The slag ball content of ceramic fiber cotton has a significant impact on the insulation effect. Slag balls refer to short fibers and granular fragments in fiber cotton, which can reduce the insulation performance of fiber cotton. The specific impacts are as follows:
Increase in thermal conductivity: The presence of slag balls will increase the thermal conductivity of fiber cotton, making it easier for heat to be transmitted, thereby reducing the insulation effect.
Density increase: The presence of slag balls will increase the density of fiber cotton, leading to a decrease in its porosity, which in turn affects its insulation performance.
Reduced heat capacity: Slag balls have a lower heat capacity compared to fiber cotton, so the presence of slag balls will reduce the total heat capacity of fiber cotton, weakening its ability to absorb and release heat.
Reduced fire resistance: The slag ball may contain a large amount of organic matter, which is prone to combustion at high temperatures, leading to a decrease in the fire resistance of fiber cotton.

Therefore, in order to improve the insulation effect of ceramic fiber cotton, it is necessary to minimize the content of slag balls as much as possible. This can be achieved by optimizing production processes, screening fiber cotton raw materials, and other methods.
