Ceramic fiber board

Ceramic Fiber Board is made of Alumina-Silicate fibrous wool by vacuum forming process.
The board includes 6 levels: 1050℃, 1260℃, 1350℃, 1430℃, 1600℃, and 1700℃. Ceramic fiber board can resist the scouring of airflow for its high strength, so it can be the material of internal linings. In some thermal equipment, when burned, the organic binder in the board will be smoke and smell out, this is a normal phenomenon, the smoke will soon dissipate.


Features

The precise size and smooth surface
Easy to cut and install, and convenient to construct
Low impurity content; well-proportioned density and thickness.
Excellent mechanical strength and structural strength.
Low thermal conductivity and low shrinkage.
Ability to resist the scouring of airflow.

Applications

Kiln lining of building material industry.
The lining of the nonferrous industry for insulation.
Kiln lining of the industries like petrochemistry, metallurgy, ceramic, and glass.
