• Optical microscope

Non-contact measurement of thermal diffusivity using a laser. Measurement of resin-based materials is also possible.

The ThermoWave Analyzer TA measures thermal diffusivity using a non-contact method with a laser. Since the thermal conductivity of composite materials made of fillers and resins varies significantly with the mixing ratio, measuring thermal diffusivity is essential. Measurement of resin-based materials is also possible. Please contact us for more details.

Thermal conductivity distribution measurement and the anisotropy of thermal diffusivity in each part can be evaluated.

Here is an example of evaluating thin polyimide sheets. Polyimide sheets are resin materials primarily used as insulating substrates and insulating layers in electronic circuits. This time, we measured the thermal diffusivity in the thickness direction using a ThermoWave Analyzer TA on a sheet with a thickness of 7.5 μm. Even with the same polyimide sheet, there are significant thermal differences depending on the thickness. When comparing examples of 25 μm and 7.5 μm using the measure of thermal diffusion time, there is nearly a tenfold difference. The thinner sheet diffuses heat in one-tenth the time. For in-plane measurements, it is relatively easy to achieve time resolution since the distance between the heating point and the detection point can be established. However, for thickness direction measurements, it is necessary to detect rapid temperature changes, which affects the basic performance of the equipment. Traditional measurement methods make the measurement itself difficult. Additionally, at a thickness of 7.5 μm, the thermal effects of surface blackening treatment cannot be ignored, so we have devised methods to minimize these effects during sample preparation and measurement. The measurement results are as follows: Thermal diffusivity in the thickness direction: 0.103 × 10^-6 m²s^-1. This value is approximately 30% lower compared to the 25 μm thick polyimide.

In recent years, the miniaturization and high output of electronic devices have rapidly advanced, and as a result, thermal management (heat dissipation) has become a very important issue. Traditionally, heat dissipation has been maintained by using metals, but in recent years, it has begun to be replaced by "high thermal conductivity resins." High thermal conductivity resins are "lightweight" and have "moldability" compared to traditional metals, are "corrosion-resistant," and above all, have the advantage of being "low-cost." However, there is also the disadvantage of low thermal conductivity, and many material manufacturers are actively developing solutions to address this issue. It is expected that "high thermal conductivity resins" will become mainstream in the future. On the thermal properties blog, we introduce examples of thermal conductivity measurements of "high thermal conductivity resins." http://blog.thermal-measurement.info/archives/cat_50051425.html

Understanding the mechanism of heat transfer and effectively dissipating heat is important! Here we introduce various methods for measuring thermal properties.

Due to factors such as "miniaturization = fanless design" and "widespread use of power devices = increased heat generation," thermal issues have become important. Thermal conductivity measurement can be broadly classified into two categories: "steady-state method" and "transient method." The steady-state method provides direct thermal conductivity values and requires relatively large samples. The transient method can measure thermal diffusivity and thermal effusivity, and it is possible to measure with relatively small samples. We provide further detailed explanations, so please take a look at the PDF download below. 【Characteristics of the "Steady-State Method" and "Transient Method"】 ■ Steady-State Method - Direct thermal conductivity can be obtained - Requires relatively large samples ■ Transient Method - Can measure thermal diffusivity and thermal effusivity - Can measure with relatively small samples - Requires specific heat capacity and density *For more details, please refer to the PDF document or feel free to contact us.

In future public works, not only construction quality but also safety measures, environmental considerations, labor-saving, and the use of new technologies will be important, along with the ingenuity applied on-site. In this context, the "Hyper CLT Board," a wooden lightweight mat using CLT, can be utilized. It can be used as a wooden mat for temporary roads, access routes, and heavy machinery work yards, and the 5×10 board weighs approximately 230 kg, making it relatively lightweight. In addition to ease of installation, removal, and relocation, it features the suppression of glare and metallic sounds unique to wood, as well as environmental considerations. Furthermore, it is a product that can easily incorporate proposals for the use of new technologies and creative ideas, as it is registered with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS as "TH-250021-A." However, simply being registered with NETIS does not automatically result in additional points. What is important is to clarify the purpose and effects of its use on-site. Wooden mats, NETIS, civil engineering, CLT. The Hyper CLT Board is a new option to connect on-site ingenuity to evaluation.

Our company has launched the new "Kappa twin" dual-wheel caster for ultra-heavy load transport. It achieves a high load capacity of up to 2,200 kg per wheel, making it an optimal solution for transporting heavy items in industries such as automotive, aerospace, special vehicles, and heavy industry. The dual-wheel structure distributes the load, balancing high load capacity with excellent mobility. By reducing starting and rolling resistance, it supports smooth transport even for trolleys in the several-ton class. Additionally, it excels in turning performance, contributing to improved maneuverability in limited spaces. It is also suitable for AGVs (automated guided vehicles) and heavy transport trolleys, providing the stability, durability, and safety required in high-load environments. It covers weight ranges that were difficult to address with conventional products, contributing to solving transport challenges in manufacturing settings. This new product is recommended for companies looking to transport ultra-heavy items "more lightly and more safely."

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs often change the base material around the crack due to heat, leading to residual stress and deformation, which constantly carries the risk of "crack recurrence" and "secondary damage." Hinode Waterworks Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.

Japan is among the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of significant earthquakes occurring. For the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake measures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" ◎ For more details, please download the materials or contact us.
