의 점토와 혼합, 재료, 플라스틱 진흙이나 진흙을 만드는 물, 고온 열 단열 벽돌에서 압출 및 발사.

Insulating firebrick JM26 application

• 금속 산업에서는, mullite can be used for hot blast stove bricks or kiln furniture bricks;
• 유리산업에서는, 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, 코크스 오븐, and gas generators in all gasification workshops.
• Mullite bricks can be used as the main component of the lining of furnace kilns, 용광로, and continuous casting furnaces
