Polycrystalline mullite fiber blanket
Fiber blanket is used in particular to strengthen needling process and fiber blanket, the process does not contain any bond or other ingredients, by strengthening the needling process and a corresponding increase in the fiber of the interleaving degree and blanket anti delamination capability, in does not affect the flexibility and so that it also has good tensile strength. The installation method is simple, greatly accelerate the construction speed of lining.
