（Blue Star R&D Inc. continues to deliver powerful ultrasonic cleaners for large 2.5-, 4-, and 5-ton molds. The molds are placed in a large ultrasonic tank with a reinforcing H-shaped steel frame. After installation, the cleaning solution is rapidly introduced, and when the tank is full, ultrasonic cleaning continues as the large ultrasonic transducer travels…続きを読む
Blue Star R&D is the first company in the world to successfully extract cellulose from cedar, sugarcane residue bagasse, and corn meal by irradiating them with powerful ultrasound, and to produce nanocellulose and nanocellulose fibers as well. If cellulose can be extracted from interfering substances such as lignin by ultrasound, cellulose can be easily converted…続きを読む
We will develop ultrasonic cavitation application technology in all directions. Last year, we succeeded in converting hyaluronic acid with a molecular weight of over 2 million, an organic ultrahigh polymer, into low molecular weight hyaluronic acid with a molecular weight of less than 1000, and in generating cellulose, nanocellulose, and nanocellulose fibers from various biomass…続きを読む
Blue Star R&D developed and commercialized an ultrasonic deburring and cleaning device for manifolds. The device is installed in the laboratory at the head office. Manifold deburring and cleaning experiments will be accepted from April 8, 2024. The size of the manifold to be considered is a manifold with a cross section that fits within…続きを読む
To explain the behavior of ultrasonic cavities, I have explained that at 20 KHz, a shock wave is generated outward from the central core of the cavity in about 1/40,000 of a second (positive shock wave), and in the next 1/40,000 of a second a shock wave is generated toward the central core (negative shock…続きを読む
Cleaning after buffing has been a challenge in the cleaning industry for 40 years, and removal methods have changed over time. In the past, solvents were often used, but now alkaline cleaners are often used. When using alkaline water-soluble cleaning agents, the temperature should be set to 35°C to 55°C and ultrasonic irradiation should be…続きを読む
