Excellent Quality Mullite Insulation Brick JM30

Product description of mullite insulation brick JM30

Mullite insulation brick JM30 is a high alumina refractory with mullite as the main crystalline phase. Generally, the content of alumina is between 65% and 75%. In addition to mullite, the lower alumina content also contains a small amount of glass phase and quartolite; Higher alumina content also contains a small amount of corundum.

Features of mullite insulation brick JM30

  1. Low thermal conductivity, with good heat insulation effect
  2. Mullite insulation brick has high thermal compressive strength
  3. Mullite insulation bricks can be processed into special shapes
  4. Mullite insulation brick has low heat melt. Due to low thermal conductivity, Mullite series light insulation brick stores little heat energy, which has obvious energy-saving effect in intermittent operation
  5. Accurate appearance, speed up the masonry speed, reduce the use of refractory mud, ensure the strength and stability of masonry, thus extending the life of the lining
  6. Low impurity content with very low iron box alkali metal oxide content, therefore, high refractoriness; The high aluminum content makes it maintain good performance in reducing atmosphere

Application of mullite insulation brick JM30

JM30 insulation bricks can be used as a primary refractory lining or backside insulation behind all other refractory layers in furnaces, ovens, furnaces, refining chambers and heating furnaces, regenerators, natural gas production plants and pipelines, prospective furnaces, stress relief furnaces, reactor chambers and similar high temperature industrial installations.
