High Temperature Ceramic Fiber Board

High temperature ceramic fiber board has a hard texture, excellent toughness and strength, so it has excellent resistance to wind erosion. Moreover, it does not expand when heated, is light in weight and easy to construct. So it can be sheared and bent at will. It is an ideal energy-saving material for kilns, pipes and other insulation equipment.

Characteristics of High Temperature Ceramic Fiber Board

High temperature ceramic insulation board has several key characteristics that make them suitable for high-temperature insulation applications. Here are the main characteristics of high temp fiber boards.

High Temperature Resistance

The High temperature ceramic fiber boards are designed to withstand extremely high temperatures, typically up to 1600℃ (2912℉) or even higher. They retain their structural integrity and insulation properties even at elevated temperatures. That is to say, it makes them ideal for use in furnaces, kilns and other high-temperature equipment.

Excellent Thermal Insulation

Ceramic fiber boards have low thermal conductivity, which means they are effective in minimizing heat transfer. They provide efficient insulation, helping to reduce heat loss and improve energy efficiency in high-temperature applications.

Lightweight and Low Density

High temp ceramic fiber board is lightweight and have a low density, which makes them easier to handle, transport and install. Its lightweight nature also reduces the overall weight of the insulation system, making them suitable for applications where weight is a concern.

Low Heat Storage

Like ceramic fiber insulation blankets, ceramic fiber boards also have low heat storage capacity, meaning they have a low ability to absorb and retain heat. This characteristic allows for rapid heating and cooling cycles, making them suitable for applications that require quick temperature changes or thermal cycling.

Good Mechanical Strength and Stability

Despite their lightweight nature, high temperature ceramic fiber boards possess good mechanical strength and dimensional stability. They can withstand thermal shock, vibration and mechanical stress associated with high-temperature environments without significant deformation or damage.

Chemical Resistance

The fine High temperature ceramic fiber boards exhibit good resistance to most chemicals, acids and alkalis. This resistance ensures their durability and performance in environments where exposure to corrosive substances is a concern.

Manufacturing Process of High Temperature Ceramic Fiber Board

Raw Materials

Ceramic fibers are extruded into the finest filaments through precise spinning. Then, these fibres are organised into a carefully structured mat or blanket using controlled deposition techniques.

Forming Method

Air-laid formation randomly distributes the fibres in a loose web upon a conveyance. At the same time, wet-laid deposition suspends them within a liquid medium prior to deposition upon a screen. Finally, vacuum formation draws the fibres directly upon a mould to acquire precise dimensions. Similarly, ceramic fiber modules are formed using the same method.

Increase Strength

Subsequently, an adhesive is applied to give it cohesion without compromising its integrity. Organic materials first hold the structure as it develops strength, later yielding to inorganic binders which fortify resilience against intensified temperatures.

Cut and Shape

Then drying removes contaminants through regulated elimination of moisture and solvents, preserving the fibrous infrastructure. Finally, the dried ceramic fiber boards are cut and shaped using precision tools and mold machines. Kerui will configure different shapes according to customer needs and specifications.
