Developed two types of geometries for the small, high-performance ONRH-type rheometer.

A high-functionality and high-performance rheometer that does not use air bearings. It is suitable for rheological measurements of low-viscosity liquids. No need for clean air management!

This is a rheometer suitable for rheological measurements of low-viscosity liquids, adopting a double-cylinder method with an outer cylinder rotation (capable of measuring viscosity and elasticity). The torque measurement section features a practical elastic hinge-type bearing developed by AIST, achieving high-sensitivity torque measurement without using air bearings. This eliminates the need for clean air management, allowing for more flexible installation locations. It also contributes to CO2 reduction. Additionally, it is easy to maintain and offers advantages in terms of size and cost. New measurement method: Dynamic viscoelastic measurements can be performed under steady flow conditions. We encourage you to give it a try. 【Features】 ○ Outer cylinder rotation, inner cylinder detection method with separate drive and detection axes (strain-controlled type) ○ Upper support method for inner and outer cylinders facilitates sampling ○ The standard glass outer cylinder allows for observation of the sample's condition during measurement ○ The sample volume is relatively small, with a standard of about 4ml (minimum approximately 2.5ml) ○ Various measurements, including dynamic measurements, can be easily performed *Please feel free to contact us for more details.

Visualization of viscoelastic measurement: It can be seen that the viscosity and dynamic viscoelastic co-measurement values change in response to the state of the samples before and after applying high shear rates.

Measurement example by sample observation [Foam Hand Soap] The images show the final state immediately after sampling and after high shear measurement. • The state of the foam becomes finer under high shear. • When the shear is not large, coalescence and rising of the foam occur. • It can be seen that the viscosity and dynamic viscoelastic co-measurement values change in correspondence with the state of the sample before and after applying high shear rate. • The viscosity increases in response to the foam becoming finer. • The elasticity increases as the foam becomes finer. *For more details, please refer to the PDF document or feel free to contact us.

Supports rheological measurements of various samples! Introducing examples of viscoelastic measurements with the ONRH type rheometer.

We would like to introduce a case study of viscoelasticity measurement using the 'ONRH-type rheometer' handled by Daicai Giken. In a measurement example through sample observation, when measuring foam hand soap, changes were observed where the viscosity increased in response to the foam becoming finer. The materials explain the shear rate dependence of viscosity, as well as frequency dependence and viscoelastic strain amplitude dependence, using graphs. 【Features】 ■ Supports rheological measurements of various samples ■ Temperature control with a dedicated constant temperature bath ■ Collaboration of rheological measurements with other measuring devices *For more details, please refer to the PDF materials or feel free to contact us.

This is a graph of the gelation of dilute gelatin aqueous solution measured by a rheometer.

This is a graph of the gelation of a dilute gelatin aqueous solution measured by a rheometer. • In the first few hours, only G” increases, and later G’ rises, surpassing G” and resulting in gelation after about one day. By the way, at a stiffness of 1 Pa, it cannot maintain its shape when taken out and will flow (edible jelly has a stiffness of several hundred 100 Pa). *For more details, please refer to the PDF document or feel free to contact us.

CLT, which has been widely adopted in the construction field, is now expanding its applications into the civil engineering sector. The "Hyper CLT Mats" are civil engineering CLT products that utilize wood CLT as temporary materials. Traditionally, steel plates have been the mainstream choice for temporary roads, access routes, and heavy machinery yards. The Hyper CLT Mats introduce a new option of "wood" to that market. The 5x10 mats weigh approximately 230 kg, making them lightweight and easy to install and remove with small machinery, with a maximum capacity of 40 mats on a 10-ton truck. They also have advantages in terms of workability and transportation efficiency. Moreover, they offer added value that can only be achieved with wood, such as glare reduction, noise control, CO2 fixation, and consideration for aesthetics. This product is expected to be a new proposal for not only construction companies but also building material firms, lumber companies, and material trading companies. It is a registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS, with the registration number "TH-250021-A." The use of wood is not limited to construction anymore. The utilization of Hyper CLT Mats is expanding as a new market that connects civil engineering and wood.

In civil engineering sites such as mountainous areas and construction sites, it may be necessary to use wooden boards on slopes or inclined access roads. Hyper CLT boards are civil engineering materials utilizing wood CLT, which can be laid not only on flat ground but also on sloped terrain. They can be used for temporary roads, access routes, heavy machinery entry paths, and measures against muddy conditions, creating a driving environment that takes advantage of the unique surface characteristics of wood. The 5×10 board weighs approximately 230 kg, and the 5×20 board weighs about 460 kg, making them lightweight and easy to install and remove even with small machinery, which is a notable feature for maneuverability in narrow sites. This wooden board is registered as a technology under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS system as "TH-250021-A," and can also be utilized for safety measures and innovative ideas in public works.

Metal cracks are one of the concerns in equipment maintenance operations. Repairs using conventional welding methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" or "secondary damage." Hinode Waterworks Equipment 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 with heat. Repairs can be performed even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.
