Hengrui thermal insulation board for industrial furnace is made by using Hengrui ceramic fiber bulk and a little binding agent through vacuum forming. Hengrui thermal insulation board can maintain its mechanical strength after high-temperature heating, and the board includes 6 levels: 1050℃, 1260℃, 1350℃, 1430℃, 1600℃, and 1700℃. Hengrui thermal insulation board can resist the scouring of airflow for its high strength, so it can be the material of internal linings.
The usability of thermal insulation board is really good under the condition of high moisture. Hengrui ceramic fiber board has excellent hyd-rophobicity after processing by specific techniques.
Hengrui thermal insulation board is made by using Hengrui ceramic fiber bulk and inorganic binding agent through vacuum forming. When using the board under the circumstance of high temperature, the pollution gas will not be generated.
