【発明の詳細な説明】 この発明は、工業炉の目地シールに用いられるパツキン

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a packing box used for sealing joints in industrial furnaces.

Conventionally, for example, ceramic fiber felt or bulk was used as a joint sealing material (3) to fill the gap between the radiant tube (1) and the furnace wall (2) of a continuous baking furnace as shown in the drawing. Compression filling is used to fill the ceramic fibers, but the drawback is that if the ceramic fiber felt or bulk is simply compressed and filled, the joints will open due to heat shrinkage at high temperatures, making it impossible to form a sufficient seal.

This invention was made to solve the above problems, and takes advantage of the characteristics of heat-resistant fiber materials such as ceramic fibers, and almost never shrinks when heated at high temperatures. The purpose of this invention is to provide a packing for industrial furnaces that can reliably maintain the sealing properties of joints.

A mixture consisting of 0 to 95% by weight of unexpanded vermiculite particles, 5 to 30% of unexpanded vermiculite particles, and an appropriate amount of a binder is formed into a sheet and is appealing to cattle.

A preferred method for producing the packing material of this invention is to disperse heat-resistant fiber No. 4 I and a binder such as unexpanded vermiculite particles in water to form a slurry, and then to form a slurry into a sheet. By using this paper-making method, it is possible to produce a packing sheet in which fibers and vermiculite are uniformly mixed.

When the 4N sheet-shaped butting material is wrapped around the radiant tube described above and the radiant tube is wrapped around the entire furnace wall to heat the furnace, the temperature is 3°. At about ℃, the packing particles begin to expand, so the entire sheet gradually expands, filling the gap between the radiant tube and the furnace wall, effectively sealing the gas inside the furnace. The wet I-shaped sheet containing water is easier to apply because it has softer properties.

If the weight of the unexpanded vermiculite exceeds 50 wt.% (by weight% or more), the sheet will not expand sufficiently, and if the heat-resistant fiber material exceeds 70 wt.% of the unexpanded vermiculite, heat shrinkage at high temperatures will occur. Since this tends to increase the heat resistance of the sheet, a suitable range is 5 to 60%. The binder is used to improve the handling properties of the seal, and its compound edge is 0.
~30% by weight is suitable. 5. In order to increase the expansibility of the sheet, plastic heat) is added to the membrane microcapsule (Microvar, Matsumoto 111111 fF41).

As described above, according to the present invention, 70 to 95% by weight of heat-resistant inorganic fibers and 5 to 95% of unexpanded vermicular fibers are used.
Since the mixture consisting of 50% by weight and an appropriate amount of binder is formed into a sheet, when used as a sealing material for joints in a uni-furnace construction, the above-mentioned vermigrain (i! +'l expands, and the entire packing sheet swells to function as a self-sealing function that fills the gaps between 1 and 0 of the joints, resulting in an excellent joint sealing effect.Especially when used on the ceiling of a furnace. By increasing the laminar friction force due to its expansion, the seal itself can be prevented from falling off.
