Description of the invention: [Technical field to which the invention pertains] The present invention relates to a disc for the manufacture of flat glass and a substrate thereof. [Prior Art] The flat glass is produced by continuously supplying a surface melt to a device, causing it to be under a braiding machine in the apparatus, and performing cooling hardening during the downflow. The disc roll functions as a tension-locking cylinder and is used to force the strip-shaped glass melt to be held below. In general, a disc roll is a sheet in which a plurality of sheets of a cardboard (a plate-shaped formed body, a base material) are punched into a shape, and inserted into a shaft as a rotating shaft to form a roll-like laminate. The flanges disposed at both ends are press-fitted and fixed as a whole. The outer peripheral surface of the disc sheet functions as a conveying surface of the glass melt. Disc rolls are the ones that send ribbon glass melts. Therefore, not only heat resistance, flexibility, hardness, but also scratching of the glass surface are required, and disc sticks containing fibrinous inorganic fibers, mica, and clay are known. Specialized (Patent Documents 1 to 3). In general, the enamel roll is an aqueous slurry of a raw material produced by a suction dehydration molding method or a papermaking method depending on whether the water repellency is good or not. The papermaking method can produce a large sheet, so the efficiency is low, but the water filtration must be good.

The ceramic fiber is contained in an amount of 20 to 38% by weight, preferably 25 to 38% by weight, more preferably 25 to 35% by weight. When the ceramic fiber is less than 20% by weight, the heat resistance is lowered. When the ceramic fiber exceeds 38% by weight, the amount of voids is increased, so that the wear resistance may be deteriorated. The ceramic fiber used in the present invention contains 40% by weight or more and 60% by weight of alumina of 101111294 5 201247564 or less, preferably 45% by weight or more and 55% by weight or less. Further, the Tao Jing fiber system contains 4 g% by weight or more and 8% by weight or less of oxidized stone, and Μ is Μ by weight or more and 55 parts by weight. the following. The fibers may be used alone or in combination of two or more. The average fiber straightness of the ceramic fiber is usually about 2 to 5 inches. The raw material of the ceramic fiber usually contains an unfibrillated material (clear ball), and the ball is reduced by using a gas or a wide-range method to reduce the ball. The ceramsite fiber used for the present invention contains only 5 parts by weight or less, preferably 2% by weight or less, of 45 μl·· slag balls (unfibrated material). A disc roll made using a slag ball has a scratched glass surface. The size of the slag ball is usually around 45~5_μιη.

If the swelling J is not contained, the deteriorating property is increased, and the water content is deteriorated. Conversely, the thermal expansion of the inlaid shaft is increased~· The expansion ratio is low, ^ & The disc sheet and the metal phase cannot track the elongation of the shaft, resulting in 磲101111294, and Hebi 6 201247564. On the other hand, the mica system forms an extremely thin layer structure, and once heated, a crystal transformation state occurs, and at this time, there is a tendency to expand in the layer direction, and the axis of the disk is caused by the expansion toward the layer direction. Tracking improvement in thermal expansion. As mica, muscovite (K2Al4(Si3Al)2O20(〇H)4), biotite, phlogopite (phl〇g〇pite; K^MgJSiAlhOWOH) 4), sodium mica, lithium mica, fluorosynthetic mica can be used. Etc. However, considering the above traceability, it is preferably muscovite. The substrate comprises 20 to 40% by weight, preferably 25 to 35% by weight, of mica. When the amount of the mica is less than 20% by weight, the tracking property of the thermal expansion of the shaft is lowered. If it exceeds 40% by weight, it is difficult to uniformly disperse into the slurry, and there is a fear that the variation in the physical properties of the disk substrate is increased. The substrate of the present invention may contain an agglomeration aid or an organic binder in addition to the above components, without departing from the effects of the present invention. As the organic binder, organic fibers (pulp) and starch are preferred. When the organic fiber (pulp) is contained, the compression property can be exhibited, and the amount can be, for example, 2 to 10% by weight or 6 to 10% by weight. Further, if the temple powder is contained, the strength of the disc material can be expressed, and the amount can be, for example, 1 to 1% by weight or 1 to 4% by weight. In the base material of the present invention, as the inorganic component, the ceramic fiber, the woody soil, the % soil, and the mica may be 90% by weight or more and 95% by weight. /. The above, 98% by weight or more, and 1% by weight. In the substrate of the present invention, the above-mentioned components are contained in the above range, and even if the amount of the inorganic fibers is small, a disc roll which is maintained in a heat resistance and strength balance can be obtained. 01111294 7 201247564. The substrate can be preferably obtained by making the water-containing material which is not formed into a plate-shaped material. That is, it can be (four) system... the efficiency of the gossip is lower than that of the j-hunting, including the established and mica, and (4) the water containing the scales, the homogenizer binder, etc., and the pro-fiber, plate-like advancement m The quaternary machine forms the aqueous slurry into a shape of a slab and is dried to obtain a base set, and is usually 2 to 1 〇 mm. The thickness of the substrate can be appropriately determined: a method for producing a wide roll, which will be described. Usually, from the soil/disc sheet, a plurality of the disc sheets are inserted into a metal (for example, iron (4), and made into a (four)-like laminate, and the flange of the butterfly configuration = pressurizes the pair of ends (four) In the state in which a certain number of (4) is applied to the disc ride, (4) be carried out as needed (4). Then, the disc roll is obtained in a manner other than the sheet in the manner of achieving the predetermined diameter. In the structure of the cylinder, there is a size in which the entire surface of the shaft is covered by the disc sheet, a part in which the glass is in contact with the shaft is covered by the disc sheet, and a specification including a single shaft is included.

The roller was increased in diameter at a density of 1.25 g/cm3, and maintained in a heating furnace maintained at 9 〇〇i>c for 10 hours, and then naturally cooled to room temperature. The cooled sample was cut into 5 x 5 x 20 mm as a measurement sample. The thermomechanical analysis device rTMA83l〇 manufactured by Rigaku Electric Co., Ltd. was used to raise the temperature from room temperature to 9 Torr at a rate of 5 ° C/min in air.

For the substrate for the ceramic fiber disc roll, cut a dish of 3 mm in length and 5 in length 111111], and the plate is made of stainless steel. The sample was compressed and fixed in such a manner that the thickness reached 2Qinm and the density was 101111294 201247564 to 1.35 g/cm3. The sample was heated at 600 ° C for 5 hours and then cooled to room temperature 25 ° C. The recovery length when the compression force applied to the disc is released is divided by the original length to determine the recovery rate.
