表面粗さの測定
PRIMOSシステムは照明ユニットと撮影ユニットからなる。照明ユニットは、デジタル微小鏡投映機を用いて、表面上に直線を投映する。投映される平行な直線は、表面構造により偏移され、すなわち、変調される。
測定野の寸法: 14.5x23.4mm2
断面長さ: 20.0mm
表面粗さ: 縁から1.0mm離れる(Xm=21.4mm;Ym=12.5mm)
フィルタ: 3次多項式フィルタ
剥離強度(接着力)の試験はPSTC−1に準拠して行う。
接着テープを所定の固い接着基板(ここでは鋼板)に貼り、一定の剪断負荷をかける。耐久時間を分単位で測定する。
接着テープの1cm幅の試験片を、研磨した鋼板(試験基板)に、5cm長さにわたり、2kgのロールを10回転動して貼付する。両面接着テープは、背面を50μm厚のアルミニウム箔で被覆する。試験片を190μm厚さのPETフィルムで強化し、続いて固定装置を用いて縁を真っ直ぐに切断する。その際、強化された試験片の縁は、鋼板の縁から1mm突出させる。板は15分間試験条件下(23℃、相対湿度50%)、ただし無負荷で、測定装置中で平衡処理される。続いて、所望の試験用錘(ここでは50g)を吊るし、剪断負荷が接着面に平行に生じるようにする。解像度がμm領域の移動量測定器が、剪断移動量を時間の関数としてグラフに記録する。
低温耐衝撃性試験により、両面接着性(d/s)感圧接着テープの突発的な動的衝撃負荷への感受性を調べる。試験しようとする接着テープを用いて、試験体を、PC板とABS枠から製作する。試験しようとする両面接着テープは、これら継目構成部品の間に貼られ、続いて6kgの錘を5秒間載せる。
塗工された自己接着剤の嵩密度あるいは密度は、目付け量とそのときの層厚の比から決定される。
