Abstract
【解決手段】本発明は、ホスフェート層で被覆された方向性磁気ストリップ、すなわち添加剤としてコロイド成分および少なくとも1つのコロイド安定剤(A)を含有するホスフェート溶液が磁気ストリップに塗布された方向性磁気ストリップの製造方法に関する。
【選択図】図1
Description
0.5<Al(H2PO4)3:SiO2<20、好ましくは、
0.7<Al(H2PO4)3:SiO2<5、より詳しくは、
Al(H2PO4)3:SiO2=1.36
・ホスフェート溶液とストリップ表面との相互反応
・コロイド−安定化効果
・ホスフェート溶液の使用特性
ホスフェート溶液またはホスフェート/コロイド混合物をビーカに入れる。次に、評価すべき添加剤を、撹拌しながら添加する。金属的に裸の表面をもつ計量(重量測定)した磁気ストリップサンプルが溶液中に浸漬し、数回浸漬した後に計量する。この測定値から、重量の減少(酸洗い損)が計算される。この方法は、種々の温度で部分的に行われる。
ホスフェート溶液またはホスフェート/コロイド混合物をビーカに入れる。次に、評価すべき添加剤を、撹拌しながら添加する。金属的に裸の表面をもつ計量した磁気ストリップサンプルが溶液中に浸漬する。数回露出した後、溶液の曇りが評価されかつゲル化に関して制御される。試験は種々の温度で行われる。
例えば図1に示すように、ゾル/ゲル変換は、粘度計で測定して非常に良い状態にある。
評価すべき同体積の溶液を、ミリメートルペーパ(millimetre paper、Millimeterpapier(英、独訳))が下に敷かれたガラスディスク上に置く。10分間の実行時間の後、液体が拡散した面積を測定する。この目的のため、面積を円形面積として近似し、円形の直径を面積等価量として与える。
