氧化铝纤维毯

Alumina fiber blanket, firstly appeared in 1950s, and be industrialised produced at the begining of 1970s. According to different fiber length, it is classified to catagories---continuous long fiber and short fiber. Alumina fiber blanket belongs to short fiber product, and alumina fiber cloth belongs to long fiber product.

Alumina fiber is manufactured by"Sol-Gel"colloidal method, to be microcrystalline mullite phase high temperature refractory fiber through high-temperature calcination.

Alumina fiber blanket is manufactured from Alumina fiber by doubled needled, doesn’t contain any additives or other ingredients.
