Description

  The present invention is a method of manufacturing a composite structure of wood and woody material and charcoal and activated carbon board or porous charcoal box, which is a slider type, a louver type. The siding type (Siding Model) is used to sufficiently move the charcoal characteristics arranged on the back surface according to the inlet area of the air inlet gap structure, and the inlet area ratio of the air inlet gap structure is 2. It relates to a method of 5 to 5%.

  In general, charcoal has repair, ventilation, adsorption, and heat storage properties, so it absorbs bad odors and harmful gases, radiates far-infrared rays and anions as well as purifies air, prevents noise, prevents electromagnetic waves and harmful wavelengths. As a material that blocks blood circulation, metabolism, and physical and mental stability, the charcoal lump is put in a container in the container and placed next to the computer or TV, in the chest, or in the corner of the room. , Not aesthetically pleasing.

  The method of burying coal in Tsukiji is a method that has been used in ancient tombs in BC and raises the potential to the residential environment to release anions, which is optimal for materials and the human body with oxidation prevention, air purification, gas adsorption, humidity adjustment, far infrared emission, etc. An environment is created. Recently, in the case of the interior of a building, a sheet made of non-woven bag with charcoal powder is placed under the floor or living room, and the sheet is guided into a refreshing feeling.

  Carbon plate manufacturing by carbonization, that is, a wood ceramics method (Japanese Patent Laid-Open No. 4-164806) discloses a method for solving problems such as splitting and twisting that occur during carbonization of general charcoal. This product has a complicated process including four stages, and has a drawback that a large amount of phenolic resin is consumed (60 to 100% of the fiberboard).

  The 2002 Korean Patent Application (10-2002-0003999), which improved the above-mentioned problems, developed a process for producing a porous carbon material clay / wood ceramics and reduced the process to two stages. Has been started.

  However, if wood ceramics or clay wood ceramics are to be used for construction, they must be carbonized into large-area plates, so long-term continuous large-area carbonization equipment requires a great deal of investment equipment and precision.

  Therefore, charcoal produced by using an existing carbonization furnace or continuous carbonization furnace, chip-like carbide, or commercially available activated carbon particles are appropriately processed and used, and the effect of the charcoal is influenced by the adhesive. Charcoal board, which is a porous carbon material manufactured with good forming and heat pressure without VOC (volatile organic compound) problems caused by formalin and volatile solvents, can be applied as a building material. The applicant has applied for the manufacture of a porous carbon material functional board composite material (2002 Korean patent application: 10-2003-0048137) as a human-friendly housing environment material having sufficient strength and surface properties.

  In developed countries such as Japan, the Building Standards Act was revised in July 2003 due to the Sick House issue, so the EO type (particle board) non-formalin interior finishing material close to zero formalin was used, and the housing industry and wood. The industry is responding to quick environmental problems.

According to the Ministry of the Environment, indoor environmental pollution VOC (Volatile Organic Compound) concentration in Korea in 2000 was 3 months after the new construction with paper wallpaper (3833μg / m ² h), various paints, formalin adhesives used for the production of wood materials, etc. It was clarified that the indoor pollution of the domestic building becomes 600 ppb, which is more than about 8 times the standard value.

  Therefore, products that use charcoal as a building material purify such volatile organic compounds to remove bad odors, and have repair, ventilation, adsorption, and heat storage properties, so of course not only air purification but also far infrared rays and anions If the characteristics of charcoal that radiates the noise to prevent noise, block electromagnetic waves and harmful wavelengths are expressed as they are, it will be the best human-friendly material as a building material.

  However, in order to take advantage of the functionality of charcoal products as interior materials in domestic buildings, mainly concrete and cement, the surface color of the charcoal board is black because of the functionality alone, so the use as a residential environmental material is reduced. A composite material is needed.

  Overlaying thin wooden panels already filed by the present applicant or combining perforated plywood to improve the surface quality so that it can be used as a building interior material, this alone is a requirement of various consumers It is difficult to ensure the natural beauty and decorativeness of some natural wood. Therefore, a new composite material technology that adds decorativeness while using more functionality is required.

  The present invention has been devised in order to satisfy the requirements posed by solving the above problems. An object of the present invention is to arrange a charcoal board (activated carbon board) or a charcoal-filled box on the back surface by arranging wood and woody material on the surface as a composite structure, taking advantage of the natural beauty of wood and the advantages of wood. It is to provide a method for determining the proper ratio of the air inlet associated with the composite air inlet gap structure so that the charcoal function is moved by the inlet of the air inlet gap structure.

  In addition, another object of the present invention is to build a functional charcoal board that has already been filed and to decorate the surface of black charcoal board, by overlaying wood cut boards or combining perforated plywood as a building interior material. Since the use is limited, the composite material has a porous material filled with charcoal powder or activated carbon particles on the back, using charcoal board on the back, utilizing the strength and function of wood as wood and woody material on the other side of the composite material It is manufactured by compositing with the structure of metal box (material is metal, plastic, wood material), but it is slider type, siding type by connecting method between the composite structure of wood and wood material and charcoal and activated carbon board or charcoal filled box The louver method is used to move the properties of charcoal located on the back of the composite structure to the front so that it can be used as a human-friendly living environment material. To provide a method for determining the a ratio.

  In order to achieve the above-mentioned object, the present invention uses a wood and a wood material as a wall material or a residential environment material by combining them with a surface material and a back surface with a charcoal board (or activated carbon board). The connection between the sliders, louvers, and sidings has been developed so that an appropriate air circulation gap can be configured and the functions of the charcoal board on the back can be activated.

  Also, a porous box with wood and wood material as the surface material and filled with charcoal powder or activated carbon powder instead of charcoal board on the back surface (porous porosity 39 so that activated carbon powder or charcoal powder does not leak) %: In the example, metal mesh, etc. Table 1, materials are metal, plastic, wood material) and used as wall material or residential environment material, but the connection between composite materials is slider type, siding type It has been developed so that the function of the charcoal on the back side can be activated by configuring a suitable air circulation gap with a louver type.

  Therefore, the ratio of the air inlet area to the area of the charcoal board or charcoal particle filling box related to the air inflow gap structure between the wood and the wood material which is the surface material and the composite material is the charcoal board or charcoal particle on the back surface. Therefore, the present invention will be described below through examples.

[Example 1]
Porous carbon material charcoal is used in determining the appropriate ratio of air inlets associated with air inlet void structure to move charcoal properties of charcoal board located on the backside of wood and wood material and charcoal board composites to the front. As a charcoal for board production, Oriental Oak from Wonju, Gangwon Province (a deciduous tree of the beech family Quercus genus, scientific name is Quercus variabilis) imported charcoal (fine charcoal) and imported coconut fruit skin Activated carbon (particle size 6-18 mesh) was used. By the method of manufacturing porous carbon material functional board and charcoal board composite material (2002 Korean patent application: 10-2003-0048137) filed by the present applicant, it is a mixed charcoal board that is easy to manufacture and effective. Manufactured to produce a composite material.
The surface material is made of wood and wood material, and the back surface is made by combining fine charcoal charcoal board and activated carbon board, so that the properties of the composite material production can be estimated by the type and thickness of the constituent materials. Since it is obvious to those skilled in the art, a composite material is used here to show the charcoal properties of the charcoal board constructed on the back of the wood and wood material, which is a feature of the present invention for the sake of brevity. The connection between the sliders (FIG. 1), siding (FIG. 2), and louver (FIG. 3) constitutes an air inflow gap structure (air inlet area) to activate the function of the charcoal board on the back surface. Thus, a focus will be given to clarify how the ratio of the inlet area of the air inlet gap to the total area of the charcoal board takes advantage of the charcoal functionality.

  As shown in Fig. 1, when examining the ethylene gas adsorption performance of the charcoal board on the back of the composite material according to the inlet area ratio of the air inlet gap structure in the connection between the composite materials, the fine charcoal board area versus the inlet area of the air inlet gap structure If the ratio of 20% is 3%, after 3 hours, all the fine charcoal boards located on the back of the indoor wall are exposed to 100% on the front surface of the room, and about 55% of the gas is absorbed. As a result, the residual gas amount was about 45%.

  When the air inlet area ratio was 10%, after 6 hours, the same effect was obtained that the fine charcoal board on the back side of the composite material located on the back surface of the indoor wall was 100% exposed on the front surface of the indoor wall. . When the inlet area ratio of the air inflow gap was 5%, the same effect was obtained that after 24 hours, 100% of the fine charcoal board located on the back surface of the indoor wall was exposed on the front surface of the indoor surface.

  The activated carbon board has a higher gas adsorption function than the fine charcoal board, and when the ratio of the area of the activated carbon board located on the back of the indoor wall to the inlet area of the air inflow gap structure is 5%, the activated carbon board located on the back of the indoor wall is Within 3 hours, the same effect as 100% exposure on the front surface of the room was obtained.

  Even if the inlet area ratio of the air inflow gap structure is reduced to 2.5%, the activated carbon board located on the back of the indoor wall adsorbs about 90% of the gas within 12 hours. It showed the same effect as the board was 100% exposed.

Therefore, when the connection between the composite materials is a slider type, a siding type, and a louver type, and the inlet area ratio of the air inflow gap structure to the charcoal board area is 5%, the activated carbon board located on the back surface of the composite material is 12 It was found that the fine charcoal board exhibited an adsorption function equivalent to the fact that the charcoal board was exposed 100% on the front surface of the room within 24 hours. Therefore, as a functional material for residential use, the surface was able to take advantage of the charcoal on the back side while taking advantage of the natural beauty of wood and wood materials and the advantages of wood.

* 1: Ratio of composite material backside charcoal board area to inlet area of air inflow gap structure
* 2: Ethylene gas blank concentration change in the measurement vessel, ppm unit
* 3: Charcoal board (size, 5cm x 5cm x 1cm) was placed in the measurement container and treated so that the gas was adsorbed only on the surface. The fact that the measured value is small is that a large amount of gas was adsorbed.

[Example 2]
Appropriate ratio of air inlet to air inflow gap structure to reveal charcoal properties of wood and wood material and charcoal particle and activated carbon particle filler composite structure.

  Charcoal for the composite structure of wood and wood materials and boxes filled with charcoal particles is a fine charcoal of oriental oak (Waconaceae Quercus variabilis) fine charcoal from Wonju, Gangwon-do, and coconut fruit Imported activated carbon (particle size 6-18 mesh) made from leather was used.

  The difference from Example 1 in which wood and wood material are arranged in the surface direction facing the room and charcoal board is arranged in the opposite direction is that in Example 2, charcoal particles are put in a box instead of charcoal board. In order to prevent the charcoal particles from coming out of the outer plate that hits the lid of the box, the charcoal and activated carbon particle fillers are arranged on the opposite wall in the room while arranging the fine pores to show the charcoal function This is a composite structure.

  Moreover, there is an advantage that charcoal particles can be exchanged when necessary by replacing the outer plate of the box lid with a net. As shown in Table 1, the material of the charcoal particle filling box can be made of aluminum or stainless steel, plastic, or wood material such as plywood. Composite material manufacturing can be calculated by thickness and properties depending on the type of component, and is omitted here because it is a method well known to those having ordinary knowledge in the field.

  A feature of the present invention is to use wood and wood materials on the surface to take advantage of the natural beauty of wood and the advantages of wood to reveal the charcoal properties from the charcoal particle packing constructed on the back of the wood and wood material. It is.

  In order to show the properties of charcoal from the charcoal particle packing formed on the back surface of the wood and wood material, the method of connecting the composite structures is the same as in Example 1, adopting the slider type, siding type, and louver type. How to use the charcoal particle functionality by the ratio of the inlet area of the air inflow gap structure to the charcoal particle filling area so as to activate the charcoal function on the back side at an appropriate interval (air circulation port) To focus on elucidating

  As shown in Table 2, when the ratio of the fine charcoal particle packing area to the air inlet area of the air inflow gap structure is 20%, the fine charcoal particle filling box is 100% exposed on the inner surface of the room after 3 hours. As a result, the same gas adsorption amount as shown in FIG.

  When the air inlet area ratio was 10%, after 6 hours, the same effect was obtained that 100% of the fine charcoal particle packed box was exposed on the inner surface of the room. When the ratio of the air inlet area of the air inflow gap structure is 2.5%, the gas concentration drops to the level of 1 / 11.8 from 15.31ppm to 1.3ppm after 12 hours, and the fine charcoal particle packed box Had the same effect as being 100% exposed on the inner surface of the room.

  The activated carbon particle packed box has a higher gas adsorption function than the fine charcoal particle packed box, and it can be seen that the concentration drops from 15 ppm to 1 ppm in 6 hours. When the ratio of the air inlet area of the air inlet gap structure is 2.5%, the gas concentration drops from 15.31 ppm to 0.62 to 0.75 ppm to 1/20 level after 12 hours, and activated carbon particles The effect is the same as if the filled box was 100% exposed on the inner surface of the room.

  If air is forcibly circulated by an indoor air conditioner or fan, the effect is improved at a speed faster than the time exemplified above. That is, the above results are generally very high if the HCHO concentration is 1 ppm in the air, but even if the air flow in the room does not move within 12 hours, the fine charcoal has a safe level of 0.08 ppm. In this case, it is reduced to 0.05 ppm.

  Therefore, if the connection method between the composite structures is the slider type, siding type, and louver type, the time is doubled (24 hours), and the air inlet is doubled (5%). / 19, in the case of activated carbon, the gas concentration is reduced to 1/30 level and the function of the charcoal particles located on the back of the composite structure can be fully exerted, so the ratio of the inlet area of the air inflow gap structure to the charcoal filling area is 2. Even 5 to 5% is appropriate.

Next, the connection method will be specifically described. In the slider type (FIG. 1), the ratio of the air inlet area to the entire charcoal filling area was set to 2.5 to 5% (plan view). For example, when the area of the charcoal particle filling box is 20 m ² (height 2 m × length 10 m), when combining with 10 slides having a length of 1.2 m, the air inlet becomes 9 inlets. The total area is 0.5-1 m ² .

It is appropriate if the inlet area per slide (height 2 m × thickness direction 0.0275 m to 0.055 m) is used. The siding type (Fig. 2) is in the form of a square channel side, and the air inlet is not visible from the front, while the siding itself has a 2.5-5% air inlet per siding area. make. Therefore, if another square channel side is connected to one square channel side, an air inlet of 2.5 to 5% can be automatically configured in a quadrangular form (Table 2. Front).

  The louver type (FIG. 3) is a method that maximizes the adhesion angle of the louver so that the air inlet area ratio (louver adhesion interval area) to the entire area of the charcoal particle filling box located on the back surface is 2.5 to 5%. To.

  Table 2. Ethylene gas adsorption performance of charcoal particle packing located on the back side of the composite structure based on the inlet area ratio of the air flow gap structure of the composite structure

* 1: Ratio of inlet area of air inflow gap structure to charcoal particle filler area (%)
* 2: Ethylene gas blank concentration change in the measurement container, ppm unit
* 3: Charcoal particle box (surface area: 25 cm ² ) was placed in the measurement container, and the lid of the box was made of a net with 39% voids to reveal the charcoal function. The gas is adsorbed over time, and the residual concentration of ethylene gas in the container decreases. ppm units. The smaller the measured value, the more gas was adsorbed.

[Example 3]
Far-infrared emissivity of wood and charcoal As shown in Table 3, wood and charcoal emit 90% of far-infrared rays at room temperature, and their lifetime is as long as the lifetime of the material.

  Since the treatment of diseases using far infrared rays in 1976, commercial medical devices using far infrared rays have been produced and used. The effects of far-infrared rays on the human body are the increase in the temperature of the subcutaneous layer, the expansion of fine blood, the promotion of blood circulation, the strengthening of metabolism between the blood, the human body and other organizations, the elimination of blood disorders, the increase in the ability to regenerate the organization, At the same time, it is known to have abnormal excitation suppression of sensory nerves and function adjustment of autonomic nerves.

  About 70% of the human body is composed of water. The wavelength band of water molecules is 10 μm, and the wavelength band emitted by the human body is 3 to 50 μm, of which 46% radiates at a wavelength of 8 to 14 μm. This wavelength band is a wavelength band that is easy for the human body to accept, and even if it is weak at room temperature, if far infrared rays are emitted to the human body, water molecules are activated and blood circulation is improved.

  Therefore, far-infrared rays are radiated to the water and protein molecules that make up human body cells, and the cells warm up rapidly through vibrations that shake the cells minutely 2000 times per minute, promoting blood circulation and activating cellular tissues. This makes it more vigorous for life and also promotes the assimilation of plants, so far-infrared rays are also called growth rays. Therefore, the composite material of wood and charcoal emits 90% or more of far infrared rays at room temperature, so it can be said that it is the best material for residential environment.

  From the above description, the present invention will be clear to those having ordinary knowledge in this field, and the above-described embodiments are for explaining the present invention and are not limited to the embodiments.

  As described above, residential environmental materials have developed mainly in terms of durability and strength. Especially in South Korea where limestone is rich, mainly cement buildings have various wallpaper, paint and VOC (volatile organic compound) discharge materials inside. Therefore, in order to solve the Sick House problem, the nature of charcoal (dehumidification, repair, ventilation, adsorption, heat storage, and the air purification action that absorbs odors and harmful gases is of course far infrared and anion. Must be studied to effectively utilize the material that prevents blood stuttering, blocks electromagnetic waves and harmful wavelengths, and provides blood circulation, metabolism, and physical and mental stability.

  Therefore, since the surface of the charcoal board utilizing the characteristics of charcoal is black because the surface of the charcoal board is used in a residential environment, the aesthetic decoration effect is reduced. Between the composite structure of wood and wood material and charcoal and activated carbon board or charcoal filled box so that charcoal board (activated charcoal board) or charcoal filled box is placed on the back using natural beauty and advantages The connection method uses slider, siding, and louver methods to provide the proper ratio of air inlets to the air inlet gap structure to reveal the charcoal properties of wood and wood materials and charcoal and activated carbon filler composite structures. When used in a residential environment, it can be used as a human-friendly building interior material for wall materials, ceiling materials, etc., or it can be used as a storage for museums and packaging materials for food and fruits. It is the can.
