The FT4 Powder Rheometer®- 一种用于测量粉末流量和粉末行为的通用粉末测试仪。
The FT4 was designed with one purpose in mind – to characterize the rheology, or flow properties, of powders. This remains a primary function today, but the instrument, accessories and methodologies have been continuously developed to the point where the FT4 is now considered a universal powder flow tester.
一种工具中的四种测试方法：
- 独特的动态流
- 全自动剪切电池（根据ASTM标准D7891）
- 散装特性

Technology
The FT4 employs unique technology for measuring the resistance of the powder to flow, whilst the powder is in motion. A precision ‘blade’ is rotated and moved downwards through the powder to establish a precise flow pattern. This causes many thousands of particles to interact, or flow relative to one another, and the resistance experienced by the blade represents the difficulty of this relative particle movement, or the bulk flow properties.
通过以精确和可靠的方式移动刀片可以实现出色的可重复性。FT4的高级控制系统准确地设置了刀片的旋转速度和垂直速度，从而定义了螺旋角和尖端速度。
为什么粉末是综合体？
Powders are complex materials. Often perceived as just a collection of particles, they are in fact a complex mixture of solids, liquids and gases. They comprise of solids in the form of particles; gas, usually in the form of air between the particles; and water, either on the surface of the particle or within its structure. The behavioral characteristics of these unique materials are difficult to model and predict from first principles.
Powders exhibit many behavioral characteristics, which determine how they perform during processing and in final application. These characteristics are often independent of one another, so it is important to understand and to be able to measure the influence of each, if a powder is going to be fully characterized.
所有处理环境的性质是不可避免的，并且正在处理的粉末将在不同的压力方面处理。为了充分预测粉末的过程中的性能，必须衡量和量化其对这些外部变量的响应。
动态方法
The FT4 is a truly universal powder tester, with four categories of methodologies, defined as Bulk, Dynamic Flow, Shear and Process.

Shear Cell and Wall Friction
Shear Cell and Wall Friction
Shear Cell and Wall Friction Kits can be attached to the FT4 to determine shear properties of a powder, including Unconfined Yield Strength and Flow Function, and the Wall Friction Angle associated with a given material of constructions (in accordance with ASTM D7891). Shear and wall friction properties can be used to determine critical hopper geometries using the Hopper Design function of the FT4 Data Analysis software.
