拉雷粘度計測量單位以及粘度換算

拉雷粘度計也稱落桿粘度計,是用于油墨粘度測量的。它通過幾次測量落桿下落10cm的時間,然后使用隨機附帶的軟件或者用戶自己的計算方法即可計算出油墨的粘度和屈服值。拉雷粘度計測試方法符合ASTM標準。面

動力粘度單位換算

1厘泊(1cP)=1毫帕斯卡.秒 (1mPa.s)

100厘泊(100cP)=1泊 (1P)

1000毫帕斯卡.秒 (1000mPa.s)=1帕斯卡.秒 (1Pa.s)

1000微 帕斯卡.秒(1000μ Pa.s)=1毫帕斯卡.秒 (1mPa.s)

動力粘度與運動粘度的換算

η=ν. ρ

式中η--- 試樣動力粘度(mPa.s)

ν--- 試樣運動粘度(mm2/s)

ρ--- 與測量運動粘度相同溫度下試樣的密度(g/cm3)
