Description of JM26 Insulation Brick

Excellent Thermal Insulation
Low Thermal Conductivity
High Cold Crushing Strength
High Compressive Strength
Good Thermal Shock Stability
Perfect Energy Saving

The main components of JM26 insulation brick are high-purity alumina and talc. Kerui will strictly grade filling materials according to the different needs of customers. Furthermore, these fillers are burned during the manufacturing process to create a uniform pore structure. Therefore, it has good fire resistance and thermal insulation properties. In addition, each grade of the product is uniquely designed to meet different thermal, physical and chemical needs. We usually use JM26 mullite insulation bricks for sale for thermal insulation of high-temperature industrial equipment. Moreover, it can effectively reduce the surface temperature loss of equipment and improve energy efficiency. That is to say, the application of JM26 insulation brick extends the service life of the equipment.

Attention to Detail When Using JM26 Insulation Brick

When using JM26 insulation bricks, there are some details that need to be paid attention to. By paying attention to the following details, the service life and insulation effect of JM26 insulating fire brick can be effectively improved. Moreover, it can also ensure the normal operation and safety of industrial equipment.

  • Selection of supporting materials: when using JM26 insulation bricks, supporting materials that meet the requirements should be selected. Such as binders, high temperature refractory cement, etc. to ensure the overall use effect;
  • Flat installation: we must install the insulation bricks on a flat and solid foundation. In addition, we also need to ensure that the connections between the refractory bricks are tight to avoid gaps;
  • Waterproofing: when using JM26 insulation bricks, you need to pay attention to waterproofing to avoid damage to the bricks caused by long-term exposure to moisture;
  • Avoid collisions: when transporting and installing JM26 insulation bricks, avoid collisions and falls. This can prevent brick damage from affecting the use effect;
  • Temperature control: the maximum operating temperature of insulation bricks should comply with its design requirements. This prevents the bricks from being deformed or damaged due to over-temperature use;
  • Avoid rapid temperature changes: when using JM26 insulation bricks, try to avoid rapid temperature changes to avoid causing thermal stress to damage the bricks;
  • Regular inspection: Regularly check the installation and status of the insulation bricks. If you find problems such as loose or cracked heat resistant bricks, repair them promptly.
