Description

Manufacturing method and ceramic products of ceramic products using sawdust

In general, conventional general ceramic products such as interior materials, exterior materials, ceramics, earthenware, etc. have been produced using clay as main raw materials, but it is difficult to secure expensive clay raw materials that are extinguished daily. Tiles of mass produced in mass form do not have many problems in storage and construction.

In recent years, decorative construction of artistic sculptures has been attempted on the inner and outer walls of buildings in order to create a more comfortable and brighter living environment.In such construction environments, tiles of various designs that are lighter and of higher quality than existing tiles are inevitably required. It is becoming.

On the other hand, pottery and earthenware have been widely used as tableware, etc., but the demand for such improvements is increasingly urgently required due to expensive purchase costs and handling difficulties.

The present invention has been made in order to improve the conventional problems as described above, when manufacturing a ceramic product such as tiles and earthenware, tableware, ceramics, etc. for the existing building, the clay and sawdust mixed composition to a certain ratio product It aims to provide lightweight and diversified products and to supply high quality ceramic products at a lower cost.

The present invention, in the manufacture of a variety of ordinary ceramic products, kneading the mixture by mixing the main ingredients of clay and sawdust in a mixing ratio of approximately 6: 4, and molded into a predetermined shape after the first firing and pigmentation after firing the product As will be completed, looking at the specific method of the present invention and the tiles and ceramics as an example as follows.

Example 1.

(1) Tile manufacturing method

1. Mix 60% of the clay in the slip state and 40% of the sawdust in the form of fine particles.

2. The mixture is kneaded first and second in a refining machine.

3. Adjust viscosity and moisture to make molding easier.

4. Cut the dough, such as cylindrical and square, discharged from the refining machine to the appropriate length.

5. Mold the dough cut in the press.

6. Dry the molded tile.

7. Put the tile in the kiln and begin firing at 900 ℃ ~ 980 ℃.

8. Soak in 30% pigmented pigment and 70% brine solution.

9. Put the tile into the kiln and bake the ash at 1200 ~ 1300 ℃.

Looking at the tile manufacturing method in detail, after preparing the clay in a thick state, a large amount of fine sawdust discarded is collected and mixed with the clay in the slip state. At this time, the weight of the finished product can be adjusted by adding or subtracting the mixing ratio of sawdust.

The mixture is made of the first and second kneading in the refining machine, the dough time is properly considered in accordance with the amount of dough to adjust the viscosity and moisture to facilitate the molding, the viscosity can be adjusted according to the amount of water input and the dough cycle. Is common.

When the dough is completed in the refining machine, according to the frame shape of the discharge hole attached to the refining machine, when the anti-book products of various shapes such as cylinders and squares are discharged, they are cut to an appropriate length, and the cut dough is put into a compression press to form various tiles. After shaping, drying, removing foreign matters, and putting it in the kiln for the first firing, the sawdust mixed with clay is lost by high temperature and fine pores are generated inside the tile, which makes the weight lighter.

The first fired tiles are immersed in a solution mixed with coloring pigments and brine to be sufficiently penetrated into the interior pores of the tile, and then taken out immediately after the chaebol firing without a separate drying process, the tiles are produced. It is light and has high strength and excellent gloss without additional glazing and can be more convenient than conventional tiles. In particular, it is possible to easily produce various tile shapes at low cost and widen the artistic surface range of installation sculptures.

Example 2.

(2) pottery manufacturing method

1. Mix 70% of slip clay and 30% fine grain sawdust.

2. The mixture is kneaded first, second and third in a refining machine.

3. Adjust viscosity and moisture to make molding easier.

4. Cut the dough, such as cylindrical and square, discharged from the refining machine to the proper length.

5. The cut dough is molded in a mold.

6. Dry the molded bowl.

7. After decorating work such as inlay, put the bowl in the kiln and begin firing at 900 ℃ ~ 980 ℃.

8. After coloring and decorating, soak in glaze and take out.

9. Put the bowl in the kiln and bake chaebol at 1200 ℃ ~ 1250 ℃.

Looking at the manufacturing method of the pottery in detail as in the manufacturing method of the tile, after preparing the clay in a thick state, a large amount of fine sawdust discarded is collected and mixed with the clay of the slip state. At this time, the weight of the finished product can be adjusted by adding or subtracting the mixing ratio of sawdust.

The mixture is made in the pulverizer 1, 2, 3rd dough, the dough time is properly considered according to the amount of dough, the viscosity and moisture is adjusted to facilitate molding, the viscosity can be adjusted according to the amount of water input and dough turn The kneading method is common.

When the dough is completed in the refining machine, when various types of dough, such as a cylinder and a square, are discharged into the mold according to the frame shape of the discharge hole attached to the refining machine, the cutting is cut to an appropriate length, and the cut dough is put into a mold and molded into various shapes. After drying and removing foreign matters, and after finishing the decoration such as inlay and put in the kiln first firing, the sawdust mixed with clay is lost by the high temperature and fine pores are generated inside the pottery is light weight.

When the first firing pottery is colored and glazed immediately after firing without separate drying process, various pottery products are completed. The pottery produced through the manufacturing method is light, has high strength, has excellent gloss, and is cheaper than conventional ceramics. As it can be produced, consumers will be able to access high-quality pottery such as tableware without hesitation.

As described in detail above, through the manufacturing method of the tile, to lower the manufacturing cost by reducing the clay material, and to reduce the weight applied to the building as the weight and diversity of the tile, to help ensure the stability of the building and to facilitate construction It is possible to provide a wider range of artistic expression of sculptures.

In addition, through the manufacturing method of the pottery, by lowering the manufacturing cost and achieving a lighter weight of the pottery by reducing the clay material, consumers can easily purchase high-quality pottery at low cost.

As described above, the present invention is a very useful invention that is expected to be applicable to the production of new ceramic products by providing a groundbreaking manufacturing method by escaping a conventional ceramic product manufacturing method.

In the present invention, when manufacturing various ceramic products such as tiles, ceramics, earthenware, etc. for building and exterior materials, the sawdust is mixed and kneaded in clay at a predetermined ratio, and after being subjected to a series of molding and baking processes, It is an object of the present invention to provide a method for manufacturing various types of ceramic products that are light and of good quality.
