In the application of high-temperature furnaces in modern industry, heat-insulating refractories play a vital role. They can not only effectively reduce the heat loss of the furnace body and improve the energy utilization efficiency, but also maintain the stability and durability of the structure in extremely high temperature environment. JM insulating brick, as a high-profile thermal insulation and refractory product, has become an ideal choice for many industrial users with its excellent performance and wide application range.

I. Product Overview

JM insulating brick is a kind of lightweight thermal insulation refractory brick, also known as lightweight mullite brick, mullite insulating brick, corundum-mullite brick or high-alumina insulating brick. It belongs to a lightweight heat-insulating refractory material, which has the characteristics of low thermal conductivity and high refractory temperature, and is widely used in various high-temperature furnaces. This kind of brick has excellent heat insulation performance, which can effectively block heat transfer and reduce heat loss in high temperature environment, thus achieving remarkable energy-saving effect.

II. Product characteristics

JM insulating brick has many remarkable characteristics, which make it stand out among many heat insulation and refractory materials. First of all, its thermal conductivity is extremely low, which means that the transfer speed of heat in the brick body is very slow, which can effectively prevent the loss of heat and keep the temperature in the furnace stable. Secondly, it has high strength and good corrosion resistance, can maintain the structural integrity for a long time in harsh high temperature environment, and is not easy to be eroded or damaged by chemicals. In addition, the heat capacity of JM insulating brick is low, which means that it absorbs and releases less heat during heating and cooling, and can quickly respond to temperature changes and improve the operation efficiency of the furnace. It has a low shrinkage rate after high-temperature roasting, can maintain a stable size and shape, and reduces the risk of structural deformation and damage caused by thermal expansion and cold contraction. At the same time, it also has good high-temperature thermal shock resistance, can keep the structure stable under the condition of rapid temperature change, and is not easy to crack or peel off.

III. Technical data

JM insulating brick has a variety of models to choose from to meet the needs of different users. For example, JM-23, JM-26, JM-28, JM-30 and JM-32 are different in density, compressive strength, flexural strength, permanent linear change rate and thermal conductivity. Taking JM-23 as an example, its bulk density is 0.8 g/cm³, its compressive strength is 1.3 MPa, its flexural strength is 0.9 MPa, and its permanent linear change rate at 1350℃×4 hours is less than 0.5%. The bulk density of JM-32 is 1.25 g/cm³, the compressive strength and flexural strength are 16 MPa and 2.1 MPa respectively, and the permanent linear change rate at 1730℃×24 hours is 0.9%. These data show that with the upgrade of the model, the performance of JM insulating brick is gradually improved, and it can adapt to higher temperature and more harsh conditions.
