拉雷粘度计测量单位以及粘度换算

拉雷粘度计也称落杆粘度计,是用于油墨粘度测量的。它通过几次测量落杆下落10cm的时间,然后使用随机附带的软件或者用户自己的计算方法即可计算出油墨的粘度和屈服值。拉雷粘度计测试方法符合ASTM标准。面

动力粘度单位换算

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)

动力粘度与运动粘度的换算

η=ν. ρ

式中η--- 试样动力粘度(mPa.s)

ν--- 试样运动粘度(mm2/s)

ρ--- 与测量运动粘度相同温度下试样的密度(g/cm3)
