Description
−医療分野では、TPUにより作成される部品(例えば、カテーテル)にBaSO4フィラーを使用することで、それを使用しない場合には見ることができないものを、X線により見ることができるようにする。
−BaSO4の比重が高いことを前提として、BaSO4をTPUに添加して、TPUの重量を商業目的のために増加させる。
−BaSO4は、研削砥石の機械産業において使われている。なぜなら、BaSO4が、BaSO4+3Fe→Fe3O4+BaSの反応により、研磨される加工対象物の表面上で、潤滑作用を有するFe3O4の形成を、低温で促進させるからである。
−ロッド3の移動がシリンダー5のベースに対して垂直であり、潤滑無しで、分当たりサイクルが2倍の、正しい使用の場合、耐用寿命は、標準の分当たりサイクルでの耐用寿命と比較して、15%向上した。
−ロッド3の移動がシリンダー5のベースに対して非垂直であり(1°の傾きがあり)、潤滑無しで、標準の分当たりサイクルでの、誤った使用の場合、耐用寿命は、正しい使用の場合、即ち、ロッド3の移動がシリンダー5のベースに対して垂直で、標準の分当たりサイクルで、潤滑無しの場合と比較して、30%向上した。
Claims (9)
