実条件備品試験(RCFT)
本試験は、モノリスまたはディーゼル微粒子トラップを備えた汚染制御装置の一般使用中の実際の条件をモデル化して、これらのモデル化された使用条件下での実装材料が出す圧力を測定するものである。RCFT方法は、自動汚染制御装置の材料の側面(Material Aspects in Automotive Pollution control devices)、ハンスボーデ(Hans Bode)編、ウィリー−VCH(Wiley−VCH)2002、206〜208頁に詳細が記載されている。
熱振動試験を用いて、本発明による実装マットが、ディーゼルエンジン用低温汚染制御装置の実装マットとして好適かどうかさらに評価した。熱振動試験には、排気ガスを金属ケース中に実装マットを実装した汚染制御装置要素(以降、試験組立品と呼ぶ)に通過させ、同時に、コンバータ組立品に、加速耐久試験として作用するのに十分な機械的振動を与えた。

2)モノリスと金属筐体間に円柱状に配置された以下の実施例および比較例に記載した実装マット、および
3)内径が約4.88インチ(12.4cm)の409ステンレス鋼を含む円柱状缶形筐体。
循環圧縮試験の試験装置は以下のものより構成されていた。
a)下部固定部分と、「クロスヘッド速度」と定義されるレートで垂直方向に下部部分から離れて可動する上部部分とを含み、30kNまでの力を測定可能な荷重計(MTS(商標)型番アライアンス(Alliance)RT/30、ノースカロライナ州ケアリーのマテリアルテストシステムズ(Material Test Systems,Cary,North carolina))を備えた市販の試験機器(引張り試験機として一般的に知られている)、
b)機器の固定下部部分に垂直に取り付けられた第1の水晶管(直径50.8mm×長さ20cm)、
c)機器の上部部分の荷重計に垂直に取り付けられた第2の水晶管(直径50.8mm×長さ20cm)、
d)試験組立品と接触する、上部水晶管を通して延在している熱電対、
e)互いに最も近い2本の水晶管の部分を密着して囲むように配置された管形孔を有するレンガライニングを有する電気的に加熱されたオーブン。
a)試験試料を支持する大きな下部水晶ディスク(厚さ20.0mm、直径75mm)、
b)直径約2インチ(51mm)の試験される実装マットの秤量済みディスクを含む試験される実装マットの試験試料、
c)試験試料の上に位置する小さな上部水晶ディスク(厚さ12.5mm、直径51mm)。
1)ギャップ1−2枚の水晶ディスク間の第1の短い距離、
2)ギャップ2−2枚の水晶ディスク間の第2の長い距離。
平均直径約9μm、長さ2.54cmのS−2ガラスファイバー40リットルをアドバンスドガラスファイバーヤーンズLLC(Advanced Glassfiber Yarns LLC)(AGY)から入手した。ファイバーは実質的にショットフリーであった。
E−ガラスファイバー(チョップドガラスストランド、直径9μm、長さ1インチ(25.4mm)までチョップされたもの、アドバンスドガラスファイバーヤーンズLLC(Advanced Glassfiber Yarns LLC)(AGY)(米国サウスカロライナ州のエーケン(Aiken, SC/USA))より入手可能)を用いた以外は、実施例1に記載された方法により、実施例2を作成した。実施例2のマットの組成は表1にまとめてある。
直径約10μm、長さ36mmまでチョップドされたセイント−ゴバインベトロテックスドイチュランド(Saint−Gobain Vetrotex)より入手したR−ガラスファイバー(60%SiO2、25%Al2O3、9%CaOおよび6%MgO)を実施例1に記載した方法によりウェブへと処理した。実施例4のマットの組成は表1にまとめてある。
2つの別個に作成した層を併せてラミネートすることにより2層のマットを作成した。第1の層はR−ガラスから構成されていた。第2の層はE−ガラスから構成されていた。2層をニードルボンディングにより併せた。このやり方で形成された実装マットは異なる組成のガラスの2つの別個の層を有していた。実施例4の2層マットの組成は表1にまとめてある。

比較例2(C2)は、バージニア州アルタヴィスタのBGFインダストリーズ(BGF industries、Altvista,Virginia)よりシルコソフト(Silcosoft)(商標)という名称で市販されているシリカファイバーでできた不織のバインダーを含まないファイバーから構成されていた。マット中のファイバーの平均直径は9ミクロンである。
比較例3(C3)は、市販の膨張性汚染制御装置実装マットから構成されていた。約55%の未膨張の蛭石、約37%のファイバーおよび約8%の有機バインダーとを含んでいる。ファイバーは、直径約2〜3ミクロン、長さが0.5インチ以下の溶融形成されたアモルファスショット含有のアルミナ/シリカファイバーである。
比較例4(C4)は、市販の還元蛭石膨張性汚染制御装置実装マットから構成されていた。約37%の未膨張の蛭石、約54%のファイバーおよび約9%の有機バインダーとを含んでいた。ファイバーは比較例3と同じであった。
比較例5(C5)は、ジョージア州オーガスタのサーマルセラミクス(Thermal Ceramics、Augusta,Georgia)よりカオウールバルクファイバー(Kaowool Bulk Fibers)として入手可能な溶融形成されたショット含有アルミナシリケートファイバーから作成された湿式マットから構成されていた。ファイバーの直径は2〜3ミクロン、長さは約0.5インチである。
