Description

Manufacturing method of clay brick using charcoal powder and clay powder {MANUFACTURING METHOD OF CALY BRICKS USING A CHARCOAL POWDER AND CLAY POWDER}

The present invention relates to a method for producing clay brick using charcoal powder and clay powder, and more particularly, in the manufacture of clay brick, a mixture (A) is prepared by adding charcoal powder to ocher and masato as materials, and the mixture ( The present invention relates to a clay brick obtained by injection molding and molding A) into a certain form, and then applying clay powder, charcoal powder, and flux mixture (B) powder on the surface thereof. It is a clay brick which is blended with bricks and is beneficial to the human body and has an effect of preventing various skin diseases, and can be used for various purposes such as clay floor brick or building interior and exterior.

Clay is a fine soil particle with a diameter of 0.004mm or less, and when the rock is weathered and decomposed, it is mainly composed of silicon, aluminum and water, and a clay mineral is formed.The clay has a sintered property and heats like a rock. Due to its hardening properties, it is used for a lot of industrial purposes, and is used as a raw material for bricks, ceramics, and refractory materials.

However, when the clay brick is simply manufactured only with clay, the surface treatment of the brick is monotonous and the color is not natural because of its simple color. Therefore, it is difficult to make a surface treatment suitable for beautiful and elegant decorative and interior and exterior bricks. In addition, recently, the influence of the well-being culture has recognized the need for clay bricks that are excellent for decorative and interior and exterior, but also beneficial to the human body to solve the needs of modern people who have a great interest in health.

In order to solve the problems described above, in the present invention by mixing the clay charcoal powder in a certain ratio on the ocher and masato and then molding the clay powder and charcoal powder in the form of powder, the surface is not only elegant and beautifully expressed but also the ocher component To produce a brick with the advantages of the charcoal and the charcoal of the benefits to the beneficial components to the human body to express, as well as to provide a method of manufacturing a clay for building interiors that can help to treat and prevent various skin diseases.

The present invention to achieve the above object,

70% by weight of ocher, 10% by weight of finely pulverized charcoal and 0.1% by 1mm in a mill and 20% by weight of masato to form a mixture (S);

Injecting and molding the mixture (A), and then applying a powder of the mixture (B) consisting of 40 to 55% by weight of clay, 25 to 35% by weight of charcoal powder, and 10 to 25% by weight of flux (S2);

Applying the powder to dry the molded brick at 50 to 150 ° C. for 40 to 50 hours (S3);

After the dried brick is baked for 30 to 40 hours at a temperature of 1020 ~ 1250 ℃ gradually cooling (S4); the method of manufacturing a clay brick using a charcoal powder and clay powder made through the main configuration.

The mixture (A) is made by mixing 70% by weight of ocher, 10% by weight of charcoal and 20% by weight of masato, wherein when using less than 10% by weight of charcoal, the function of the charcoal is insignificant and the effect of the charcoal is clay brick. It can not be properly exhibited in, and when used in more than 20% by weight, the durability of the clay brick is lowered, it is preferable to use in 10 to 20% by weight.

When the ocher is used at less than 65% by weight, the binding strength of the clay brick is lowered, and when used at 70% by weight or more, since the amount of other components is relatively reduced, there is a disadvantage that the expression of useful functions such as charcoal falls. Preference is given to using at -70 wt%.

Masato has a uniformity coefficient of 7.88 and a curvature coefficient of 0.71, which is a coefficient representing an evenness of the particle size of the filtration sand used for filtration of 0.4% and 0.474 mm, and the strength of the brick is less than 20% by weight. It has a disadvantage of falling, and when used in more than 30% by weight, the strength of the brick is not used because of the lack of viscoelastic strength of the washing or ocher, it is preferable to use 20 to 30% by weight. In addition, if the drying time is rapidly dried at 40 hours or less, bricks are cracked, and if dried for more than 50 hours, productivity is decreased, so it is preferable to dry them properly for 40 to 50 hours at a temperature of 50 to 150 ° C.

In the firing, if the product is too sintered, the product is cracked, and if the temperature is lowered, the strength of the product is lowered. If the temperature is too high, the product is cracked or the manufacturing cost is increased, resulting in poor economic efficiency.

The powder of the mixture (B) is applied to the clay brick surface formed by injection and molding a mixture of the charcoal, ocher and masato as described above, wherein the mixture (B) is 40 to 55% by weight of clay powder and , Charcoal powder 25 to 35% by weight, and flux 10 to 25% by weight, the clay powder has a particle size of 0.1 ~ 1mm, the charcoal powder has a particle size of 0.1 ~ 1mm, the flux as clay, pottery, feldspar One or two selected from kaolin are used.

The configuration described above will be described in more detail with reference to the embodiment.

Example: Manufacturing Method of Clay Brick

Example 1: Mixture (A)

It is composed by mixing 10% by weight of charcoal pulverized into 0.1 mm size, 70% by weight of ocher, and 20% by weight of masato using a pulverizer.

Example 4: Mixture (B)

45 weight% of clay powder, 30 weight% of charcoal powder, and 25 weight% of flux are comprised.

Example 5: Clay Brick

After the injection molding and molding the mixture (A) as in Example 1, the mixture (B) as in Example 4 is applied.

The coated and molded bricks are dried at 50 to 150 ° C. for 40 to 50 hours, and then the dried bricks are baked at a temperature of 1020 ° C. to 1250 ° C. for 30 to 40 hours, and then gradually cooled to complete clay bricks.

Clay bricks manufactured and completed as described above can be used for various purposes such as bricks and floor bricks as decorative or building interior and exterior materials.

As discussed above, the clay brick using the charcoal powder and clay powder not only allows the beneficial ingredients to be expressed by the ocher as the main raw material, but also adds the charcoal to help prevent various skin diseases by the function of the charcoal. It is used for interior and exterior of the building, and provides aesthetics due to the unique color of clay and the subtle color of clay, which contributes to aesthetic bricks as well as to the health of modern people.
