At present, the content of ceramic fiber cotton residue ball is no more than 15%, 18% and 25%. It seems that the index is too high and should be revised. The current power industry standard stipulates that the dry method is not more than 12% and the wet method is not more than 15%. Reducing the fiber diameter and increasing the fiber length can further improve the thermal insulation performance and service performance of fiber materials. For example, the ceramic fiber cotton produced by centrifugation has a long length and can be made into 4 ~ 5 cm thick felt for pipeline thermal insulation. The increase of service temperature is very beneficial to expand the application range of fiber materials. At present, the main way to improve the service temperature is to improve the curing agent and select temperature resistant inorganic binder.
