Abstract
【解決手段】本発明では、無機繊維を含む抄造シート材であって、前記無機繊維が塊状に凝集された塊状凝集繊維を含んでいることを特徴とする抄造シート材が提供される。
【選択図】図1
Description
無機繊維が塊状に凝集された塊状凝集繊維を含む、無機繊維の原料繊維を提供するステップと、
前記原料繊維を開繊するステップと、
開繊された繊維からスラリを調製するステップと、
前記スラリを用いて、所望の形状の成形体を形成するステップと、
得られた成形体を圧縮乾燥して、前記無機繊維を含むシート材を得るステップと、
を有することを特徴とするシート材の製造方法が提供される。
前記保持シール材は、前述の抄造シート材で構成されることを特徴とする排気ガス処理装置が提供される。
まず最初に、以下の手順により、塊状凝集繊維の導入源となるニードリングシート材を作製した。
次に以下の方法により、塊状凝集繊維を含む抄造シート材を製作した。
塊状凝集繊維割合P(%)=
(回収した塊状凝集繊維の重量(g))/(初期サンプル重量(g))×100 (1)
により、塊状凝集繊維割合Pを求めた。
次に、前述の方法で製作した各シート材の保持力を評価するため、面圧評価試験を行った。なお、「面圧」とは、シート材が圧縮力を受けた際に、その圧縮力とは反対の方向に生じる、シート材の反発力を意味する。通常、保持シール材は、排気ガス処理体の外表面から圧縮力(外向きの力)を受けているが、これにより、保持シール材に「面圧」が生じ、保持シール材が排気ガス処理体を保持することができる。従って、「面圧」は、シート材が排気ガス処理体を保持するときの保持力を評価する指標として使用することができる。
各シート材に対して得られた面圧測定結果を表1および図7に示す。これらの結果から、シート材に含まれる塊状凝集繊維の割合が多いほど、面圧が向上することがわかる。特に、塊状凝集繊維の割合が20.3%の実施例1のシート材は、抄造法で製作したにも関わらず、ニードリング処理法により製作された比較例2に係るニードリングシート材とほぼ同等の面圧値を示すことがわかった。
