Description

本発明は、揮発性有機物質(以下VOCと言う)及び臭気の吸着・分解・消臭が効率良く永続的に発揮されるように作成され且つ滅却時に有害成分を発現させない構成物で構成された建築物室内の空気清浄機能を有するシート状物とその施工に関するものである。   The present invention is composed of a volatile organic substance (hereinafter referred to as VOC) and a composition which is produced so that adsorption / decomposition / deodorization of odors can be efficiently and permanently performed and does not express harmful components upon destruction. The present invention relates to a sheet-like object having an air cleaning function in a building room and its construction.

近年住宅の壁面或いは天井面に様々な機能が付与されるようになっている。空間を仕切る見た目に美しいといった従来からの機能の他に、(1)生活空間が健康増進に役立ち、(2)壁面自体から有害なVOCを発生しないのみならず室内の建材・住宅機器から放散されるVOC或いは人やペット諸動物が生活することにより放散される臭気を吸着分解する機能、(3)抗菌・防カビ性能を有すること、(4)湿気の調整が出来ること、(5)最終滅却処分時にダイオキシン等の環境破壊成分が発生したり残存したりしないこと等が要求されるような状況である。   In recent years, various functions have been added to the wall surface or ceiling surface of a house. In addition to the traditional function of partitioning the space, (1) the living space is useful for health promotion, and (2) it does not generate harmful VOCs from the wall itself, but is also emitted from indoor building materials and housing equipment. VOC or the ability to absorb and decompose odors emitted by living humans and pet animals, (3) Antibacterial and antifungal performance, (4) Moisture adjustment, (5) Final destruction It is a situation where environmental destruction components such as dioxins are not generated or remain at the time of disposal.

近時、竹炭の効用がVOCの消臭・分解・抗菌等の機能を有することが実証され、竹炭を利用してそれから導き出される白色の生成物も開発されている。更にこれらの生成物を粉末にして塗料化する技術も公開されている。上市されている塗料も多々あるが総じてこれらの塗料は現場でロール・刷毛・スプレー等で塗装するため現場養生と塗装工数が2〜3回となり乾燥等を含めると工事期間が2〜3日掛かり、その間その部屋は使用出来なくなる。また塗装作業があるため竹炭の持つ機能を一定以上に発揮させるためには塗料使用料を多めに使用することとなる。特にリフォーム現場で使用する場合には元々の壁の色が多岐に渡るため一定の色を確保するためにも塗料の使用量が多くなる傾向にある。また素材の風合い或いは絵柄の付与が困難であり単に塗装だけに依存し意匠性はあまり考慮されていない。空気清浄の機能は確保出来るが現場施工のため手作業に時間とコストがかかりより簡便な方法が望まれている。   Recently, the effectiveness of bamboo charcoal has been demonstrated to have functions such as deodorization, decomposition, and antibacterial of VOC, and white products derived from bamboo charcoal have been developed. Furthermore, a technology for converting these products into powders is also disclosed. Although there are many paints on the market, these paints are generally applied on-site with rolls, brushes, sprays, etc., so the on-site curing and coating man-hours are 2-3 times. During that time, the room becomes unusable. In addition, since there is a painting work, a large amount of paint usage fee is used in order to make bamboo charcoal function more than a certain level. In particular, when used at a renovation site, the original wall color is diversified, and the amount of paint used tends to increase in order to ensure a certain color. Moreover, it is difficult to give the texture or pattern of the material, and it depends only on the painting, and the design is not considered much. Although the function of air cleaning can be secured, it is time-consuming and costly for manual work because of construction on site, and a simpler method is desired.

主な先行技術は下記の通りであるが、塗料化する技術が主体であり、これらの塗料を効率よく建築物に利用する具体的手段についての記載は見あたらない。

The main prior art is as follows, but the technology for converting to paint is the main, and there is no description of specific means for efficiently using these paints for buildings.

竹炭を利用した塗料を建築現場或いはリフォーム現場で塗装するためには塗装する場所以外の場所を汚さないようにするために現場養生が必要となる。また塗装する箇所は平滑面とは限らず空気清浄機能を確保するために手作業で塗装するので塗料が多めに使用される。この種の水性塗料は一度に多く塗装すると乾燥時にクラックを生ずる。目安として1回に塗る量は200g/m以下となる。従って2回〜3回の塗工回数が必要となり養生〜塗装〜乾燥までで概ね2〜3回必要となる。模様を付けたりすることは困難で非常にコストが掛かる。 In order to paint a paint using bamboo charcoal at a construction site or a renovation site, on-site curing is required so as not to contaminate a place other than the place to be painted. Also, the painted part is not limited to a smooth surface, and it is manually applied to ensure an air cleaning function, so a large amount of paint is used. If this type of water-based paint is applied many times at once, it will crack when dried. As a guide, the amount applied at one time is 200 g / m 2 or less. Accordingly, two to three coatings are required, and approximately 2-3 times are required from curing to painting to drying. It is difficult and very expensive to apply patterns.

別の技術として機能性壁紙として塩ビペースト中に酸化チタンを練りこんだもの或いは特定有機物質と反応して分解する金属塩・窒素化合物を練りこんだ機能性壁紙があるがそれらは効果が限定的であり焼却時にダイオキシンを発生させるなど地球環境に多大な負荷を与えるものであった。これらの課題を解決するために地球環境にやさしい材料であって意匠性が高くVOC/悪臭成分を効率良く永続的に吸収・分解する室内空間を安価に提供する技術が求められる。   As another technology, there is a functional wallpaper in which a titanium paste is kneaded into a vinyl chloride paste or a functional wallpaper in which a metal salt / nitrogen compound that decomposes by reacting with a specific organic substance is kneaded. It has a great impact on the global environment, such as generating dioxins during incineration. In order to solve these problems, there is a need for a technology that is inexpensive to provide an indoor space that is a material friendly to the global environment, has high design properties, and efficiently and permanently absorbs and decomposes VOC / bad odor components.

竹炭の粉末及び粘土を混練し焼成して得られる白色の多孔性焼成物を粉砕して塗料中に混合し、揮発性有機物質(VOC)及び臭気成分を吸着分解する機能を有する塗料と成し、該塗料をナイフコーターなどの塗装機を用いて工場で塗装する。塗装する基布は通気性を有する繊維質の可撓性シートが好ましく、その少なくとも片側面上に前記塗料をほぼ均等に塗布し乾燥させて揮発性有機物質(VOC)及び臭気成分を吸着分解する層を形成したシート状物を得る。前記可撓性シートは通気性があるため該シートの裏面側にも前記塗料を塗布して吸着分解層を形成すればより効率の高いシート状物を提供できる。上記のシート状物は長尺に加工し巻き取ってロール状に保管するとよい。施工現場では該シート状物の裏面に接着剤を塗布し壁或いは天井など建築物の躯体に貼り付ける事によって前記VOCの吸着及び/又は分解と消臭、更には抗菌機能を有する意匠性に富んだ空間が得られる。   A white porous fired product obtained by kneading and firing bamboo charcoal powder and clay is pulverized and mixed in the paint to form a paint having a function of adsorbing and decomposing volatile organic substances (VOC) and odor components. The paint is applied at the factory using a coating machine such as a knife coater. The base fabric to be coated is preferably a fibrous flexible sheet having air permeability, and the paint is applied almost evenly on at least one side thereof and dried to adsorb and decompose volatile organic substances (VOC) and odor components. A sheet-like material having a layer formed thereon is obtained. Since the flexible sheet has air permeability, a more efficient sheet-like material can be provided by applying the paint to the back side of the sheet to form an adsorption / decomposition layer. The sheet-like material may be processed into a long shape, wound and stored in a roll shape. At the construction site, the VOC is adsorbed and / or decomposed and deodorized by applying an adhesive to the back of the sheet-like material and affixed to a building frame such as a wall or ceiling. A space is obtained.

前記シート状物に形成された吸着分解層の表面は平滑であり印刷機により絵柄などを多色に印刷して化粧面を形成できるので意匠効果を高めることが出来る。印刷面は空気の透過性があり空気清浄に支障はない。更にエンボス加工機を用いて前記吸着分解層に微細なエンボス加工を行い化粧面に凹凸面を付与すると共に表面積を増加させ吸着分解機能を更に高めることが出来る。これらの加工は設備の整った加工工場で行うことで可能となり現場塗装では実施できない。   Since the surface of the adsorption / decomposition layer formed on the sheet-like material is smooth and a decorative surface can be formed by printing a pattern or the like in a multi-color with a printing machine, the design effect can be enhanced. The printing surface is air permeable and does not interfere with air cleaning. Further, the embossing machine can be used to finely emboss the adsorptive decomposition layer to give an uneven surface to the decorative surface, and the surface area can be increased to further enhance the adsorptive decomposition function. These processes can only be performed at a well-equipped processing plant and cannot be performed by on-site painting.

本発明の揮発性有機物質(VOC)及び臭気成分を吸着分解する層を形成したシート状物を現場で取着するには接着剤を用いて貼着する。ロール状に保管された前記シート状物を所望の長さに裁断し、ロール塗布機で接着剤を前記シート状物の裏面側に塗布し壁或いは天井など建築物の躯体に貼着する。施工面積が広い場合は端部を密接させて並設する。予めシート状物の幅を所定の長さで一定に裁断しておくことが必要である。更に接着剤に竹炭或いは木炭を用いた前記多孔性焼成物の粉末を混合して貼着してもよい。吸着分解層の体積を増加させる効果があり、VOC及び臭気の吸収及び/又は分解の機能が増大する。この効果は基体シートが紙または不織布であるため湿気或いは臭気の粒子が繊維の間を通過して裏面にまで達するためである。TiO2などの微粉末を用いた光触媒作用では紫外線を含む光が必要であるが、竹炭の場合は光を必要とせず微細気孔の触媒効果による吸着及び/又は分解機能でありその作用は継続的に行われる。   In order to attach the sheet-like material on which the volatile organic substance (VOC) and the odor component of the present invention are adsorbed and decomposed in the field, they are stuck using an adhesive. The sheet-like material stored in a roll shape is cut into a desired length, and an adhesive is applied to the back side of the sheet-like material with a roll coating machine, and is adhered to a building frame such as a wall or a ceiling. If the construction area is large, place the ends close together. It is necessary to cut the width of the sheet-like material at a predetermined length in advance. Further, the porous fired product powder using bamboo charcoal or charcoal as an adhesive may be mixed and pasted. There is an effect of increasing the volume of the adsorption decomposition layer, and the function of absorbing and / or decomposing VOC and odor is increased. This effect is due to the fact that the base sheet is paper or non-woven fabric, so that moisture or odor particles pass between the fibers and reach the back surface. Photocatalytic action using fine powders such as TiO2 requires light including ultraviolet rays, but bamboo charcoal does not require light and is an adsorption and / or decomposition function due to the catalytic effect of fine pores, and its action is continuous. Done.

本発明に利用される吸着分解する機能を有する塗料は、顔料としては竹炭の粉末と粘土を混練し焼成して得られる白色の多孔性焼成物粉末及び活性炭或いは麦飯石などの多孔質粒子から成る無機顔料、バインダーとしてはシリカ系の無機成分が主成分となっているものが好ましい。竹炭に限らず木炭なども利用され、塗料としては透湿性のアクリルエマルジョン樹脂塗料なども用いられる。従って最終滅却処分時にダイオキシンなどの環境破壊成分が発生若しくは残存することはない。基材シートは木材パルプより成る紙又は不織布が使用されこれらは天然素材であり環境に優しい素材である。   The paint having the function of adsorbing and decomposing used in the present invention comprises a white porous fired powder obtained by kneading and baking bamboo charcoal powder and clay as a pigment, and porous particles such as activated carbon or barley stone. As the inorganic pigment and binder, those having a silica-based inorganic component as a main component are preferable. Not only bamboo charcoal but also charcoal is used, and as a paint, a moisture-permeable acrylic emulsion resin paint is also used. Therefore, environmental destruction components such as dioxins are not generated or remain at the time of final disposal. As the base sheet, paper or non-woven fabric made of wood pulp is used, and these are natural materials and environmentally friendly materials.

本発明で得られた効果を従来技術である現場施工と塩ビ壁紙について比較検討し表1及び表2に示す。   Tables 1 and 2 show the effects obtained in the present invention by comparing the field construction and PVC wallpaper, which are conventional techniques.

竹炭の粉末及び粘土を混練し焼成して得られる白色の多孔性焼成物の粉体を塗料中に混合してなるVOCを吸着及び/又は分解する機能性塗料の塗膜層から成る吸着分解層を室内の天井或いは壁などの建築物の躯体表面に形成せしめる最良の形態は性能、施工性、意匠性、コスト及び地球環境に与える悪影響の面を考慮して、予め木材パルプからつくられる紙又は不織布の少なくとも片側面上に加工工場の塗装機を用いて必要量をコーティングし、必要に応じて印刷及び/又はエンボス加工を行いシート状物として巻き取ってロール状に保管することであり、更には該シート状物の裏面にも適宜塗装することも可能なことである。   Adsorption / decomposition layer comprising a coating layer of a functional paint that adsorbs and / or decomposes VOCs, which is obtained by mixing powder of white porous fired product obtained by kneading and firing bamboo charcoal powder and clay. The best mode for forming the wall on the building surface of the building such as the ceiling or wall of the room is paper or paper made from wood pulp in advance in consideration of performance, workability, design, cost and adverse effects on the global environment. Coating the required amount on at least one side of the nonwoven fabric using a processing plant coating machine, printing and / or embossing as necessary, winding it into a sheet and storing it in a roll; It is also possible to appropriately coat the back surface of the sheet-like material.

図1を用いて本発明の吸着分解層を形成したシート状物の構成を説明する。該シート状物1の裏面に水性接着剤5を塗布して天井面或いは壁面など建築物躯体6に貼り付けることにより前記多孔性焼成物の粉末7を含む吸着分解層2及び4を一定厚に形成させることが出来る。必要に応じて接着剤層5に前記多孔性焼成物の粉体7を混合することによりVOC及びその臭気の分解能力を増大することが可能である。これらの効果は木材パルプよりなる紙3の上面と下面及び接着剤中と図1に示すように層になって前記多孔性焼成物の粉末粒子7が存在し、VOC及び臭気成分を含む空気8がまず吸着分解層2に吸収され、吸収されない一部が通気性のある紙3を通して該紙の下面に形成された吸着分解層4に吸着され、更に吸着されない一部が接着剤中の前記多孔性焼成物の粉体に吸着され、昼夜を問わず分解され水と炭酸ガスに分解されることである。   The structure of the sheet-like material in which the adsorptive decomposition layer of the present invention is formed will be described with reference to FIG. By applying a water-based adhesive 5 on the back surface of the sheet-like material 1 and attaching it to a building housing 6 such as a ceiling surface or a wall surface, the adsorption decomposition layers 2 and 4 containing the powder 7 of the porous fired product are made to have a constant thickness. It can be formed. It is possible to increase the ability to decompose VOC and its odor by mixing the porous fired powder 7 with the adhesive layer 5 as required. These effects are obtained by the presence of the powder particles 7 of the porous fired product in the upper and lower surfaces of the paper 3 made of wood pulp and in the adhesive and in the adhesive as shown in FIG. 1, and air 8 containing VOC and odor components. Is first absorbed by the adsorption / decomposition layer 2, a part that is not absorbed is adsorbed to the adsorption / decomposition layer 4 formed on the lower surface of the paper through the air-permeable paper 3, and a part that is not further adsorbed is the porous in the adhesive. It is adsorbed by the powder of the fired fired product, decomposed regardless of day and night, and decomposed into water and carbon dioxide gas.

前記吸着分解層及び紙又は不織布は終末処理として焼却処分或いは埋立て処分する際に有害成分を排出しないことが地球を取巻く環境にとって必要であり、本発明で使用する塗料は主に天然成分及び無機成分で構成され、顔料としては竹炭の粉末と粘土を混練し焼成して得られる白色の多孔性焼成物粉末と無機顔料、バインダーとしてはシリカ系の無機成分及びメタアクリル酸エステル系ポリマーエマルションが主成分となっている。従って最終滅却処分時にダイオキシンなどの環境破壊成分が発生若しくは残存することはない。   It is necessary for the environment surrounding the earth that the adsorptive decomposition layer and paper or non-woven fabric do not discharge harmful components when incinerated or landfilled as a final treatment, and the paint used in the present invention is mainly natural components and inorganic The pigment is mainly composed of white porous fired powder obtained by kneading and baking bamboo charcoal powder and clay and inorganic pigment as pigment, and silica-based inorganic component and methacrylic ester polymer emulsion as binder. It is an ingredient. Therefore, environmental destruction components such as dioxins are not generated or remain at the time of final disposal.

繊維質の可撓性基体シートの一例としてKP125(メーカー名:AHLSTROM FINLAND 125g/m)の木材パルプを原料とする紙を用い、塗料は竹炭の粉末及び粘土を混練し焼成して得られる白色の多孔性焼成物の粉体を、シリカ系の無機成分及びメタアクリル酸エステル系ポリマーエマルションを主成分とする塗料中に混合して用いる。このような塗料として大日技研工業(株)製の塗料(商品名:ランデックススーパークロス用)が挙げられる。ベージュ色に調色された該塗料100に対してアクリル酸ソーダ1、鉱物性フッ素系撥水剤0.6、消泡剤0.5、水25の割合で配合して調整した。該調整した塗料を前記紙3の表面にナイフコーターを用いて160〜165g/mwet の割合で均一に塗布した。作業は1m幅でロール状の紙の上面に連続的に塗布しドライヤー(全長30m 80℃)の雰囲気中を2分間通過させ乾燥させて吸着分解層2を形成し巻き取ってロール状にした。 As an example of a fibrous flexible substrate sheet, paper made from wood pulp of KP125 (manufacturer name: AHLSTROM FINLAND 125 g / m 2 ) is used, and the paint is white obtained by kneading and baking bamboo charcoal powder and clay. The porous fired product powder is mixed and used in a paint mainly composed of a silica-based inorganic component and a methacrylic ester polymer emulsion. An example of such a paint is a paint (trade name: for Landex Super Cloth) manufactured by Dainichi Giken Kogyo Co., Ltd. The paint 100 prepared in a beige color was adjusted by blending sodium acrylate 1, mineral fluorine-based water repellent 0.6, defoaming agent 0.5, and water 25. The prepared paint was uniformly applied to the surface of the paper 3 at a rate of 160 to 165 g / m 2 wet using a knife coater. The work was continuously applied to the upper surface of a roll paper having a width of 1 m, passed through an atmosphere of a dryer (total length 30 m, 80 ° C.) for 2 minutes, dried to form the adsorptive decomposition layer 2 and wound up into a roll.

次にグラビア印刷機を用いベージュ色塗料が塗装された面に布目模様を1ヘッドで印刷し乾燥して巻き取った。次にエンボスマシンに布目の版を載せ布目のエンボスを施し巻き取った。最後に検品を行い50mずつの巻物としたロールの梱包を行った。   Next, using a gravure printing machine, the texture pattern was printed with one head on the surface coated with the beige color paint, dried and wound up. Next, a texture plate was placed on the embossing machine, and the texture was embossed and wound up. Finally, inspection was performed, and the rolls were rolled into 50 m rolls.

上記工程で製作されたシート状物を使用し古い居室の壁のリフォームを行った。まず既存の塩ビ壁紙を全て剥し取った。不陸のある部分はパテで穴埋め補修を行った。シート状物Aを壁の高さに合わせて切断した。   The wall of the old room was remodeled using the sheet-like material produced in the above process. First, all existing PVC wallpaper was removed. The part with unevenness was repaired with a putty. The sheet A was cut according to the height of the wall.

次にシート状物Aの裏側に壁紙ボンド(矢沢化学製)を150g/mの割合でのり付機により塗布し15分〜30分間養生した後壁紙の施工要領でシート状物の貼着施工を行った。 Next, wallpaper bond (manufactured by Yazawa Chemical Co., Ltd.) is applied to the back side of the sheet-like material A at a rate of 150 g / m 2 and cured for 15 to 30 minutes. Went.

結果竹炭の粉末を含む多孔性焼成物の粉末が配合された吸着分解層を形成したシート状物を貼る作業により均一な意匠性の高い塗膜を形成させることが出来た。この様な作業は塗装作業のような現場養生を必要とせず塗料の乾燥作業も必要とせず速い施工と均一な機能を確保出来る事となった。意匠性においても現場塗装に比べ意匠性の高い壁面が得られた。この仕様によるVOCの吸着・分解能力試験体を試験体Aとする。該試験体は裏面側にアクリル樹脂板を貼着し裏面側からの影響を排除した。   As a result, it was possible to form a uniform coating film with high designability by applying a sheet-like material on which an adsorption decomposition layer containing a powder of a porous fired product containing bamboo charcoal powder was blended. Such work does not require on-site curing like painting work, and does not require paint drying work, so it is possible to ensure fast construction and uniform function. In terms of design, wall surfaces with higher design were obtained compared to on-site painting. The test specimen A is a test specimen for VOC adsorption / decomposition ability according to this specification. The test body adhered an acrylic resin plate on the back side to eliminate the influence from the back side.

実施例1のシート状物作製において表面に竹炭の粉末を含む多孔性焼成物粉体を混合した塗料を塗布乾燥後、更に裏面に80g/mの割合で塗布し乾燥した両面に吸着分解層2及び4を形成したシート状物を用いて印刷・エンボス加工を施し巻き取る。このシート状物は実施例1と同様に施工する。この仕様によるVOCの吸着・分解能力試験体を試験体Bとする。該試験体は裏面側にアクリル樹脂板を貼着し裏面側からの影響を排除した。 In the preparation of the sheet-like material of Example 1, after applying and drying a paint mixed with a porous fired powder containing bamboo charcoal powder on the surface, it was further applied to the back surface at a rate of 80 g / m 2 and dried on both sides. The sheet-like material on which 2 and 4 are formed is printed and embossed and wound up. This sheet is constructed in the same manner as in Example 1. A specimen for VOC adsorption / decomposition ability according to this specification is designated as specimen B. The test body adhered an acrylic resin plate on the back side to eliminate the influence from the back side.

実施例2で製作されたシート状物を用いて室内の施工を行った。壁紙ボンド(矢沢化学製)100に対し竹炭の粉末を含む多孔性焼成物粉末を3%混合した接着剤層5を介在させてシート状物1の貼合わせを行った。シート状物への接着剤塗布量は150g/mであった。この仕様によるVOCの吸着・分解能力試験体を試験体Cとする。該試験体は裏面側にアクリル樹脂板を貼着し裏面側からの影響を排除した。 Indoor construction was performed using the sheet-like material produced in Example 2. The sheet-like product 1 was bonded to the wallpaper bond (manufactured by Yazawa Chemical) 100 with an adhesive layer 5 in which 3% of a porous fired product powder containing bamboo charcoal powder was mixed. The amount of adhesive applied to the sheet was 150 g / m 2 . A specimen for VOC adsorption / decomposition ability according to this specification is designated as specimen C. The test body adhered an acrylic resin plate on the back side to eliminate the influence from the back side.

本シート状物の吸着・分解性能を試験するため図2に示す5?の密閉型容器10に200ppmに調整されたアンモニアガス13を充満させ、その中に試験体12を入れ所定時間毎にガス検知管11を用いてガス濃度を測定した。この試験を吸着・分解性能試験1とする。吸着・分解性能を試験するに当り比較試験体としてVOCの吸着・分解能力を持たない塩ビ壁紙を壁紙ボンド(矢沢化学製)で5cm×10cmのアクリル板に貼り付け吸着・分解試験のブランク試験体とした。試験の結果を表5に示す。試験体Aから試験体Cにかけて1日の分解能力が高くなることが分かる。   In order to test the adsorption / decomposition performance of this sheet-like material, the ammonia gas 13 adjusted to 200 ppm is filled in a closed container 10 of 5? Shown in FIG. 2, and a test body 12 is put therein to gas every predetermined time. The gas concentration was measured using the detection tube 11. This test is called adsorption / decomposition performance test 1. As a comparative test specimen for testing adsorption / decomposition performance, PVC wallpaper without VOC adsorption / decomposition ability is attached to a 5cm x 10cm acrylic board with wallpaper bond (manufactured by Yazawa Chemical Co., Ltd.) and a blank specimen for adsorption / decomposition test It was. The test results are shown in Table 5. It can be seen that the daily decomposition ability increases from test body A to test body C.

Figure 2010094378
Figure 2010094378

24時間経過後別途調整された200ppmのアンモニアガス濃度の容器に同一試験体を入れ24時間後のアンモニア濃度を調べた。このテストを5回繰返し吸着・分解能力の変化を調べた。この試験を吸着・分解性能試験2として試験結果を表6に示す。   After the lapse of 24 hours, the same specimen was placed in a container with an ammonia gas concentration of 200 ppm, which was separately adjusted, and the ammonia concentration after 24 hours was examined. This test was repeated five times to examine changes in adsorption / decomposition ability. The test results are shown in Table 6 with this test as adsorption / decomposition performance test 2.

Figure 2010094378

この試験結果からC仕様の分解能力が最も高いことが分かる。予め意匠を付与した塗膜を接着という手段により室内の天井面或いは壁面に布設しているが接着作業が出来ない凹部・突起物が多数存在する場所には竹炭の粉末を含む白色の多孔性焼成物粉末を混合した塗料を現場で塗布して貼る作業と塗布作業の組合せにより機能性を付与することも可能である。   From this test result, it can be seen that the disassembly capability of the C specification is the highest. White porous firing containing bamboo charcoal powder in places where there are many recesses / projections that cannot be bonded, although a coating with a design applied in advance is laid on the ceiling or wall surface of the room by means of bonding. Functionality can also be imparted by a combination of a work of applying and applying a paint mixed with a product powder on site and an application work.
