1.測定方法
以下では、例で実施される測定方法について説明する。
生成物の粒径分布は、Fraunhofer光散乱近似を用いて、Malvern Mastersizer 2000 Laser Diffraction System(Malvern Instruments Plc.,Great Britain)を用いて測定した。当業者に知られている方法および器具は、充填剤および他の粒状材料の粒径を決定するために一般的に使用される。
生成物の粒径分布は、Fraunhofer光散乱近似を用いて、Malvern Mastersizer 2000 Laser Diffraction System(Malvern Instruments Plc.,Great Britain)を用いて測定した。当業者に知られている方法および器具は、充填剤および他の粒状材料の粒径を決定するために一般的に使用される。
粒径分布データをxy散布図に表示し、これに応じてデータをx列およびy列に配置する一方で、サイズデータをx列に入れ、頻度データをy列に配置した。最大高さ(ym)は、粒径分布曲線を頻度データポイントで選別することによって決定した。次いで対応のx値は、最大高さにおけるピーク位置(xm)として定義された。最大ピーク高さを2で割ることにより、最大高半値が得られた(ym0.5)。
ハンドシートの充填剤含有量は、570℃に加熱したマッフル炉内で乾燥したハンドシートの4分の1を燃焼させることによって決定した。燃焼が完了した後、残渣をデシケーター中に移し、冷却させた。室温に達したときに、残渣の重量を測定し、この質量を乾燥した4分の1のハンドシートの最初に測定した重量に関連させた。
破断長さおよび引張エネルギーはEN ISO 1924−2に従って決定され、内部結合はDIN 54516に従って決定される。
充填剤材料1(P1):Omya AG,Switzerlandから市販されている、分散されていない偏三角面体沈降炭酸カルシウム(d50=4.3μm、Malvern Mastersizer 2000で測定)。
[例1]<凝集添加剤のストック溶液の調製>
FA1のストック溶液は、FA1を23℃の温度の水道水に攪拌しながら添加することによって調製した。FA1が完全に溶解するまで攪拌を60分間続けた。FA1は、FA1溶液の総重量に基づいて4重量%のFA1含有量を有する溶液が得られるような量で添加された。
第1の水性懸濁液S1は、下記表1に示すFA1ストック溶液の量を、室温で攪拌しながら第1の充填剤材料の溶液に添加することによって調製した。凝集した充填剤粒子の最終水性懸濁液SM中の0.5pph(乾燥顔料に対して100部当たりの部)の全体的なFA1含有量を得るために、FA1の量を選択した。
下記表3に示す第1の充填剤材料および第2の充填剤材料を、第1の充填剤材料を室温で攪拌しながら第2の充填剤材料に添加することによって混合した。得られた混合物FMを、50s−1の剪断速度でさらに5分間攪拌した。次に、この混合物に、下記表3に示すFA1ストック溶液の量を室温で攪拌しながら添加した。得られた混合物FM1を50s−1の剪断速度でさらに5分間攪拌した。次いで、この混合物に下記表3に示すFA2ストック溶液の量を室温で攪拌しながら添加し、凝集した充填剤粒子を懸濁液中で形成させた。添加が完了した後、得られた混合物を50s−1の剪断速度でさらに5分間攪拌した。次に、スラリーを40000s−1の剪断速度(MTO 5000Q作業チャンバを備えたMegatron MT5000、Kinematica AG,Luzern CH、循環モード、14000rpm)でフロックの脱凝集のためにメガトロン処理に15分間供した。
60g(乾燥)パルプを10dm3の水道水で希釈し、最終紙重量に基づいて全体的な充填剤含有量を得るような量で試験すべき充填剤を添加した。懸濁液を30分間攪拌した。続いて、リテンションエイドとして0.06%(乾燥重量基準)のポリアクリルアミド(Polymin 1530、BASF,Germanyから市販されている。)を添加し、Rapid−Kothenハンドシート作製機を用いて80g/m2のシートを形成した。Rapid−Kothen乾燥機を用いて各シートを乾燥させた。ハンドシートの組成を下記表4に示す。
