Resistance of Marine Airbags

1.High resistance to soft pressure: when the marine airbag moves on the bottom of the boat, it will be squeezed by the bottom and the ground. Due to the uneven rolling speed, the airbag will be twisted and deformed. This complex deformation phenomenon of extrusion and twisting can be described by “kneading and pressing” movement. When the pressure movement occurs, the local wall of the airbag will wrinkle, and under the concentrated stress of the wrinkles, the local wall of the airbag will wrinkle. Lamellar tearing of the multilayered fibrous wall can easily lead to rupture of the fibers within the wall and rupture of the entire balloon.

2. New structure explosion-proof design: After the working pressure of the airbag increases, the possibility of air leakage at the end of the marine airbag and the rubber joint also increases. After the airbag is used repeatedly, once the end leaks and operates under high pressure, the end of the airbag is very easy to explode and cause injury.

3. Structural optimization layout: The principle of structural optimization layout is to determine the size and direction of the main stress during the working process of the airbag, and then adjust the angle of each layer of cords to make the force of each layer of cords in the airbag wall reach a general balance, so that the The efficiency of the reinforcing fibers is maximized.

4. Durability and wear resistance: Marine airbags work in very harsh environments, exposed to sunlight, and may be exposed to sea water, gravel, and various pollutants. The surface of the airbag must be wearable, resistant to seawater and various chemical substances, and resistant to aging. The body rubber airbag with high load-bearing capacity uses natural rubber as the main raw material, and various auxiliary materials are added through a reasonable formula, and its durability has been proved by tests.

5. Higher flexibility and shock absorption capacity: the inflatable marine rubber airbag adopts a unique overall winding process, after low temperature and long-term vulcanization, the wall thickness of the capsule is uniform, and there is no secondary joint caused by overlapping. Therefore, under the premise of the same strength, the inflatable rubber airbag can become thinner, softer and more elastic.
