The present invention relates to a gudeuljang and a gudeuljang manufacturing method provided by mixing/compressing scoria and loess soil, wherein scoria raw stone powder and loess powder are mixed in an appropriate weight ratio, a natural plant binder is mixed, and then compressed in a concave groove of a press mold. When the concave groove is filled with the primary filling material to a depth of 1/2 to 1/3 of the mold height, a metal mesh net is raised to form an intermediate layer. It is a technology related to Scoria Gudeuljang that has a strong bonding force and reduced weight by performing press compression after filling.

Ondol means warm stone. It is a unique heating method in Korea, and it is so closely connected with our residential culture that it is impossible to describe the residential culture in our history except for the ondol.

Ondol refers to a structure in which stones are laid on the floor of a room and a fire is made to heat the stones (gudeul) to heat the room. It was called by various names such as Gudeul, but since the 19th century, it has been settled as Ondol. When it is lit, Ondol emits a fire, a gudeuljang that receives the heat from the fire, a dogjari that prevents the heat from escaping quickly, a smoke flue, and a smoke. It is composed of a chimney, and it is recorded that there was an ondol culture from the Goguryeo period in the old Tang dynasty.

The purpose of this application is to provide a gudeuljang using a material called Scoria, which is produced by volcanic eruptions on Jeju Island. When the magma of Scoria erupts, it rises to a high temperature from 700 to 1200 degrees, and various substances ejected when it exploded. In the middle, porous volcanic rock, volcanic sand, and other volcanic ash are mixed and it refers to minerals produced in volcanic regions around the world. Depending on the content of the mineral or metal component, the color takes on various colors including reddish-brown.

In particular, scoria, which is produced only in Jeju Island, is scattered in some oreum areas and is referred to as “Jeju volcanic cone” in the Jeju dialect. It is characterized as an eco-friendly material.

Table 1 below shows the composition ratio of "Jeju Volcanic Cluster", and the content of SiO ₂ , Al ₂ O ₃ , Fe ₂ O ₃ reaches 75% and the content of organic impurities is relatively low. It is known. (Data provided by Jeju Island)

As a physical characteristic of "Jeju Volcanic Cluster", the absorption rate is high from 17% to 32% depending on the production area of Jeju Island, and the abrasion rate is 47% due to various factors such as the density of the tissue, strength, homogeneity, and excessive pores. at 67%, higher than gravel or sand, the specific gravity is light from 0.65g/cm3 to 0.65g/cm3, and the absolute dry specific gravity (inside the pores) is related to the moisture content in the pores, which is one of the main characteristics of “Jeju Volcanic Cluster”. The specific gravity after removing all the moisture contained in the pores) is 1.31 g/cm3 to 1.9 g/cm3, and the surface dry specific gravity (the specific gravity in the state where there is no water on the surface of the pores of Scoria but the inside of the pores is filled with moisture) shows a low characteristic from 1.85 g/cm 3 to 2.45 g/cm 3 .

In addition, as shown in Table 2 below, "Jeju volcanic cone" has a far-infrared emissivity of 92~93% (5~20㎛), a radiant energy of 3.74x10 ² W/m2, an ammonia deodorization rate of 84~89%, and an antibacterial property of 99.97%. As a result, it has superior characteristics than other minerals. And it has an eco-friendly function that regulates the amount of moisture around it. (Data provided by Jeju Island)

In particular, in the case of "Jeju volcanic scoria," a scoria from Jeju Island in the Republic of Korea, unlike scoria from other regions, it has a characteristic that it does not contain sulfur, so it can be said that its useful value is very high. It has superior properties and has the potential to be used as an eco-friendly and harmless material through proper processing.

In particular, in the case of "Jeju Volcanic Pine", a scoria from Jeju Island in the Republic of Korea, unlike scoria from other regions, it does not contain sulfur, so it can be said that its utility value is very high.

In other words, Jeju volcanic cluster has superior characteristics than scoria in any region of the world and has the potential to be used as an eco-friendly and harmless material through appropriate processing. In -0791053, a filter using scoria as a main material and a technology related to an air purifier using the same, and a cosmetic composition containing Jeju scoria as a main ingredient are presented in Registered Patent No. 10-0567122. The reason why it cannot find its useful value is because volcanic ash, which rose to a high temperature of 700 to 1200 degrees during the eruption of volcanic magma, does not have binding power with other materials.

Here, by using Jeju volcanic stone scoria with excellent properties, it has excellent antibacterial and antiviral effects and there is no risk of generating harmful gases. have a purpose

In addition, in order to achieve a composition to reduce the weight while securing high bonding strength while using Jeju volcanic stone scoria, which does not have binding force, as a gudeuljang, scoria raw stone powder and loess powder are mixed in a specific weight ratio, and a natural plant binder is mixed and then pressed. The purpose of providing a method of manufacturing scoria gudeuljang that forms a two-step filling structure when pressed in a mold and secures high bonding strength and strength by placing a metal mesh net on the middle position of the first and second fillers to form an intermediate layer. have

Hereinafter, the present invention will be described in more detail, and specific examples of the technical idea of the invention will be described in detail with reference to the drawings.

However, since the specific embodiments presented herein merely show one possible example that can be derived from the technical idea of the present invention, the technical scope of the present invention is not limited to the embodiments or drawings described herein.

1 shows a manufacturing process diagram of scoria gudeuljang using scoria, loess, and iron mesh mesh according to the present invention.

The present invention is to provide a gudeuljang that is used as an ondol for a building using Jeju scoria raw stone. x102 W/m2, ammonia deodorization rate of 84~89%, and antibacterial property of 99.97% range, utilizing the excellent properties that are hard to find in other minerals. Since volcanic stone made of a mixture of porous volcanic rock and volcanic sand and ash among the various materials used does not provide bonding strength, the scoria gudeuljang provided by mixing/compressing with baked ocher, a representative material that also has a far-infrared radiation function, has high bonding strength and bonding strength. As a means to secure

As a first step, the first powdering step (S10) of pulverizing and pulverizing the scoria ore is required, and the powdered scoria ore is passed through a sieve in the range of 200 to 350 mesh as a fine particle size standard and a coarse particle size specification As a result, a second screening step (S 20) of separating into a standard that has passed through a sieve in the range of 50 to 150 mesh is required. The preparation process of the third step (S 30) in which a metal mesh network is prepared for increasing the .

When the raw material is prepared as described above, the pressing process is performed. If you want to separate and apply Scoria rough stone or loess into fine and coarse particle size standards, fine particle size powder is used in the surface protrusion of the final product, Gudeuljang, so that the surface of Gudeuljang is smooth and beautiful. It is intended to be made and provided, and the coarse-grained part has a rough outer surface and is intended to provide high bonding strength with the adjacent side gudeuljang and bottom surface. Since the scria powder differentiated at a high temperature of 1200°C and the baked loess fired in a kiln maintained at 350-550°C are not easily combined, a binder is required, and the binders provided as chemical products are harmful to the human body. As a natural adhesive, a natural adhesive product that is harmless to the human body, such as glue or shellac, provides the adhesion between the Scoria powder and ocher powder.

In addition, when raw ocher mixed with scoria is used as it is, it does not provide complete bonding strength due to the foreignness with the volcanic ash, scoria raw stone. It is necessary to separate and apply the standard that passed a sieve in the range of 200 to 350 mesh as a particle size standard and a standard that passed a sieve in the range of 50 to 150 mesh as a coarse particle size standard to increase bonding strength. 7±2: Mixed in a weight ratio of 3±2, and in a state where 5 to 15% by weight of the natural plant binder of the mixture is mixed, the primary filling material is made and first placed in the concave groove of the press mold (S 40). After filling with the primary filler to a depth of 1/2 to 1/3 of the height of the concave groove of After mixing in a weight ratio of 5 to 15% by weight of the natural plant binder of the mixture, the secondary filling material is filled to a depth of 1/2 to 2/3 of the height of the concave groove of the press (S 60). It shows that after the press compression process (S 70) is performed and dried (S 80) for 3 to 4 days in an aging room maintained in the range of 40 to 70 ° C., the finished product (S 90) of Scoria Gudeuljang can be obtained.

In the manufacturing process of the present application, as described above, to separate and apply scoria rough stone or loess into fine grain size and coarse grain size standard, fine grain size powder is used in the surface protrusion of Gudeuljang in the final product to make the surface of Gudeuljang smooth and beautiful. The part made of scoria and loess is to achieve high bonding strength with the gudeuljang and bottom surface of the adjacent side with a rough outer surface. A binder is required because scria powder and baked loess fired in a kiln maintained at 350~550℃ are not easily combined. Binders provided as chemical products can cause harm to the human body. Natural adhesive products that are harmless to the human body, such as shellac, provide the adhesive strength of our Scoria powder and loess powder.

Furthermore, when a metal mesh network is interposed between the primary and secondary fillers classified by particle size and a high pressing pressure in the range of 100 to 300 tons is applied, a scoria gudeuljang that secures high bonding strength and strength can be obtained. For example, if the unit scoria Gudeuljang size is to be provided in the dimensions of width * length * height 400 mm * 400 mm * 30 mm, it is formed in the form of a concave groove with the size of width * length * height 400 mm * 400 mm * 30 mm based on the inner diameter. First, place the primary filler with a fine particle size at a height of 12 mm inside the frame, and place a metal mesh with dimensions of width * length * thickness (height) 400 mm * 400 mm * 3.5 mm on top of the primary filler. Secondary filling material of coarse particle size is placed on the top again at a height of 24 mm, compressed with a high-pressure press of 100 tons or more, aged for 5 minutes, and then taken out. With a weight of about 7.8 kg, you can get a Gudeuljang that is not too burdensome to transport.

Therefore, in this technology, scoria raw stone or loess powder separated by particle size is the primary filling material, and scoria powder and loess powder are mixed in a weight ratio of 7±2: 3±2, and a natural plant binder of 5 to 15% by weight of the mixture is added. After mixing, the pre-treatment process of first filling to a depth of 1/2 to 1/3 of the height of the concave groove of the press, and after the pre-treatment process is performed, the metal mesh net is raised to form an intermediate layer, and 50 to 150 Scoria powder and loess powder of mesh passing standard are mixed in a weight ratio of 7±2: 3±2, and after mixing 5~15% by weight of natural plant binder of the mixture, 1/2~2/ of the height of the concave groove of the press A method of manufacturing scoria gudeuljang including a process in which press compression is performed after secondary filling to a depth of 3 can be implemented.

Figure 2 shows the stacked structure of one unit gudeuljang provided by applying the technical idea of the present application. First, roasted ocher and scoria powder are pulverized and passed through a sieve in the 300 mesh range. Scoria raw stone powder and loess powder The primary filler (10) obtained by mixing in a 7:3 weight ratio and adding shellac in a ratio of 10% by weight of the mixture is placed on the bottom of the concave groove of the mold that is kept heated at about 90°C, and the primary filler (10) An iron mesh 20 with a diameter of about 2.5 mm is placed on the upper part, and Scoria rough stone powder and loess powder of coarse particle size passed through a sieve of 50 mesh on the upper part are mixed in a 7: 3 weight ratio and 10 weight of the mixture It shows that the desired Scoria Gudeuljang (100) can be obtained here by putting the secondary filling material (30) obtained by adding and mixing shellac in a % ratio and pressing it with a pressure of 200 tons.

3 shows an example of an application of the iron mesh network 20 used as an intermediate material of the Scoria Gudeuljang 100 of the present application, most of the iron mesh networks 20 are provided with the same horizontal * vertical standard, but in the present application After mixing with scoria powder, baked ocher and natural adhesive, performing the compression process with a high-pressure press in the range of 100 tons, and drying it in a maturation room maintaining the range of 40℃ to obtain the finished product As shown in Fig. 3 in the process of confirming this occurrence and researching to obtain a more complete product, the left side of the rectangular structure of the steel mesh mesh forming the rectangular structure is located on the bottom surface, and the right side is the adjacent side rectangle. A process of experimenting after obtaining a finished product by drying in a maturation room maintained at 40°C, applying a press pressure of 200 tons or more, using a steel mesh network with a continuous inclined connection surface to be located on the upper surface of the steel mesh network of the structure has confirmed the fact that it has high bonding strength and strength that is not easily broken even when trying to dismantle it with a hammer hammer.
