Conventionally, baking shelves used for example when firing objects to be fired, after loading, when loading and unloading before and after firing, or when transporting them are heavy and made of ceramic material with poor impact resistance, so they cannot be loaded or unloaded or transported. Not only is it inconvenient when transporting, etc., but the frequency of damage caused by hitting it against the other side is small.If only the shelf board is damaged, it is not a problem, but it can also have a negative impact on the object to be fired. There are quite a few, and for those in the industry, I was hoping for a baking box that would be relatively difficult to destroy and convenient to carry, but it was large enough.

This manufacturing method involves creating a unit assembly molded body with a desired unit contour shape, which is made of partition walls made of an organic material that easily disappears during ceramic firing, allowing the desired shape to be easily obtained. Is there a method of forming raw ceramic foam inside the wall and firing it to eliminate the organic material partitions, and automatically mass-produce the small contour shapes of each unit? Even if a porous material is obtained through a process, the pores formed by the foaming reaction on its outer surface or ridges will still be exposed, and if it comes into contact with something in this exposed state, it will be damaged or scratched. In addition to the risk of abrasion, additional processing such as dimensional adjustment and coloring is required when used as a building material or -f heating material. It became necessary to develop a manufacturing method. Furthermore, the 8th
The figure is a photograph substituted for a drawing of a ceramic porous body with a particularly high degree of foaming obtained by utilizing the invention disclosed in Tokiri No. 57-25460, and an enlarged view of an unpolished fired product. This shows the direction of the situation.

In other words, it is possible to maintain a smooth surface on the entire outer surface and ridge lines, has a porous structure that provides effects such as heat insulation, and is a fire-resistant material, so it can be used as a building material. In short, applications that require a smooth, reinforced, and dense surface on part or all of the surface, and require porous properties such as porosity or heat insulation, and also require the material properties of ceramics. All applicable. Therefore, various shapes such as rod-like shapes as well as plate-like shapes can be obtained by this type of manufacturing method.

As described above, the reinforced ceramic porous body according to the present invention has
Its production involves injecting a ceramic foaming compound into a mold and causing it to foam. After reaction hardening, the raw ceramic foam is taken out of the mold, dried, and part or all of its outer surface and ridge lines are polished to remove the coating. It is obtained by clogging the pores of the polished part with abrasive powder and firing it.It has a porous structure and forms a dense smoothness-reinforcing layer in the polished part. be. Therefore, in addition to being relatively hard to break and convenient to handle, it is also beautiful and can be colored, and has a porous structure that makes it easy to use for baking shelves. It can be applied to thermal theory and various other fields by taking advantage of the above advantages.
