【発明の属する技術分野】
本発明は、建築物の室内の建材から発生する揮発性有機物質を除去する方法に関する。
【０００２】
【従来の技術】
建築物施工後、建材等から発生する揮発性有機物質が室内空気中に蓄積した場合、従来では、このような揮発性有機物質を強制的に除去する方法がないため、窓やドアを開けて換気を行い、室外に放出して低減化する自然換気の方法がとられていた。
【０００３】
【発明が解決しようとする課題】
しかしながら、窓やドアを開けての自然換気では長期間を要し、長期間行うと屋外の埃や雨によって室内が汚れる場合がある。
さらに悪天候の場合は、窓やドアを開けての自然換気は実施できない。
特に建具や家具、あるいは床から発生する揮発性有機物質は量が多く、また、建具や家具は閉鎖してしまうために、棚板等から発散されるホルムアルデヒドやアセトアルデヒド、接着剤から発せられるトルエン、キシレン等はいつまでも発散しきれずに建材内に留まり、長時間にわたり揮発性有機物質の発散が持続された。そのため、室内の揮発性物質の濃度の上昇に大きく関与していた。
本発明は前記事情に鑑み案出されたものであって、本発明の目的は、悪天候の場合でも室内が埃や雨によって汚れることがなく、揮発性有機物質の発生しない環境を長期間保証することができる揮発性有機物質の除去方法を提供することにある。

【０００５】
本発明によれば、建具や家具、床面の建材そのものの揮発性有機物質含有量が減るため、揮発性有機物質の発生しない環境を長期間保証することができる。
【０００６】
【発明の実施の形態】
以下、本発明の実施の形態について説明する。
本発明では、建具や家具に揮発性有機物質吸着用シートを設置する。
この場合、前記揮発性有機物質吸着用シートは、棚板、引き出し等の底面積より１．１倍以上の面積を有するものが用いられる。
そして、前記揮発性有機物質吸着用シートを、建具や家具の棚板、引き出し等の底面を覆うように敷き詰めると共に、棚板や引き出しの底面の端部から起立する立ち上がり部を前記揮発性有機物質吸着用シートで覆う。棚板や引き出しの底面の端部から起立する立ち上がり部を前記揮発性有機物質吸着用シートで覆うのは、立ち上がり部からの揮発性有機物質の放出量が多いためである。
【０００７】
次に、前記揮発性有機物質吸着用シートが設置された箇所にファン等により室内空気を当てて前記箇所の空気を攪拌させる。
この場合、建具や家具が扉や引き出しなどのような開口部を有する構造のものでは、開口部を開放した状態にして前記箇所の空気を攪拌させる。
前記箇所の空気の攪拌により、前記揮発性有機物質吸着用シートが設置された建材箇所の空気が停滞することなく流動し、前記建具や家具を構成する建材からの揮発性有機物質の放出が促進される。
そして、建材から放出された揮発性有機物質を揮発性有機物質吸着用シートに吸着させる。
このようにして建具や家具に蓄積された揮発性有機物質を取り除いていき、建具や家具中に蓄積された揮発性有機物質を低減化させ、建具や家具の建材そのものの揮発性有機物質含有量を低減化する。
【０００８】
本実施の形態では、建具や家具から発生する揮発性有機物質を揮発性有機物質吸着用シートにより、揮発性有機物質の発生場所である建具や家具において直に吸着するため、建具や家具中に蓄積された揮発性有機物質を効果的に低減することができる。
したがって、建具や家具の揮発性有機物質含有量を効果的に低減できるので、以後、室内の空気中のＶＯＣ濃度（揮発性有機物質濃度）を低い値に維持することができる。
【０００９】
また、本発明では、床面に揮発性有機物質吸着用シートを設置する。
次に、前記揮発性有機物質吸着用シートが設置された箇所にファン等により室内空気を当てて前記箇所の空気を攪拌させる。
前記箇所の空気の攪拌により、前記揮発性有機物質吸着用シートが設置された建材箇所の空気が停滞することなく流動し、前記床面を構成する建材からの揮発性有機物質の放出が促進される。
そして、建材から放出された揮発性有機物質を揮発性有機物質吸着用シートに吸着させる。
このようにして床面に蓄積された揮発性有機物質を取り除いていき、床面中に蓄積された揮発性有機物質を低減化させる。
【００１０】
本実施の形態では、床面から発生する揮発性有機物質を揮発性有機物質吸着用シートにより、揮発性有機物質の発生場所である床面において直に吸着するため、床面に蓄積された揮発性有機物質を効果的に低減することができる。
したがって、床面の揮発性有機物質含有量を効果的に低減できるので、以後、室内の空気中のＶＯＣ濃度（揮発性有機物質濃度）を低い値に維持することができる。
【００１１】
本発明において建具は、一戸建て住宅、集合住宅に建築時から設置されているものを示す。例としては、下駄箱、クローゼット、もの入れ、サイドボード、洗面台、キッチン、食器だな、作り付け本棚、押し入れ、床下収納庫、物置がある。
また、本発明において家具は、後に住居内に持ち込まれたのもで、例としては、洋服ダンス、本棚、机、いす、応接セット、ベンチチェスト、和ダンス等がある。
また、本発明において、揮発性有機物質吸着用シートが設置された箇所に室内空気を当てて前記箇所の空気を攪拌させるファンは、扇風機やエアコン等を含むものである。
【００１２】
前記揮発性有機物質吸着用シートの材料として、多孔性物質を成分とした吸着剤を使用できる。この場合の多孔性物質として、例えば、活性炭、漆喰、珪藻土、酸化チタン等の光触媒、備長炭、コルク材、シリカゲル等が挙げられる。
そして、これらをシート状にして使用する。
シートの形式としては、不織布や和紙、加工紙、ガーゼ等の通気性のよい素材で前記吸着剤を挟み込んだもの、あるいは、吸着剤を含浸させたもの、あるいは、吸着剤を布地に織り込んだもの等が挙げられる。
前記不織布や和紙、加工紙、ガーゼ等の素材は可燃ごみとして処分でき、使用後、揮発性有機物質吸着用シートが産業廃棄物とならない。また、不織布や和紙、加工紙、ガーゼ等の素材は、その上に靴や洋服等を置け、便利となる。
【００１３】
室内を加温することで、建具や家具、床面も加温され、建具や家具、床面からの揮発性有機物質の放出が促進される。そして、加温中は揮発性有機物質の放出により空気中の濃度が徐々に高くなり、やがて平衡状態となって放出速度が弱まる。
そのため、吸着剤により室内に浮遊する揮発性有機物質を吸着することで、あるいは、空気清浄器により室内に浮遊する揮発性有機物質を吸着することで、あるいは、換気扇等により室内の換気を行い室内に浮遊する揮発性有機物質を室外に排出することで、揮発性有機物質濃度を下げる。
このように揮発性有機物質濃度を下げることで、建材からの揮発性有機物質の放出を再度促進させ、より効果的に揮発性有機物質吸着用シートで吸着し、除去できる。
【００１４】
加温する方法としては、電熱器、ガスヒーター、その他のストーブ、ホットカーペット、エアーコンディショナー床暖房等がある。これらにより室温を上昇させる。室温は３０℃以上好ましくは、３５℃以上がよい。
加温時間は、０．１時間以上でも効果を発揮するが、好ましくは、５時間以上がよい。
換気は加温後に行うが、３０分以上が好ましい。部屋の広さや建具や家具の表面積にも影響を受ける。
揮発性有機物質の臭気が激しい場合は、加温前に窓を開けるなどして換気を３０分以上行うとさらに効果が上がる。
【００１５】
トルエン、キシレン等のような揮発性有機物質は、揮発性有機物質吸着用シート設置後あるいは、加温中に除湿器により室内の湿度を下げると、建具や家具、床面を構成する建材からの揮発性有機物質の放出量をさらに上昇させることができる。
また、ホルムアルデヒドやアセトアルデヒド、アルコール類等のように水に可溶な揮発性有機物質は、揮発性有機物質吸着用シート設置後あるいは、加温中に加湿器により室内の湿度を上げると、建材からの揮発性有機物質の放出量をさらに上昇させることができる。
そして、室内を除湿し、あるいは、加湿することで、建材からの揮発性有機物質の放出が促進されるが、揮発性有機物質の放出により空気中の濃度が徐々に高くなり平衡状態となると放出速度が弱まる。そこで、加温の場合と同様に、吸着剤により室内に浮遊する揮発性有機物質を吸着することで、あるいは、空気清浄器により室内に浮遊する揮発性有機物質を吸着することで、あるいは、換気扇等により室内の換気を行い室内に浮遊する揮発性有機物質を室外に排出することで、揮発性有機物質濃度を下げ、建材からの揮発性有機物質の放出を更に促進させる。

By heating the room, the joinery, furniture, and floor are also warmed, and release of volatile organic substances from the joinery, furniture, and floor is promoted. During heating, the concentration in the air gradually increases due to the release of the volatile organic substance , and eventually the equilibrium state is reached and the release rate is reduced.
Therefore, by adsorbing the volatile organic substances floating in chamber by the adsorbent, or by adsorbing the volatile organic substances floating in chamber by the air cleaner, or indoor perform ventilation of the room by ventilating fan or the like The concentration of volatile organic substances is lowered by discharging volatile organic substances floating in the room to the outside.
By thus reducing the volatile organic substance concentration, the release of volatile organic substances from building materials is again accelerated, and more effectively volatile organic substances adsorbed by the adsorbent sheet can be removed.
[0014]
Heating methods include electric heaters, gas heaters, other stoves, hot carpets, and air conditioner floor heating. These raise the room temperature. The room temperature is 30 ° C or higher, preferably 35 ° C or higher.
The effect is exhibited even when the heating time is 0.1 hour or longer, but preferably 5 hours or longer.
Ventilation is performed after warming, but is preferably 30 minutes or longer. It is also affected by the size of the room and the surface area of furniture and furniture.
When the odor of volatile organic substances is intense, the effect is further improved by ventilating for 30 minutes or more by opening a window before heating.
[0015]
Volatile organic substances such as toluene, xylene, etc. can be removed from the building materials, furniture, and building materials that constitute the floor surface if the indoor humidity is lowered by the dehumidifier after the installation of the volatile organic substance adsorption sheet or during heating. The amount of volatile organic substances released can be further increased.
Also, volatile organic substances that are soluble in water, such as formaldehyde, acetaldehyde, alcohols, etc., can be removed from building materials if the humidity in the room is increased by a humidifier after the volatile organic substance adsorption sheet is installed or during heating. The amount of released volatile organic substances can be further increased.
And by dehumidifying or humidifying the room, the release of volatile organic substances from building materials is promoted, but when the concentration in the air gradually increases due to the release of volatile organic substances , the release occurs. Speed decreases. Therefore, as in the case of heating, or by adsorbing the volatile organic substances floating in the indoor or by adsorbing the volatile organic substances floating in chamber by the air purifier, the adsorbent, ventilators By ventilating the room by such means and discharging the volatile organic substance floating indoors to the outside, the concentration of the volatile organic substance is lowered and the release of the volatile organic substance from the building material is further promoted.

【The invention's effect】
According to the present invention, the volatile organic substances accumulated in the joinery, furniture, and floor are directly adsorbed by the volatile organic substance adsorption sheet on the joinery, furniture, and floor where they are generated. The volatile organic substance can be efficiently removed from the building material constituting the floor surface, and the VOC (volatile organic substance) concentration in the indoor air can be effectively reduced.
Further, in the present invention, the volatile organic substance is directly adsorbed by the volatile organic substance adsorbing sheet on the joinery, furniture, and floor surface, so that it takes less time to ventilate. Therefore, the VOC is not affected by the outside weather. The concentration can be reduced.
In addition, the VOC concentration in the room can be effectively reduced by a few simple processes, and furthermore, volatile organic substances are adsorbed directly on the fittings, furniture, and floors where they are generated, so there is no need for ventilation. However, the VOC concentration in the room can be reduced.
VOCs are also generated from clothes cleaning materials, shoe creams, insect repellents, and the like housed in joinery and furniture, but these can also be reduced at the same time.
In addition, volatile organic substances are efficiently removed from the building materials, furniture, and building materials that make up the floor, and the content of volatile organic substances in the building materials, furniture, and floor building materials themselves is reduced. The period can be guaranteed.
