The performance advantages of JM insulating brick are mainly reflected in the following aspects:

I. Low thermal conductivity

JM insulating brick has a very low thermal conductivity, which can effectively reduce heat transfer, and has a remarkable thermal insulation effect. For example, the thermal conductivity of JM-26 is only 0.21 ~ 0.32 W/(m k) at 350℃, which makes it possible to significantly reduce heat loss in high temperature environment.

II. High fire resistance

Different types of JM insulating brick have different refractory temperatures, among which the refractory temperature of JM-23 can reach 1250℃, while that of JM-30 can reach 1550℃, which can meet the needs of various high-temperature industrial furnaces.

III. High strength and stability

JM insulating brick has high compressive strength and flexural strength. For example, the compressive strength of JM-30 at room temperature can reach 3.5 MPa. In addition, its hot compressive strength is high, which can ensure the strength and stability of masonry and prolong its service life.

IV. Good thermal shock resistance

JM insulating brick has excellent thermal shock resistance in high temperature environment, which can keep the structure stable under the condition of rapid temperature change and is not easy to crack or peel off.

V. Low impurity content

This series of insulating brick has low impurity content and extremely low iron and alkali metal oxide content, so it has high fire resistance and good chemical stability.

VI. High dimensional accuracy

JM insulating brick is accurate in appearance and size, which can speed up masonry and reduce the use of refractory mud, thus improving construction efficiency and reducing maintenance costs.

VII. Significant energy-saving effect

Due to its low thermal conductivity and low thermal capacity, JM insulating brick can significantly reduce heat accumulation during intermittent operation, thus reducing energy consumption and achieving energy-saving effect.

VIII. Customizability

JM insulating brick can customize products with different shapes, sizes and properties according to customers' needs to meet specific industrial furnace design requirements.

IX. Direct contact with flame

Some models (such as JM-30) can be in direct contact with flame, which has high temperature resistance, corrosion resistance and good thermal shock resistance, and is suitable for lining in high temperature area.

These performance advantages make JM insulating brick an ideal heat insulation material for high-temperature industrial furnaces and equipment, which is widely used in steel, chemical, ceramics, glass and other industries.
