Ceramic fiber board is a kind of refractory fiber material board which has the standard thickness made by refractory fiber thick liquid and binderamong it the content of organic binder is very low. The ceramic fiber board is heat insulation products that possess the firm and self-supported strength quality. It uses different refractory fiberorganic and inorganic binder to mix according to different proportion to form different kinds of ceramic fiber board which have different work temperature. In some heating industrythe binder content of fiber board would appear to smoke under about 200~300℃ burningbut the smog would disappear soon.
