Application Introduction / Vibration Absorption and Viscoelastic Properties of Polyolefin-based Materials - Measurement and Control of Residual Solvent Levels in the Wire Coating Process

◆Vibration Absorption and Viscoelastic Properties of Polyolefin-based Materials Materials with vibration absorption properties are attracting attention as they enable improvements in labor and living environments through soundproofing and vibration isolation. It is believed that vibration absorption occurs due to energy loss associated with internal friction in the material, and the amount of energy loss is known to correlate with the material's viscoelastic properties. By conducting viscoelastic measurements of the material, information regarding vibration absorption can be obtained. ◆Measurement and Control of Residual Solvent Levels in Wire Coating Processes Insulated wires used in discrete wiring circuit boards can cause various product defects (blisters, delamination, etc.) due to residual solvents present in the wire coating material. However, by utilizing thermal analysis techniques for the detection and quantification of residual solvents, it is possible to implement high-precision quality control.

Recently, fine bubbles, which are tiny bubbles smaller than 100 μm and are referred to as "fine bubbles," have attracted attention in various fields such as the environment, agriculture, food, fisheries, and medicine, due to their ability to impart various functions to liquids. Fine bubbles are classified into two types based on their size: microbubbles and ultrafine bubbles. Recently, there has been a growing interest in ultrafine bubbles, which have a lifespan of several weeks to months. However, listening to the voices of researchers and users reveals some skepticism, which has become one of the issues hindering the spread of fine bubble technology. On the other hand, we have challenged the elucidation of the stabilization mechanism of ultrafine bubbles from a new perspective by enabling the control of number density exceeding 10 billion particles/mL without pressure or concentration operations using our ultrafine bubble generation technology. In this seminar, we will provide a fundamental explanation of fine bubble technology, including the basic physical properties, characteristics and functions, device technology, measurement and evaluation methods, and case studies, to promote research and utilization of fine bubbles based on a correct understanding.

Sekiguchi Iron Works Co., Ltd. will exhibit at the "Minami-Shinshu Environmental Messe 2025" held at S-Bird in Iida City, Nagano Prefecture. This exhibition will be held simultaneously with the "Environmental Industry Trade Fair" taking place the day before. It will be held over the weekend, with many family-friendly events planned. We encourage those who usually find it difficult to visit to take this opportunity to come. Our product exhibition area is located about 10 minutes from the venue. We sincerely look forward to your visit.
