Purchase high-temperature insulation must see these points

Please treat the ceramic fiber material slag ball rationally
Ceramic fiber material slag ball. At present, the most widely used ceramic fiber materials are ceramic fiber cotton, ceramic fiber blanket, ceramic fiber module, ceramic fiber paper, board, cloth, belt, rope and other products. The user who uses ceramic fiber material products for the first time responds that there are some hard and fine sand granular substances at the bottom of the ceramic fiber material packaging bag or packing box, which should fall out from the ceramic fiber products. Will it affect the fire insulation performance of ceramic fiber material? Yes! These little sandy granular substances are slag balls. The slag ball in ceramic fiber products is a spherical substance produced in the production process of ceramic fiber cotton, with a diameter between 0 and 1mm, and more than 90% of the slag ball has a diameter below 0.212mm.
Effect of ceramic fiber slag ball on thermal insulation performance The national standard stipulates that the content of ceramic fiber blanket slag ball s25% of the temperature grade below 1000℃, the content of ceramic fiber blanket slag ball of the temperature grade below 1450℃ is 20%, and the content of ceramic fiber blanket slag ball of the temperature level below 1700℃ is 5%. With the current ceramic fiber production process ceramic fiber is inevitable existence, as long as the slag ball content is not exceeded, the thermal conductivity of ceramic fiber products in the industrial furnace lining insulation layer has been taken into account the impact of the slag ball, so there is no need to worry about the impact of the slag ball falling on the heat insulation performance. On the contrary, theoretically speaking, the drop of the slag ball will have an effect on the thermal insulation performance. Because the bulk weight of the slag ball is 2800~3200kg/m”, the content of the slag ball in the fiber products is too much, which will reduce the comprehensive energy saving performance of ceramic fiber products such as ceramic fiber blankets and ceramic fiber modules.
