NICHIBAN and the Shimane Industry Technology Center in Japan jointly developed a new packaging material, Nichiban UM, which can extend the life of dye-sensitized solar cells. Mikuni, who has been engaged in the basic research of adhesives, produced prototype packaging materials and studied and analyzed the dye-sensitized solar cells at the Shimane Prefecture Industrial Technology Center, contributing to improving its characteristics. The encapsulant material developed this time is a UV-curable acrylic resin that can be hardened by irradiating ultraviolet light and visible light at a wavelength of 200 to 420 nm for several seconds. Compared with thermosetting packaging materials, it not only reduces the damage to the pigment caused by heat, but also improves the production efficiency. This UV curable acrylic resin also has low moisture permeability and is not easily eroded by the electrolyte. After 1000 hours of high temperature endurance test, the performance retention rate of over 95% can still be achieved. In addition, because the packaging material is liquid, screen printing and dispensing methods can be used to meet the needs of a variety of shapes.
Deep groove Ball Bearing is the most representative structure in rolling bearing, which is widely used. In addition to radial load, this kind of bearing can also be loaded with bidirectional axial load. The friction torque is small, and it is most suitable for adjusting rotation, low noise and low vibration. Bearings are widely used in automobile, electrical, instrumentation, construction machinery, agricultural machinery and various professional machinery. This kind of bearing has open and closed deformation structure.
Deep groove ball bearings consist of an inner and outer ring with a cage containing a complement of precision balls. The standard Conrad-type bearing has a deep-groove construction capable of handling radial and axial loads from either direction in versatile designs that permit relatively high-speed operation.
