Description

Detailed Description of the Invention (Field of Industrial Application) The present invention provides conductive properties by melting a conductive melt onto the surface of the tile in a kiln in order to impart conductive properties to ceramic tiles of arbitrary shapes. The present invention relates to a method for producing a conductive tile that prevents damage caused by static electricity.

(Prior art) Conventional tiles are made of ceramic material and are fired and shaped as appropriate with or without glazing, and are used as tiles for the exterior and interior of buildings such as buildings and houses, as well as for floors. However, these uses only utilize the physical and chemical properties of tiles such as weather resistance and abrasion resistance, as well as their decorative properties. Applications to prevent static electricity damage in places where semiconductors are handled such as computer rooms, dirt and dust in clean rooms and places where precision equipment is handled, flammable gases, solvents or explosives, and chemicals and solvents in laboratories. For use in rooms where materials are handled, factories, storage areas to prevent ignition caused by electrical discharge, operating rooms, and powder bagging.

It has become unsuitable for applications such as preventing electric shocks in places where paper, etc. are rolled up, and cannot be used in the above places, so conductive fibrous mats or resin mats are currently being used. Although I am using it.

There are problems with abrasion resistance, chemical resistance, weather resistance, etc., which limits the range of use, and there is a desire for something with conductivity that can be used in a wider range.

(Problems to be Solved by the Invention) A conductive glaze is manufactured to impart conductive properties to ceramic tiles, and this is welded to a ceramic tile of any shape to impart conductive properties to prevent static electricity damage. Prevents dust, dirt, ignition caused by electrical discharge, electric shock, etc.
It can be used in a wide range of fields and has the inherent wear resistance of tiles.

-4 We aim to solve these problems by manufacturing tiles that are chemically resistant and weather resistant.

(Means for Solving the Problems) The present invention involves molding tiles of arbitrary shapes from ceramic materials,
A method for producing a conductive tile, which comprises applying a conductive glaze to the outer surface of the tile and then welding it by firing in a kiln to impart conductivity to the outer surface of the tile. This is a method for manufacturing tiles whose surface resistance prevents damage caused by static electricity, and also satisfies a resistance value that is considered desirable from the viewpoint of preventing low-voltage electric shocks.

(Example) First, the first to third embodiments will be explained.

In the first step, a conductive glaze slurry is manufactured using the following blending ratios (weight ratios).

Next, in the second step, the glaze slurry is applied to a pottery base made of 5-tiles of arbitrary shapes, and in the third step, each tile is heated in a kiln at 870"C to 1000°C. C
The conductive melt is welded onto the tile base by firing at a temperature of 7° or more to form a conductive tile, which meets the Japanese Industrial Standard A32.
09 r Ceramic tiles” standards.
Moreover, the surface resistance is 10 to 10 Ω in the first embodiment, 10 to 10 Ω in the second embodiment, and 10 to 10 Ω in the third embodiment, and the resistance value prevents damage caused by static electricity.
Furthermore, it satisfies what is considered to be desirable from the viewpoint of preventing low-voltage electric shock.

Next, a fourth embodiment will be explained. In the first step, a conductive glaze slurry is produced using the following blending ratio (weight ratio).

6- Next, in the second step, the above glaze slurry is applied to the green base material which is made into tiles of arbitrary shape by press molding, and further, in the third step, it is fired in a kiln at 1250''C-1800°C. A conductive tile was formed by welding a conductive melt onto the tile base (7).

The tiles manufactured as described above have a surface resistance of 10 to 10 Ω, and have a surface resistance of 10 to 10 Ω, which is the same as the first embodiment described above, and has a surface resistance of 10 to 10 Ω. Furthermore, it also satisfies what is considered desirable from the viewpoint of preventing low-voltage electric shock.

(Effects) The present invention coats the base surface of ceramic tiles by welding a conductive melt in a kiln in order to impart conductive properties to the base surface of the ceramic tile. It is necessary to prepare semiconductor factories, computer rooms, clean rooms, precision equipment that can prevent dirt and dust, and to prevent ignition caused by electrical discharge, such as flammable gases, solvents, explosives, chemicals such as laboratories, etc. Places where solvents are handled,
Furthermore, it can prevent electric shock and is suitable for use in operating rooms, places where powder is packed into bags, paper is rolled up, etc., and it has the same properties as conventional glazed ones. However, the physical properties of the glaze also vary depending on the glaze composition ratio, the tile base used, and the firing temperature.
This is a method for manufacturing tiles that have a number of effects such as not only chemical properties but also electrical conductivity that can be appropriately controlled.
