  • density measurement for Polymers by magneto archimedes levitation simulation and experiments
    Polymer Testing, 2017
    Co-Authors: Peng Zhao, Chengqian Zhang, Jianzhong Fu
    Abstract:

    Abstract In a magneto-Archimedes levitation device, a polymer can be levitated in a paramagnetic medium, and its equilibrium levitated height is mainly related to its density. Here, a novel density measurement method for Polymers via magneto-Archimedes levitation is proposed, in which the relationship between the density and the levitated height is determined through numerical simulation. COMSOL software is employed to simulate the distribution of magnetic field in the device, and FLUENT-EDEM multiphase software is adopted to predict the polymer‘s levitated height. A 3rd-order polynomial equation is fitted by simulation results for density calculation. Several experiments with different devices, different magnets, different mediums, and various Polymers were carried out to verify the proposed method. Experimental results showed that the proposed method has high accuracy (0.0060–0.0130 g/cm3) in density measurements for small polymer samples (∼25 mm3). In general, the proposed method has prospects of broad application in polymer density-based testing.

  • measuring densities of Polymers by magneto archimedes levitation
    Polymer Testing, 2016
    Co-Authors: Peng Zhao, Chengqian Zhang, Jianzhong Fu
    Abstract:

    Abstract In magneto-Archimedes levitation, a polymer can be levitated to a balanced position, and its levitation height is mainly related to the density of the polymer. Here, a novel method for measuring the density of Polymers based on magneto- Archimedes levitation is proposed. For a designed measurement device, an equation can be fitted by a series of experiments with standard density glass beads. Then, the polymer‘s density can be calculated via the equation. In this paper, a device with magnets at a distance of 60 mm was chosen as an example. Experimental results showed that the proposed method could measure all types of polymer with an accuracy of 0.002–0.01 g/cm3. Moreover, the proposed method can clearly distinguish between Polymers with small density differences (
