Description

【0001】
【発明の属する技術分野】
本発明は、例えば床フローリング材等の室内配設部材を加温してこれに含まれている有害ガスの発生の原因となる物質を除去する方法並びにシートに関するものである。
【0002】
【従来の技術】
最近、人体に有害なホルムアルデヒドやVOC(揮発性有機化合物)等の有害ガスが竣工間もない建物の室内空間に発生し問題になっている。これらの有害ガスは、主に床フローリング材等の内装材に使用される合板材から発生していることが確認されている。合板材の製造に使用されるフェノール系、尿素系またはメラニン系等の接着剤に含まれている特定の物質が有害ガスの発生原因となっている。
【0003】
そこで、従来から、有害ガスによる室内汚染を防止するためにベイクアウト法が実施されている。このベイクアウト法は、建物の竣工前の段階において、有害ガスを発生する室内の部材に対して有害ガスの発生を促進させる処理を施してその原因となる物質を予め除去しておこうとするものである。有害ガスの発生促進にあたっては、室内空間全体を約35〜40℃程度の高温状態に1〜2日間加温装置により加熱し続ける。この加温によって、室内空間に面して配設された床フローリング材等の部材からは、通常時に比べて大量の有害ガスが発生して、有害ガスの発生原因物質が除去される。除去終了後は、空気の入れ換えにより室内空間の有害ガスを室外に排出する。
【0004】
【発明が解決しようとする課題】
しかしながら、ベイクアウト法は、室内空間全体を加温しなければならないため、次のような問題を生じていた。まず、床フローリング材等に対し十分に加熱するのに時間がかかるので、有害ガス発生原因物質の除去が完了するまでの間に相当な日数を要した。また、除去作業終了後の室内空気の入れ換えや大掛かりな加温装置の搬入及び搬出により作業時間の長期化を招いていた。さらに、加温装置が大掛かりでエネルギーロスも大きく、コストが嵩んでいた。
【0005】
本発明は、前記事情に鑑みてなされたものであって、その目的は、床フローリング材等の室内配設部材に含まれる有害ガス発生原因物質を低コストかつ短時間で除去することが可能な有害ガス発生原因物質の除去方法並びにその除去シートを提供することにある。
【0006】
【課題を解決するための手段】
前記目的を達成するために本発明に係る有害ガス発生原因物質の除去方法にあっては、有害ガス発生原因物質を含有する室内配設部材の外側表面にこれを覆って、周辺温度を上昇させる発熱層と、前記発熱層よりも外側に配置される断熱材により形成された断熱層と、有害ガスを捕捉するガス吸着材により形成されたガス捕捉層とを設置した後、前記断熱層で断熱しつつ前記発熱層により前記室内配設部材を加温して当該室内配設部材から発生した有害ガスを前記ガス捕捉層で捕捉することを特徴とする。
【0007】
この方法によれば、有害ガス発生原因物質を含有する室内配設部材を発熱層で覆って加温しつつ断熱材で覆って熱が外部に逃げるのを防止できるから、当該部材に対し行う有害ガスの発生を促す処理を熱的ロスが少なく効率的に行うことができる。一方、室内配設部材から促されて発生した有害ガスについては、前記部材の表面を覆って設置したガス捕捉層で捕捉するから、外部にあまり漏出させることなく有害ガスを捕捉することができる。従って、従来のベイクアウト法に比べて効率よく加温を行えるとともに大掛かりな加温装置の設置も換気の手間も必要ないから作業が極めて短時間で済み、またエネルギーロスも少なく低コストで実施することできる。
【0008】
さらに、前記発熱層、前記保温層及び前記ガス吸着層を設置の際に予め一体化しておけば、各層の設置作業を簡略化することができる。
【0009】
他方、本発明に係る有害ガス発生原因物質の除去シートにあっては、有害ガス発生原因物質を含有する室内配設部材の外側表面にこれを覆って仮設されるシートであって、前記室内配設部材を加温する発熱層と、前記発熱層よりも外側表面に配置され前記発熱層の生成熱を遮断する断熱層と、前記室内配設部材から発生した有害ガスを捕捉するガス吸着材により形成されたガス吸着層とを備えたことを特徴とする。このシートにより、室内配設部材を発熱層で覆って加温しつつ断熱層で覆って熱が外部に逃げるのを防止することができるから、室内配設部材を熱的ロスが少なくきわめて効率的に加温できるとともに、室内配設部材をガス捕捉層で覆ってこれより発生する有害ガスを外部にあまり漏出させることなく捕捉することができるから、低コストかつ短時間に作業を済ませることができる。
【0010】
【発明の実施の形態】
以下に本発明に係る有害ガス発生原因物質の除去方法並びにその除去シートの実施の形態について添付図面を用いて説明する。
【0011】
図1は、本発明に係る有害ガス発生原因物質の除去方法の一実施形態を示したものである。この方法は、室内配設部材2を加温してこれに含まれている有害ガス発生原因物質を除去するものである。除去の対象となる室内配設部材2は、例えば床フローリング材等の内装材や新建材に使用される合板材をはじめ、このほか家具類等の有害ガス発生原因物質を含有する物を含む。これらの室内配設部材2は、既に建物の室内空間に配設されたものでもよく、また工場の製造時や運搬時の段階のものであってもかまわない。
【0012】
この方法で有害ガス発生原因物質を除去する際には、まず、室内配設部材2の表面にこれを覆ってガス捕捉層4、発熱層6及び断熱層8を設ける。断熱層8は発熱層よりも外側に配設する。本実施例では、室内配設部材2の表面から外部10に向かってガス捕捉層4、発熱層6、断熱層8の順に配設されている。これらガス捕捉層4、発熱層6及び断熱層8は、それぞれ各層個別に設置してもよく、また設置を効率的に行うために予め一体化して1枚のシートに形成してから設置してもよい。以下に各層について詳しく説明する。
【0013】
発熱層6は、熱を放出する発熱体により形成されている。発熱体は、電熱式のものをはじめ、この他熱媒式のものであってもかまわない。本実施例の発熱層6は1枚の薄肉なシート状の発熱体により形成されている。そして、発熱体の熱放出により周辺温度を上昇させて室内配設部材2を加温する。発熱層6と室内配設部材2とは熱伝達効率を高めるためになるべく相互に密着させる。
【0014】
一方、断熱層8は、例えばグラスウールやロックウール等の無機繊維系断熱材、例えばポリスチレンやウレタン等の発泡プラスチック系断熱材またはその他の断熱材料から形成される。本実施例の断熱層8は1枚の薄肉なシート状の断熱材により形成されている。断熱層8は発熱層6の外側に配設されて発熱層6からの放出熱が外部10に逃げないようにこれを遮断する。断熱層8は発熱層6からの熱ロスが少ないようになるべく発熱層6に密着させる。
【0015】
他方、ガス捕捉層4は、例えば活性炭やゼオライト等の物理系吸着剤または各種金属塩等からなる化学系吸着剤などをはじめとする有害ガスの捕捉が可能なガス捕捉剤により形成されたガス吸着材から形成されている。本実施例のガス捕捉層4は1枚の薄肉なシート状のガス吸着材により形成されている。ガス捕捉層4は、室内配設部材2から放出される有害ガスを捕捉する。ガス捕捉層4は、発生した有害ガスを効率よく捕捉するためになるべく室内配設部材2の表面に密着させる。
【0016】
以上のようにガス捕捉層4、発熱層6及び断熱層8を室内配設部材2の表面に設けた後、有害ガス原因物質の除去作業を行う。この作業では、発熱層6で室内配設部材2を加温して当該部材からの有害ガスの発生を促進させる。ここで室内配設部材2からは常温の場合に比べて大量の有害ガスが発生する。室内配設部材2から発生した有害ガスは、ガス捕捉層4や発熱層6、断熱層8の各層に遮断されて外部10にあまり漏出することなくガス捕捉層4に捕捉される。これにより、室内配設部材2に含まれている有害ガス発生原因物質を短時間で効率的に除去することができる。特に、この方法では、室内配設部材2の表面のみを加温するから、従来のベイクアウト法に比べて、熱的ロスも少なくきわめて低コストで実施することができる。
【0017】
有害ガス発生原因物質の除去作業終了後、ガス捕捉層4、発熱層6及び断熱層8を室内配設部材2の表面から撤去して作業を完了させる。
【0018】
《他の実施の形態》
ガス捕捉層4については、発熱層6と断熱層8との間または断熱層6よりもさらに外側に配設してもよい。この場合、発熱層6と断熱層8との間にガス捕捉層4を配設するときには断熱層8に、また断熱層8の外側にガス捕捉層4を配設するときには発熱層6及び断熱層8の双方に通気性を持たせる。
【0019】
ガス捕捉層4、発熱層6及び断熱層8については、それぞれ個別に区分されている必要はなく、単一の層に複合されて形成されていてもよい。
【0020】
【発明の効果】
以上発明の実施の形態で詳しく説明したように本発明に係る有害ガス発生原因物質の除去方法並びに除去シートによれば、有害ガス発生原因物質を含有する室内配設部材の外側表面を発熱層で覆って加温しつつ断熱層で覆って熱が外部に逃げるのを防止するから、当該部材に対し有害ガスの発生を促す処理を熱的ロスが少なく効率的に行うことができる。また、発生した有害ガスについては、室内配設部材を覆って設置したガス捕捉層で外部にあまり漏出させることなく捕捉することができ、換気の手間を省くことができる。従って、従来のベイクアウト法に比べて大掛かりな加温装置も必要なく、有害ガス発生原因物質の除去を低コストかつ短時間で実施することができる。

Recently, harmful gases such as formaldehyde and VOC (volatile organic compounds) that are harmful to the human body have been generated in the indoor space of buildings that have just been completed. It has been confirmed that these harmful gases are mainly generated from plywood materials used for interior materials such as flooring materials. Certain substances contained in adhesives such as phenolic, urea or melanin used in the manufacture of plywood are responsible for the generation of harmful gases.

[Problems to be solved by the invention]
However, the bakeout method has caused the following problems because the entire indoor space has to be heated. First, since it takes time to sufficiently heat the flooring material and the like, it took a considerable number of days to complete the removal of the harmful gas generation cause substances. In addition, the replacement of room air after the completion of the removal work and the introduction and removal of large-scale heating devices have led to prolonged work time.

[0010]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of a method for removing a harmful gas generating substance and a removal sheet thereof according to the present invention will be described below with reference to the accompanying drawings.
[0011]
FIG. 1 shows an embodiment of a method for removing a harmful gas generation causative substance according to the present invention. In this method, the indoor arrangement member 2 is heated to remove harmful gas generation substances contained therein. The indoor arrangement member 2 to be removed includes, for example, interior materials such as floor flooring materials and plywood materials used for new building materials, as well as materials containing harmful gas generating substances such as furniture. These indoor arrangement members 2 may be those already arranged in the indoor space of the building, or may be those at the time of factory manufacture or transportation.
[0012]
When removing the harmful gas generation causative substance by this method, first, the gas trapping layer 4, the heat generating layer 6 and the heat insulating layer 8 are provided on the surface of the indoor arrangement member 2 so as to cover it. The heat insulating layer 8 is disposed outside the heat generating layer. In this embodiment, the gas capturing layer 4, the heat generating layer 6, and the heat insulating layer 8 are arranged in this order from the surface of the indoor arrangement member 2 toward the outside 10. The gas capturing layer 4, the heat generating layer 6 and the heat insulating layer 8 may be installed individually for each layer, or in order to efficiently perform the installation, the gas capturing layer 4, the heat generating layer 6 and the heat insulating layer 8 may be installed after being integrated into one sheet in advance. Also good. Each layer will be described in detail below.
[0013]
The heat generating layer 6 is formed of a heat generator that releases heat. The heating element may be an electric heating type or other heating medium type. The heat generating layer 6 of this embodiment is formed by a thin sheet-like heat generating element. Then, the ambient temperature is raised by the heat release of the heating element to heat the indoor arrangement member 2. The heat generating layer 6 and the indoor arrangement member 2 are brought into close contact with each other as much as possible in order to increase heat transfer efficiency.
[0014]
On the other hand, the heat insulating layer 8 is formed of an inorganic fiber heat insulating material such as glass wool or rock wool, for example, a foamed plastic heat insulating material such as polystyrene or urethane, or other heat insulating material. The heat insulating layer 8 of the present embodiment is formed of one thin sheet-like heat insulating material. The heat insulating layer 8 is disposed outside the heat generating layer 6 and blocks the heat released from the heat generating layer 6 from escaping to the outside 10. The heat insulating layer 8 is adhered to the heat generating layer 6 as much as possible so that the heat loss from the heat generating layer 6 is small.
[0015]
On the other hand, the gas trapping layer 4 is a gas adsorbent formed by a gas trapping agent capable of trapping harmful gases including a physical adsorbent such as activated carbon and zeolite, or a chemical adsorbent composed of various metal salts. It is made of material. The gas trapping layer 4 of this embodiment is formed of a single thin sheet-like gas adsorbent. The gas capturing layer 4 captures harmful gases released from the indoor member 2. The gas capturing layer 4 is brought into close contact with the surface of the indoor arrangement member 2 as much as possible in order to efficiently capture the generated harmful gas.
[0016]
As described above, after the gas capturing layer 4, the heat generating layer 6, and the heat insulating layer 8 are provided on the surface of the indoor arrangement member 2, the harmful gas causing substance is removed. In this operation, the indoor arrangement member 2 is heated by the heat generating layer 6 to promote generation of harmful gas from the member. Here, a large amount of harmful gas is generated from the indoor arrangement member 2 as compared with the case of normal temperature. The harmful gas generated from the indoor arrangement member 2 is blocked by the gas trapping layer 4, the heat generating layer 6, and the heat insulating layer 8, and is trapped by the gas trapping layer 4 without leaking to the outside 10. Thereby, the harmful gas generation cause substance contained in the indoor arrangement member 2 can be efficiently removed in a short time. In particular, in this method, since only the surface of the indoor arrangement member 2 is heated, the thermal loss is small as compared with the conventional baking-out method, and the method can be implemented at a very low cost.
[0017]
After the removal of the harmful gas generation causative substance is completed, the gas trapping layer 4, the heat generating layer 6 and the heat insulating layer 8 are removed from the surface of the indoor arrangement member 2 to complete the operation.
[0018]
<< Other Embodiments >>
The gas capturing layer 4 may be disposed between the heat generating layer 6 and the heat insulating layer 8 or further outside the heat insulating layer 6. In this case, when the gas capturing layer 4 is disposed between the heat generating layer 6 and the heat insulating layer 8, the heat insulating layer 8 is disposed. When the gas capturing layer 4 is disposed outside the heat insulating layer 8, the heat generating layer 6 and the heat insulating layer are disposed. Provide both 8 with air permeability.
[0019]
The gas trapping layer 4, the heat generating layer 6 and the heat insulating layer 8 do not have to be individually divided, and may be formed in a single layer.
[0020]
【The invention's effect】
As described above in detail in the embodiment of the present invention, according to the method for removing harmful gas generation causative substances and the removal sheet according to the present invention, the outer surface of the indoor arrangement member containing the harmful gas generation causative substances is formed by a heat generating layer. Since heat is prevented from escaping to the outside by covering with a heat insulating layer while being covered and heated, the process for promoting the generation of harmful gas to the member can be efficiently performed with little thermal loss. In addition, the generated harmful gas can be captured by the gas capturing layer installed so as to cover the indoor arrangement member without leaking much outside, and the labor of ventilation can be saved. Therefore, there is no need for a large-scale heating device as compared with the conventional baking out method, and the removal of the harmful gas generation cause substance can be carried out at a low cost and in a short time.
