Abstract
Description
本出願は2014年2月21日に出願された米国仮特許出願No.61/942,708の優先権を主張するものであり、これは本明細書に完全に記載されているかのように本明細書に援用される。
・最終製品の非常に大きいLWAFLによる、最終製品のより大きな靭性。
・必要とされる濾水度目標に到達させるための総叩解エネルギーの低減
・繊維コストの削減
・セメント粒子の保持時間の増加
1.未漂白の軟材及び硬材のEscher Wyss(E−W)叩解
2.ラボスケール、試験条件T1及びT5、8%の総繊維含量で製造されたセメント板
○繊維長(SUNY ESFで試験)
・未叩解NBSK、742CSF −2.60mm
・483CSFまで叩解した100%NBSK E−W −2.08mm
・475CSFまで共叩解した6%SEPF、94%未叩解NBSK −2.33mm
LW=.SIGMA.niLi 2/.SIGMA.niLi
に従って計算される。ここでiはカテゴリー(またはビン)番号(例えば、1、2、…N)を指し、niはi番目のカテゴリー中の繊維数を指し、Liはi番目のカテゴリー中の輪郭長−ヒストグラムの階級中央の長さを指す。
LW(前)−LW(後)/LW(前)
長さ加重微細繊維の%=l00×SIGMA.niLi/LT
に従って計算される。ここで、nは0.2mm未満の長さを有する繊維の数を指し、Liは微細繊維の階級中央の長さを指し、LTは総繊維長を指す。
逆の指示がない限り、本明細書に記載されている数値パラメーターは、本発明によって得ることが求められている望ましい特性によって変化し得る近似値である。少なくとも、そして請求項の範囲に対する均等論の適用を制限しようとすることなしに、報告されている有効数字の数を踏まえて、及び通常の端数処理方法を適用することによって、それぞれの数値パラメーターを少なくとも解釈するべきである。
