definition

Ceramic fiber board is also called aluminum silicate board. It is made from ceramic fiber adding certain proportion of 

anchoring agent and auxiliary. It is produced by 

one-time forming production line of aluminum silicate 

board. It is an ideal energysaving material for furnace, 

pipeline and thermal insulation equipment.
