The common ones are made of hard chamotte clay, which are melt down in resistance furnaces and processed by blowing or needled technology.
The high pure and high aluminium ones are made of composite materials of pure alumina and silica powder, which are melt down in resistance furnaces and processed by blowing or needled technology.
Zirconium ones are made of composite materials of high purity alumina, silica powder and zirconic sands, which are melt down in resistance furnaces and processed by blowing or needled technology.
Features of needled fiber bulk:
Needled ones have long fiber, low ball sediment and low non-fiber material content. The long fiber produced by untreated needled fiber 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 fiber 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, fiber spraying and fiber paper.
Typical Application
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 filling
Raw materials of fiber textile products
