Quality Production of Kerui JM26 Insulation Brick

Kerui JM26 mullite bricks are made from high-quality alumina clinker, mixed with clay, additives, and water. The mixture is formed into a plastic mold, then pressed and fired at high temperatures to create high-quality thermal insulation bricks.

The fired Kerui bricks undergo a series of quality inspections, including appearance, dimensions, refractoriness, physical properties, and chemical composition analysis. We can also provide corresponding report certificates based on customer requirements.

Note: When constructing with JM26, refractory mortar of the same material as the brick must be used. Kerui Refractory will provide other supporting products based on the insulation fire bricks selected by the customer.

Advantages of Kerui JM26 Insulating Fire Bricks

• Low Thermal Conductivity: Excellent thermal insulation, which helps reduce the thickness of the furnace walls.
• High Refractoriness: Low impurity content, with a refractoriness of up to 1430°C.
• Strong Corrosion Resistance: Good chemical stability in acidic and alkaline environments for extending service life.
• Good Thermal Shock Resistance: High alumina content ensures stable performance even in reducing atmospheres.
• High Abrasion Resistance: Maintains good wear resistance under high-speed material abrasion.
• High-Temperature Compressive Strength: Improves the strength and stability of masonry.
• Easy to Process: Can be custom-shaped to meet specific needs and reducing the number of bricks and joints.
• Factory Price: Kerui, as the source factory, offers factory price.

JM26 Insulation Brick VS Other JM Series

Grade	Jm23	Jm26	Jm28	Jm30	Results
Al2O3	42%以上	54%	64%	72%	The higher the grade, the higher the alumina content.
Refractory Temperature	1350℃	1430℃	1540℃	1650℃	As the alumina content increases, the refractory temperature also increases.
Bulk Density	0.55-1.0g/cm3	0.7-1.0g/cm3	0.8-1.0g/cm3	1.0-1.1g/cm3;	/
Room Temperature Compressive Strength	≥1.2Mpa	≥2Mpa	≥2.3Mpa	≥3Mpa	The higher the room temperature compressive strength, the greater the brick’s load-bearing capacity and service life.

Note: In addition to the common differences mentioned above, they also differ in thermal conductivity, reheat linear change rate, and other properties. These indicators reflect the material’s thermal conductivity and stability. When making a selection, we can choose based on detailed physical and chemical properties.
