Recently, the chemical business unit of Korea BN Steel Co., Ltd. and Hyundai Heavy Industries and Korea Science and Technology Institute (KAIST) have used the graphene, which is known as the “new material of dreamsâ€, to develop damping materials for ships and successfully mass-produced them. .
It is reported that the damping material is mainly used for the engine propeller of the ship, which can eliminate noise and vibration. In addition, it is also used in equipment for reducing noise in areas such as cabins and cabins where crew members live.
In June 2015, the chemical business unit of Korea BN Steel Co., Ltd. began to participate in the research and development of vibration-damping materials for ships with Hyundai Heavy Industries and Korea Science and Technology Institute. In June 2017, it passed the application test at the modern heavy industry mooring dock, which showed superior performance compared with imported products, which can reduce the noise and vibration in the low frequency region below 200.
Graphene is the main material of the damping material. Its electrical conductivity is more than 100 times higher than that of copper. Its strength is 200 times higher than that of steel. However, it has good elasticity and can be folded or bent.
According to Hyundai Heavy Industries, in June 2017, the use of graphene damping materials on the 300,000-ton super large crude oil carrier (VLCC) can reduce vibration and noise by more than 50%, and the installation cost is lower than existing products. It is also expected to be applied to passenger-vehicle dual-purpose vessels (RO-PAX), submarines, automobiles, trains, construction equipment, aircraft, onshore and offshore equipment, etc., which will help to comprehensively improve the level of Korean manufacturing.
Up to now, the chemical business unit of South Korea's BN Steel has built its own production equipment at the Zhounan plant in Liangshan City. It first demonstrated the graphene damping material at the International Shipbuilding and Marine Industry Exhibition in October 2017.
It has officially supplied to Hyundai Heavy Industries, and will continue to expand production in the next year in order to supply to the Miura Shipyard and Sanhu Shipyard.
Qian Shiyu, director of Korea BN Steel Co., said that the self-developed graphene damping material has achieved world-class vibration and noise reduction effects, and has outstanding advantages in terms of quality and price. Through continuous research and development, the company will be committed to Become a global leader.
