Description
添着量[%]=炭酸カリウムの添加質量[g]/添着前の活性炭質量[g]×100
また、この発明の実施に当たり、前述したカバー材と活性炭粒子とは、ホットメルト樹脂からなる樹脂凝集部を介して接着され、前述した難燃剤と炭酸カリウムを添着した活性炭粒子とは離間配置されていることが好適である。
始めに、この評価試験では、既に説明した図1の構造のフィルタを種々の材料条件で作製した。まず、カバー材11に被着するための難燃剤を含有するバインダーとして、先に述べた「HF−1」の難燃性規格を期待し得る市販のリン系難燃剤液(難溶性のポリリン酸アンモニウムが固形分として54質量%含有する水分散液)37重量部と、アクリル系樹脂エマルジョン型接着剤(固形分45質量%の水分散液)4.4重量部と、周知の増粘剤0.4重量部と、水58.2重量部とを混合調製した。
次に、上記各フィルタ試料について、前述した難燃性を試験評価した結果について説明する。先に述べたとおり、本発明に係るフィルタは、その厚さ方向に処理すべき空気を通過させることで使用するのが好ましいことから、非特許文献1に規定された水平燃焼試験により評価を実施した。この水平燃焼試験では、所定の高さに試験片を配置しておくことができる支持用金網を用い、この金網の下方に175±25mmの距離で脱脂綿(標識綿と称される)を配置しておく。この金網に、長さ150±1mm、幅50±1mmの短冊状に裁断され、しかも長さ方向の一方の端部から、25mm、60mm及び125mmの各位置に合計3つの標線を予め書き込んだ試験片を載置する。燃焼試験は、試験片を水平に載置した状態で上述した端部に金網の下方から炎を60±1秒間当てたのち、炎を試験片から離す。この時点から計時し、
[a]炎が消えた(残炎)時間
[b]炎と赤熱が消えた(残じん)時間
[c]炎又は赤熱の前線が125mm標線に達した時間、若しくは試験片が125mm標線の手前で燃焼又は赤熱が止まった時間
の3種類の時間を記録する。このような評価試験を5回実施した結果に応じて、夫々の難燃性基準条件は、下記の表2に示すような「94HF−1」若しくは「94HF−2」の2つに分類評価される。
この実施例では、表1で説明した4種類のフィルタを30mmφの円盤状に裁断し、円筒状ガラス製測定ホルダーにセットした。この測定ホルダーに対して、市販のオゾン発生機でオゾン濃度2.7ppm、セットされたフィルタ表面での面風速17cm/秒、相対湿度35%の条件によりオゾン雰囲気を連続8時間流し、ホルダーの流入側および流出側の各オゾン濃度を経時的に測定した。この際、オゾン濃度の測定には、『MODEL1200』(ダイレック(株)製,商品名)を用い、オゾン分解性能は、下記の式1からオゾン除去率(%)として算出した。尚、試験開始後10分でのオゾン除去率を初期効率とした。
この実施例では、ガス吸着フィルタ試験法として「DIN 71460−II」に準拠し、VOCをトルエンとした性能評価を実施した。この性能評価では、表1の4種類のフィルタを折高さ60mmのプリーツフィルタとし、周知の枠材によって間口面積;縦56mm×横112mm×高さ60mm、間口面積当たりの濾材面積;1880cm2の寸法条件でユニットを作製し、定格風量1.8m/秒、流入側トルエン濃度80ppm一定の条件下でトルエンガスを流し続け、経時的にユニットの流出側のトルエン濃度を脱臭フィルタ用ガス除去性能測定装置にて測定した。このVOC除去の性能評価は、流出側におけるトルエンの濃度が流入側の95%になった破過点(効率としては5%にまで低下した時点)までのトルエン吸着容量を間口面積当たりの値として(g/m2)の単位で求めた。さらに、この試験においては、試験開始後、1分後の測定値を初期効率として算出した。

15:(ホットメルト樹脂からなる)連結部、
17:(ホットメルト樹脂からなる)樹脂凝集部。
