Abstract
基材に多量のイオン交換樹脂粉末を固着することによりイオン性ガス状汚染物質の除去性能を向上させつつもイオン交換樹脂粉末が脱落し難く、且つ圧力損失が小さいケミカルフィルタの製造方法を提供すること。
【解決手段】
本発明のケミカルフィルタの製造方法は、繊維質ペーパーにイオン交換樹脂粉末と接着剤との混合スラリーを塗布して前記繊維質ペーパーの内部及び表面に前記イオン交換樹脂粉末が固着されたイオン交換樹脂粉末塗布ペーパーを得、該イオン交換樹脂粉末塗布ペーパーを用いてコルゲート状ハニカム構造のケミカルフィルタを形成するものである。上記方法においては、イオン交換樹脂粉末の平均粒径が1〜150μmであることが好ましい。また、上記方法においては、イオン交換樹脂粉末のイオン交換容量が1〜10meq/gであることが好ましい。
【選択図】 なし
Description
平均粒径が20μmで、イオン交換容量が5.0meq/gの強酸性陽イオン交換樹脂粉末(三菱化学株式会社製ダイヤイオン)と、接着剤として用いるシリカゾルとを、固形分の重量比が8:2となるように混合し、固形分濃度(スラリー濃度)40重量%の混合スラリー11を調製した。
(コルゲート状ハニカム構造のケミカルフィルタの作製)
シリカ・アルミナ繊維(平均繊維径5μm、平均繊維長20mm)からなる繊維間空隙率が90%、厚み(図4中、符号t)が0.2mmの平坦状の繊維質ペーパー2の上面に、上記混合スラリー11をロールコータ22を用いて塗布し、さらに乾燥機23で80℃で乾燥させて、平坦状の繊維質ペーパー2の内部及び上面にイオン交換樹脂粉末が固着された平坦状のイオン交換樹脂粉末片面塗布ペーパー3aを巻き取った(図1)。次に該片面塗布ペーパー3aを上記塗布面が下面になるようにセットした後、塗布面が形成されていない上面について、上記と同様に混合スラリー11を塗布し乾燥させて、平坦状の繊維質ペーパーの内部及び上下両面にイオン交換樹脂粉末が固着された平坦状のイオン交換樹脂粉末両面塗布ペーパー3bを巻き取った(図2)。
(ケミカルフィルタの作製)
上記コルゲート状ハニカム構造のケミカルフィルタを、縦100mm×横100mm×厚さ70mmになるようにカットし、これをアルミニウム製の枠材に嵌め込んだ。
(性能の測定)
上記ケミカルフィルタを用い、下記条件でアンモニアの除去率の経時的変化及びケミカルフィルタの寿命を測定した。なお、実際のクリーンルームで問題となるアンモニア濃度は数wtppb(質量十億分率)であるが、加速試験とするためにアンモニア濃度を200wtppbにした。結果を図5に示す。ケミカルフィルタの寿命は1400時間であった。なお、ケミカルフィルタの寿命はアンモニアの除去率が90%まで低下した時点における時間とした。また、この条件でケミカルフィルタの圧力損失を測定したところ、35Paであった。結果を表1に示す。
・通気ガスの組成 :アンモニアを200wtppb含む空気
・通気ガスの温度及び湿度:23℃、50%RH
・除去対象ガス :アンモニア
・通気風速 :0.5m/s
・ケミカルフィルタの厚み:70mm
