Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to fired products such as tiles and bricks used for the interior and exterior of buildings, pavements, flooring materials, etc. It aims to make effective use of grinding waste, and is designed to perform the function of stopping the firing of tiles, bricks, etc. This relates to a fired product with anti-slip properties.

(Conventional technology) Fired products such as tiles and bricks are durable and have an excellent aesthetic sense, and are widely used for the interior and exterior of buildings, paving, flooring, etc. It has the disadvantage that it becomes slippery when it gets wet.

For this reason, various types of anti-slip tiles, bricks, etc. have been developed.

For example, particles are adhered to the surface of tiles, bricks, etc. with an adhesive to prevent slipping, or an uneven surface is formed on a molding machine for tiles, bricks, etc., and the tiles, bricks, etc. It is known that tiles, bricks, etc. are made by pressure-molding a molded body to form irregularities on the surface of the tiles, bricks, etc. to prevent slipping.

[Problem that the invention seeks to solve]

However, when it comes to tiles, bricks, etc. that are made non-slip by adhering particles to the surface with an adhesive, if the adhesion is not strong enough, the particles will peel off from the surface, making the anti-slip function insufficient. There was an inconvenience in not being able to perform.

In addition, when it comes to tiles, bricks, etc. that are made non-slip by forming irregularities on the surface with a molding machine that has an uneven surface, it is difficult to form extremely fine uneven surfaces, and as a result, it is difficult to form an extremely fine uneven surface. could not fully demonstrate its functions.

On the other hand, the grinding waste produced during grinding of stainless steel has not been used particularly effectively, other than being returned to the melting furnace as a raw material.

The present invention was devised in view of the above-mentioned problems and to eliminate the problems, and its purpose is to expose stainless steel grinding waste on the surface to provide an anti-slip function. It is an object of the present invention to provide a fired product which is provided with a non-slip surface so that the grinding material can be more fully utilized and at the same time effectively utilize the grinding waste generated during the grinding process of stainless steel.

[Means for solving problems]

In order to achieve the above object, the present invention has a structure in which stainless steel grinding waste is exposed on the surface of the fired product.

mm is preferable, and stainless steel grinding waste may be included in the ceramic clay or glaze.

Scatter ceramic clay consisting of. Ceramic clay made of feldspar, silica, clay, etc. is smaller than stainless steel grinding debris 11, so by utilizing the fact that it scatters before the stainless steel grinding debris 11, the air injection pressure is applied to feldspar, silica, clay, etc. The pressure is adjusted in advance to a pressure that will not scatter the stainless steel grinding waste 11, although the ceramic clay made of the material will scatter.

Since the belt conveyor 13 moves at a constant speed, the belt conveyor 13 moves under the injection port 15a at a constant speed and spreads the air approximately evenly over the entire main surface of the tile.
The stainless steel grinding waste 11 can be exposed substantially uniformly over the entire surface of the tile main body 12. Moreover, since the stainless steel grinding chips 11 exposed on the surface of the tile main body 12 have a diameter of 1 to 3 s+m, it is possible to form an extremely fine uneven surface on the surface of the tile main body 12. Feldspar, silica, produced by air injection,

An injection port 29a is provided at the tip of the gunshot injector 29, and the injection port 29a is directed downward at substantially right angles to the belt conveyor 27. The injection port 29a has an elongated opening in the width direction of the belt conveyor 27.
The opening length is approximately the same as the width of the opening. Then, the stainless steel grinding waste 11 is injected from the injection port 29a onto the surface of the tile main body 12 under constant pressure, so that the stainless steel grinding waste 11 is implanted on the surface of the tile main body 12. At this time, in order to prevent the air from being contaminated by the stainless steel grinding waste 11 injected from the gunshot injector 29, a highly sealed dustproof frame 30 is provided around the gunshot injector 29.

moves at a constant speed, the tile main body 12 can move under the injection port 29a at a constant speed, and therefore, the stainless steel grinding waste 11 is almost evenly distributed on the surface of the tile main body 120.
Stainless steel grinding waste 1 can be planted and exposed on the surface of the tile main body 12.
Since 1 has a diameter of 1 to 3 mm, it is possible to form an extremely fine uneven surface on the surface of the tile main body 12.

Then, the cleaning roller 33 removes dirt from the surface of the tile main body 12.
The tile main body 12 is discharged from the exit of the dustproof frame 30. After that, it goes through unglazed firing, glazing (or omitting unglazed firing and glazing), and final firing to create a non-slip tile.

Example 4 - Grinding debris generated during grinding of stainless steel
Stainless steel grinding chips 11 having a diameter of 1 to 3 ms+ are made by cutting to a size of IIl. This stainless steel grinding waste 11
Water is added and kneaded with ceramic clay made of feldspar, silica, clay, etc., and the mixture is kneaded using a vacuum clay kneading machine. As a result, air bubbles inside the base soil are removed, the spaces between each particle become dense, and the base soil is changed to have plasticity. The base soil containing the stainless steel grinding waste 11 produced in this way is pressure-molded using a tile forming machine to form the base soil including the stainless steel grinding waste 11 and the stainless steel grinding waste 11 and the stainless steel grinding waste 11. Create a base soil that does not contain stainless steel grinding waste 11
The tile main body 12 may be formed by layering a base soil containing no stainless steel as a lower layer and a base soil containing stainless steel grinding waste 11 on the surface layer. Further, a material may be added that increases the shrinkage of the ceramic clay made of feldspar, silica, clay, etc. during firing.

Next, the stainless steel grinding waste formed in this way 1
1 is fired. By firing, the ceramic clay made of feldspar, silica, clay, etc. contracts, and as a result, the stainless steel grinding waste 11 is exposed on the surface of the tile main body 12, and an extremely fine uneven surface is formed on the surface of the tile main body 12. will be formed.

In the above embodiments, the case of tiles has been described, but the present invention can be applied to bricks as well. Note that during the firing process, the stainless steel grinding waste 11 becomes soft and sharp corners become smooth, so that they will not be damaged.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, stainless steel grinding waste is exposed on the surface of fired products such as tiles and bricks, so extremely fine irregularities are formed on the surfaces of fired products such as tiles and bricks. Moreover, the stainless steel grinding chips exposed on the surface of the fired product such as tiles and bricks are integrated with the fired product, so that the stainless steel can be firmly attached to the surface of the fired product without cutting or peeling. Grinding debris can be fixed. Therefore, it is possible to generate good frictional resistance on the surface of a fired product such as a tile or brick, and to fully exhibit its anti-slip function. In conjunction with this, the stainless steel grinding chips used as anti-slip materials are hard and will not break, and have excellent durability and wear resistance, and have excellent properties that can last for a long time. It can exhibit good anti-slip function. In this way, the anti-slip function can be fully demonstrated by using stainless steel grinding waste, which has not been used effectively other than being returned to the melting furnace as a raw material. This has extremely novel and beneficial effects.
