Description

本発明は、保存施設の収蔵庫等で病害虫や黴の駆除を目的として、燻蒸ガスで燻蒸処理した後の残留した燻蒸ガスや、建材等から発散する揮発性の有機化合物(以下、VOCと呼称する)、酸性やアルカリ性の大気汚染ガスを除去する紙に関するものである。詳しくは、燻蒸処理した後に庫内の空気を強制的に換気して安全な管理濃度に到達させた後で、庫内の収蔵品の種類や配置状態の違い、あるいは温湿度等の環境変化によって燻蒸ガスの脱着が起こり、庫内の燻蒸ガス濃度が管理濃度以上に再上昇することを防ぐためのものである。さらには新築やリフォーム直後の建材や家具から発散するVOC等を効率よく除去したり、大気汚染ガスを吸着除去したりするための汚染ガス除去紙に関するものである。   The present invention is intended to control pests and fumigation in storage facilities of storage facilities, etc., and the remaining fumigation gas after fumigation treatment with fumigation gas and volatile organic compounds emanating from building materials (hereinafter referred to as VOC). It is related to paper that removes acidic and alkaline air pollutant gases. Specifically, after fumigation treatment, the air in the cabinet is forcibly ventilated to reach a safe control concentration, and then depending on the type of stored items in the warehouse, the state of the arrangement, or environmental changes such as temperature and humidity This is intended to prevent the fumigation gas from being desorbed and the fumigation gas concentration in the warehouse from rising again above the control concentration. Furthermore, the present invention relates to a pollutant gas removing paper for efficiently removing VOCs and the like emanating from building materials and furniture immediately after a new construction or renovation, or for removing atmospheric pollutant gas by adsorption.

文化財に限らず検疫や農業分野において、病害虫や黴の駆除を目的として薬剤による燻蒸処理が行われてきたことは周知の事実である。我が国においては、臭化メチルがその優れた殺虫力、浸透性等の特徴を有することから文化財用の殺虫燻蒸剤として広範囲に使用されてきた。特に臭化メチルと酸化エチレンとの混合ガスによる燻蒸剤は効果的に殺虫・殺菌が行われるために、美術館、博物館、図書館、文書館等において資料や作品(以下、収蔵品と呼称する)の新規受け入れ時や、毎年、あるいは隔年毎に行われる収蔵品の定期的な燻蒸用薬品として使用されてきた。   It is a well-known fact that chemical fumigation has been carried out not only for cultural properties but also for quarantine and agriculture fields in order to control pests and insects. In Japan, methyl bromide has been widely used as an insecticidal fumigant for cultural properties because of its excellent insecticidal power and permeability. In particular, fumigants using a mixed gas of methyl bromide and ethylene oxide are effectively insecticidal and sterilized, so materials and works (hereinafter referred to as collections) in museums, museums, libraries, archives, etc. It has been used as a regular fumigant for new collections, and every year or every other year.

ところが、1997年の第9回モントリオール議定書締約国会議において、オゾン層の破壊と発癌性の恐れのある臭化メチル(オゾン破壊係数が0.2以上のものが規制の対象となるが、臭化メチルのオゾン破壊係数は0.6であり、規制の対象となっている)の生産と使用を2005年までに全廃することが合意された。そこで臭化メチルの代替燻蒸剤としてヨウ化メチル(オゾン破壊係数=0.02)や酸化プロピレン(オゾン破壊係数=0)による燻蒸処理と、その有効性や安全性を確認する検討が開始された。   However, at the 9th Montreal Protocol Conference of the Parties in 1997, methyl bromide (with ozone depletion coefficient of 0.2 or more is subject to regulation, which may cause ozone layer destruction and carcinogenicity. It has been agreed that the production and use of methyl (the ozone depletion factor of 0.6 is subject to regulation) will be abolished by 2005. Therefore, fumigation treatment with methyl iodide (ozone destruction coefficient = 0.02) or propylene oxide (ozone destruction coefficient = 0) as an alternative fumigation agent for methyl bromide, and studies to confirm its effectiveness and safety were started. .

一般的に日本で行われてきた従来の燻蒸作業は、収蔵庫内を1mあたり100g程度の燻蒸剤(臭化メチル86%+酸化エチレン14%)で24時間処理した後、数ppm以下の安全な管理濃度に達するまで強制的に庫内空気の換気を数日間に渡り繰り返し行って終了する。しかしながら、収蔵品の種類と収蔵庫内の配置状態の違いや、温湿度等の環境変化によって収蔵品に吸着されていた燻蒸ガスの脱着が起こり、一旦は安全な管理濃度に達した収蔵庫内の燻蒸ガス濃度が、数十ppmにまで再上昇してしまうという問題点を抱えている。そのために収蔵庫内に残留した、あるいは収蔵品から脱着した低濃度の燻蒸ガスを効果的に除去する安価な材料が求められてきた。 In general, the conventional fumigation work that has been carried out in Japan is carried out for 24 hours with a fumigant (methyl bromide 86% + ethylene oxide 14%) of about 100 g / m 3 in the storage, and then several ppm or less. Forcibly ventilate the inside air for several days until a safe control concentration is reached. However, the desorption of the fumigation gas adsorbed to the stored product due to the difference in the type of stored product and the state of arrangement in the stored product and the environmental change such as temperature and humidity, etc. The problem is that the fumigation gas concentration rises to several tens of ppm. Therefore, there has been a demand for an inexpensive material that effectively removes low-concentration fumigation gas remaining in the storage or desorbed from the storage.

また、一方において、近年、新築やリフォームした入居者の「シックハウス症候群」が問題となっている。その原因の一部は、建材や家具から発散するホルムアルデヒド、キシレン、トルエンといったVOCや、硫化水素、酢酸といった悪臭ガスに起因して発生すると考えられ、建築物の環境を一段と改善しようとする規制が導入されるようになった。また、アンモニア、亜硫酸ガス、硝酸ガス等のアルカリ性や酸性の大気汚染ガスも以前から問題とされており、文化財保存施設等においても収蔵品の汚染ガスによる変色や劣化を防ぐための対策が採られるようになってきている。このように人や物に対して安全な環境を提供するために、新築やリフォーム直後の建築空間の汚染ガスを効果的に除去できる材料も求められている。   On the other hand, in recent years, “sick house syndrome” of newly constructed or renovated residents has become a problem. Some of the causes are thought to be caused by VOCs such as formaldehyde, xylene, and toluene that emanate from building materials and furniture, and odorous gases such as hydrogen sulfide and acetic acid, and there are regulations to further improve the environment of buildings. Introduced. In addition, alkaline and acidic air pollutant gases such as ammonia, sulfurous acid gas, and nitric acid gas have been a problem for some time, and measures to prevent discoloration and deterioration due to polluted gas in the collection of cultural properties are also taken. It is getting to be. Thus, in order to provide a safe environment for people and things, there is a demand for a material that can effectively remove the pollutant gas in a building space immediately after a new construction or renovation.

本発明によれば、燻蒸処理後の換気によって収蔵庫内空気の燻蒸ガス濃度を数ppm以下の安全な管理濃度まで低下させてから、1mあたり0.025〜0.1m(使用量:気積率A/V=0.025〜0.1m−1)の汚染ガス除去紙を数日間、天井から或いは壁に沿って吊したり、収蔵品や収納棚を被覆したりすることによって、残留や脱着した低濃度の燻蒸ガスを効果的に除去できるものである。また、前記と同様の方法で新築或いはリフォームされた建築空間において1週間〜数ヶ月使用してVOC等の汚染ガスを効果的に除去し、併せて大気汚染ガスをも吸着除去し、使用後は一般のゴミ処理として焼却廃棄できる安価な材料を提供することが出来る。さらには、使用にあたって任意の大きさに裁断する際、端部から汚染ガス吸着性粉体がこぼれ落ちて周囲を汚す恐れもなく、形状の異なる収蔵品を直接包帯状に巻くことも可能で、簡単かつ安全に使用することのできる汚染ガス除去紙を提供することができる。 According to the present invention, the fumigation gas concentration of the air in the storage is reduced to a safe management concentration of several ppm or less by ventilation after the fumigation treatment, and then 0.025 to 0.1 m 2 per 1 m 3 (amount used: By suspending the pollutant gas removing paper having a volume ratio A / V = 0.025 to 0.1 m −1 ) for several days from the ceiling or along the wall, or covering the storage items or storage shelves, Residual and desorbed low-concentration fumigation gas can be effectively removed. In addition, it effectively removes pollutant gases such as VOC by using it for one week to several months in a newly constructed or renovated building space in the same manner as described above, and also adsorbs and removes air pollutant gases. It is possible to provide an inexpensive material that can be incinerated and discarded as a general waste disposal. Furthermore, when cutting to any size for use, there is no risk of contaminating gas adsorbing powder spilling from the edge and contaminating the surroundings, and it is also possible to directly wrap collections with different shapes in bandages In addition, it is possible to provide a contaminated gas removing paper that can be used safely.

本発明者等は、前述した問題点を解決するために、臭化メチル代替燻蒸剤であるヨウ化メチルや酸化プロピレンに対して優れた吸着性能を有する粉体と、VOCや大気汚染ガス等の汚染ガスに対して優れた吸着性能を有する粉体を見出すための検討を行った。次いで製紙用繊維を主体とした3層以上の多層抄き合わせ紙の中層に一定量以上のガス吸着性粉体を担持させ、その中層の表裏に製紙用繊維を主体とした紙を抄き合わせ、ガス吸着性粉体の脱落を防止して収蔵品を汚さないような構成としたのである。また、担持させる材料として製紙用繊維を主体とした紙を使用することによって、一般のゴミ処理で焼却廃棄が可能な形態とした。   In order to solve the above-described problems, the present inventors have developed a powder having excellent adsorption performance for methyl iodide and propylene oxide, which are substitutes for methyl bromide, and VOC, air pollutant gas, etc. A study was conducted to find a powder with excellent adsorption performance against pollutant gases. Next, a certain amount or more of gas-adsorbing powder is supported on the middle layer of three or more layers of multi-layered paper mainly composed of paper-making fibers, and paper made mainly of paper-making fibers is laminated on the front and back of the middle layer. The gas adsorbing powder is prevented from falling off and the stored product is not soiled. In addition, by using paper mainly made of papermaking fibers as the material to be carried, it is possible to incinerate by general waste disposal.

本発明者等は、優れたガス吸着性能を有する粉体を見出すために、各種の粉体を以下に述べるような2つのグループに分けて検討を行った。また、ガス吸着性能評価として、ポリプロピレンに低融点のポリエチレンを被覆した複合繊維よりなる坪量40g/mの不織布で作られた10×10cmの袋の中に、各種のガス吸着性粉体を0.5g封入して評価用のサンプルとした。さらにブランクとして、木材パルプ単独よりなる坪量50g/mの紙を0.5g用意した。これらのサンプルを温度23℃、相対湿度50%の条件下で24時間放置して前処理し、次いでこのサンプルをテドラーバッグに入れて脱気し、既知の濃度に調製した各種のガス2リットルを注入して直ちに検知管(ガステック(株)製造)を使用して、その濃度を温度23℃の条件下で測定し、これを初期濃度とした。次に温度を23℃のまま5時間放置した後で再度テドラーバッグ内の残存ガス濃度を測定した。各サンプルのガス吸着性能は、初期濃度から残存ガス濃度を差し引きし、各ガス吸着性粉体1gあたりの吸着量(μg)として換算した。初期濃度は酸化プロピレンとヨウ化メチルが300ppm、酢酸、ホルムアルデヒド、硫化水素、キシレン、トルエン、アンモニア、亜硫酸ガス、硝酸ガスは100ppmを基準とした。 In order to find a powder having excellent gas adsorption performance, the present inventors examined various types of powder in two groups as described below. For gas adsorption performance evaluation, various gas adsorbent powders were placed in a 10 × 10 cm bag made of a nonwoven fabric having a basis weight of 40 g / m 2 made of a composite fiber obtained by coating polypropylene with a low melting point polyethylene. 0.5 g was enclosed and used as a sample for evaluation. Furthermore, 0.5 g of paper having a basis weight of 50 g / m 2 made of wood pulp alone was prepared as a blank. These samples are pretreated for 24 hours under conditions of a temperature of 23 ° C. and a relative humidity of 50%, then the samples are put in a Tedlar bag, degassed, and injected with 2 liters of various gases prepared to known concentrations. Then, immediately using a detector tube (manufactured by Gastec Co., Ltd.), the concentration was measured under the condition of a temperature of 23 ° C., and this was taken as the initial concentration. Next, after leaving the temperature at 23 ° C. for 5 hours, the residual gas concentration in the Tedlar bag was measured again. The gas adsorption performance of each sample was calculated by subtracting the residual gas concentration from the initial concentration, and converting it as an adsorption amount (μg) per 1 g of each gas adsorbent powder. The initial concentrations were 300 ppm for propylene oxide and methyl iodide, and 100 ppm for acetic acid, formaldehyde, hydrogen sulfide, xylene, toluene, ammonia, sulfurous acid gas, and nitric acid gas.

ガス吸着性粉体の第1のグループは疎水性のガス吸着性粉体で、その代表が活性炭である。活性炭は、その形状から大別すると粒状活性炭と粉末活性炭の2つに分類できる。本発明においては抄紙法により粉体を紙に担持させるので、平均粒子径が50μm以下の粉末活性炭を使用することが好ましい。一般的に活性炭の原料としては木炭、木材、椰子殻、石炭、亜炭、瀝青炭、ピート等が使用される。使用される原料の違いにより、ガスの吸着量に影響を及ぼす細孔径分布が大きく異なるので、各種ガスへの吸着性能に差が生じてくるのが特徴である。また、特定のガスを対象として吸着することを目的に、前記の粒状若しくは粉末活性炭を化学的に処理したり、銀等の金属類を添着させたりした特殊な機能性活性炭を使用しても良い。   The first group of gas-adsorbing powders are hydrophobic gas-adsorbing powders, typically represented by activated carbon. Activated carbon can be roughly classified into two types: granular activated carbon and powdered activated carbon. In the present invention, since the powder is supported on the paper by the papermaking method, it is preferable to use powdered activated carbon having an average particle diameter of 50 μm or less. Generally, charcoal, wood, coconut shell, coal, lignite, bituminous coal, peat, etc. are used as raw materials for activated carbon. Since the pore size distribution that affects the gas adsorption amount varies greatly depending on the difference in the raw materials used, it is characterized by differences in the adsorption performance to various gases. In addition, for the purpose of adsorbing a specific gas, a special functional activated carbon obtained by chemically treating the granular or powdered activated carbon or impregnating a metal such as silver may be used. .

ガス吸着性粉体の第2のグループは親水性のガス吸着性粉体で、例えば含鉄アルミニウム水和物、アルミノケイ酸亜鉛系鉱物、シリカゲル、シリカアルミナ質ゲル状粘土、ゼオライト、アルミナゲル等の活性炭以外の吸着剤である。これらの吸着剤は親水性であって、水のような極性分子を選択的に吸着するのが特徴である。本発明は、前述した残留燻蒸ガスの除去が主目的である。しかし、同時に収蔵庫内の亜硫酸ガス等の大気汚染物質も除去できれば更に有用なものとなる。また、新築した建物において、建材や家具等から発散するVOC等の汚染ガスも除去できれば、新築やリフォームされた住宅、あるいは保存施設にとって欠くべからざるものとなる。従って本発明においては、両方のグループのガス吸着性粉体を活かした汚染ガス除去紙の提供を目的としたものである。   The second group of gas-adsorbing powders are hydrophilic gas-adsorbing powders such as iron-containing aluminum hydrate, zinc aluminosilicate mineral, silica gel, silica-alumina gel-like clay, zeolite, alumina gel and other activated carbon. It is adsorbent other than. These adsorbents are hydrophilic and are characterized by selectively adsorbing polar molecules such as water. The main object of the present invention is to remove the residual fumigation gas described above. However, it will be more useful if air pollutants such as sulfurous acid gas in the storage can be removed at the same time. In addition, if a contaminated gas such as VOC emanating from building materials and furniture in a newly built building can be removed, it will be indispensable for a newly built or renovated house or storage facility. Accordingly, an object of the present invention is to provide a contaminated gas removing paper utilizing the gas adsorbing powders of both groups.

表1に前記した各種のガス吸着性粉体1gあたりのガス吸着量(μg)を測定して、以下のような4分類に区分して評価した結果を示した。汚染ガスの種類によって基準は異なるが、○以上を汚染ガスの吸着性能があるとして合格と判定した。

○:1500μg/g未満〜1000μg/g以上
△:1000μg/g未満〜500μg/g以上

○:1000μg/g未満〜500μg/g以上
△:500μg/g未満〜200μg/g以上
×:200μg/g未満
Table 1 shows the results of evaluation by dividing the gas adsorption amount (μg) per 1 g of the various gas adsorbing powders described above into the following four categories. Although the standard differs depending on the type of pollutant gas, it was determined that the mark of “◯” or higher is acceptable because it has a pollutant gas adsorption performance.

表1の結果から以下のことがわかった。
(1)ヨウ化メチルや酸化プロピレンを良く吸着する粉体は椰子殻活性炭であり、木質活性炭も両方のガスを吸着するが椰子殻活性炭と比較すると若干劣る。また、シリカゲルは酸化プロピレンを吸着する。
(2)含鉄アルミニウム水和物、アルミノケイ酸亜鉛系鉱物、シリカアルミナ質ゲル状粘土の親水性の吸着剤は、ヨウ化メチルや酸化プロピレンをほとんど吸着しない。
(3)椰子殻活性炭と木質活性炭はキシレンやトルエンを吸着する。含鉄アルミニウム水和物、アルミナケイ酸亜鉛系鉱物、シリカゲル、シリカアルミナ質ゲル状粘土はキシレンとトルエンを少ししか吸着しない。
(4)木質活性炭、椰子殻活性炭、シリカゲルは硫化水素を少ししか吸着しないが、含鉄アルミニウム水和物、アルミナケイ酸亜鉛系鉱物、シリカアルミナ質ゲル状粘土は硫化水素を吸着する。
(5)含鉄アルミニウム水和物、アルミノケイ酸亜鉛系鉱物、シリカゲル、シリカアルミナ質ゲル状粘土、木材パルプ紙は酢酸を吸着する。
以上のことから、ヨウ化メチルや酸化プロピレンといった残留燻蒸ガスを除去するには活性炭を単独で担持させた汚染ガス除去紙で良いことがわかる。しかしながら、前述したVOCや大気汚染ガスをも吸着除去できるものにするには活性炭と親水性の吸着剤を併用する必要性がある。尚、本評価試験においては、暫定的に酢酸や硫化水素といった悪臭ガスは、VOCのカテゴリーとして分類した。
From the results in Table 1, the following was found.
(1) The powder that adsorbs methyl iodide and propylene oxide well is coconut shell activated carbon, and wood activated carbon also adsorbs both gases, but is slightly inferior to coconut shell activated carbon. Silica gel adsorbs propylene oxide.
(2) Hydrophilic adsorbents such as iron-containing aluminum hydrate, zinc aluminosilicate mineral, and silica-alumina gel-like clay hardly adsorb methyl iodide and propylene oxide.
(3) Coconut shell activated carbon and wood activated carbon adsorb xylene and toluene. Iron-containing aluminum hydrate, zinc-alumina silicate mineral, silica gel, and silica-alumina gel-like clay absorb little xylene and toluene.
(4) Wood activated carbon, coconut shell activated carbon, and silica gel absorb little hydrogen sulfide, but iron-containing aluminum hydrate, alumina zinc silicate mineral, and silica alumina gel-like clay adsorb hydrogen sulfide.
(5) Iron-containing aluminum hydrate, zinc aluminosilicate mineral, silica gel, silica-alumina gel clay, and wood pulp paper adsorb acetic acid.
From the above, it can be seen that a polluted gas removing paper carrying activated carbon alone is sufficient to remove residual fumigation gases such as methyl iodide and propylene oxide. However, it is necessary to use activated carbon and a hydrophilic adsorbent in combination in order to make it possible to adsorb and remove the VOC and air pollutant gas described above. In this evaluation test, malodorous gases such as acetic acid and hydrogen sulfide were temporarily classified as a VOC category.

本発明におけるガス吸着性粉体としては、疎水性のガス吸着性粉体と親水性のガス吸着性粉体とを混合して、あるいは組み合わせて使用する。   As the gas adsorbing powder in the present invention, a hydrophobic gas adsorbing powder and a hydrophilic gas adsorbing powder are mixed or used in combination.

疎水性のガス吸着性粉体である活性炭のガス吸着性能はその使用原料によって異なり、かつ細孔径と細孔分布に大きく影響される。平均細孔半径のピークが1.0nm付近に集中している椰子殻活性炭は、平均細孔半径が2.0〜3.5nmに分布している木質活性炭より平均細孔半径が遙かに小さいために、燻蒸ガスやトルエン、キシレン等のVOCに対する吸着性能が優れていることが前述の評価結果からも確認できた。従って本発明で使用する活性炭としては木質活性炭も使用できるが、椰子殻活性炭の方が好ましいものである。加えて、活性炭の平均粒子径は50μm以下の粉末活性炭が好ましい。その理由は、抄紙する際の適性を考慮すると、これよりも平均粒子径が大きいと粒子の凹凸によって抄紙機が損傷しやすくなることと、活性炭の比表面積が小さくなるので汚染ガス吸着性能が低下してくる傾向があり好ましくないからである。また、平均粒子径が小さくなるほど比表面積が増大するのでガス吸着性能の向上効果としては好ましいが、小さくなるにつれてコストが高くなる傾向があるので、平均粒子径としては3〜50μmの範囲のものが好ましい。また、前記した機能性活性炭についても、平均粒子径や価格が適正なものであれば本発明に使用することは一向に差し支えない。   The gas adsorption performance of activated carbon, which is a hydrophobic gas adsorbent powder, varies depending on the raw materials used, and is greatly influenced by the pore diameter and pore distribution. The coconut shell activated carbon in which the peak of the average pore radius is concentrated in the vicinity of 1.0 nm has a much smaller average pore radius than the wood activated carbon in which the average pore radius is distributed in the range of 2.0 to 3.5 nm. Therefore, it has also been confirmed from the above-described evaluation results that the adsorption performance for the VOC such as fumigation gas, toluene and xylene is excellent. Accordingly, wood activated carbon can be used as the activated carbon used in the present invention, but coconut shell activated carbon is preferred. In addition, the activated carbon is preferably powdered activated carbon having an average particle size of 50 μm or less. The reason for this is that, considering the suitability for papermaking, if the average particle size is larger than this, the paper machine tends to be damaged by the irregularities of the particles, and the specific surface area of the activated carbon is reduced, so the pollutant gas adsorption performance is reduced. This is because there is a tendency to come. Moreover, since the specific surface area increases as the average particle size decreases, it is preferable as an effect of improving gas adsorption performance. However, since the cost tends to increase as the average particle size decreases, the average particle size is in the range of 3 to 50 μm. preferable. Also, the above-described functional activated carbon can be used in the present invention as long as the average particle size and price are appropriate.

前述した親水性のガス吸着性粉体としては、シリカゲル、アルミナゲル、シリカアルミナゲル、合成ゼオライト、含鉄アルミニウム水和物、アルミノケイ酸亜鉛系鉱物等の合成無機粉体や、シリカアルミナ質ゲル状粘土、珪藻土、珪藻頁岩、白土、活性白土、天然ゼオライト等の天然の無機粉体を挙げることが出来る。そしてこれらの単独、あるいは1種類以上を併用して使用することができる。しかしながら、それぞれのガス吸着性能を補填するために活性炭の他に数種類の粉体を使用しても一向に構わない。上記した粉体のうち、含鉄アルミニウム水和物とアルミノケイ酸亜鉛系鉱物は、水澤化学工業(株)からそれぞれ「アルフェマイトFP」、「ミズカナイトHP」の商品名で市販されている。また、シリカゲルは富士シリシア化学(株)から「シリカゲルPA−270A」の商品名で市販されている。また、シリカアルミナ質ゲル状粘土は、天然に存在する鉱石の一種でありアロフェン(Allophane)と称されている物である。その性質は化学的に活性であり、吸着力と吸湿力が大きいのが特徴となっている。化学組成は一般に(1〜2)SiO・Al・(4〜6)HOで表され、品川化成(株)から「セカードTS−35」の商品名で市販されている。表1に示したように含鉄アルミニウム水和物、アルミノケイ酸亜鉛系鉱物、シリカアルミナ質ゲル状粘土は、特に硫化水素に対する吸着性能があり、酢酸、ホルムアルデヒド、アンモニア、亜硫酸ガスおよび硝酸ガスに対する吸着性能も良好であるので好適に使用できる。またシリカゲルは、アンモニア、酢酸、ホルムアルデヒド、硝酸ガスに対する吸着性能が優れており、好適に使用できる。 Examples of the hydrophilic gas-adsorbing powder include silica gel, alumina gel, silica alumina gel, synthetic zeolite, iron-containing aluminum hydrate, zinc aluminosilicate mineral, etc., silica alumina gel gel clay And natural inorganic powders such as diatomaceous earth, diatom shale, white clay, activated white clay, and natural zeolite. These can be used alone or in combination of one or more. However, in order to compensate for each gas adsorption performance, it is possible to use several kinds of powders in addition to activated carbon. Among the powders described above, iron-containing aluminum hydrate and zinc aluminosilicate mineral are commercially available from Mizusawa Chemical Industry Co., Ltd. under the trade names “Alphemite FP” and “Mizukanite HP”, respectively. Silica gel is commercially available from Fuji Silysia Chemical Ltd. under the trade name “Silica gel PA-270A”. Silica-alumina gel-like clay is a kind of ore that exists in nature, and is called allophane. Its properties are chemically active, and it is characterized by high adsorption and moisture absorption. The chemical composition is generally represented by (1-2) SiO 2 .Al 2 O 3. (4-6) H 2 O, and is commercially available from Shinagawa Kasei Co., Ltd. under the trade name “Secard TS-35”. As shown in Table 1, iron-containing aluminum hydrates, zinc aluminosilicate minerals, and silica-alumina gel-like clays have adsorption performance particularly for hydrogen sulfide, and adsorption performance for acetic acid, formaldehyde, ammonia, sulfurous acid gas and nitric acid gas. Can also be used favorably. Silica gel has excellent adsorption performance for ammonia, acetic acid, formaldehyde, and nitric acid gas, and can be suitably used.

本発明においては、製紙用繊維を主体とした3層以上の多層抄き合わせ紙の中層に疎水性および/または親水性のガス吸着性粉体を単独若しくは混合して担持させた混抄紙を設けることを基本形とするものである。中層のガス吸着性粉体混抄紙は、単層若しくは2層抄き合わせ紙であっても良いし、製紙用繊維を主体とした薄葉紙を介在させた3層抄き合わせ紙であっても良い。一例を挙げて説明すれば、疎水性のガス吸着性粉体を担持せしめた混抄紙と、親水性のガス吸着性粉体を担持せしめた混抄紙を抄き合わせた2層の抄き合わせ紙、あるいはこの間に製紙用繊維を主体とした薄葉紙を挟んだ3層の抄き合わせ紙とし、この中層の表裏に収蔵品等の汚れを防止するため、製紙用繊維を主体とする薄葉紙を抄き合わせたことを特徴とするものである。製紙用繊維としては、針葉樹晒クラフトパルプ(NBKP)、針葉樹未晒クラフトパルプ(NUKP)、広葉樹晒クラフトパルプ(LBKP)、針葉樹晒サルファイトパルプ(NBSP)、サーモメカニカルパルプ(TMP)等の木材パルプの単独、あるいは混合物を主体とし、これに麻、ケナフ等の非木材パルプ、レーヨン、ビニロン、ポリエチレン、合成パルプ、ポリプロピレン等の化学繊維や合成繊維を混合して使用することができる。また、ガス吸着性粉体の脱落や中層の層間剥離を防ぐため、ポリビニルアルコール繊維のような熱水溶解型繊維やポリプロピレン、ポリエチレン、ポリエステル等の低融点の熱接着性繊維や複合繊維を併用することが出来る。しかしながら、表1で示したように木材パルプが本来具備している酢酸等に対するガス吸着性能を最大限に生かした使用方法が望ましい。   In the present invention, a mixed paper in which a hydrophobic and / or hydrophilic gas-adsorbing powder is carried alone or mixed is provided in the middle layer of three or more layers of laminated paper mainly composed of paper-making fibers. Is the basic form. The middle layer gas adsorbent powder mixed paper may be a single layer or two layer laminated paper, or may be a three layer laminated paper interposing a thin paper mainly composed of papermaking fibers. . For example, a two-layered paper made by combining a mixed paper carrying a hydrophobic gas-adsorbing powder and a mixed paper carrying a hydrophilic gas-adsorbing powder. Or, make a three-layered laminated paper with a thin paper mainly composed of papermaking fiber in between, and make a thin paper mainly composed of papermaking fiber on the front and back of this middle layer to prevent soiling of stored items etc. It is characterized by being combined. Wood pulp such as softwood bleached kraft pulp (NBKP), softwood unbleached kraft pulp (NUKP), hardwood bleached kraft pulp (LBKP), softwood bleached sulfite pulp (NBSP), thermomechanical pulp (TMP), etc. These can be used alone or in a mixture, and non-wood pulp such as hemp and kenaf, and chemical fibers and synthetic fibers such as rayon, vinylon, polyethylene, synthetic pulp, and polypropylene can be mixed and used. Also, in order to prevent the gas-adsorbing powder from falling off or delamination of the middle layer, use hot water-soluble fibers such as polyvinyl alcohol fibers, and low-melting-point heat-adhesive fibers such as polypropylene, polyethylene, and polyester, and composite fibers. I can do it. However, as shown in Table 1, a method of using the gas adsorption performance with respect to acetic acid or the like originally included in the wood pulp is desirable.

本発明では、前記した中層の表裏に抄きあわせる薄葉紙としては、製紙用繊維100質量部に対して、必要に応じて炭酸カルシウムやタルクのようなアルカリ性粉体を0.02〜5.0質量部定着させ、冷水抽出pH値が6.5〜10.0の範囲にあって、坪量が10〜30g/mの中性紙とすることが好ましい。坪量が10g/m未満であるとガス吸着性粉体が脱落する危険性があり、坪量が30g/m以上になるとガス吸着速度が若干低下する傾向があるので好ましくない。さらに中層として使用されるガス吸着性粉体を担持させた混抄紙は、製紙用繊維とガス吸着性粉体の混合物100質量%のうち、ガス吸着性粉体が30〜80質量%を含有する坪量40〜70g/mの紙層とする。また、ガス吸着性粉体を担持させた混抄紙の間に抄き合わされる薄葉紙は特に規制を受けるものはないが、坪量が10〜30g/mの薄葉紙が好ましい。坪量が10g/m未満であると紙層が形成しにくく、坪量が30g/m以上になるとガス吸着速度が若干低下する傾向があるので好ましくない。この様にして得られた3層の抄き合わせ紙は、全坪量が60〜130g/mとなり、4層の場合には100〜200g/m、5層の場合には110〜230g/mの抄き合わせ紙となる。 In the present invention, as a thin paper to be combined on the front and back of the middle layer described above, an alkaline powder such as calcium carbonate or talc is added in an amount of 0.02 to 5.0 mass as necessary with respect to 100 mass parts of papermaking fibers. It is preferable to use a neutral paper having a cold water extraction pH value in the range of 6.5 to 10.0 and a basis weight of 10 to 30 g / m 2 . If the basis weight is less than 10 g / m 2 , there is a risk that the gas-adsorbing powder will fall off, and if the basis weight is 30 g / m 2 or more, the gas adsorption rate tends to decrease slightly, such being undesirable. Furthermore, the mixed paper carrying the gas-adsorbing powder used as the middle layer contains 30 to 80% by mass of the gas-adsorbing powder out of 100% by mass of the mixture of the fiber for papermaking and the gas-adsorbing powder. A paper layer having a basis weight of 40 to 70 g / m 2 is used. Further, there is no particular restriction on the thin paper that is made between the mixed papers carrying the gas-adsorbing powder, but a thin paper having a basis weight of 10 to 30 g / m 2 is preferable. If the basis weight is less than 10 g / m 2, it is difficult to form a paper layer, and if the basis weight is 30 g / m 2 or more, the gas adsorption rate tends to decrease slightly, which is not preferable. Combination papers of three layers obtained in this manner, total basis weight is 60~130g / m 2 in which case it 100 to 200 g / m 2, 5-layer in the case of four layers 110~230g / M 2 of laminated paper.

上記のようにして得られた抄き合わせ紙には、12〜112g/mのガス吸着性粉体が担持された紙になる。この場合、それぞれの混抄紙に担持される疎水性ガス吸着性粉体と親水性ガス吸着性粉体の担持量は12〜56g/mとなる。一般的に汚染ガスの吸着速度と吸着量は、紙表面に点在するガス吸着性粉体の充填密度(表面積)と充填量に深く関係している。疎水性、親水性それぞれのガス吸着性粉体が12g/m未満であると汚染ガスの吸着量が少なくなり、56g/mを越えると吸着速度と吸着量には問題ないが、充填量が多すぎて粉体の歩留まりが一層低下し、生産コストがアップしてしまうので好ましくない。そのために3層抄き合わせ紙の中に担持させる疎水性および/または親水性のガス吸着性粉体の含有量は30〜80質量%の範囲であることが好ましい。 The laminated paper obtained as described above is a paper on which 12 to 112 g / m 2 of gas adsorbing powder is supported. In this case, the carrying amount of the hydrophobic gas adsorbing powder and the hydrophilic gas adsorbing powder carried on each mixed paper is 12 to 56 g / m 2 . In general, the adsorption speed and adsorption amount of polluted gas are closely related to the packing density (surface area) and the packing amount of gas adsorbing powder scattered on the paper surface. If the hydrophobic and hydrophilic gas adsorbent powders are less than 12 g / m 2 , the adsorbed amount of the pollutant gas decreases, and if it exceeds 56 g / m 2 , there is no problem in the adsorbing speed and adsorbed amount. This is not preferable because the powder yield is further reduced and the production cost is increased. Therefore, the content of the hydrophobic and / or hydrophilic gas-adsorbing powder to be carried in the three-layer laminated paper is preferably in the range of 30 to 80% by mass.

本発明においては、疎水性および/または親水性のガス吸着性粉体を単独若しくは混合して担持させた混抄紙を組み合わせて使用する。この場合、主として残留した薫蒸ガスの除去が目的の場合には疎水性ガス吸着性粉体を担持した混抄紙の割合を高めたものとし、VOCや大気汚染ガスの除去と両用する目的の場合には疎水性ガス吸着性粉体と親水性ガス吸着性粉体を担持した混抄紙の割合を1:1とし、VOCや大気汚染ガスの除去が主目的の場合には、親水性ガス吸着性粉体を担持した混抄紙の割合を高めたものとしたものが好適に使用される。このように本発明においては、疎水性ガス吸着性粉体および/または親水性のガス吸着性粉体を単独若しくは混合して担持させた混抄紙の割合を任意に変化させることにより、さらにはガス吸着性粉体の種類を必要に応じて選択し、あるいは組み合わせることで各種の汚染ガスに対して、最適の組み合わせの汚染ガス除去紙を得ることができる。   In the present invention, a mixed paper carrying hydrophobic and / or hydrophilic gas-adsorbing powders alone or mixed and used is used. In this case, if the purpose is mainly to remove the remaining fumigation gas, the ratio of the mixed paper carrying the hydrophobic gas-adsorbing powder is increased, and the purpose is to use both for removal of VOC and air pollutant gas. In the case where the ratio of mixed paper carrying hydrophobic gas-adsorbing powder and hydrophilic gas-adsorbing powder is 1: 1, and the main purpose is removal of VOC and air pollutant gas, hydrophilic gas adsorbing property What increased the ratio of the mixed paper which carry | supported powder is used suitably. As described above, in the present invention, the ratio of the mixed paper on which the hydrophobic gas-adsorbing powder and / or the hydrophilic gas-adsorbing powder is carried alone or mixed is arbitrarily changed. By selecting or combining the types of adsorbent powder as necessary, it is possible to obtain the optimum combination of pollutant gas removal papers for various pollutant gases.

本発明においては、上記したように疎水性および/または親水性のガス吸着性粉体を単独若しくは混合して担持させた混抄紙を組み合わせて使用するが、この際に、抄紙機の流れ方向の両端部に疎水性および親水性のガス吸着性粉体の単独若しくは混合物を担持しない部分を帯状に設けることが必要である。このようにしないと、両端部から疎水性および/または親水性ガス吸着性粉体の単独若しくは混合物がこぼれ落ち、周囲を汚染するという問題が発生する。   In the present invention, as described above, a mixed paper carrying a hydrophobic and / or hydrophilic gas-adsorbing powder alone or mixed and used is used. In this case, in the flow direction of the paper machine, It is necessary to provide a belt-like portion that does not carry a single or mixture of hydrophobic and hydrophilic gas-adsorbing powders at both ends. If this is not done, there will be a problem that the hydrophobic and / or hydrophilic gas-adsorbing powder alone or a mixture spills from both ends and contaminates the surroundings.

また、本発明による汚染ガス除去紙は、使用に際して各種の大きさや形状に加工されて使用される。そのために疎水性および/または親水性ガス吸着性粉体を設けない部分は、抄紙機の流れ方向の両端部のみならず縦方向や横方向、さらには斜め方向にも設けることによって、加工の自由度が増加し、任意の形状や大きさに加工することが可能となるので好ましい。   Further, the pollutant gas removing paper according to the present invention is used after being processed into various sizes and shapes. For this reason, the parts that are not provided with hydrophobic and / or hydrophilic gas-adsorbing powder are provided not only at both ends in the flow direction of the paper machine, but also in the vertical direction, the horizontal direction, and also in the oblique direction. The degree increases, and it is possible to process into an arbitrary shape and size, which is preferable.

疎水性および/または親水性ガス吸着性粉体の単独若しくは混合物を担持しない部分の形状は、直線であっても、曲線であっても、あるいは連続的なパターンであっても構わないし、抄紙機の流れ方向に対して横方向に不連続のパターン状に設けても一向に差し支えない。   The shape of the portion that does not carry the hydrophobic and / or hydrophilic gas adsorbing powder alone or as a mixture may be a straight line, a curved line, or a continuous pattern. Even if it is provided in a discontinuous pattern shape in the transverse direction with respect to the flow direction, there is no problem.

本発明における疎水性および/または親水性ガス吸着性粉体の単独若しくは混合物を担持しない部分の幅については、疎水性および/または親水性ガス吸着性粉体の単独若しくは混合物が外部にこぼれ落ちることのない強度を有していればどのような幅であっても構わないが、後で各種の大きさや形状に加工する際にハサミやカッターなどで切断し易い程度の幅を有していることが好ましく、通常は3〜15mm程度であることが好ましい。3mm以下であると、後加工の際に疎水性および/または親水性ガス吸着性粉体の単独若しくは混合物が含まれている部分を傷つけてしまう危険性があり好ましくない。また15mm以上あると後加工の際の作業性には問題ないが、全面積当たりの疎水性および/または親水性ガス吸着性粉体の単独若しくは混合物を含有する面積が狭くなるので好ましくない。また、抄紙機の流れ方向の両端部においては、抄紙時の耳部分にもあたるために通常は巻き取りとして仕上げる際にカットされる部分でもあるため、5〜25mmであることが好ましい。   With respect to the width of the portion not supporting the hydrophobic and / or hydrophilic gas-adsorbing powder alone or in the mixture in the present invention, the hydrophobic or / and hydrophilic gas-adsorbing powder alone or the mixture may spill outside. Any width can be used as long as it has no strength, but it has a width that can be easily cut with scissors or a cutter when processing into various sizes and shapes later. In general, it is preferably about 3 to 15 mm. If it is 3 mm or less, there is a risk of damaging a part containing a hydrophobic and / or hydrophilic gas-adsorbing powder alone or in a mixture during post-processing, which is not preferable. On the other hand, when the thickness is 15 mm or more, there is no problem in workability during post-processing, but the area containing the hydrophobic or / and hydrophilic gas-adsorbing powder alone or mixture per total area is not preferable. Further, both ends in the flow direction of the paper machine are also cut portions when finishing as a take-up because they hit the ears at the time of paper making.

疎水性および/または親水性ガス吸着性粉体の単独若しくは混合物を担持しない部分を作成するには、透き入れ紙を製造する際の手法を適用することが可能であり、以下のような方法が考えられるが、これに限定されるものではない。   In order to create a portion that does not carry a hydrophobic and / or hydrophilic gas-adsorbing powder alone or as a mixture, it is possible to apply a technique for producing a transparent paper. Though conceivable, it is not limited to this.

円網抄紙機における円網シリンダーの上網の一部を塞ぐ方法。例えば、疎水性および/または親水性ガス吸着性粉体の単独若しくは混合物を担持しない部分のパターンを、上網に針金、金属、樹脂、紙、プラスチック等で作成し、これを金属やプラスチックの細線で取り付ける方法、あるいはハンダ付けや接着剤を使用することで取り付ける方法がある。また上網に直接塗料や樹脂を塗工し疎水性および/または親水性ガス吸着性粉体の単独若しくは混合物を担持しない部分のパターンを描く方法がある。また感光性樹脂を使用しても良いし、抄紙網にヒートシールタイプなどのテープを貼り付ける方法もある。また、抄紙網にパターンを糸で形成する方法もある。   A method of closing a part of the upper net of a circular cylinder in a circular paper machine. For example, a pattern of a portion that does not carry a single or mixture of hydrophobic and / or hydrophilic gas-adsorbing powder is made of wire, metal, resin, paper, plastic, etc. on the upper net, and this is made of fine wires of metal or plastic There is a method of attaching, or a method of attaching by using soldering or an adhesive. Further, there is a method in which a coating or resin is directly applied to the upper net to draw a pattern of a portion not supporting a hydrophobic and / or hydrophilic gas-adsorbing powder alone or a mixture. In addition, a photosensitive resin may be used, and there is a method of sticking a heat seal type tape on a papermaking net. There is also a method of forming a pattern with a thread on a papermaking net.

その他の方法として、抄紙網自体にパターンに沿った凹凸を形成させる方法や、原料がのった抄紙網上にて連続的に水を滴下させ、あるいはスプレー装置などで水を散布することで疎水性および/または親水性ガス吸着性粉体の単独若しくは混合物を担持しない部分のパターンを形成させることが可能である。   Other methods include forming the unevenness along the pattern on the papermaking net itself, dropping water continuously on the papermaking net with the raw material, or spraying water with a spray device etc. It is possible to form a pattern of a portion that does not carry a single or mixture of hydrophilic and / or hydrophilic gas-adsorbing powder.

また、疎水性および/または親水性ガス吸着性粉体の単独若しくは混合物を担持しない部分の一部、あるいは全部にミシン目を入れると、できあがった汚染ガス除去紙を各種の大きさや形状に加工する際にハサミやカッターを使用する手間が省け、容易に必要な大きさや形状の汚染ガス除去紙を得ることができるので好ましい。   In addition, when the perforation is made in a part or all of the part that does not carry the hydrophobic and / or hydrophilic gas adsorbing powder alone or in the mixture, the resulting contaminated gas removing paper is processed into various sizes and shapes. In this case, it is preferable because it eliminates the trouble of using scissors and a cutter, and can easily obtain a contaminated gas removing paper having a required size and shape.

ミシン目を作成するには、一般的なミシン目を作成する装置が自由に適用でき、抄紙機と連動したオンマシンでも、あるいは抄紙機とは別にオフマシンで加工しても一向に差し支えない。また、ミシン目の形状やピッチは、できあがった汚染ガス除去紙を任意の大きさや形状に加工することが可能であれば、どのようなものでもかまわない。   To create a perforation, a general perforation device can be freely applied, and it can be used either on-machine in conjunction with a paper machine or off-machine separately from the paper machine. The perforation shape and pitch may be any as long as the finished polluted gas removing paper can be processed into an arbitrary size and shape.

Table 2 shows the results of confirming the quality of the gas adsorption performance of the laminated paper obtained in Examples 1 to 16 and Comparative Examples 1 to 6. In the table, Examples 1 to 16 indicate Examples 1 to 16, and Ratios 1 to 6 indicate Comparative Examples 1 to 6. Evaluation was performed as follows. Samples for evaluation were prepared by cutting the contaminated gas removing papers of Examples 1 to 16 and Comparative Examples 1 to 6 into 5 × 5 cm squares. These samples were pretreated by leaving them under conditions of 23 ° C. and 50% relative humidity for 24 hours, then degassing these samples in a Tedlar bag, and adding 2 liters of various gases adjusted to known concentrations. Immediately after injection, the concentration was measured using a detector tube (manufactured by Gastec Co., Ltd.) under the condition of a temperature of 23 ° C., and this was taken as the initial concentration. After leaving the temperature at 23 ° C. for 5 hours, the residual gas concentration in the Tedlar bag was measured again. The gas adsorption amount of each sample was converted as the adsorption amount (μg / g) per 1 g of each sample by subtracting the residual gas concentration from the initial concentration. The initial concentrations were 300 ppm for propylene oxide and methyl iodide, and 100 ppm for acetic acid, formaldehyde, hydrogen sulfide, xylene, toluene, ammonia, sulfurous acid gas, and nitric acid gas. In the table, the criteria of ◎ (adsorbs well), ○ (adsorbs), △ (slightly adsorbs), × (not adsorbs) are classified into the following four categories, Although the standard of the mark differs depending on the type, the marks ◎ and ◯ were determined to have adsorption performance.
A: Adsorbs polluting gas well.
○: Adsorbed.
Δ: Slightly adsorbed.
X: Not adsorbed.
About propylene oxide: A: 7500 μg / g or more
○: Less than 7500 μg / g to 2000 μg / g or more
Δ: Less than 2000 μg / g to 500 μg / g or more

表2から以下のことがわかる。
(1)実施例1〜16は、各種の汚染ガスに対する吸着性能が認められる。
(2)比較例1は、活性炭量が不足しているため、燻蒸ガスである酸化プロピレンとヨウ化メチルに対する吸着性能が劣る。
(3)比較例2〜5は、親水性ガス吸着性粉体の量が不足しているために、VOCや大気汚染ガスに対する吸着性能が劣る。
(4)比較例6は、活性炭を含有していないため、燻蒸ガスである酸化プロピレンとヨウ化メチルに対する吸着性能が劣る。
以上の結果から、本発明の実施例1〜16は、燻蒸ガスの残留ガスの除去紙およびVOCや大気汚染ガス除去紙として兼用できるものであることがわかる。
Table 2 shows the following.
(1) In Examples 1 to 16, adsorption performance for various polluted gases is recognized.
(2) Since the amount of activated carbon is short in Comparative Example 1, the adsorption performance with respect to the fumigation gases propylene oxide and methyl iodide is inferior.
(3) Since Comparative Examples 2 to 5 lack the amount of the hydrophilic gas adsorbing powder, the adsorption performance for VOC and air polluted gas is inferior.
(4) Since the comparative example 6 does not contain activated carbon, the adsorption performance with respect to fumigation gas propylene oxide and methyl iodide is inferior.
From the above results, it can be seen that Examples 1 to 16 of the present invention can also be used as a residual gas removal paper for fumigation gas and a VOC or air pollution gas removal paper.

某美術館の収蔵庫(容積が480m)を酸化プロピレン(48g/m)とアルゴンの混合気体を使用して48時間燻蒸した後、庫内空気の換気を強制的に4日間行い、換気が終了した時点での酸化プロピレン濃度を0ppmにした。次に、換気を行わないで24時間放置した後で酸化プロピレンの濃度を再測定したところ、10ppmに再上昇していた。そこで実施例1で得られた汚染ガス除去紙(坪量が90g/m)を庫内の壁面や収納棚に設置(使用量:A/V=0.1m−1)して24時間換気を行わずに放置した後で酸化プロピレンの濃度を測定したところ0ppmになっていた。さらに72時間換気しないで放置したが、酸化プロピレン濃度が再上昇することはなく、燻蒸ガスに対して除去効果があることが確認された。
The following describes typical use examples and their effects.
The fumigation of the Sakai Art Museum warehouse (volume 480 m 3 ) was fumigated for 48 hours using a mixed gas of propylene oxide (48 g / m 3 ) and argon, and then the air in the warehouse was forcibly ventilated for 4 days. The propylene oxide concentration at the time of completion was set to 0 ppm. Next, after standing for 24 hours without ventilation, the concentration of propylene oxide was re-measured and found to rise again to 10 ppm. Therefore, the polluted gas removing paper (basis weight is 90 g / m 2 ) obtained in Example 1 is installed on the wall surface or storage shelf in the warehouse (use amount: A / V = 0.1 m −1 ) and ventilated for 24 hours. When the concentration of propylene oxide was measured after leaving without performing the process, it was 0 ppm. Further, it was left unventilated for 72 hours, but the propylene oxide concentration did not rise again, and it was confirmed that there was a removal effect on the fumigation gas.

某歴史館の特別収蔵庫(容積が394m)を、ヨウ化メチル(40g/m)の気体で24時間燻蒸した後、庫内空気の換気を強制的に24時間行い、換気が終了した時点でのヨウ化メチルの濃度を1ppm以下にした。次いで3時間毎に換気の運転と停止を24時間繰り返した後、ヨウ化メチルの濃度を測定したところ30ppmに再上昇していた。そこで実施例5で得られた汚染ガス除去紙(坪量が90g/m)を庫内の壁面や収納棚に設置(使用量:A/V=0.1m−1)して、再び3時間毎に換気運転と停止を24時間繰り返した後、ヨウ化メチルの濃度を測定したところ、換気停止時のヨウ化メチル濃度が再上昇することがなく、明らかに燻蒸ガスに対する除去効果があることが確認された。 After the fumigation of a special warehouse (volume: 394 m 3 ) of the Sakai History Museum with fumigation of methyl iodide (40 g / m 3 ) for 24 hours, the air in the warehouse was forcibly ventilated for 24 hours, and the ventilation was completed. The concentration of methyl iodide at the time was 1 ppm or less. Then, after repeating the operation and stoppage of ventilation every 3 hours for 24 hours, the concentration of methyl iodide was measured and found to rise again to 30 ppm. Therefore, the polluted gas removing paper (basis weight is 90 g / m 2 ) obtained in Example 5 is installed on the wall surface or storage shelf in the warehouse (use amount: A / V = 0.1 m −1 ), and 3 again. After repeating the ventilation operation and stop every hour for 24 hours, the concentration of methyl iodide was measured, and the methyl iodide concentration at the time of ventilation stop did not rise again, and it clearly has a removal effect on fumigation gas Was confirmed.
