Characteristics of ceramic fiber wool 2

Last issue we mainly introduced density of ceramic fiber wool. This issue we will introduce diameter of ceramic fiber wool.

Diameter of ceramic fiber wool.

Diameter of blown ceramic fiber wool is 2.5～3.5μm. Diameter of spun ceramic fiber wool is 3～5μm、。 Most of the ceramic fiber wool diameter is in the range of 1 ~ 8 μm. The diameter of the ceramic fiber wool directly affects the strength and thermal conductivity of the ceramic fiber product. When the fiber diameter is relatively large, the ceramic fiber wool product feels hard, but as the strength of ceramic fiber wool products is big the thermal conductivity is also high. In ceramic fiber wool products, the thermal conductivity and strength of the fiber are basically inversely related. Alumina polycrystalline refractory fibers generally have an average diameter of 3 μm, and diameter of alumina polystalline refractory fibers also ranges from 1 to 8 μm.

This issue we mainly introduced diameter of ceramic fiber wool. Hope this can bring help to furnace builders. Next issue we will continue to introduce length of ceramic fiber wool.
