Evaluation of pore distribution in non-woven fabric sheets

Important analysis items for performance evaluation and quality control of functional materials! Evaluation of pore size and pore distribution of non-woven sheets and membrane materials.

This is an example of evaluating the maximum pore diameter and pore size distribution of non-woven fabric sheets using the bubble point method. The sample is immersed in a chemical solution, and air pressure is applied. The pressure is increased until it overcomes the surface tension of the chemical solution absorbed in the sheet, at which point the appearance of bubbles occurs; this pressure is referred to as the bubble point. The maximum pore diameter can be calculated based on the bubble point pressure and the surface tension of the chemical solution. 【Calculation Formula】 ■d = Cy/P ・d: maximum pore diameter ・C: constant ・y: surface tension of the chemical solution ・P: differential pressure *For more details, please refer to the PDF document or feel free to contact us.

I confirmed the blocking function of polymer melting at high temperatures!

We conducted material analysis of the separator used in commercially available Li-ion batteries using FT-IR analysis, and confirmed its function of blocking polymer melting at high temperatures. The document presents the material analysis of Li-ion battery separators and observations of changes in the separator's condition under high-temperature environments, using graphs and photographs. [Analysis Overview] ■ Material analysis of Li-ion battery separators ■ Observation of changes in the condition of the separator under high-temperature environments - The condition changes of the separator were observed over time at a constant temperature of 135°C using FIB/SEM. *For more details, please refer to the PDF document or feel free to contact us.

Crittec Industries Co., Ltd. published a newspaper advertisement (black and white, full-page 15 columns) for the bridge expansion device "Hybrid Joint" in the February 26, 2026 issue of the Sankei Shimbun Tohoku 6 Prefectures edition. In Japan, the number of bridges over 50 years old is rapidly increasing, making the longevity of bridges a critical issue. The expansion devices, which are considered a cause of bridge damage, require high water-tightness and long-term durability. Our expansion device "Hybrid Joint" offers multiple types tailored to different bridge types and conditions. Among them, the "Hybrid Joint 3LII type" has demonstrated a durability of 100 years in fatigue loading tests conducted by a third-party organization. It has successfully passed 12 million cycles of repeated loading at a maximum load of 260 kN, confirming performance equivalent to a 100-year design service life for bridges. We have numerous delivery records in the six Tohoku prefectures and can accommodate a wide range of bridge types, including steel and PC bridges. The special website linked to the advertisement allows for the review of detailed materials and inquiries or requests for documents. Please make use of it for comparing and considering bridge renewal and repair plans. Crittec Industries will continue to contribute to the longevity of bridges nationwide, starting with the Tohoku region.

Born from the voices on the ground, high brightness × wide coverage × high cost performance linear lighting. To respond to the production site’s demands for "brighter," "wider," and "easier to use," we have launched the new high brightness linear lighting LLWK-N series, which balances high brightness and high cost performance. While achieving approximately three times the illuminance compared to the conventional LLWG series, we maintain an easy-to-implement price range. With a natural heat dissipation structure suitable for clean rooms and a compatible design that makes it easy to replace existing lines, we are thoroughly pursuing the "ease of use" required on-site. For detailed product specifications and inquiries about implementation, please feel free to contact us.

Our company not only sells building materials but also carries out flooring and wood deck construction within Okinawa Prefecture. For more details, please contact us. - Raised floor - Steel floor - Direct installation - Conventional floor - Recycled wood / wood deck

Adopted by major semiconductor manufacturers. Over 10,000 copies produced annually. This high-quality cleanroom notebook (dust-free paper notebook) has been loved for many years in "Silicon Island Kyushu," where some of the world's leading semiconductor manufacturing companies are located. It uses Sakurai Co., Ltd.'s "Staclean RV (recyclable dust-free paper)" and is designed for professional use, minimizing dust generation to the utmost. It supports "writing" in semiconductor factories, precision equipment manufacturing sites, and medical environments. [Main adopting companies: SCK, JASM, RSMC, and many others] ■ Three reasons why Yoneura Printing's "Cleanroom Notebook" is chosen: - Proven track record: Adopted by multiple major semiconductor companies in Kyushu, with an annual production and sales record of over 10,000 copies. - Use of the highest quality dust-free paper: The main paper uses "Staclean RV Violet 72g," and the cover uses "Clean Paper RC 175g," achieving low dust generation. - Size options tailored to the workplace: A lineup ranging from standard A4 and B5 sizes to convenient mini sizes that fit into cleanroom pockets. ■ Product lineup: - Clean Notebook A4 @400～ - Clean Notebook B5 @380～ - Clean Pocket (mini size) @225～
