(2−1)高温離油特性
JIS K 2220:2013に規定される「11離油度試験方法」に従い、試験温度120℃、試験時間24時間の条件下で離油度を算出した。
JIS K 2220:2013に規定される「18低温トルク試験方法」に従い、試験温度−40℃の条件下で起動トルクを測定した。
レオメーター(Anton Paar社製)で、測定温度100℃の条件下で剪断粘度を測定した。なお、剪断粘度とは、角度2°のコーンとプレートとの間に試料油を挟み、剪断速度を0s−1から600s−1まで徐々に上げていき、剪断速度が600s−1の時の粘度である。
往復動試験機を用い、下部試験片上に試料油を塗布し、上から上部試験片を押しつけ往復動させた。往復動させた時の上部試験片と下部試験片との間に発生する摩擦力から静摩擦係数を測定した。試験条件を以下に示す。
上部試験片:直径10mmのポリオキシメチレン(POM)ボール
下部試験片:炭素鋼(S45C)プレート
試験荷重:3kgf
試料油の塗布量:0.05g
摺動速度:1mm/sec
試験温度:80℃
摺動距離:10mm
評価結果を、表1および表2に示す。
