The appraisal committee heard the report on the development of the subject, carefully reviewed the relevant technical materials, and conducted on-site blasting tests of the airbags. After questioning and discussion, the experts at the meeting formed a consistent appraisal conclusion: the project theme is clear, the technical route is feasible, and the experiment The program is reasonable, the test data is reliable, and the conclusion is accurate. The product has good social and economic benefits, and is the first in China and abroad, reaching the international advanced level. The product was successfully developed. It is of great significance to reduce the cost of water discharge in China's shipbuilding industry.
The development of high-capacity multi-layer pressure airbag is based on the new concept of "pressure airbag" and its damage mechanism based on the double action of airbag under the movement of the underbody under the ship. A new rubber formulation that is beneficial to improve the adhesion between fiber layers, a new process of "low temperature and long time" vulcanization, a new method of double-sided pressing and a new anti-explosion structure for the head. Since the new high-capacity multi-layer pressurized airbags developed by Jinan Changlin Airbag Container Factory has been put into the market, it has successfully launched more than 10 10,000-ton ships with a weight of more than 5,000 tons. The independent innovation and technological progress of airbag launching have made new contributions.
