目前测定流体粘度的仪器有两大类,一类是毛细管粘度计,只能测定牛顿流体的运动粘度,在粘度计量传递单位用得较多;另一类是旋转式粘度计,在工业生产与科研中用得较为普遍。目前旋转式粘度计国外发展较快,品种也很多。比较先进的有:具有多种功能的德国HAAKE公司的旋转式粘度计,可作流变、蠕变、振荡、弹性试验,粘度范围在25×10~(-2)～25×10~(12)mPa·s的英国卡瑞·梦得（CARRI—MED）控制应力粘度计等。国内旋转式粘度计的研制与生产起步较晚,发展也比较缓慢,应用较为普遍、生产批量较大的 NDJ79型旋转式粘度计,近10年来没有多大变化,其他类型的旋转式粘度计,品种、批量均有限,特别是能方便地测定非牛顿流体流变特性的流变仪的开发与研制,就显得十分迫切。这主要是绝大
The current measurement of fluid viscosity instruments have two categories, one is the capillary viscometer, Newton can only determine the kinematic viscosity of the fluid in the viscometer transmission unit used more; the other is a rotary viscometer, in the industrial production and Used in scientific research is more common. At present, rotary viscometer developed rapidly abroad, there are many varieties. More advanced are: HAAKE with a variety of functions of the company’s rotary viscometer, for rheological, creep, oscillation, flexibility test, the viscosity range of 25 × 10 ~ (-2) ~ 25 × 10-12 ) mPa · s British CARRY dream (CARRI-MED) control of stress viscometer and so on. Domestic rotary viscometer development and production started late, the development is relatively slow, the application is more common, large volume production NDJ79 rotary viscometer, the past 10 years has not changed much, other types of rotary viscometer, variety , The batch size is limited, especially for the development and research of the rheometer which can conveniently measure the rheological properties of non-Newtonian fluids. This is mainly vast
