Scope Of Application

1, this machine is suitable for the determination of plastics and polymer materials, composite/filler materials, elastomers, etc., shear rate and at a certain temperature, the determination of melt fluidity under the action of shear stress, including thermoplastic plastics and thermosetting materials apparent viscosity.
2, this rheometer is a computer-controlled intelligent capillary rheometer, can be under constant pressure, constant speed, constant temperature, different heating rate, different temperatures, different shear rates, etc., through the software automatically determine the different plastics in different mouth mold environment pressure, temperature, speed and other detection parameters. The software automatically draws curves and saves and prints the data.
3, can be customized according to user requirements of different specifications (low-temperature type, high-temperature type, different pressure, different rod diameter, etc.) models. This model is high-pressure, double-pressure head double barrel, frame door structure.

Technical Parameters

Meet Standards

RT-722B Capillary Rheometer is suitable for meeting the “capillary” part of ISO 11443 “Determination of Plastic Flowability by Capillary and Slit Rheometer” and HG/T 4300-2012 “Determination of Rubber Rheological Properties Plunger Type Capillary Rheometer Method” standard. As well as HG/T 4300-2012 “Determination of Rheological Properties of Rubber Plunger Type Capillary Rheometer Method” standard, to determine the shear rate of plastics and polymer materials, and at a certain temperature, to determine the fluidity of the melt under the action of shear stress, including the apparent viscosity of thermoplastics.

Product Features

1, High data acquisition frequency (more than 2, can realize a variety of data curve superposition; a variety of curves in the form of coordinates display.
2, It can realize superposition of many kinds of data curves; coordinate display of many kinds of curve forms.
3, The instrument’s load loading device is reasonably designed, the use of high-precision pressure sensors for data acquisition, the abolition of the traditional load sensor acquisition; software, hardware, double closed-loop, to achieve the speed, the loading force of the stepless adjustment; can be used manually, automatically two kinds of loading control, convenient, fast and accurate.
4, On the shear viscosity and shear rate curve axis: test test axis for the normal axis, when the end of the laboratory if you want to watch the log axis image can be adjusted directly through the mouse to adjust the log axis, so that you can observe the image of the two ways, while the low point of the axis are set up in the end of the test with the mouse settings.
5, The whole machine adopts “H” type frame structure, more beautiful appearance, stronger stability, and easier to transport and installation.
6, The machine adopts double barrels mainly have some functions are in the single barrel on the basis of the expansion. Measure viscosity is relatively more accurate than a single barrel, because a single barrel is generally measured by the apparent viscosity, apparent viscosity with a single barrel is not the true viscosity of the material, but the double barrel can be a number of parameters for some corrections, measured apparent viscosity relative to a single barrel measured more accurately.
7, The machine software calculations using an open model design, the model can be corrected, different material systems, he measured the results are not the same, two barrels of the two mouth mold can be corrected, (equipped with a long mouth mold and zero mouth mold), while measuring the shear viscosity and tensile viscosity; real-time Bagley correction.Of course, single cylinder can also be, just not double cylinder more accurate.
8, The machine adopts double pressure head double cylinder structure can also do two kinds of specimens or the same kind of specimen at the same time to do twice, is conducive to the same kind of specimen for repeatability comparison and different kinds of specimen data comparison; save time; high work efficiency.
9, Cylinder graphic curve real-time display of pressure, temperature, force, shear rate, the deformation and speed of the two indenter, and the amount of sample remaining in each cylinder.
