Description

Ceramic block and its manufacturing method {Ceramic block and its process}

The present invention relates to a ceramic block and a method of manufacturing the same.

In general, the clay block manufacturing method can be roughly divided into a dry manufacturing method and a wet manufacturing method. Among them, the dry manufacturing method is a powder raw material mixture consisting of kaolin, feldspar, pottery stone, clay, feldspar, etc. is put into a press mold and molded by pressing, and after the drying step may be subjected to a see-through step if necessary. Firing takes place at a temperature of 1200 ° C. The wet manufacturing method differs from the dry manufacturing method in that the raw material mixture containing about 20% of moisture and having a viscosity is continuously extruded using a vacuum grinder.

However, these methods are not only difficult to produce blocks with fine and fine patterns, but also unsatisfactory in strength, in a manner suitable for producing blocks without patterns or simple and regular patterns.

In addition, it is possible to produce a product with a delicate pattern by applying the general ceramic production method to the block as it is, but in this case, it is difficult to produce a uniform product due to doubling phenomenon, and also to be used for various purposes such as flooring. The strength and texture are not suitable, so you need to choose different materials.

Accordingly, an object of the present invention is to provide a block and a method for producing the same, which can be used not only as a wall but also as a flooring material by selecting a base material suitable for a purpose while applying a ceramic production method to a block. In addition, the appearance is as beautiful as traditional Korean ceramics, but does not cause problems such as hungry, the material is to use natural materials harmless to the human body and to provide an eco-friendly block and its manufacturing method.

The present invention relates to a ceramic block and a method for manufacturing the same, which are manufactured through a process of manufacturing and processing a combination clay, forming and drying, roasting a glaze, preparing and glazing glaze, and chaebol, and the detailed method is as follows.

As such, by adding diatomaceous earth to the combination soil, the warpage of the block can be minimized, antibacterial and deodorizing effects can be obtained, and humidity control and far infrared ray emission effects can be enhanced.

The above-mentioned combination soil is used after pulverizing, refining, degassing, and aging after mixing, followed by filtration, compression and vacuum processing.

[Manufacturing Process 2] Molding and Drying

The combination soil is put into a press mold engraved with a desired pattern and is molded by applying pressure. At this time, the size of the mold should be determined in consideration of the shrinkage rate of the combination soil, the body is about 10% shrinkage.

After molding, the drying process is carried out, and if the natural drying in a shaded place takes about 30 days, when using a drying room takes about 4 days.

[Manufacturing Process 3] Grilling

The dried product is put into a kiln and fired at a temperature of 900 ° C. for 8 hours.

[Manufacturing Process 4] Preparation and Milking of Glaze

Glaze is manufactured by mixing natural materials consisting of Mungyeong yakto, mukborae, nerb wood, oak wood, apple wood, pine wood and water to a weight ratio of 1: 2-4. As an example of the mixing ratio for the natural material, 14% by weight of mugwort, 4% by weight of elm wood, 2% by weight of Mungyeong Yakto and 80% by weight of water, transparent brown, 12% by weight of oak wood, 4% by weight of Mungyeong yakto , 4% by weight of mussels and 80% by weight of water are dark brown, 18% by weight of Mungyeong clay, 1% by weight of apple tree material, 1% by weight of pine material and 80% by weight of light brown, 16% by weight of Mungyeong clay %, Apple wood material 2% by weight, pine wood material 2% by weight and 80% by weight of water can produce a glossy black glaze.

Glaze is applied only on the upper part so as not to interfere with the adhesion during construction, and the side surface should be oiled only to a part away from the lower part. After applying glaze, it can be wiped off to show the effect of double color, and it can also change the color by adjusting the firing temperature when grilling.

[Manufacturing Process 5] Grilling chaebol

The finished product is put into a kiln and calcined at 1200-1300 ° C. for 24 hours to prepare a ceramic block.
