Abstract
Description
実施例1:粉末の焼結
約50gのPEEK粉末(VESTAKEEP 2000 FP)を、125μmの目開きを有するふるいを用いて手動でふるい分けした。次に、<125μmの画分に、9:1(w/w)の比で、酸化鉄(II/III)(50~100nm)、<5μmの酸化鉄(II/III)、または超常磁性コアシェル型粒子(コア:約13nm、シェル:二酸化ケイ素;Evonik社製MagSilica;d50粒子径約200nm)を加えた。各粉末混合物10gを製造した。次に、この粉末混合物を、J. Engelsmann AG社製PRM Mini II型ドラムフープミキサーで、直径5mmの12個の粉砕球を用いて40rpmで約2時間にわたって微粉砕混合した。次に、この混合粉末を個別にシリコーン型に充填し、誘導コイル(平面形状;直径5cm;巻数N=4~5)下にて粉末床表面から<3mmの間隔をあけて周波数1MHzで10秒間焼結させた。
印刷可能な水性MagSilicaインクの製造のために、まず、MagSilica含有量が比較的高い分散液を製造した。
MagSilica分散液の製造には、MagSilica HS(Evonik社製)を用いた。分散液を製造するために、連結水冷式のダブルジャケット付き分散槽に脱塩水100gを装入し、次いでこれにMagSilica粉末45.8gを段階的に加えた。その際に、容器中央に設置したディゾルバーディスクを用いて、約900~2000min-1の範囲で分散を行った。温度を、約18℃で一定に保った。MagSilicaを全量加えて均一に分散させた後、ディゾルバーディスクを取り外し、超音波ソノトロードに交換した。ソノトロードの出力は、約400Wであった。その後、ダブルジャケットの冷却により温度を同様に約18℃に一定に保ちながら、超音波による分散を30分間行った。分散終了後、ソノトロードを取り外して分散液の特性を評価した。分散液の強熱残分は33.5%であり、分散液の粘度は、温度23℃で、せん断速度100s-1では72.7mPasであり、せん断速度10s-1では493.1mPasであった(Physica MCR 300、Anton Paar社製)。
水性MagSilica含有インクを製造するため、上記のストック分散液2.5gをTegoWet 500(湿潤添加剤)10mgおよび水7.49gと混合し、KOH希釈溶液でpH値を10.5に調整し、次に、この混合物を超音波フィンガー(0.5;70%、5分)で処理した。その後、この分散液のpH値をモニタリングし、必要に応じて再調整した。インクを印刷する前に、パルプで濾過した。
DIN規格5Aの引張試験片を製造するために、まず、PVC製のコーティング基材上に、150μmのVestosint 1115と上述のインクの印刷層とを交互に12層、適切な形状(DIN 5A断面)に製造した。12層すべてをまとめて、出力5kW、周波数980kHzで焼結させた。
液滴速度:7.1m/s
粘度(30℃、1000s-1):1.84mPas
表面張力:21.4mN/m
密度:1.09g/ml
