Computer Controlled Rheometer for High Precision Material Viscosity Analysis

Product Description

Product Description
Capillary Rheometer MLW-400A
Application:
1,This machine is suitable for measuring the shear rate of plastics and polymer materials and the fluidity of the melt under shear stress at a certain temperature, including the apparent viscosity of thermoplastics and thermosetting materials.
2, This rheometer is a computer-controlled intelligent capillary rheometer, which can work under constant pressure, constant speed, constant temperature, different heating rates, different temperatures, different shear rates, etc. The software automatically determines the pressure, temperature, speed and other test parameters of different plastics under different die diameters. The software automatically draws curves and saves and prints data.
3,Different specifications (low temperature type, high temperature type, different pressures, different rod diameters, etc.) can be customized according to user requirements. This machine has a low pressure, single pressure head, and single rod structure. Functional features 1,High data collection frequency , can more accurately record the transition points of materials in different states without missing the key material state transition points; accurately calculate the apparent viscosity at different shear rates.
2,Can achieve the superposition of multiple data curve and display coordinates in various curve forms.
3,The load loading device of the instrument is designed reasonably, using high-precision pressure sensors for data acquisition, eliminating the traditional load sensor acquisition; Dual closed loop of software and hardware, achieving stepless adjustment of speed and loading force; Manual and automatic loading control can be used, which is convenient, fast, and accurate. Inductive manual displacement adjustment;
4,Regarding the coordinate axes of shear viscosity and shear rate curves: During the test, the coordinate axis is the normal coordinate axis. When the test is over, if you want to view the log coordinate axis image, you can directly adjust it with the mouse. So that you can observe the image in two ways, and the lowest point of the coordinate axis is set with the mouse after the test.
5,The whole machine adopts single rod,swing head table structure,which has more beautiful appearance, stronger stability, convenient cleaning, and easier transportation and installation.
6,Scalability: This instrument can be expanded into a wire drawing instrument without replacing the host. Detailed Photos System composition The system structure design adopts a single-bar swing head table design to ensure structural strength and easy cleaning. The transmission structure adopts a Taiwan brand precision ball screw to achieve kinetic energy transmission, and the speed control system adopts an AC servo system to achieve precise control of displacement and pressure. The heating unit adopts a spiral heating wire for overall heating, and the overall temperature of the barrel is uniform. The high-tech measurement and control system and software interface are simple and intuitive, and can set the test mode and related operating parameters, and display relevant curves and calculation results in real time
Test items:
1,Constant speed shear test: it can measure the curve of shear stress and shear rate, and the curve of shear viscosity and shear rate
2,Constant pressure shear test: it can measure the shear viscosity and shear rate curve
3,Step shear rate test: different shear rates can be set according to the user's requirements, the shear stress and shear rate curve, and the shear viscosity and shear rate curve can be measured, and the melt fracture and the minimum flow pressure and shear rate of the melt can be determined according to the changes of the curve during the test.
a.Flow/non-flow test: measuring the relationship between viscosity and temperature, can accurately determine the minimum flow temperature.
b.Melt fracture and flow instability, study the phenomenon of flow instability, including melt rupture and melt fracture. Product Parameters
