Mullite lightweight bricks According to different use temperatures, insulation brick manufacturers can produce a variety of different types of lightweight mullite insulation bricks. Multiple grades of mullite lightweight insulation bricks are divided into JM23/JM26/JM28, and the use temperature range is from 1100℃-1790℃. The proportions of each lightweight insulation brick product are specially designed to meet different thermal and physical requirements. Mullite insulation bricks are used as hot surface refractory linings or backing insulation layers of other refractory materials and are used in ceramic kilns, roller kilns, ammonia secondary reforming furnaces, and other similar industrial thermal equipment.
Performance Characteristics of JM23/JM26/JM28 Series Thermal Insulation Lightweight Bricks
JM series mullite insulation bricks have high purity and low impurity content. It is resistant to high temperatures and can be directly exposed to flames, which is very important. Resistant to corrosion in various atmospheres, low thermal conductivity, low hot melt. And it has excellent thermal shock resistance. High dimensional accuracy and can be cut at will.
The brand of JM lightweight insulation bricks is derived from the insulation bricks of Morgan Heat Resistant Ceramics Company. The applicable temperature range is from 1100℃ to 1790℃, which can meet the lining needs of thermal insulation layers of different thermal equipment.
JM insulation bricks are the first choice of lightweight bricks for most kiln insulation layers. The physical and chemical indicators of JM23, JM26, and JM28 lightweight bricks are fixed indicators. Therefore, when purchasing, users can choose appropriate insulating bricks based on the physical and chemical indicators of lightweight bricks to build furnace linings. The physical and chemical indicators of JM23/JM26/JM28 series thermal insulation lightweight bricks include grading temperature, volume density, flexural strength, compressive strength, thermal conductivity, and chemical composition content.
JM insulation bricks adopt Morgan company standards, so they do not focus on national standards. It can be based on the actual situation to meet the actual needs of the furnace. Insulating bricks have a wide range of applications and require better masonry linings. Therefore, the requirements for the physical and chemical indicators of lightweight insulation bricks are stricter, and they must comply with the operating temperature and compressive strength of the furnace.
Application Advantages of JM Series Mullite Insulation Bricks
Lower thermal conductivity. It has a good thermal insulation effect and can make the furnace wall thickness thinner.
Low heat capacity. Due to its lightweight and low thermal conductivity, the lightweight mullite brick range accumulates very little heat. The energy-saving effect is obvious in intermittent operation kilns.
Low impurity content. It has very low iron and alkali metal refractory content and therefore has high refractoriness. The higher aluminum content allows it to maintain good performance in reducing atmospheres.
What do Jm23/Jm26/Jm28/Jm30 of Lightweight Mullite Insulation Bricks Mean?
Lightweight mullite insulation bricks are a high-quality building insulation material and are widely used for thermal insulation of furnace walls, furnace roofs, floors, and other parts of various building kilns. Among them, Jm23/Jm26/Jm28/Jm30 represent different grades of products. They respectively represent different thermal insulation properties and application ranges.
Jm23 is one of the most commonly used lightweight mullite insulation bricks. It is suitable for thermal insulation of high-temperature media and has good compressive strength and earthquake resistance.
Jm26 has excellent thermal insulation performance and is suitable for occasions with higher temperatures. Such as heating furnaces, kilns, etc.
Jm28 has better thermal insulation performance and is suitable for thermal insulation in high-temperature environments. Such as metallurgy, chemical industry, and other fields.
Jm30 has the strongest thermal insulation performance and is suitable for thermal insulation in extremely high-temperature environments. Such as steel, glass, and other industries.
Different grades of lightweight mullite insulation bricks will have different thermal insulation performance and application ranges. Users can choose corresponding products according to specific requirements to achieve the best thermal insulation effect.
