[China paint information] learned from the 2011 International anti-corrosion paint technology development forum a few days ago, The antifouling paint technology and products jointly developed by Dalian Yuxiang technology group and the Chinese Academy of Sciences took the lead in obtaining the "world pass" in China. They have not only passed the certification of China Classification Society, but also passed the most stringent international certifications such as det Norske Veritas and Lloyd's register of shipping. This will change the situation that antifouling paint on the bottom of domestic shipbuilding is monopolized by foreign enterprises

the bottom of the ship has been soaked in seawater for a long time, so the key technology of antifouling paint on the bottom of the ship has always been the "commanding point" of anti-corrosion technology. According to sun Lianying, President of the China Paint Industry Association, the anti-corrosion paint on the bottom of foreign ships of ocean going ships generally needs to be applied once a year, and the self-developed anti-corrosion paint on the bottom of ships by our country is a landmark change. The anti-corrosion paint on the bottom of ships has excellent quality and can be applied once every two to three years, with strong corrosion resistance and greatly improved service life

it is understood that the strong anti-corrosion function comes from nanotechnology, which is also the "uniqueness" of China's research and development of antifouling paint for ship bottom. On the other hand, foreign ship bottom antifouling paint generally needs to add chemical agents, and the paint itself and waste cause certain pollution to the sea. The ship bottom antifouling paint developed in China also represents the development direction of the more environmentally friendly international paint industry because of the use of nanotechnology

in 2009, Dalian Yuxiang technology group should undertake no more than 1% of the national science and technology support plan project "research and development of coatings and key technologies for ships and large-scale offshore engineering". The company and the Chinese Academy of Sciences jointly use nanotechnology to develop three series of products and supporting demonstration projects: a new generation of marine antifouling coatings for ships, a new generation of high-performance ballast tank coatings, and nano heavy-duty anti-corrosion coatings for offshore platforms. At present, this key technology product with independent intellectual property rights has entered the trial production stage, and it is expected to be fully invested in the production of aluminum alloy with various shapes of parts during the "12th Five Year Plan"
