Abstract

PROBLEM TO BE SOLVED: To efficiently produce a brick like tile excellent in design effect, execution properties and freeze resistance by performing cutting treatment shaping off the surface of a molded object non-uniformly, powder falling treatment allowing a tile body and sherd to non-uniformly fall on the surface of the molded object and a process baking the molded object. SOLUTION: A tile molded object is molded under a usual tile molding condition by a press molding machine 1 and the molded object 2 obtained in the molding process is subjected to blast treatment spraying sand, steel balls or sherd on the surface of the molded object to apply uniform unevenness to the surface of the molded object. After blasting treatment, shaving treatment is applied to the molded object 2 to non-uniformly shave off the surface thereof. After non-uniform surface shaving treatment, a tile body and/or sherd is allowed to fall on the surface of the molded object 2. After powder falling treatment, glaze 5 is applied to the molded object.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing brick-like tiles, and more particularly to a method for efficiently manufacturing attractive brick-like tiles by using an ordinary tile base material.

[0002]

2. Description of the Related Art Brick construction has a profound, tasteful and unique design. Therefore, tiles made by slicing bricks have been put to practical use as interior and exterior tiles in order to make the best use of the texture of the bricks.

Conventionally, such brick-like tiles have been formed by press-molding a kneaded material (for example, a kneaded material containing a large amount of silica) having a coarse grain size and hard to be hardened, and then firing the sintered block to a thickness of the tile. It is manufactured by cutting.

[0004]

In the above-mentioned conventional method for manufacturing brick-like tiles, since cutting is performed after firing, the number of manufacturing steps is large and the production efficiency is poor. Since the cutting process is performed after firing, it is not possible to provide the back foot on the back surface of the tile. Therefore, it is not suitable as a tile for sticking construction. Since the degree of sintering is low, the water absorbency of the substrate is high and the freeze resistance is poor. Therefore, it is difficult to apply it to the outer wall construction. The design of the resulting tile is not fully satisfactory. There are drawbacks.

An object of the present invention is to solve the above conventional problems and to provide a method for efficiently producing a brick-like tile excellent in designability, workability and frost damage resistance.

(Ii) Sponge or brush 3 applied to the surface of the molded body 2
Stop rotating on the way; (iii) Sponge or brush 3 applied to the surface of the molded body 2
The number of rotations is changed on the way;

After this non-uniform surface scraping treatment, the surface of the molded body 2 is subjected to a powder dropping treatment for non-uniformly dropping the tile clay and / or selben. The following compound I or II is mentioned as a preferable mixture of the powder 4 used in this powder removing treatment.

Powder Mixing I Ceramics of ordinary pottery preparation: 100 parts by weight Serben: 10 to 50 parts by weight Pigment: 20 parts by weight or less Powder blending II Serben: 100 parts by weight Pellets of usual ceramics preparation: 10 to 90 parts by weight Parts Pigment: 20 parts by weight or less In the powder-removing treatment, it is preferable that the powder having the above-mentioned composition is sprinkled non-uniformly with the composition of 2.0 to 10.0 g per 100 cm ² of the surface of the molded body.

The powder used for the powder removing treatment may be a powder mixed uniformly, or may be a powder mixed nonuniformly. Further, the kneaded clay, selben, or pigment may be sprinkled on the surface of the molded body separately.

After the powder removing process, the molded body is glazed. This glaze may be performed on the entire molded body or partially.

In the present embodiment, the blasting, shaving, powder dropping and glaze treatment steps after molding can be carried out continuously by moving the molded body 2 by the conveyor 6.

After glazing, the tiles are dried and fired to obtain brick tiles. When firing by RHK (roller hearth kiln), 1-8 at a temperature of 1100-1300 ° C
It is preferable to bake for about an hour, and in the case of TK (tunnel kiln), it is preferable to bake at 1100 to 1300 ° C. for 10 to 60 hours, especially about 24 to 48 hours.

The method shown in FIG. 1 relates to the method of claim 2, in which the surface of the molded body is sequentially blasted, cut, and cut.
The powder is removed and each process of glaze is performed. Claims 1 and 3
The method of ~ 8, by appropriately changing the decoration processing,
A brick tile is obtained by omitting one or two treatments.

That is, according to the method of claim 1, as shown in FIG. 2, after the surface of the molded body is scraped off, the powder is shredded, then glaze and fired.

According to the method of claim 3, as shown in FIG. 3, the surface of the molded product is subjected to a powder-removing treatment, followed by a shaving treatment, followed by glaze and firing.

According to a fourth aspect of the present invention, as shown in FIG. 4, the surface of the molded product is blasted, then powder is removed, then scraped, and then glazed and fired.

According to the method of claim 5, as shown in FIG. 5, the surface of the molded body is scraped off, blasted, then powdered, and then glazed and fired.

According to a sixth aspect of the present invention, as shown in FIG. 6, the surface of the molded product is subjected to powder-removing treatment, followed by shaving treatment, then blast treatment, and then glaze firing.

According to the method of claim 7, as shown in FIG. 7, after the surface of the molded body is powdered off, it is glazed (this glaze may be performed on the entire surface or partially). Then, it is subjected to a scraping treatment, and then glazed and fired.

According to the method of claim 8, as shown in FIG. 8, the molded body is subjected to a powder-removing treatment, and then is glazed and fired.

In any of the methods shown in FIGS. 2 to 8, in the steps of molding, shaving, powder dropping, blasting, glazing, and firing, the same treatments as those described in the method shown in FIG. 1 are performed. It can be carried out.

In the method shown in FIGS. 2 to 8, the glaze treatment is effective not only for the decorative effect by the glaze but also for adhering the powder in the powder removing treatment to the surface of the molded body, but it is not always necessary. Instead, the powder may be removed, scraped or blasted, and then baked without performing glaze.
