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 energy-saving material for

furnace, pipeline and thermal insulation equipment.
