Ceramic fiber board is manufactured and designed for the thermal applications requesting high demands on rigidity, the thermal insulation properties and abrasion resistance of ceramic fiber boards have been further improved due to the higher density. Ceramic fiber board is a vacuum formed product that resists higher gas velocities than ceramic fiber blanket. Refractory ceramic fiber board is ideal for furnace, boiler duct and stack lining thanks to its thermal conductivity and low heat storage, which makes the shorter cycle times and quicker access for maintenance in the industrial furnaces possible.
Ceramic fiber insulation board is a kind of aluminium silicate fire-resisting board, which is manufactured through vacuum forming with quality aluminum silicate wool as the raw material after removing slag and impurity by washing, adding high temperature resistance binder, forcing, mould forming, dewatering and solidifying elaborate processing.
According to the working temperature and chemical components of ceramic fiber board, whcih can be divided into four types.
