RheoPower and DataPower Software Packages

Some benefits and fetures by new standpoint.

New Standpoint

Finally something fundamental new in rheology after 140 years use of the Maxwell model by different modifications: Control Theory is the kernel of this Polymer Technology Web, the background was published very recently at high valuated and prestigious scientific journals.

We applied control theory to model the linear relationship between the relaxation modulus, dynamic and shear viscosity, transient flow effects and CAD/CAE/CFD simulations all related to the molecular weight distribution (MWD), sometimes called Molar Mass Distribution (MMD).

Moreover Power law, Cox-Merz rule, time–temperature superposition (TTS) and orientation level are explained by direct simple relation to molecular dynamics using structural models comprising dumb-bells in a statistical tube.

New version of the classical Boltzmann superposition principle explains a novel way and sums all shear histories based on the chain orientation state.

Software Packages

  • You can use these same features, as we have coded software packages for your work as follows:

  • RheoPower rheology software family:

    • RheoAnalyzer detects MWD (Molecular Weight Distribution) and models simultaneously many other viscoelastic flow curves from viscoelastic measurements.
    • RheoDeveloper is for modelling and simulating MWD by giving many other different type viscoelastic flow curves.

  • DataPower software family for CAD/CAE/CFD simulation business:

    • RheoFlow is for simulating simple flows.
    • DataPower Server gives continuous viscoelastic data via TCP/IP protocol to the simulating CAD/CAM/CAE software Clients.

Some Benefits of RheoPower

  • New benefits to your work by the program:
    • The fastest way to analyse viscoelastic material.
    • Accelerates your material development and design of polymerization, extrusion and injection moulding processes.
    • Repeatable results for a sample are computed in a minute.
    • MWD analyses and accurate wide viscoelastic fits are generated as different type viscosities, G' and G'' moduli, relaxation modulus and transient effects difficult or even impossible to measure.
    • Impressive charts of results.
  • These advantages give you many benefits at low cost not even possible to get before.

Some Features of RheoPower

  • The RheoPower software family developed for material analyses and recearch.
    • Molecular Weight Distribution (MWD) is computed directly from viscoelastic measurements.
    • Imported viscosity data can be as a function of frequency, shear rate and other variables.
    • Wide accurate fits also for other viscoelastic properties as transition, relaxation modulus and spectrum.
    • Computation principles are proofed by Control Theory.
    • The best proof of the published principle is the computation results.
    • Package is for design polymerization, extrusion, injection and other processes.
    • As a general principle software can be used with any heterogeneous materials as cellulose pulp, blood or even soil.
    • Used main polymer structure function P relates directly to the chain orientation level.
    • Analytical and more practical characteristic models give flexibility.
    • Microsoft SQL Server database allows RheoPower seamlessly fit into any laboratory environment and store rheological and MWD also from GPC/SEC measurements.
  • These features motivate cost-savings, control, and efficiency of your work.
On the other pages you find demonstration and training flash videos and instructions for software packages.

Demos, Trials and Quotations

Free tiny version for evaluation purposes can downloaded directly as anonymous without any authentication.

We suggest strongly to quote and agree some free test analyses for demonstrating the capabilities of software for your data measured according to instructions.

You can also request a free trial edition of fully functional for 30 days RheoPower software package.

Summarized

The new principle based on Control Theory gives much higher accuracy between deformations and properties as newer earlier. Thus this ultra-correlation looks unbelievable, so that please study other pages and theory papers to evaluate yourself the case and reasons for our success.
