Advantages of Kerui Ceramic Fiber Board

Good Thermal Insulation

The low thermal conductivity helps improve the thermal insulation. When the temperature of the ceramic furnace lining up to 400℃, the thermal conductivity is less than 0.11w/m.K. Its thermal conductivity is clay bricks’ 1/8. It has great thermal insulation.

High Tenacity

Ceramic fire boards can resist dramatic temperature change and mechanical shock. It undertakes rapid increases or decreases the temperature that will not be broken. And it could resist high pressure. So refractory ceramic fire board can be used in some parts that are easy to abrasion. It could also reduce the stress transfer to again higher energy utilization efficiency.

Noise Reduction

Ceramic boards can reduce noise. The ability of sound insulation is better than other materials. It could significantly reduce noise pollution. And high temperature ceramic fiber board can be used in high-temperature situations where need to reduce the noise.

Good Chemical Stability

Ceramic fire board has excellent chemical stability. There is a lot of alumina in the board. It will present the characteristics of ceramic that will not react with chemical solutions. So it could resist chemical erosion in high-temperature environments to extend the service time.
