Description

Air drain of Wood-charcoal-different material composite for humanbody-favored building material

In general, charcoal has repair, aeration, adsorption, and heat storage properties, so it adsorbs bad smells and harmful gases, purifies air, emits far infrared rays and negative ions, prevents noise, prevents electromagnetic waves and harmful wavelengths, and improves blood circulation, metabolism, As a material to relax the mind and body, the charcoal is stored in a container several times in a container, next to a computer or a TV, or in a closet or at the corner of a living room. The method of burying in the building site has been used in ancient tombs since BC. It raises the potential in the living environment, releases the negative ions and prevents oxidation, air purification, gas adsorption, humidity control and far-infrared radiation. do. Recently, the interior of the building is a sheet of powdered charcoal embedded in a butane or nonwoven fabric that puts charcoal on a non-woven fabric under a floor or living room, and is put in the wall to induce a refreshing feeling. The method of manufacturing the charcoal plate by carbonization, namely wood ceramic method (Japanese Patent 特 開平 4-164806), has been developed to solve the problems such as splitting and torsion caused by general charcoal carbonization. It also takes a lot of defects (60-100% of fiberboard), so

(2002 Korean Patent Application: 10-2002-0003999) developed a clay-wood ceramic manufacturing process, a porous carbon material, and reduced the process to two stages. However, to be used for construction, whether it is wood ceramic or clay wood ceramic, it has to be carbonized with a large area plate. The long-term continuous large area carbonization device requires enormous investment facilities and precision. Therefore, VOCs according to formarin and volatile solvents can be used while appropriately processing the particle size of charcoal, chipped carbide, or commercially available activated carbon produced using existing carbonization furnaces or continuous carbonization furnaces. The charcoal board, a porous carbon material manufactured with good foaming and heat pressure without problems, is made of a functional board and a composite board made of porous carbon material as a human-friendly living environment material to have sufficient strength and surface property for construction as a building material. The applicant has filed (2002 Korean Patent Application No. 10-2003 -0048137) In the developed countries such as Japan, since the Building Standard Act amended from July 2003 due to the Sick House issue, the E ₀ type of formalin interior finishing material close to zero formalin The housing industry and the timber industry are responding quickly to environmental problems. According to the domestic indoor environmental pollution VOC concentration in 2000, the indoor pollution of domestic buildings more than 3 months after construction was 600ppb due to paper wallpaper (3833㎍ / ㎡h), various paints, and formarin adhesives used for manufacturing wood materials. As a building material, charcoal-based products purify these volatile organic compounds, remove bad odors, and have repair, aeration, adsorption, and heat storage properties. It is the best human-friendly material for building materials if it expresses the properties of charcoal as it prevents noise, electromagnetic waves and harmful wavelengths, but it has only functionality to preserve the functionality of charcoal products as interior materials in domestic construction based on concrete and cement. Since the surface color of charcoal board is black, its use as a residential environment material is less, There is a need for composite materials for the purpose of overlaying thin wood veneers filed by the applicant or compounding perforated plywood to improve the surface properties so that they can be used as interior materials for construction. And it is difficult to secure the decorative properties, which requires the technology of new composite materials to add decorative properties while utilizing more functionality.

Therefore, the present invention is a composite structure, the surface of the wood and wood materials to arrange the natural beauty of the wood and the advantages of the wood and the charcoal board (activated carbon board) or charcoal filling box on the back of the composite structure so that the functionality of the charcoal does not fall at all The present invention relates to a method for determining an appropriate ratio of air inlets related to the air inlet pore structure. In order to manufacture functional charcoal boards and to decorate the surface of black charcoal boards, it is limited use to overlay wood veneers or composite perforated plywood as building interior materials. Therefore, the strength of wood as wood and wood materials in front of composite materials It is manufactured by combining the charcoal board on the back or by combining the box with charcoal powder or activated carbon particles (the material is metal, plastic, wood material), and the wood and wood materials and charcoal and activated carbon board or charcoal filling. The joint method between the box and the composite structure uses the slider type, siding type, and louver type to characterize the charcoal located on the back of the composite structure, so that it can act as a human-friendly residential environment material. It is a technical task of the present invention to determine the proper ratio of the related air inlet.

In order to achieve the above object, the present invention first uses a wood and wood material as a surface material and the back side as a charcoal board (or activated carbon board) to be used as a wall material or a living environment material, but the slider type in the joint between composite materials In order to activate the function of the charcoal board located at the back, it has a proper air gap in the louver and siding type. Second, use wood and wood materials as surface materials, and a box filled with charcoal powder or activated charcoal powder instead of charcoal board on the back (photo 1, material is metal, plastic, wood materials) to be used as wall material or residential environment material. However, it has been developed to activate the function of the charcoal on the back side by providing a suitable air gap in the slider type, siding type, and louver type in the joint between composite materials. Therefore, whether the air inlet area ratio is related to charcoal board or charcoal particle filling box area related to air inlet pore structure in the joint between wood and wood material and composite material as surface material It will be a key to whether or not to activate the present invention through the following examples.

Example 1 Appropriate ratio of air inlet with respect to air inlet pore structure to show the charcoal properties of charcoal board on the back of wood and wood materials and charcoal board composite

The charcoal for the production of porous carbon material charcoal board was made from Wonju oyster oak white charcoal and coconut shell made from imported carbon (coal 6-18 mesh) as raw material. According to the material manufacturing method (2002 Korean Patent Application: 10-2003-0048137), the white charcoal board was manufactured in a mixed type that is easy to produce and effective. The surface material is made of wood and wooden materials. Composite of white charcoal board and activated charcoal board can be used to estimate the properties of composite materials according to the type and thickness of constituent materials, which are obvious to those with ordinary knowledge in this field. Joint between composite materials to show the charcoal properties of charcoal boards formed on the back of wood and wood materials showing the decorativeness of phosphorus surface In the slider type (picture 1), siding type (picture 2), and louver type (picture 3), the air inlet pore structure (air inlet area) is placed to activate the function of the charcoal board on the rear side to activate the function of the charcoal board on the back side. To explain how the ratio of the inlet area of the inflow gap saves the functionality of charcoal, see Table 1. According to the inlet area ratio of the air inlet pore structure of the seam between the composite materials, In terms of the adsorption performance of ethylene gas, if the inlet area ratio of the air inlet pore structure to the area of the white board is 20%, after 3 hours, the white board of the white board is completely exposed to the front surface of the room. It absorbed about 55% of the gas and the gas residual amount was about 45%, and the air inlet area ratio was 10%. All of the white charcoal boards showed the same effect as 100% exposed to the front surface of the interior wall.If the inlet area ratio of the air inlet gap was 5%, the white charcoal boards located at the back of the interior wall were 100 on the interior front surface after 24 hours. Activated carbon board has much higher gas adsorption function than white carbon board, so the indoor wall is 5% if the inlet area ratio of air inlet pore structure is 5% of the area of activated carbon board located behind the interior wall within 3 hours. The activated carbon board on the back had the same effect as 100% of the front surface of the room. Even though the inlet area ratio of the air inlet pore structure was reduced to 2.5%, the activated carbon board on the back of the interior wall adsorbed about 90% of the gas within 12 hours, showing the same effect as 100% of the activated carbon board on the front surface of the room. . Therefore, if the inlet area ratio of air inlet pore structure to charcoal board area is 5% in the joint between the composite materials, slider board, siding type and louver type, the activated carbon board on the back of the composite material is 12 hours in 24 hours and the white board is 24 hours. As a functional material for residential use, the surface is made of charcoal board on the back while utilizing the natural beauty of wood and wood materials and the merits of wood as the charcoal board is exposed to 100% of indoor front surface. Could.

Example 2 Appropriate ratio of air inlet related to air inlet pore structure for showing charcoal properties of wood and wood materials, charcoal particles and activated carbon particle-filled composite structure

The charcoal for the composite structure of wood and wood materials and a box filled with charcoal particles was imported activated carbon (coal 6-18 mesh) made from Wonju oyster oak white coal and coconut shell. In Example 1, wood and wood materials are placed in a surface direction toward the interior, and a charcoal board is placed in the opposite direction, whereas in Example 2, a charcoal particle is placed in a box instead of a charcoal board in a box. It can be said that it is different from the composite structure in which it does not come out but drills a hole to show a charcoal function or arranges a char and activated carbon particle filling phase on the wall. In addition, it can replace the outer plate of the box lid with a net and has the advantage of exchanging charcoal particles if necessary. As shown in the picture 1, the material of the charcoal particle box may be made of aluminum or stainless steel, or made of wood, such as plastic or plywood. Composite material manufacturing can calculate the properties according to the thickness and the properties according to the type of constituent material and is omitted here because it is well known to those skilled in the art. A feature of the present invention is the use of wood and wood materials on the surface to take advantage of the natural beauty of wood and the advantages of wood, and to show the properties of charcoal from the charcoal particle packed phase formed on the back of wood and wood materials. The jointing method between the composite structures for characterizing charcoal from charcoal particle packed bed formed on the back of wood and wood materials adopts slider type, siding type and louver type as in Example 1. We will focus on exploring how the ratio of the inlet area of the air inlet pore structure to the char particle filling area to activate the charcoal particle function to activate the charcoal on the back side.

As shown in Table 2, when the air inlet area ratio of the air inlet pore structure to the area of the white charcoal particle charge is 20%, after 3 hours, the amount of gas adsorption of the white charcoal particle box is 100% exposed to the inner surface of the room. It dropped from 16 ppm to 1.4 ppm level. When the inlet area ratio was 10%, the same effect as 100% of the white charcoal filling box was exposed to the inner surface of the room after 6 hours, and when the air inlet area ratio was 2.5%, 12 Over time, the gas concentration dropped from 15.31ppm to 1.3ppm to 1 / 11.8 level, showing the same effect as 100% of the white charcoal particle box was exposed to the inner surface of the room. Activated charcoal particle charging box has much higher gas adsorption function than white charcoal particle charging box, so it can be seen that it drops to 1 ppm level at 15 ppm concentration in 6 hours. After 12 hours, when the air inlet area ratio of the air inlet pore structure is 2.5%, the gas concentration drops to 1/20 level from 15.31 ppm to 0.62-0.75 ppm and the activated carbon particle filling box is the same as 100% exposed to the inner surface of the room. Effect. If the air conditioner or fan is forced to circulate in the room, the effect will be much faster. In other words, when the concentration of HCHO in the air is generally 1 ppm, it is very high, but even if the air flow in the room does not move within 12 hours, the safe level is 0.08 ppm for charcoal and 0.05 ppm for activated charcoal. Therefore, the jointing method between the composite structures is slider type, siding type, louver type, and the time is doubled (24 hours), and the air inlet is also doubled (5%), which is 1/19 for white coal and 1/30 for activated carbon. The level of gas was lowered to the level where the function of charcoal particles located on the back of the composite structure was shown to be sufficient. The joint method is described in detail as follows. In the slider type (picture 1), the air inlet area ratio with respect to the total area of charcoal filling was 2.5-5% (plan view). For example, when the area of a charcoal particle filling box is 20㎡ (2m in height * 10m in length), it becomes 9 inlets when combined with 10 slides of 1.2m length, and the air inlet area is 0.5-1㎡. . Inlet area per slide (height 2m * thickness direction 0.0275m-0.055m) is appropriate. The siding type (picture 2) is in the form of a square channel side, which makes the air inlet invisible from the front side and makes a gap of 2.5-5% of the air inlet per siding area on the siding itself. Therefore, connecting another Square Channel Side to one Square Channel Side automatically creates a 2.5-5% air inlet in the form of a square (Photo 2. Front). The louver type (photo 3) maximizes the angle of attachment of the louvers to maximize the air inlet area ratio (barrel attachment spacing area) to the total area of the charcoal particle charging box located on the back.

Example 3 Far Infrared Emissivity of Wood and Charcoal

Wood and charcoal are materials that emit far infrared rays at more than 90% at room temperature as shown in Table 3, and their lifespan is very long as the material life. Since the treatment of diseases using far infrared rays in 1976, commercial medical devices using far infrared rays have been produced and used. It has been shown to enhance metabolism of the family, eliminate blood disorders, and increase the regenerative capacity of tissues. About 70% of the human body is composed of water. The wavelength band of the water molecule is 10㎛ and the wavelength band emitted by the human body is 3-50㎛, which emits 46% of the wavelength of 8-14㎛, so I think this wavelength band is the wavelength band which the human body likes to accept. When far-infrared radiation is emitted to the human body, water molecules are activated and blood circulation is promoted. Therefore, far infrared rays are radiated to the water and protein molecules that make up the cells in the human body, and the cells warm rapidly through vibrations that gently shake the cells 2,000 times per minute, promoting blood circulation and activating cellular tissues. It also promotes the assimilation of plants, which is why far-infrared rays are also called growth rays. Therefore, the composite material of wood and charcoal emits more than 90% of far-infrared rays at room temperature.
