The content of ceramic fiber cotton slag ball is currently set at no more than 15%, 18%, and 25%. It seems that the index is too high and should be revised. The current electric power industry standard stipulates that the dry method shall not exceed 12% and the wet method shall not exceed 15%. Reducing the fiber diameter and increasing the fiber length can further improve the thermal insulation performance and use performance of fiber materials. For example, the ceramic fiber cotton produced by centrifugation has a longer length and can be made into 4~5 cm thick felts for pipe insulation. The increase in the use temperature is very beneficial to the expansion of the use range of fiber materials. At present, the main way to increase the use temperature is to improve the curing agent and select temperature-resistant inorganic binders.
