拉雷粘度計(jì)測量單位以及粘度換算

拉雷粘度計(jì)也稱落桿粘度計(jì),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(jī)附帶的軟件或者用戶自己的計(jì)算方法即可計(jì)算出油墨的粘度和屈服值。拉雷粘度計(jì)測試方法符合ASTM標(biāo)準(zhǔn)。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(yùn)動粘度的換算

η=ν. ρ

式中η--- 試樣動力粘度(mPa.s)

ν--- 試樣運(yùn)動粘度(mm2/s)

ρ--- 與測量運(yùn)動粘度相同溫度下試樣的密度(g/cm3)
