高周波粘弾性 Product Lineup

If you could send a sample, there would be no need for proficiency in measurement or to maintain expensive equipment. Recently, measurement accuracy has improved, allowing for more precise measurements of inkjet inks and similar materials than before. The measurement of megahertz hysteresis loss in liquids such as inks can also be performed similarly to solids. In the high deformation properties of inks for inkjet printers (IJ), which involve high-speed droplet ejection, the Cox-Merz rule, which treats strain rate (1/s) and deformation frequency (rad/s) as equivalent, (https://www.cerij.or.jp/service/05_polymer/rheology_freq-dependence.html) may allow for evaluation. (No freezing occurs even at megahertz) ☆ This was published in the Journal of Applied Physics.

Until now, viscoelastic measurements were generally limited to around 100 Hz, but higher frequencies were desired for actual products. The HFR002 can measure complex viscoelasticity using ultrasonic propagation. All strains propagate at the speed of sound, resulting in overall deformation. Those with significant attenuation are referred to as viscoelastic materials. The storage modulus can be measured at the speed of sound. The loss modulus can be measured from the attenuation. Our proprietary surface method allows for the analysis of surface degradation and the effects of the skin layer, which were previously impossible to assess.

The "HFRU" is a high-frequency viscoelastic measurement device that can perform viscoelastic measurements using ultrasound while applying low-frequency vibrations and rotations. It is expected to measure megahertz viscoelasticity under large strains, which was not possible before, allowing for the understanding of nonlinear viscoelastic properties of high-functionality fluids under shear. In addition, it can perform simultaneous measurements with rheometer functions, and it is capable of measuring not only bulk properties but also surface megahertz viscoelasticity if the loss is significant. 【Features】 ■ Easily set up on MCR ■ Measurement at eccentric positions is possible ■ Optical observation can be performed simultaneously with ultrasonic measurement (separately) ■ Rheometer attachment type *For more details, please refer to the catalog or feel free to contact us.

The "HFR002" is a high-frequency viscoelastic measurement device capable of measuring viscoelasticity using ultrasound. It is expected to provide insights into high-frequency viscoelastic properties that are closely related to the friction of rubber, such as that found in tires. For materials whose physical properties change due to electric fields and other factors, it is possible to observe the process of change through megahertz viscoelastic measurements under conditions similar to those of the actual device. Not only bulk properties but also surface megahertz viscoelasticity can be measured. 【Features】 ■ Simultaneous optical observation with ultrasonic measurement ■ Specialized for high-frequency range ■ No need for temperature-frequency conversion, thus no need for a low-temperature bath ■ No sample preparation required ■ Results available on-site For more details, please refer to the catalog or feel free to contact us.
