Description

Product Description：

Ceramic fiber board is made of ceramic fiber cotton, natural refractory raw materials and a small amount of organic binder as the main raw materials, and is processed by a fully automatic control continuous production line. Industrial kiln backing provides a strong guarantee for kiln energy saving, consumption reduction, high quality and high yield.

Product Feature :

1. Low thermal capacity, low thermal conductivity

2. High compressive strength

3. Non-brittle material, good toughness

4. Accurate size and good flatness

5. Homogeneous structure, easy to machine and install

6. Continuous production, uniform fiber distribution and stable performance

7. Excellent thermal stability and thermal shock resistance

Product Application:

1. Power industry, power boilers, steam turbines and nuclear power insulation.

2. Fire and heat insulation in the shipbuilding industry.

3. Fire and heat insulation of construction industry and fire doors.

4. Wall lining of high temperature reaction equipment and heating equipment in chemical industry.

5. Automobile, train manufacturing, fire prevention, heat insulation.

6. Furnace lining, furnace door, top cover.
