Abstract

A base material for a disk roll containing a layered silicate, in which the layered silicate is constituted to contain two or more kinds of minerals having an interlayer distance exceeding 10 angstroms. A base material for a disk roll is excellent in the compressive strength and wear resistance thereby.

First claim

The invention claimed is:

1. A base material for a disk roll comprising:
a layered silicate,
wherein the layered silicate contains two or more kinds of minerals having an interlayer distance exceeding 10 angstroms,
the two or more kinds of minerals having an interlayer distance exceeding 10 angstroms include at least a vermiculite and a smectite, and
a content ratio relative to a mass of the base material for a disk roll is 10 to 40 mass % for the vermiculite, and is 2 to 20 mass % for the smectite.

2. The base material for a disk roll according to claim 1 , wherein the two or more kinds of minerals having the interlayer distance exceeding 10 angstroms have the interlayer distance equal to or shorter than 100 angstroms.

3. The base material for a disk roll according to claim 1 , wherein a mass ratio of the mineral having the interlayer distance exceeding 10 angstroms to a mass of the base material for a disk roll is 12 to 60 mass %.

4. The base material for a disk roll according to claim 2 , wherein a mass ratio of the mineral having the interlayer distance exceeding 10 angstroms to a mass of the base material for a disk roll is 12 to 60 mass %.

5. The base material for a disk roll according to claim 1 , wherein the base material for a disk roll includes an inorganic fiber and clay,
wherein a content ratio relative to a mass of the base material for a disk roll is 20 to 55 mass % for the inorganic fiber, and is 5 to 50 mass % for the clay.

6. A disk roll comprising:
a cylindrical disk part; and
a shaft part to which the disk part is fitted by insertion,
wherein the disk part contains the base material for a disk roll according to claim 1 ,
wherein the disk part contacts with molten glass and is used to transport glass.

7. A method of producing glass, comprising: transporting a molten glass with the disk roll according to claim 6 .

8. A production method of a disk roll provided with a cylindrical disk part containing a base material for a disk roll and a shaft part to which the disk part is fitted by insertion comprising:
fitting the base material for a disk roll according to claim 1 to a shaft part by insertion.

9. A production method of a base material for a disk roll comprising:
preparing a slurry containing a layered silicate; and
producing a base material for a disk roll by molding the slurry,
wherein as the slurry, a slurry containing two or more kinds of layered silicates having an interlayer distance exceeding 10 angstroms is prepared, and this is molded to produce a base material for a disk roll, and
thereby producing the base material for a disk roll includes a vermiculite and a smectite as the mineral having an interlayer distance exceeding 10 angstroms,
wherein a content ratio relative to a mass of the base material for a disk roll is 10 to 40 mass % for the vermiculite, and is 2 to 20 mass % for the smectite.

10. The base material for a disk roll according to claim 1 ,
wherein the layered silicate contains three or more kinds of minerals having an interlayer distance exceeding 10 angstroms.

11. The base material for a disk roll according to claim 5 ,
wherein a content ratio relative to a mass of the base material for a disk roll is 30 to 45 mass % for the inorganic fiber, and is 20 to 45 mass % for the clay.
