Do you know how the slay ball content influences quality of ceramic fiber paper

The slay ball density is 10 times more than ceramic fiber paper, if the content is too high, it will change the original arrangement structure of the fiber.Ceramic fiber paper’s refractory fiber board density range is 200±20kg/m3. Slay ball’s density range is 2800-3200kg/m3, is 10 times more than ceramic fiber paper. So the content of slay ball directly influences the quality of ceramic fiber paper.The high insulating castable content means lots of crystal grain in ceramic fiber paper, making the flatness and evenness worse. From the surface, some small raised can be seen. The internal fiber bulk’s structure of ceramic fiber paper with good evenness is tight and closed, so the thermal insulation is better. refractory material The internal fiber bulk’s structure of ceramic fiber paper with high slay content becomes worse , holes becomes larger, so making the alumina brick closure property worse, convection heat transfer increases, total heat transfer coefficient increases. All of the above lead to the worse of thermal insulation.The slay ball change the change the original arrangement structure of the fiber, widen the space of fibers, heavily lowering the strength of ceramic fiber paper, once the strength becomes lower, it will leading to the abradability and electrical insulation of ceramic fiber paper worse,refractories reducing the heat insulating ability and utilization rate of ceramic fiber paper.So, we can see it that the amount of slay-removal steps directly influences the slay ball content, then influences the quality of ceramic fiber paper.Changxing ceramic fiber paper is produced by 9 slay-removal steps, the slay ball content is lower than similar products, so the abradability and electrical insulation of ceramic fiber paper is better.
