Description
パルプ乾燥固形分濃度が2.0質量%以上を有する製紙工程の最後の貯槽(チェスト)を経た後、白水あるいは清水、工業用水等で希釈され2.0質量%より低い製紙原料にされ、通常の製紙工程では抄紙機の直前にはパルプ乾燥固形分濃度0.5〜1.5質量%に希釈されており、本発明もその範囲内で適用される。
板紙製造原料100mLをポリビーカーに採取し、硫酸バンドを2質量%添加(マシンチェスト添加想定)、200rpmで40秒攪拌、ロジン系サイズ剤を0.65質量%添加(種箱添加想定)、10秒攪拌、有機系凝結剤を200ppm添加(種箱添加想定)、30秒撹拌した(添加は何れも対製紙原料固形分)。その後、ワットマン濾紙No.41により濾過し、濾紙上の原料を清水500mLで希釈し、800rpm、60秒撹拌後、TAPPIスタンダード抄紙機(60メッシュワイヤー使用)で抄紙した。抄紙した湿紙を4.1kgf/cm2で5分間、プレス機にてプレス脱水し、回転式ドラムドライヤーで105℃、3分間乾燥後、25℃、RH65%の条件で18時間調湿し、坪量及びCobb吸水度を測定した。結果を表1に示す。
実施例1と同様原料を対象に同様な有機系凝結剤を用いて試験を実施した。製紙原料100mLをポリビーカーに採取し、有機系凝結剤を対製紙原料固形分200ppm添加(リファイナー添加想定)、200rpmで30秒攪拌、硫酸バンドを2質量%添加(マシンチェスト添加想定)、40秒攪拌、ロジン系サイズ剤を0.65質量%添加(種箱添加想定)、40秒攪拌した(添加は何れも対製紙原料固形分)。その後、ワットマン濾紙No.41により濾過し、濾紙上の原料を清水500mLで希釈し、800rpm、60秒撹拌後、TAPPIスタンダード抄紙機(60メッシュワイヤー使用)で抄紙した。抄紙した湿紙を4.1kgf/cm2で5分間、プレス機にてプレス脱水し、回転式ドラムドライヤーで105℃、3分間乾燥後、25℃、RH65%の条件で18時間調湿し、坪量及びCobb吸水度を測定した。結果を表1に示す。
