Abstract
A process for producing a base material for disks including forming a raw slurry material into a platy shape and drying the plate, the raw slurry material containing inorganic fibers which have a wet volume of about 300 mL/5 g or larger and which are amorphous or have a degree of crystallinity of about 50% or lower.
Claims5
A disk for use in a disk roll comprising a rotating shaft and ring-shaped disks fitted thereon by insertion, whereby the peripheral surface of the ring-shaped disks serves as a conveying surface,
- the disk consisting essentially of
- more than 30% by mass to about 70% by mass of mullite fibers comprising Al2O3 and SiO2 in a ratio that Al2O3:SiO2 is from about 60:
- about 40 to about 99:
- about 1,
- about 2% by mass to about 30% by mass of Kibushi clay,
- 2% by mass to 20% by mass of bentonite,
- more than 25% by mass to about 40% by mass of mica, and
- optionally one or more members selected from an organic binder, organic fibers and a flocculant.
