Luyang ceramic fiber board is a type of boards made of refractory fiber materials with standard thickness. It is made of refractory fiber pulp and bond with low content of organic bond. With different refractory fiber, abio-bond and organic bond and mixing according to different scales, we can manufacture various fiber boards which can be applicable for different temperatures. In some thermal equipments, there will be smoke generated when the bond in fiber boards is burnt and the smoke will be disperses soon.
