Introduction of Lightweight Clay Insulation Bricks
The Al2O3 content of clay insulation brick is about 30-46%. The higher content of Al2O3, the better refractoriness it has. With superior materials and advanced production technology, Kerui clay insulation brick has great properties. Also, this brick mainly uses clay clinker or light clinker as the main raw material. Therefore, it also has the advantage of good resistance on acid chemical corrosion. Kerui has rich manufacturing experience of clay insulating bricks for about 20 years. If you need light weight clay bricks, please get in touch with Kerui now.

How to Choose Suitable Lightweight Clay Insulation Bricks?
In the application of heat insulation, Kerui provides 3 types of lightweight clay insulation bricks with different bulk densities: 1.0 g/cm³, 0.8 g/cm³ and 0.6 g/cm³.
For lightweight clay insulation brick with bulk density at 1 g/cm³. This is the most commonly used type. Customers who are operating shaft furnace or pellet furnaces can choose this kind of brick. Kerui fireclay insulation brick has the highest refractoriness among the 3 types.
Kerui lightweight fire clay bricks for sale with bulk density at 0.8 g/cm³ are often seen in furnace walls of some calcium carbide furnaces. That is also to say, customers have lower demand for refractoriness, this brick is suitable. Besides, these clay insulation bricks can avoid loosening and dropping effectively.
While the clay insulation brick with bulk density at 0.6 g/cm³ is suitable for kilns with higher requirements on the weight of insulation brick. For example, if your kiln is high, it’s recommended to use this brick to avoid collapse and squeeze inside.
Characteristics of Kerui Lightweight Clay Insulation Bricks
In the operational context of intermittent kilns and furnaces, these bricks exhibit outstanding insulating properties. Notably lightweight, these bricks effectively reduce the overall weight of thermal equipment. Thereby, application of Kerui lightweight insulating firebrick contributes to energy savings and operational efficiency greatly.
With its impressively low thermal conductivity, Kerui clay insulation brick excels at isolating and storing heat. This capability enhances its efficiency in maintaining temperature gradients and minimizing heat loss, which is particularly advantageous for industries requiring precise thermal management.
Even when exposed to corrosive acidic conditions or other reducing atmospheres, the clay insulation brick remains steadfast in performance. Correspondingly, this ability is helpful to extend the service life of the high temperature brick as well as the brick. Kerui fire clay insulation brick is a reliable choice.
The versatility of Kerui clay insulation brick shines through in its wide array of potential uses. As long as direct flame contact is avoided, these bricks can be employed for insulation in diverse construction projects. These bricks provide effective thermal isolation.
