Description

DETAILED DESCRIPTION OF THE INVENTION This invention provides a new method for forming fired products, in particular, filling and adhering firing clay particles and Portland cement powder between the constituent fibers of a carbon fiber sheet, and applying water to one core sheet. This invention relates to a method for forming a reinforced and fired product containing glass and firing it.

Accordingly, the present invention makes it possible to provide wall tiles, baths, chairs, and other tile products that are made of a reinforced fired material that has bending strength, impact resistance, and tensile strength.

Furthermore, the present invention makes it possible to create thin fired products, especially ceramic crafts, building materials, etc. due to the characteristics of carbon fiber, which has heat resistance, elasticity, and high-temperature strength that glass fiber and ceramic fiber do not have. It was designed to do so.

Therefore, in order to achieve the appropriate and purposeful effect of the lighting properties, Honsei Raaki has developed the gist of its composition between the constituent fibers of the carphone fiber sheet and the clay particles for firing.
A sheet filled with portland cement, impregnated with water glass, and placed on a fired point,
Considerable design changes were planned to accommodate the gist of the configuration.

Hereinafter, the details of the present invention will be explained with reference to the drawings. (1)
is a carbon fiber sheet made of carbon fiber non-woven fabric, woven fabric, knitted fabric, etc., and this sheet (1
) In order to fill and adhere a mixture of clay particles for firing and Portland cement powder at a certain ratio between the constituent fibers of the sheet (1), the sheet (1) is attached to a conveyor belt-like mesh (3).
The mesh body (3) 8 is moved by a damper (6) which vibrates so as to pass under the potper (2) which supplies the fired clay particles and Portland cement powder mixed as described above. The calcining clay particles and Portland cement powder are filled between the constituent fibers of the carphone fiber sheet (1) and then guided into a container containing water glass (4). 1) is impregnated with water glass (4), and then press-molded into various desired shapes and fired in a furnace, especially in a non-oxidizing atmosphere furnace. To explain a typical embodiment of the present invention shown in FIG. 3, a sheet (1) impregnated with firing clay, Portland cement powder, and water glass (4) is press-molded, ) a and the inner container (1) b are fired, and the inner container (1) b is fitted and assembled into the outer container (1) a, and the inner container (1) aii>b has a structural gap VC insulating foam material (
7) was injected and filled into a bathtub.

Next, the tile shown in Figure 4 is made by molding tile-shaped joints (9) on a carphone fiber sheet (1) that has been treated with firing clay, Portland cement powder, and water glass (4), and then firing it. be.

Furthermore, in the example shown in FIG. 5, a seat plate (1) c of a chair is fired in the same manner, and an alkali-resistant glass fiber reinforced concrete IJ-t (8) is coated on the back side of the plate (1) c. The wood was sprayed and reinforced with rock-strength material, creating a chair with a ceramic-like surface that is not only visually appealing.

The present invention has a unique structure on the board, in particular, clay particles for firing and portland cement powder are filled and adhered between the constituent fibers of the carbon fiber sheet base, and water glass is applied to the sheet base. By firing without impregnation, the following +tf% effect was achieved. .

That is, the present invention is a carbon fiber 'E-Mo' which has heat resistance, elasticity and high temperature strength, and the fired product has strength against bending, and also has a combination of Bortland cement and water. The mixture of glass made it waterproof.

In addition, the clay for firing was able to create a porcelain board-like embankment and achieve good external slope 4 aesthetics.

In the town, in the present invention, the carbon fiber sheet (J-1) is surrounded by water glass during firing, which prevents carbon from burning, and also prevents the burning of clay. This prevents the wood from aging as it warms up during storage.

Next, the present invention has been able to expand the fields of ceramic crafts, vat-dyed parts, etc.

The forming method used in the present invention includes molding, folding, gluing, cutting and pasting, etc. The sheet thus provided can be subjected to various firing processes depending on the purpose, such as conventional glazing, Painting with special glazes, underpaintings, overpaintings, etc.
It enables firing based on surface treatments tailored to the purpose, such as raster finishing or unglazed firing, and allows the incorporation of all methods that can be applied to general ceramic products.

In addition, when performing firing based on such surface treatment, firing should be carried out in a vacuum furnace or a nitrogen gas-filled furnace, in particular, in a state that minimizes the risk of burning out carbon fibers that do not contain so-called oxygen content. This is how it was done.

Incidentally, such atmospheric furnaces are not specified as such, but may be other structural furnaces or gas-filled furnaces that are unlikely to cause oxidation burnout.
Further development methods are planned.

The fired ceramic board thus constructed is sufficiently reinforced with carbon fibers, and is said to have particularly good load-bearing properties, bending resistance, and water resistance, and is widely used as a composite material for ordinary decorative materials. It is planned to have many uses.

As stated in the paper, the present invention relates to the provision of a method for forming a strengthened fired product which has uniform wall thickness dimensions and can be freely shaped and fired.
