Production Technology of ceramic fiber bulk

 

 

The common ones are made of hard chamotte clay, which are meltdown in resistance furnaces and processed by blowing or swinging technology.

The high purity and high aluminum ones are made of composite materials of pure alumina and silica powder, which are meltdown in resistance furnaces and processed by blowing or swinging technology.

Zirconium ones are made of composite materials of high purity alumina, silica powder and zircon sands, which are meltdown in resistance furnaces and processed by blowing or swinging technology.

Features of needled fiber bulk:

Needled ones have long fibre, low ball sediment and low non-fibre material content. The long fiber produced by untreated swinging fibre forming serves as the filling material of wall linings of heaters such as high-temperature furnace as well as the raw materials of textiles due to its good spinnability.

Features of blown fiber bulk:

The untreated fibre produced by blown fiber forming technology with low ball sediment and no lubricants serves as the filling material of high-temperature furnace and the excellent raw materials of vacuum molding products, fibre spraying and fibre paper.

Typical Application of ceramic fiber bulk

 Raw materials of fiber Paper and vacuum forming products;

 Raw materials of fiber coating materials;

 Raw materials of fiber castable and coatings;

 High-temperature furnace heating equipment wall lining fillings

 Raw materials of fiber textile products
